大部分汽车同步器中的滑动齿套都有防脱挡的倒锥齿。在加工倒锥齿时,多数厂家采用滚挤加工,这样就在花键的大、小径及齿侧产生金属堆积——毛刺,很难清除。 针对这种情况,我厂对通用的花键推刀进行了改进,用它推去滚挤过程中形成的毛刺,工件表面粗糙度值R_a1.6μm,配合精度在6级以上。用这 Most of the synchro sliding gear sets have anti-off the block inverted bevel gear. In the processing of inverted bevel gear, the majority of manufacturers use squeeze processing, so that spline in the large, small and tooth side metal accumulation - burr, it is difficult to remove. In response to this situation, I plant on the general spline push knife was improved, use it to push the burr formed in the rolling process, the workpiece surface roughness R_a1 .6μm, with the accuracy of 6 or more. Use this
