26 SA 精密交叉滚子轴承相配合部位的设计 SA Precision Cross-roller bearing designing the match parts 由于交叉滚子轴承的紧凑结构和薄壁原因, 在设计其配合机构和压紧法兰时应特别注意 : 对于双外圈或双内圈结构, 轴承座孔的刚度不够, 法兰或压紧螺栓会导致轴承运转不畅甚至内圈或外圈卡死 ; 同时当机构承受负荷会造成轴承变形, 严重影响轴承性能及寿命 Since the Cross-roller bearing is a compact, thin device, special consideration must be given to the rigidity of the housing and the presser flange. With the types having a separable outer ring, insufficiency in the strength of the housing, pressure flange or the presser bolt will result in the inability to evenly hold the inner or outer ring, or the deformation of the bearing when a moment load is applied. Consequently, the contact area of the rollers will become uneven, causing the bearing s performance to significantly deteriorate. 推荐的结构配置 Recommended structure 图 4 外圈旋转推荐结构形式 Outer ring rotation 图 5 内圈旋转推荐结构形式 Inner ring rotation 图 6 内 外圈都旋转同方向固定形式 Both inner/outer ring rotation in same direction 轴承相配合结构件要求 Bearing match parts requirement 轴承内圈带螺纹安装孔 Ring removal tapped hole 轴承外圈带螺纹安装孔 Ring removal tapped hole 图 7(Fig7) 对于精密交叉滚子轴承对相关配合结构件的要求必须保证具有足够的刚度 如上图所示的普通型交叉滚子轴承对外圈支承座的壁厚 T 的要求必须保证 : The match parts of Cross-roller bearing must make sure it have enough rigidity, Refer to above Fig7 shows the normal cross-roller bearing housing thickness T must make sure: 26

When removing the outer ring, do not press the inner ring, or vise versa. 图 8 (Fig8) 对轴承端面上 下固定法兰的要求如上图所示, 其中 Bearing upper and lower presser flange as show on Fig8 F=B 0.5~B 1.2 法兰的厚度 Flange thickness H=B 支承座的高度 Housing height S=0.5mm 法兰压面与轴承和支承座端面分别压紧预留间隙 Clearance of the flange and housing 设计压紧法兰的厚度 (F) 和法兰与配合面的间隙 (S) 按照以上的公式计算 ; 螺栓的数量, 原则是螺栓越多机构越稳固 通常情况下按照后节所说明的螺栓数均布 轴承座和轴的材料是轻质的铝, 我们推荐钢制的法兰 只有保证轴承相配合部件足够的刚度, 而且其中压紧法兰面与支承座和轴承端面的接触面之间必须分隔, 留有一定的间隙 S, 这样才可以保证轴承端面压紧后不会因为部件结构刚性不足而造成相应的变形影响轴承的旋转精度和灵活性 The presser thickness F and the clearance of flange and housing S are obtained from above equation;as for the number of presser bolts,the greater the number of the bolts,the more stable the system becomes.as a guide,however,it is normally appropriate to use the number of bolts indicated in following instruction. Even if the bearing housing and the shaft are made of light alloy, it is recommendable to select a steel-based material for the presser flange. Make sure the bearing match parts have enough rigidity,and also must have a clearance S between presser flange and bearing housing,it is to make sure the bearing will not deformation caused by the less-rigidity of match parts,which will not effect the bearing rotation precision and flexibility. 27

