齿轮式金刚石修整轮在外啮合珩齿新工艺中的应用

外啮合珩齿工艺是一种效率高、成本低的硬齿面齿轮加工工艺，但对齿轮精度的提高有限。本文采用自制的金刚石修整滚轮在Y4632A外啮合珩齿机上对外啮合珩磨轮进行修形，明显提高了外啮合珩齿的加工精度，使外啮合珩齿有可能应用于硬齿面齿轮精加工。在此基础上，进一步提出了用金刚石修整轮代替珩磨轮直接珩齿的新工艺，试验证明，新工艺省去了珩磨轮的制作和修形过程，进～步提高了加工效率和加工精度，操作容易，加工成本不高，直接使用外啮合珩齿机，相对于设备价格昂贵的内啮合珩齿机和磨齿机，节约了大量设备投资，适于中小企业生产，是一种切实可行的硬齿面齿轮精加工方法。

Application of Diamond Dressing Gear in Gear Honing

Honing with a honing gear is an efficient and low - cost method for hard gear machining, but it can not obviously improve the precision of gear. In this paper, The author used a selfmade diamond dressing gear to profile the honing gear in Y4632A external honing machine, resulting in an obvious improvement of the precision of the machined gear. It is shown that a honing gear can be used for hard gear finish machining by this profiling method. Further more, the author puts forward a new gear honing method; Instead of an ordinary honing gear, a diamond dressing gear is used to hone the gear. Machining efficiency is improved, and the profiling process is saved. Experiment shows that the precision of gear are more improved. Contrasted to using expensive internal honing machine, the method saves a lot of money by using cheap external honing machine. The method is suitable for small scale production, and is feasible for hard gear finishing .
