In the following product range, all bearing components and bearing series in the application fields of heavy industry, rail & transportation, energy & power plants, engineering as well as shipbuilding and port technology with their specific characteristics will be presented. 深沟球轴承 深沟球轴承可承受径向和轴向载荷 该轴承是使用最广泛的轴承类型 由于此类轴承允许角度误差有限, 所以需要精确安装 此类轴承应用于许多领域, 主要用于高速运转的机械 深沟球轴承价格低廉, 可靠耐用 Deep Groove Ball Bearings Deep groove ball bearings take up radial and axial forces. They are among the most used bearing types. Due to their limited capability of angular alignment, the bearings must be aligned accurately. They are used in many applications, primarily in machines that operate at high speeds. Deep groove ball bearings are competitively priced and very reliable. 8

9 角接触球轴承, 单列 此类轴承可承受较大的单向轴向力 在施加轴向负荷的情况下能承受离心力 角接触球轴承适用于高转速且不可拆分 Angular Contact Ball Bearings, Single Row This bearing type allows absorption of large axial forces from one direction. Centrifugal forces can also be included, but only while axial loads are acting. Angular contact ball bearings are suitable for high speeds and cannot be dismantled. 角接触球轴承, 双列 双列角接触球轴承相当于 O 型排列的两个单列角接触球轴承, 但安装尺寸更小 在方向变化产生较高的径向载荷和推力载荷的情况下, 经常采用双列角接触球轴承 Angular Contact Ball Bearings, Double Row Double row angular contact ball bearings go together with the arrangement of two single row angular contact ball bearings with O-arrangement but with smaller mounting dimension. Double row angular contact ball bearings are often used, when high radial and thrust loads from changing directions are transferred. 四点接触球轴承 四点接触轴承是单列角接触球轴承的子类, 可承受双向轴向荷载 Q 型四点接触球轴承具有一个分离式外圈 QJ 型四点接触球轴承具有一个分离式内圈 从而确保了其高强度且便于安装的特点 Four Point Bearings Four point bearings are a subgroup of single row angular contact ball bearings which absorb axial loads in both directions. Four point bearings version Q have a divided outer ring. Four point bearings version QJ have a divided inner ring. This concept ensures both high ruggedness and easy installation. 9

10 推力角接触球轴承 推力角接触球轴承是双向承载高精密轴承, 主要结合双列圆柱滚子轴承使用, 其中双列圆柱滚子轴承主要负责承载径向力 推力角接触球轴承便于拆卸和安装 Angular Contact Thrust Ball Bearings Angular contact thrust ball bearings are bilateral effective high precision bearings. They are mainly used in combination with double row cylindrical roller bearings, whereat the double row cylindrical roller bearings are responsible for absorbing radial forces. Angular contact thrust ball bearings are easy to disassemble and mountable. 圆柱滚子轴承, 单列 KRW 生产的单列圆柱滚子轴承主要为高负载型 ( 后缀 E) 圆柱滚子轴承采用钢制 铜制实体或玻璃纤维强化 ( 聚酰胺 ) 保持架 圆柱滚子轴承很容易拆分, 这促进了安装和拆卸的简易化 滚子和滚道之间的修正线接触降低了边缘应力 Cylindrical Roller Bearings, Single Row At KRW single row cylindrical roller bearings are mainly manufactured as heavy-duty version (suffix E). Cylindrical roller bearings come with solid steel, solid brass or glass fibre reinforced plastic (polyamide) cages. Cylindrical roller bearings can be disassembled easily. This facilitates an easy assembly and disassembly. The modified line contact between the rollers and races reduces edge tension. 10

