试样球径变化对载荷偏角的影响分析
Analysis of Load Angle Caused by Test Ball Diameter Change
摘要
Abstract
This paper proposed the relationship between the magnitude of load angle and the test ball diameter by geometric analytical method, based on the accelerated pure rolling contact fatigue test rig with three contact points for the life test of bearing ball. The results of application examples under the condition of different design diameters and offset distances of the loading mechanism pivot point show the load angle can be lowed down less than 0. 106° when the design radius (test ball) is 6mm and the offset distance is 0, and the test ball diameters range from φ 9mm to φ15mm. The larger the load angle magnitude is allowed to be, the wider the span of the test ball diameter can be.关键词
