一、主要用途本试验机主要用来研究金属材料在滚动摩擦、滑动和滚动复合摩擦情况下的磨损和有润滑油条件下出现的麻点和剥落。由于一对齿轮啮合的接触状况与一对滚子接触很相似(线接触),在齿廓上某一点的曲率半径就相当于圆柱滚子的半径,所以它可以模拟齿轮传动进行齿轮齿面接触疲劳强度的试验研究工作。二、结构及特点图1、2、3为试验机的外观,加载机构和传动示意图。
First, the main purpose The test machine is mainly used to study metal materials in the rolling friction, sliding and rolling under the friction wear and lubricants conditions occur under the pitting and peeling. Since the meshing engagement of a pair of gears is very similar to the contact of a pair of rollers (line contact), the radius of curvature at a point on the tooth profile is equivalent to the radius of the cylindrical roller so it can simulate gear transmission for gear tooth surface contact Experimental study of fatigue strength. Second, the structure and characteristics Figure 1,2,3 for the appearance of the testing machine, loading mechanism and transmission diagram.