11 圆柱滚子轴承, 双列 双列圆柱滚子轴承截面尺寸小, 具备较高的径向承载能力 能抗扭矩, 刚性较强 带锥形内孔的径向游隙可通过移动内圈方便调整 Cylindrical Roller Bearings, Double Row Double row cylindrical roller bearings feature a low profile and offer a high radial load capacity. They are torsion-resistant and very stiff. The radial clearance for tapered bore is easy to adjust by moving the inner ring. 圆柱滚子轴承, 多列 多列圆柱滚子轴承的一大优点是径向承载能力极高 由于滚动体数量多, 冲击力可均匀分布 其摩擦力小于其他类型的多列轴承 多列圆柱滚子轴承不能承载轴向力 但在运行中允许少量的轴向位移 Cylindrical Roller Bearings, Multi Row A big advantage of multi row cylindrical roller bearings is their very high radial load capacity. Due to the large number of rolling elements the impact force is well distributed. The friction is lower than at other multi row bearing types. Multi row cylindrical roller bearings cannot absorb axial forces. However, in service an axial displacement is possible. 圆柱滚子轴承 ( 满装 ), 单列 满装圆柱滚子轴承能在较低转速下承受极高的载荷 开式单列和双列轴承主要用于齿轮箱中 此类无保持架轴承用代号字母 V 表示 Cylindrical Roller Bearings (Full Complement), Single Row Full complement cylindrical roller bearings can withstand extremely high stresses at lower speeds. Unsealed single and double row bearings are used mainly in gear boxes. These cageless bearings are marked with the code letter V. 圆柱滚子轴承 ( 满装 ), 双列 此类型的满装滚子轴承中, 滚动体由坚固的轴承套圈上的挡边引导 此类轴承的额定载荷高于单列满装滚子轴承 Cylindrical Roller Bearings (Full Complement), Double Row In this type of full complement roller bearings, the rolling elements are guided by flanges on the massive bearing rings. The load rating is higher than for single row full complement roller bearings. 11

12 圆柱滚子轴承 ( 满装 ), 多列 多列满装圆柱滚子轴承非常耐用和坚固 主要用于有非常高的疲劳应力但速度较低的情况下 此类轴承可用作浮动端轴承 固定端轴承或支承轴承 Cylindrical Roller Bearings (Full Complement), Multi Row Multi row full complement cylindrical roller bearings are very viable and very stiff. They are mainly used in applications where very high fatigue stresses occur, but low speeds prevail. They can be used as floating, fixed or step bearings. 轴箱圆柱滚子轴承 轴箱圆柱滚子轴承是连接铁路车辆车轮和其他部分的轴承 轴箱圆柱滚子轴承与普通的圆柱滚子轴承有相似的结构, 根据不同的应用, 轴承保持架可用玻璃纤维强化聚酰胺 (TN) 或黄铜 (M3) 制造 Axle Box Cylindrical Roller Bearings Axle box cylindrical roller bearings act between wheels and other parts of the rail vehicle. Axle box cylindrical roller bearings have a similar structure to normal cylindrical roller bearings. The materials of the cages can be chosen depending on the application, glass fiber reinforced polyamide (TN) or brass (M3). 推力圆柱滚子轴承 由于其设计特点, 推力圆柱滚子轴承占空间小并能承受较高轴向力和冲击负载 此类轴承一般适用于较低速度的情况 由于轴承内部几何因素, 滚子和滚道之间会产生较高的滑动摩擦力, 可通过适当的润滑降低摩擦 得益于其可分离性, 推力圆柱滚子轴承也便于安装 Cylindrical Roller Thrust Bearings Due to their design, cylindrical roller thrust bearings use only little space and are able to take up high axial forces as well as impact loads. They are typically used at relatively low speeds. Due to the bearings internal geometry, high slippage forces are produced between raceway and rollers, which can be reduced by appropriate lubrication. Thanks to their separability, cylindrical roller thrust bearings are easy to install. 圆锥滚子轴承 圆锥滚子轴承主要用于需要高额定载荷且需同时承受轴向荷载和径向荷载的情况 此类轴承通常成对安装 (X 型或 O 型排列 ), 以防轴承分离 圆锥滚子轴承具有一定的速度限制 Tapered Roller Bearings Tapered roller bearings are predominantly used in applications where high load rating is required and where they primarily have to sustain combined radial and axial loads. These bearings are usually installed in pairs (X or O arrangement) to prevent a total discharge of the bearing. Tapered roller bearings are suitable for limited speeds only. 12

