双列角接触球轴承预紧力分析

Preload Analysis of Double Row Angular Contact Ball Bearing

为使双列角接触球轴承的使用性能得到充分保证 ,必须对其施加一定的预紧力。同时 ,主机对此类轴承多有高灵敏度和低摩擦力矩的要求 ,那么对其施加的预紧力必须准确 ,通过实际测量和理论计算可以达到这一要求。附图7幅 ,参考文献

In order to make fully ensure for utilizing performance of double row angular contact ball bearings, the preload must be applied on them. Because many host machines have the demands of high sensitivity and low friction moment for the kind of bearings, the preload applied on it must be accurate. By calculating and actual measuring, these demands may be realized.
