切制齿部带凸台工件的直齿插齿刀的设计计算与一般直齿插齿刀相同,今仅就其与一般插齿刀的不同点略述如下。这种插齿刀的齿数Z_0必须根据工件齿数Z_1及凸台个数按下述原则确定: 1.对于凸台均匀分布的工件,Z_0=K/nZ_1(K为从1到n的自然数)。K取多大为宜,需由Z_0的其他因素确定(例如不能使工件产生干涉及过大的顶切、根切、刀顶不能太尖等)。在Z_0确定后,插齿
The design and calculation of straight-tooth gear shaper with toothed workpiece with boss is the same as the general straight-gear gear shaper, and the difference between it and general shaper is as follows. The number of teeth of this gear shaper Z_0 must be determined according to the following principle according to the number of teeth Z_1 and the number of bosses: 1. For a workpiece evenly distributed on the bosses, Z_0 = K / nZ_1 (K is a natural number from 1 to n). K take more appropriate, need to be determined by other factors Z_0 (for example, can not interfere with the workpiece and the overcutting, cutting, the knife can not be too sharp, etc.). After Z_0 is determined, the gear is inserted
