1 Radial Ball Bearing 径向滚珠轴承 Definition & Usage 定义与用途 A bearing is a sliding or rolling component used to reduce friction in a machine. make many of the machines we use today possible. Without bearings, we would be constantly replacing parts that wore out from friction. 轴承在机器里用于减少摩擦力的滑动或滚动零件正是因为有了轴承, 才使我们今天的许多机器能顺利地运转没有了轴承, 我们将要一直地更换因为摩擦而损坏的零件 reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. These balls or rollers bear the load, allowing the device to spin smoothly. Types Single-row deep groove ball bearings are the most common type of rolling bearing, having a wide range of suitable applications. The raceway grooves on both inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be applied in either direction. Because of their low torque, they offer high-speed operation with low power loss. 夹轴承提供光滑的内和外金属表面, 让同样光滑的金属球或卷轴滚动, 从而减少摩擦力这些金属球或卷轴能承受载重量, 使设备顺利地旋转类型单排深槽式轴承是最普遍的转动轴承它具有广大的使用范围, 在环内外两侧的凹槽轨道有比球的半径稍微大一点的圆弧加上半径负载, 轴向负载可以被运用在任何方向上由于他们的低转力矩, 所以他们可以在高速度的运行中只损失少量的能量 199

2 Bearing Symbol Description 轴承符号种类 Miniature and flanged bearings are made with high levels of precision. Therefore these are generally used in applications where accurate rotational performance and low torque is necessary, and load capacity is a secondary issue. Often, a shield or seal is installed to retain lubricant and to prevent contamination from entering the bearing raceways. These are available in a variety of materials and configurations. Care & Maintenance 微小和均以高水平的精确度制造因此它们一般被运用在需要精确旋转和低力矩的应用负载容量则是次要的问题为了保持润滑剂的作用和阻止污染物进入轴承轨道, 我们通常安装一防护罩或者密封条这些防护罩或密封条有多样化的原料和结构照料于维护 d D B B 1 D f B f B f1 C r C or Bearing bore (inner diameter) Bearing outer diameter Open bearing width Flange Bearing width Bearing outer diameter (includes flange diameter) Open bearing flange width Shield bearing flange width Radial basic dynamic load rating Basic static load rating d 轴承孔 ( 内直径 ) D 轴承外直径 B 开口轴承宽度 B 1 法兰轴承宽度 D f 轴承外直径 ( 包括法兰尺寸 ) B f 开口轴承法兰宽度 B f1 防护轴承法兰宽度 C r 径向基本动力负载等级基本静态负载等级 C or As with most machine elements, bearings will tend to wear out with use. However, the lifespan of a bearing can be very long if proper care and maintenance is practiced. To extend the lifespan and efficiency of your bearings, always ensure that it Is kept cool and clean. The bearing should be run within the rated load and lubrication should be applied at intervals, depending on usage level and working environments. 同多数的机械元件一样, 轴承也会磨损尽管如此, 如果给于轴轮适合的照料于维护, 他们的是使用期将会很长要使轴承的使用期限延长和效率提高, 一定要将轴承保持干净和阴凉轴承应该在规定的承载量范围内运作, 并且按照使用水平和工作环境, 在间隔给于润滑剂 Conversion Table / 换算表 Disclaimer: All information printed in this publication is for reference only.
