磨齿机与滚齿机的分度蜗轮,如果齿距(相邻和累积)超差不多,又有可能修复,而且比较经济,或虽不经济但又无法弄到现成备件时,则应采取修复的方法解决。 分度蜗轮从其使用情况来看,在理论上应该是均匀的磨损,但由于蜗轮材料金相组织不均匀,硬度不一致,或其它偶然因素的影响,常会造 Grinding machines and hobbing machine indexing worm gear, if the pitch (adjacent and cumulative) is almost the same, it is possible to repair, and more economical, or though not economical but can not get ready-made spare parts, you should take the repair method solve. Indexing worm gear from the point of view of its use, in theory, should be uniform wear, but due to uneven microstructure of the worm wheel material, hardness inconsistencies, or other accidental factors, often make
