差载轴承用于汽车轮毂轴承的设计及其可靠性研究浅析

为了不断提高轴承的寿命与精度,目前轴承所使用的材料、设备、工艺都有了飞跃的发展.轴承加工单位在不断提高这些加工精度与研发材料达到某个极限时,不得不从轴承设计角度上对通用轴承进行创新.由于“差载轴承”属新型轴承产品,尚无详细的寿命及其精度方面的理论分析,以汽车轮毂轴承为主要事例,就该新轴承相对传统结构的轴承,有效提高了寿命与极限转速,做了表浅性研究分析,为行业提供参考和借鉴.

Design and Reliability Research of Differential-Ring Bearing Contained for Automotive Wheel

In order to continuously improve the life expectancy of bearings and precision, the materials used for bearing, its processingequipment and techniques have a great leap in the development. When bearing manufacturer in tile continuous development of the machining accuracy and the material reached a certain linfit, innovation had to be done to the general bearing from the side of designing. I）ue to ＂＇ Differential-Ring Bearing＂ was a new concept kind of bearing, there was no details of the life accuracy of theoretical analysis yet. By auto wheel bearings as the main examples, a superficial analysis and research were made to this new bearing as compared to bearing of traditional structure, which effectively improved the life and speed limit. The role of guide to search will be played.
