球轴承沟道精研机工装改进

Improvement of implement of lapping machining with grooved raceway of ball bearing

为了降低大型球轴承加工过程中外沟道和内沟道的表面粗糙度,改进了精研机工装,扩大了加工范围,替代手工抛光,保证Ra值和精度满足工艺技术要求。从而降低了轴承的振动和噪音,使其50%以上达到Z2组振动值要求,满足了轴承市场的需要。

In order to reduce surface roughness of inner ring grooved raceway and outer ring grooved raceway of large ball bearing, implement of the lapping machine is improved, the productive kinds is extended, work lap is replaced, it is ensured that Ra value and accuracy satisfy technological request. Vibration value and noise of bearing are reduced, over 50% bearing's vibration value achieve Z2 grade, need of bearing market is satisfied.