13 推力圆锥滚子轴承 推力圆锥滚子轴承能承受非常高的轴向力, 而且尽管轴向空间需求较小, 也能提供良好的抗冲击性能 圆锥滚子轴承非常坚固 Tapered Roller Thrust Bearings Tapered roller thrust bearings can absorb very high axial forces and offer despite their relatively small axial space requirements an optimum shock resistance. Bearings with tapered roller bearings are very stiff. 球面滚子轴承, 单列 该球面滚子轴承是具有可调节接触角的单列滚子轴承 此类轴承特别适用于需要高径向承载能力, 并能补偿偏斜的情况 此类轴承坚固的设计在径向冲击载荷的应用中得到了验证 但是此类球面滚子轴承的轴向承载能力非常低 这种轴承不可拆分 Spherical Roller Bearing, Single Row The spherical roller bearing is a single row roller bearing with adjustable contact angle. This type is especially suited for applications which require high radial load capacity and compensation of misalignment. Their solid design has been proved in applications with radial shock load. The axial load capacity of spherical roller bearings, however, is rather low. These bearings cannot be disassembled. 13

14 球面滚子轴承, 双列 除了带有固定引导挡边或浮动挡边的双列球面滚子轴承,KRW 还生产内圈无挡边的球面滚子轴承 由于其承载能力高, 球面滚子轴承适用于需承受极高荷载的情况 此外, 球面滚子轴承能承受双向轴向力, 具有出色的调心性能, 可消除轴挠曲或轴承座偏斜的影响 Spherical Roller Bearings, Double Row Besides spherical roller bearings double row with predefined guiding lips or floating flanges, KRW manufactures spherical roller bearings without flanges on the inner ring. Because of their high load carrying capacity, spherical roller bearings, double row, are ideally suited for applications where extremely high loads have to be accoodated. Moreover, spherical roller bearings, double row can sustain axial forces in both directions, offering an excellent self aligning capability and are impervious to shaft deflections as well as misalignment of the bearing seats. 推力球面滚子轴承 推力球面滚子轴承是单列轴承, 由于其内部结构, 可以调节角度补偿轴偏斜 坚固的轴圈和座圈以及钢制 钢板或铜制保持架, 保证了其出色的承载能力 推力球面滚子轴承可承受径向力, 并适用于高速运转 Spherical Roller Thrust Bearings Spherical roller thrust bearings are single row bearings which, due to their internal geometry, can adjust their angle to compensate shaft misalignments. Solid shaft washers and housing washers as well as steel, steel plate or brass cages ensure an excellent load capacity. Spherical roller thrust bearings are able to take up radial forces and are suitable for higher speeds. 14

15 绝缘垫圈 轴承绝缘垫圈是安装在驱动轴的相对端, 以避免电气零部件之间发生短路 带有陶瓷涂层的轴承绝缘垫圈能提供相当于 1000 V 的电击保护和大于 50 MΩ 的绝缘电阻 Current Insulated Washers To avoid short circuits between electrical parts, bearing insulating washers are mounted on the opposite side of the drive shaft. The ceramic coating of bearing insulating washers offers an electrical shock protection up to 1000 V and an insulation resistance of more than 50 MΩ. 绝缘轴承 滚动轴承外圈的外径面 圆角和端面有一层 70μm 或 140μm 厚的氧化陶瓷绝缘涂层, 保护轴承和周边部件免受电流损伤 不需要采用其他繁琐的绝缘措施 KRW 为所有轴承类型提供高达 500 V(SJ5) 至 1000 V(SJ10) 的绝缘防护 Current Insulated Bearings A 70 μm or 140 μm thick oxide ceramic insulating layer on the outer surface, the rounded edges and the flat surfaces of the outer ring of a roller bearing protects the bearings and surrounding components from damage by electrical power. Other elaborate conventional isolation methods are not necessary. KRW provides power isolation up to 500 V (SJ5) and up to 1000 V (SJ10) for all types of bearings. 紧定套 紧定套用于将带锥孔 ( 锥度为 1 : 12 和 1 : 30 ) 的圆柱 球面和双列球面滚子轴承固定在轴上 此外, 可以用紧定套调整每个轴承的径向游隙 这允许轴径具有较大公差 Clamping Sleeves Clamping sleeves are used to fix cylindrical, spherical and spherical roller bearings double row with tapered bore (taper: 1 : 12 and 1: 30) on shafts. In addition, the radial clearance of each bearing can be adjusted by using clamping sleeves. This allows larger tolerances of the shaft diameter. 退卸套 退卸套用于配合锥型孔 ( 锥度分别为 1 : 12 和 1 : 30) 的圆柱滚子轴承 单列和双列球面滚子轴承固定在圆柱轴上 滚动轴承靠在轴肩上, 用相应工具将退卸套压入锥型孔中 根据 DIN 5416 标准, 为 480 以下轴颈配套的退卸套是标准件 Withdrawal Sleeves Withdrawal sleeves are used to attach cylindrical roller, single row and double row spherical roller bearings with tapered bore (taper: 1 : 12 or 1 : 30, respectively) on cylindrical shafts. The roller bearing rests on the shaft shoulder, the puller sleeve is pressed into the taper bore using suitable tools. Withdrawal sleeves are standardized components below a shaft diameter of d W = 480 according to DIN

