国产圆弧齿圆柱蜗杆传动减速器,在承载能力和传动效率方面不及国外同规格产品。其原因除几何参数和材质的选取外,加工精度是重要因素。当前我国一些主要厂家,在磨削轴向圆弧齿蜗杆齿面时,采用轴向齿廓样板检查工件而来修整砂轮。铲磨滚刀也是如此。这对于多头蜗杆蜗轮将产生较大的齿形和分度误差,导致装配时接触精度较低,造成非共轭接触,常须通过加载或 Domestic arc-shaped cylindrical worm drive reducer, the carrying capacity and transmission efficiency less than the same specifications with foreign products. The reason for the addition of geometric parameters and material selection, the processing accuracy is an important factor. At present, some major manufacturers in our country grind the tooth surface of the axial arc tooth worm gear and adopt the axial profile model to check the work piece to trim the grinding wheel. Shovel hob as well. This will have a large worm gear worm and indexing error, resulting in the assembly of contact with low accuracy, resulting in non-conjugate contact, often by loading or