30 SA 精密交叉滚子轴承的安装 : SA Precision cross-roller bearing assembly 安装交叉滚子轴承时请按以下程序进行 When assembling the cross-roller bearing,follow the steps below. 1. 安装前零部件的检查 Inspecting the parts before assembling them 将轴承座或其它的安装零部件进行洗净, 消除污垢, 并确认各零部件的毛刺是否已被除去 Throughly clean the housing and other parts to be assembled,and check if there is no burr or knots. 2. 往轴承座或轴里装入 Installing the cross-roller bearing into the housing or onto the shaft. 由于是薄壁轴承, 装入时易发生倾斜, 请用塑料锤等一边找平, 一边在圆周方向均匀地敲打, 一点一点地装入, 直到能通过声音确认与接触面完全地靠紧时为止 Since the cross-roller bearing is a thin bearing, it tends to tilt as it is installed. To prevent it, gradually drive the cross-roller bearing into the housing or onto the shaft by gently hitting it with a plastic hammer while keeping it horizontal.be sure to keep hammering it with much care until you hear it fully contact the reference surface. 图 9 螺栓在紧固时参考以上顺序用 2-3 个循环交叉拧紧螺栓 Fig 9 Tighening sequence by 2 or 3 repeat 3. 侧面压紧法兰盘的安装 Attaching the presser flange 1) 将侧面压紧法兰盘放置到位后, 将其在圆周方向来回摇动几次, 以调整安装螺栓的位置 Placing the presser flange onto the cross-roller bearing.rock the flange several times to match the bolt holes. 2) 安装压紧螺栓 用手拧螺栓时, 确认没有因螺栓孔偏离引起螺栓难以拧入 Insert the presser bolts into the holes.manually turn the bolts and make sure they do not show skewing caused by misalignment of the bolts. 3) 压紧螺栓的拧紧由暂时拧紧到正式拧紧要分为 3-4 个阶段, 按对角线的顺序反复拧紧 在拧紧被分成两半分割的内圈或外圈的压紧螺栓时, 拧紧过程中经常将一体型的外圈或内圈稍微转动一下, 就能使两半分割部分的偏离得到修正 Fasten the presser bolts in three to four steps from temporary to full fastening by repeatedly securing the bolts in the diagonal order, as shown in Fig9. When tightening the separable inner or outer ring, slightly turning the integral outer or inner ring will correct the dislocation between the ring and the body. 30

31 SA 精密交叉滚子轴承润滑 : SA Precision cross-roller bearing lubrication 在交叉滚子轴承中, 因已全部装入了优质的 2 号锂基润滑脂, 所以到货后就可直接使用 但是, 与一般的滚子轴承相比, 内部空间容积少, 并且充分的润滑剂对于该种结构滚子与滚道面比较紧密接触的结构来说是至关重要, 故必需定期补充润滑脂 补充润滑脂是通过设在内外圈上的, 与油沟相连接的润滑油孔来进行的 补充间隔通常要求是, 即使旋转频率少时, 也为每 6 个月到 12 个月 补充润滑脂时, 请用同种的润滑脂补充到轴承内部的每个地方 对于高频率旋转的场合, 根据使用要求, 更要缩短再润滑周期 同时, 润滑脂被装满后, 由于润滑脂的阻力, 轴承初期旋转时扭矩会短时间地增大, 等多余的润滑脂由密封部位溢出后, 就会回到正常的扭矩值 另外, 在超薄型的轴承中, 没有设置油沟, 请在与轴承配合部位设置相应油沟, 以便于及时补充润滑油脂 Since each Cross-roller bearing unit contains high-quality lithium soap group grease No.2, you can start using the product without replenishing grease.however, the product requires regular lubrication since it has a smaller internal space than ordinary roller bearings and because the rollers need frequent lubrication due to their rolling contact structure. To replenish grease, it is necessary to secure greasing holes that lead to the oil grooves formed on the inner and outer rings. As for the lubrication interval, normally replenish grease of the same group so that it is distributed throughout the interior of the bearing at least every six to 12 months. In locations of high frequency rotation,it must shorten the lubrication interval. When the bearing is filled up with grease, the initial rotational torque temporarily increases. However, surplus grease will run off of the seals and the torque will return to the normal level in a short period. The thin type does not have an oil groove. Secure an oil groove inside of the housing for lubrication. SA 精密交叉滚子轴承使用时注意事项 : SA Precision cross-roller bearing Note on use 被分成两半的内圈或外圈是用特殊的铆钉或螺栓 螺母固定后不可分开的 直接装入轴承座中使用 同时, 如果间隔保持器的再装配出错, 对轴承的旋转性能会有很大的影响 