16 角圈 KRW 生产 NU 和 NJ 系列的圆柱滚子轴承角圈 通常情况下角圈是由高碳铬钢制成 Angle Rings KRW manufactures angle rings for cylindrical roller bearings, series NU and NJ.

The bearings will be manufactured with logarithmical profiles. Thanks to the special KRW manufacturing process a high degree of precision by production of the rolling-elements will be achieved. 17

18 产品范围 - 特殊轴承 Product Range Special Bearings 除了生产各类标准轴承外,KRW 公司还不断提供各种特种轴承 特种滚子轴承因特定工况的特性要求而产生 In addition to manufacturing a wide range of standard bearings KRW Leipzig GmbH increasingly provides special bearings too. Special types of roller bearings are particularly necessary when certain conditions demand special properties of a bearing type. KRW 与客户一起定义性能要求, 预估特定工况下的技术要求 ; 然后 KRW 的工程师将设计出特种轴承的各个部件 Together with the customer, KRW creates a job profile, in which anticipated specific conditions of the application are taken into account. Secondly KRW engineers individually design each component of the special bearing. 在此之后, 每个部件都将在 KRW 的德国工厂里生产并组装 通过过去和目前进行的大量特殊应用条件下的特殊轴承设计和开发,KRW 积累了丰富的经验, 同时反映在 KRW 产品的高品质中 Then, the bearing components are exclusively manufactured and mounted by KRW in Germany. Through the successful use of a variety of special designs in various fields in the past and the present KRW now has a considerable amount of experience, reflecting the quality of all bearing products from KRW. 薄壁轴承 薄壁轴承主要应用于格外需要节约空间和轻量化设计的情况 薄壁轴承为单列深沟球轴承 角接触球轴承或四点接触球轴承 Thin Section Bearings Mainly for particularly space- and weightsaving design thin section bearings are used. Thin section bearings are manufactured as single row deep groove bearings, angular contact ball bearings or four-point bearings. 18

19 圆柱滚子轴承, 支柱钢保持架 承受高载荷的圆柱滚子轴承通常采用支柱钢保持架 滚动体是中空的滚子通过支柱引导 此类轴承有单列 双列或多列滚子形式 Cylindrical Roller Bearings, Steel Pin Cage Cylindrical roller bearings, which have to endure high loads, often feature pin type steel cages. Hollow rollers which are guided over the cage pins serve as rolling elements. They are available as single-, double- or multi-row bearings. 圆锥滚子轴承, 支柱钢保持架 对于长期承受径向重载荷和单向轴向载荷的轴承, 非常适合采用带支柱保持架的圆锥滚子轴承 此类轴承额定负载高, 并且圆锥滚子和滚道之间为修正线接触, 可避免边缘应力 由于此类轴承只能向反方向调整因而只能成对安装 Tapered Roller Bearings, Steel Pin Cage For heavy long term bearing locations with combined forces from radial- and single-sided axial directions, tapered roller bearings with cage bolts are very suitable. They have high load ratings and are equipped with modified contact lines between the tapered rollers and the raceways which prevent edge stresses. Because of adjusting bearings in opposition these bearings are exclusively installed in pairs. 19

