我厂生产汽车行星齿轮和半轴齿轮。行星齿轮的大端为球面,要求表面粗糙度Ra0.4,在通用磨床上难以加工。为此,我们自制了行星齿轮球面磨削机构,安装在通用磨床的工作台上。经多年的实践证明,工件磨削合格率达98％以上,深受操作者的好评。工作原理:行星齿轮球面磨削机构见图示。本机构是利用x轴转动,y轴摆动来实现球面轨迹的。它可安装在各种磨床上, I plant production of planetary gear and axle gear. The large end of the planetary gear is spherical, requiring surface roughness Ra0.4, difficult to process in a universal grinder. To this end, we made a planetary gear grinding mechanism, mounted on a universal grinder table. After many years of practice proved that the workpiece grinding pass rate of 98% or more, by the operator’s praise. How it works: planetary gear grinding mechanism shown. The agency is the use of x-axis rotation, y-axis swing to achieve the spherical trajectory. It can be installed on a variety of grinding machines,