所以请用户不要随便将轴承拆开 1) 内圈或外圈的接合处有时会多少有些偏离, 在装入轴承座之前, 请将固定内圈或外圈的螺栓松动, 用塑料锤进行修正后再安装 ( 固定铆钉会随着轴承座而产生变形 ) 2) 安装或拆卸时, 请不要给固定铆钉或螺栓施加外力 3) 请注意安装零部件的尺寸公差, 使侧面压紧法兰盘能从侧面将内圈或外圈结实地压紧 The separable inner or outer ring is fastened in place using special rivets,bolts or nuts when delivered.when installing it to the system, do not disassemble it.also, erroneously installing the spacer or retainer will significantly affect the rotational performance of the system.so,please do not disassemble the bearing. 1)The matching mark of the inner or outer ring may be slightly misaligned when delivered. In that case, loosen the bolts that secure the inner or outer ring,and correct the alignment using a plastic hammer or the like, before installing it to the housing.(let the securing rivets follow the housing) 2)When installing or removing the Cross-roller bearing, do not apply force to the fixing rivets or the bolts. 3)When mounting the presser flange, take into account the dimensional tolerances of the parts so that the flange firmly holds the inner and outer ring from the side. 31

32 精密交叉滚子轴承 PRECISION CROSS-ROLLER BEARING 交叉圆柱滚子轴承是在内圈和外圈之间 1:1 配置相应的滚子而组成 结构紧凑, 滚动面为线接触, 因此轴承受力时套圈与滚动体弹性变形小, 同时承载径向 轴向负荷及力矩负荷等联合负荷 此类轴承被广泛用于需要高刚性和高旋转精度而又对轴承尺寸要求较小的场合, 比如工业机器人 机床及医疗设备等的回转位置 交叉圆柱滚子轴承内滚动体之间有保持架 隔离块及满滚子型等多种结构, 根据使用场合进行选用, 带隔离块适合于回转力矩较小 转速较高的场合, 满装滚子型结构适合于低转速较重负荷的场合 交叉圆柱滚子轴承具有密封型结构, 是在轴承两侧装有特殊橡胶的密封圈, 对防尘和润滑脂漏泄具有良好的密封效果 我公司现生产可替代 IKO THK INA 等公司轴承产品的 RB SX RE RA XV CRBH CRBS CRBC RU CRBF 等系列, 根据使用要求可选择带安装孔 带保持架 带隔离块或满滚子及双面密封等多种结构, 精度等级最高可以达到 P2 级 Cross-roller bearing with the compact structure of cylindrical roller are arranged 1:1 placed between inner ring and outer ring. Rollers and groove are linear contact. Rings and rollers have small elastic deformation when the bearing achieve loads, Meanwhile, It can achieve radial load, axial load, tilting moment and other combined loads.the Cross-roller bearings are widely used in locations where need high rigidity and high rotation speed but also required minimum size, Such as joints and swiveling units of industrial robots, the swiveling center of machine tools and medical equipment etc. Cross-roller bearing have variety types such as cage or spacer between rollers, full complement cylindrical rollers. Selection is depend on working conditions. The structure with spacer type is optimal for application with small turning moment, high rotation. Full complement types is optimal for application with lower rotation speed and heavier loads. Cross-roller bearing have seal types, which have special rubber seal on both sides, it have good sealing effect for anti-dust and grease leak. SA can produce and replace the bearings of IKO,THK INA, types are RB SX RE RA XV CRBH CRBS CRBC RU CRBF etc. According to the operating requirements to select different types, such as mounting hole type, cage type, spacer type, full complement cylindrical roller type, double seal type etc, the precision can reach to P2. 32