20 圆锥滚子轴承, 多列 双列圆锥滚子轴承以国际标准生产 :TDI ( 双内圈 ) 和 TDO( 双外圈 ) 其均比单列圆锥滚子轴承可更加便捷地安装和调整 这两种轴承设计都具有较高刚度, 并可承受高负荷和复合载荷 TDO 轴承适用于刚性引导 ; 而 TDI 轴承则用于轴上柔性引导 四列圆锥滚子轴承由一对双列或组合了单列和双列圆锥滚子轴承构成 此类轴承主要用于热轧机支撑辊 Tapered Roller Bearings, Multi Row Double row tapered roller bearings are manufactured to international standards: TDI (two cups and one cone) and TDO (two cones and one cup). They can be mounted and adjusted more easily than matched single row tapered roller bearings. Bearings of both designs are rigid and can take up high loads as well as combined loads. TDO bearings are used for rigid guidance, whereas TDI bearings are used for the flexible guidance of shafts. Four row tapered roller bearings consist either of matched double row or combined single row and double row tapered roller bearings. This bearing type is mainly used for supporting rolls in hot rolling stands. 背衬轴承和滚轮轴承 背衬轴承是外圈厚壁圆柱轴承, 旋转精度非常高 此类轴承的厚壁外圈是适应重负荷要求, 主要应用于多辊轧机 为保证轴承能够在运行周期内满足运行工况要求, 滚子和滚道接触区域需采用对数曲线轮廓 Support Rollers and Cam Rollers Support rollers are cylindrical roller bearings with a thick-walled outer ring and a very high running accuracy. The bearings have particularly thick-walled outer rings to accoodate the high loads. They are used primarily in cluster mills. To ensure that the bearings can withstand the prevailing operating conditions for the required period of time, the roller-raceway contact area features a logarithmic profile. 三键轴承 三键轴承用于造纸设备抗挠曲支撑辊驱动端, 也可用于轧机 轧辊与中心圈以螺栓连接, 内圈和外圈固定 Triple Ring Bearings Triple ring bearings are used for supporting anti-deflection rolls at the drive end of paper machines.

22 重工业 Heavy Industry 在各类重工业领域里, 球轴承和滚子轴承承担着重要角色, 特别是原材料提取, 冶金以及型材等领域 高品质轴承和轴承零部件能确保各类技术应用设备的高效 长寿命和高产出 In the scope of heavy industry ball and roller bearings take on important tasks and are essential for bearings in the field of raw materials extraction, metallurgy, as well as in metal forming. High-quality bearings and bearing components contribute a high efficiency, long life and maximum efficiency of machines in a variety of technical applications. 轮斗铲 在这种矿物开采设备中应用了多种不同类型的轴承 支撑轮斗主轴的轴承需受高载荷和大冲击力 此外, 轴承还必须能补偿轴挠曲和角偏差 轴承设计寿命应尽可能长, 以最大程度减少维护或修理工作所需的时间 Bucket Wheel Excavators Many different bearing types are used in these raw material extraction machines. The bearings that support the bucket wheel shaft are subjected to high loads and heavy shocks. Moreover, the bearings must be able to compensate for shaft deflections and angular misalignments. The bearings are designed for the longest possible service life to minimize disruptions for maintenance or repair work. 22

