应用插齿机加工外啮合与内啮合的斜齿圆柱齿轮时,除了必需用斜齿插齿刀以外,螺旋导轨是关键部件。由于其型面复杂,精度高,给设计和制造带来不少困难。据了解,从国外进口一付中等尺寸的螺旋导套,就需上万美元的外汇和一年多的时间,而且只能配用于相应的进口插齿机。 我厂在试制 Application of gear shaper machining external and internal helical gear, in addition to the need to use helical gear shaper outside, the spiral rail is a key component. Due to its complex surface shape, high precision, to design and manufacture to bring a lot of difficulties. It is understood that imports from abroad a pair of medium-sized spiral guide sleeve, you need tens of thousands of dollars in foreign exchange and more than a year’s time, and can only be used for the corresponding imported gear shaper.
