Development of a New Skid Damage Testing System for High Speed Rolling Bearing
高速滚动轴承滑蹭试验系统研制

A new skid damage testing system for high speed rolling bearing is developed and used to study bearing skid damage mechanism under the high speed and ultra high speed conditions. This system can simulate the dynamic contact situation of bearing ring and roller by adjusting the various experiment parameters. It can also study the skid damage rules of high speed rolling bearing. The work principle, structure and main functions of this testing system are systematically introduced in this paper. Taking cylindrical roller bearings as an example and by changing the experiment conditions (slip ratio, inner ring speed, radial load and lubrication), the authors have invetigated the skid damage rules of high speed rolling bearing. Experimental results show that this system is feasible and effective. This system is convenient and easy to extend, which can provide a support for the design and development of ultra high speed and super precision rolling bearing.
