一、概述齿輪滾刀的檢查,一般都使用万能工具显微鏡。但由于用光学投影的原理进行檢查,目測的誤差較大,尤其对螺旋角大的滾刀和蝸輪滾刀更甚,所以許多国家都在发展专門檢查仪。这些檢查仪的檢查方法大致有两种:(1)沿螺旋綫檢查;(2)沿啮合綫檢查。后者是最合理的方法,它的理論根据如下: 滾刀加工齿輪时,其刃口在切削过程中与工件齿形相切于一点(如图1),在这一点上切出工件理論齿 First, an overview Gear hob inspection, generally use the universal tool microscope. However, due to the principle of optical projection inspection, the visual error is larger, especially for spiral hob hob and worm hob even more so many countries are developing specialized inspection instrument. There are two ways to check these checkouts: (1) Check the helix; (2) Check the mesh line. The latter is the most reasonable method, its theory is based on the following: Hob gear, the cutting edge in the cutting process and the workpiece tangent at a point (Figure 1), at this point cut the workpiece theoretical teeth
