摘要/Abstract

摘要：

高速工况下,轴承摩擦发热量剧增，因此预测球在内外圈滚道的滑动和自旋摩擦功率对高速球轴承的选用、分析和优化意义重大。用刚柔混合动力学有限元法仿真高速混合球轴承,结果显示,轴向载荷从16kN到24kN、内圈转速在较大范围内变化时，球在内外圈的旋滚比（球自旋角速度与滚动角速度之比）、自旋摩擦功率分别大致相等，分析高速混合球轴承滑动与自旋摩擦功率时不宜忽略球在外圈的旋滚比。适当增加轴向预载可以显著减小内圈旋滚比。

Abstract:

The rapidly increased heat generation of high speed hybrid ball bearing draws a need of predicting skid and spin power loss of the bearing. A hybrid dynamic finite element method was proposed to simulate high speed hybrid ball bearings. The results show that when axial load varies from 16kN to 24kN and shaft speed varies in a large range, the spin-to-roll ratio and the spin power loss of outer race is close to that of inner race. It is not appropriate to ignore the spin-to-roll ratio of outer race when predicting the skid and spin power loss of the bearing. A proper preload may decrease the spin-to-roll ratio of inner race efficiently.

Key words: high speed hybrid ball bearing, skid, spin power loss, finite element method
