Problems solved by technology

The tooth shape of the processed gear is constantly changing and eventually exceeds the scope of the processing permit. At this time, if the original honing wheel is continued to be used for processing, the processing requirements cannot be met. To process qualified products that meet the requirements, a new internal tooth honing wheel must be replaced. , the cost of gear honing processing increases, which is not conducive to the promotion and use of this technology

Abstract

The invention relates to a honing wheel grinding method applied to the powerful honing teeth of the numerical control inner gear honing wheel. The application object is an inner tooth honing wheel, and the application machine tool is a numerical control inner tooth honing wheel strong honing machine. The operation steps of the grinding are as follows that 1, other parameters are calculated by thebasic parameters of the machined gear and the inner tooth honing wheel, according to the meshing principle of the conjugate tooth surfaces, and a conjugate meshing equation of the machined gear and the inner tooth honing wheel is deduced; 2, determining a point p on the tooth surface of the machined gear, and the original conjugate meshing equation is modified into an equation which takes the grinding amount and the axial intersection angle as variables according to the position parameters of the p point; 3, the accumulated grinding amount delta a corresponding to the grinding and grinding ofthe inner tooth honing wheel is calculated, and the corrected meshing equation is substituted into the modified meshing equation to obtain an axis angle correction value sigma and is applied to honingwheel grinding. According to the honing wheel grinding method applied to the powerful honing teeth of the numerical control inner gear honing wheel, the contact stability of the machined gear beforeand after grinding and the inner tooth honing wheel is guaranteed by introducing the shaft angle correction value, so that the grinding margin of the honing wheel can be fully utilized, and the machining quality of the machined workpiece is stable.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing technology, and in particular relates to a honing wheel grinding method applied to a numerically controlled internal gear honing wheel for powerful honing. Background technique [0002] CNC internal tooth honing wheel power honing is an efficient generative gear finishing method. The tool internal tooth honing wheel is similar to an internal tooth helical gear. It is composed of abrasive grains and bonding agent and belongs to a kind of grinding wheel. After a period of processing, the wear and tear of the abrasive grains of the internal gear honing wheel and the clogging of the honing wheel surface will cause problems such as an increase in the processing honing force and a sharp increase in honing heat. The error correction ability of the honing wheel is weakened and eventually the processed Decrease in gear quality. Under normal circumstances, in order to restore the normal proce...
