回转减速机有异响的判别方法 从异响产生的原因看,回转减速机异响可分为两大类:一是由于轴承配合异常、齿轮啮合异常产生的响声;二是由于零件之间连接松动、零件损坏产生响声,此种异响多属零件间异常的摩擦与碰撞,故响声比较清晰。
齿轮啮合异常是指啮合间隙过小或过大、啮合部位不正确、啮合面积不足,此时会产生连续的清晰的响声,且也随转速的增加而响声增大;轴承配合异常是指轴承间隙过大或过小,当间隙过大时会产生连续的响声,并随车速的增高而增大。
1、轴承磨损或齿轮间隙失常 。其表现为:
汽车在行驶中,如车速越高响声越大,而滑行时响声减小或消失。
2、主动锥齿轮突缘紧固螺母松旷。其表现为:
在踏下加速踏板时汽车行驶正常,在放松加速踏板的过程中发出“呜”的响声,而匀速行驶时此响声消失。
