在没有自动分齿机构的机床上,加工轴齿轮、人字齿轮、伞齿轮,花键和等分键槽等,一般都采用图1所示分度板,进行手摇分度。分度时,分一个齿需要摇几转、几十转;有的可能要摇几十转零几个孔。这样,操作者稍不注意,就会数错,多摇或少摇转数或孔数,造成废品。我厂谢宗林同志设计的行星式 In the absence of automatic sub-gear mechanism on the machine, processing shaft gear, herringbone gears, bevel gear, spline and equal keyway, etc., are generally used in Figure 1 indexing board, manual indexing. Indexing, a few teeth need to shake a few revolutions, dozens of turn; some may want to shake a few dozen a few holes. In this way, the operator a little attention, it will be the wrong number, shake or shake less or the number of holes, resulting in waste. Planetary design of our factory, Comrade Xie Zonglin