23 钻机 在水平钻孔 倾斜钻孔或垂直钻孔中, 都需要保证钻机和钻头导向的稳定 钻机中的滚动轴承必须能承受强大的振动应力 冲击载荷和波动载荷 运行精度非常高的轴向和径向主轴轴承多用于这一应用 Drills In the application of drilling with horizontal, diagonal or vertical propulsion, a constant guidance of the drill and the drill head is necessary. Rolling bearings for drills must withstand high vibratory stresses, heavy shock loads as well as dynamic forces. Axial and radial spindle bearings of very high running accuracy are used for this application. 泵 在这一应用领域需要多种类型的轴承, 轴承类型的选用取决于泵的具体构造和工作方式 轴承所需承受的负荷包括径向力和轴向力, 以及循环径向加速度产生的复合力作用 经常采用具有高度耐用性能的标准轴承和特种轴承 KRW 研制了专门用于泵的四点接触球轴承系列产品 Pumps In this field of application, various rolling bearing types are used, depending on a specific pump s construction and principle of operation. The loads that have to be accoodated by the bearings range from exclusive axial and radial forces to effects of combined forces produced by circulating radial accelerations. There are often used standard bearings and special bearings which provide high durability. 23

24 管磨机 水平磨机用于破碎矿物 矿石 煤炭和水泥熟料 通过冲击和研磨细化原料 管磨机可达 20 米长, 以相对较低的速度运转 这意味着所采用的轴承必须适应轴不对中并能承受长期振动载荷 Tube Mills Horizontal mills are used for the crushing of minerals, ores, coal and cement clinker. The raw material is pulverized by beating and grinding. Tube mills can have a length up to 20 meters and operate at relatively low speeds. That means the bearings used must accoodate misalignments and withstand the permanent vibration. Picture: Polysus AG (Stahl-Zentrum) 输送机 / 运输系统 在通常包括几大部分 ( 例如驱动机构和传送带 ) 的运输系统中, 轴承经常需要承受高速度和剧烈波动的负载 此外, 这种工作环境 ( 矿业 ) 中的轴承经常暴露在污染程度不断恶化和较大污染水平的环境中 Conveyors / Transportation Systems In these systems, which usually consist of several elements (e. g. drive train and conveyor belt), bearings often have to accoodate high speeds and greatly fluctuating loads. In addition, the rolling bearings for this work environment (mining) are often exposed to increased contamination and pollution levels in their iediate surroundings. 24

25 破碎机 破碎机是一种利用高压力把物料细化成小颗粒的机械 偏心轴和摇臂要承受极高的载荷, 故其所用轴承必须同时具有高韧性和高动载荷承载能力 Crushers Crushers are machines that reduce raw materials to smaller grain sizes by exerting high pressure. The eccentric shaft and the rocker bars are subjected to extremely high loads, which must be taken up by bearings that combine the greatest possible flexibility with high dynamic load carrying capacity. 振动筛 振动筛 ( 或震动筛 ) 用于分选物料, 在原料提取和处理中属于受力状况最恶劣的机械之一 在该设备中采用特殊结构设计的滚动轴承以使磨损最小化 Shaking Screens Shaking screens (vibrating screens) are used for grading bulk material and are among the most severely stressed machines in the area of raw material extraction and processing. Rolling bearings with special design shapes contribute to minimize wear in these machines. 立磨机 立磨机用于将原料研磨和处理成既定的粒度 立磨机 ( 也称作球磨机 ) 所采用的轴承, 必须能承受高速运转和交变力的作用 Vertical Mills Vertical mills are used for the grinding and processing of a raw material to the desired grain size. The bearings used in these mills, which are also referred as bowl mill units, must be suitable for high speeds and the effects of changing forces.

These support rollers in turn are supported in spherical roller bearings. 转炉 耳轴承和大齿轮轴承是转炉的支撑部件, 必须能在转数极低的情况下承受高荷载 其应用工况极端恶劣 ( 高温 粉尘 ), 因此这些轴承必须和其他配合部件一起良好密封 Converters Trunnion bearings and bull gear bearings are the supporting units of converters. They must withstand a high load at a very low number of revolutions. Since they are used in extreme conditions like heat and dirt, these bearings must, among other things, be well sealed.

This means that the bearings installed in the mill must consist of materials that are both hard and tough. The rolling stock travels through the rolling mill at velocities of up to 120 m s. This requires an additional compromise regarding the rotation speed when selecting the bearings. Picture: Saarstahl 27
