用经过热处理的高强度钢制造的齿轮,其传递的载荷和寿命可增加几倍。但因热处理使齿轮的节圆变成椭圆形,使传动的运动精度降低。热处理后,对齿轮的配合孔和端面进行磨削,就可使孔轴线与节圆的相对位置正确得多,从而保证了齿轮的运动精度。最合理的装卡方法是把齿轮以齿廓为基准安装在滚柱上。为保证齿轮最小的跳动,就要研究滚柱数量的合理选择及其沿齿轮圆周的布置。文中提出对圆柱齿轮解决此任务的一般方法。按提出的方法制造齿轮,运动误差最小.
With heat-treated high strength steel gear, the load and life can be increased by several times. However, due to heat treatment, the pitch circle of the gear becomes an oval shape, which reduces the motion accuracy of the transmission. After the heat treatment, grinding the mating holes and the end faces of the gears can make the relative positions of the axes of the holes and the pitch circles much more correct, thereby ensuring the precision of the movement of the gears. The most reasonable method of loading the gear is to gear on the basis of the profile mounted on the roller. In order to ensure the minimum beating of the gear, it is necessary to study the reasonable choice of the number of rollers and the arrangement along the circumference of the gear. The paper presents a general method of solving this task for a cylindrical gear. According to the proposed method of manufacturing gear, the smallest movement error.
