汽油机凸轮轴的齿轮,加工要求是节圆直径42.334毫米,齿斜角60°±30＇,啮合角14°30＇。过去径向进给靠手动,间断进给15次左右,长期以来生产质量不够稳定,劳动强度大,为此,我们对Y38滚齿机进行了改装。一、设计要求及工作原理 1.全齿高为4.6毫来。动作要求:快进、一工进、二工进、光刀、快退、复位。 2.工作台退出:工作时,工作台退出10毫来。换刀时,工作台退出250毫米。
Gasoline camshaft gear, processing requirements are pitch diameter 42.334 mm, tooth bevel angle of 60 ° ± 30 ’, the engagement angle of 14 ° 30’. In the past radial feed by manual, intermittent feed about 15 times, the quality of production for a long time not stable enough, labor-intensive, therefore, we Y38 hobbing machine was modified. First, the design requirements and working principle 1. The whole tooth height is 4.6 milliseconds. Action requirements: fast forward, a work, two workers into the light knife, rewind, reset. 2. Workbench exit: work, work bench exit 10 milli. Tool change, work bench exit 250 mm.
