A processing method for face-to-face modification of worm gear tooth surface

Abstract

The invention relates to a straight-face modification processing method for the tooth surface of a worm gear, which is used for milling the tooth surface of the 1 / 2 tooth width of the worm wheel according to the height of the index circle, including 1) according to the height of the index circle of the worm wheel after tooth milling Tooth shape processing finger milling cutter; 2) Place the milled worm gear workpiece flat on the gear hobbing machine workbench, and align it; 3) Perform tool alignment according to the tooth surface at the indexing circle, and adjust the differential mechanism according to the rising angle of the worm Carry out processing, processing to 1 / 2 tooth width; 4) After processing one tooth surface, process the next tooth surface in an index; 5) Process several tooth surfaces according to the assembly requirements, all processing is completed, and oiled after passing the inspection , storage. Compared with the prior art, the beneficial effects of the present invention are: 1) It solves the requirement of face-to-face modification of the tooth surface of the worm gear, and realizes the purpose of putting the worm gear and worm into the box for assembly at the same time; 2) The processing process is simple, and the production The process is easy to control, and the product quality meets the requirements; 3) The indexing function of the gear hobbing machine is fully utilized, and the processing accuracy is high.

Description

technical field [0001] The invention relates to a tooth surface processing method, in particular to a worm wheel tooth surface straight-face modification processing method. Background technique [0002] Due to the large meshing friction of the worm drive, the difficulty of accurately shoveling the back of the worm gear hob, and the error in shape and size, it is difficult for the machined worm gear tooth surface to completely reach the conjugate state that meets the theoretical requirements with the matching worm tooth surface. When it cannot be adjusted to the best state, it is easy to cause the worm gear transmission to fail. [0003] The assembly process of the worm gear reducer is: fix the bearings at both ends of the worm gear and install the oil seal; put the worm gear into the lower box to adjust the position, cover the upper box and fix it; put the worm into the worm hole, install the worm bearing and the oil seal ; Compress the end cover of the worm wheel and seal ...

AI Technical Summary

Problems solved by technology

It can be seen that, restricted by the structure of the worm gear and worm transmission pair, it is impossible to put the worm gear and the worm into the box at the same time when assembling the worm gear reducer to visually check the transmission situation and make appropriate adjustments. If the transmission fails after assembly, it needs to be disassembled and reinstalled. It's very troublesome

[0004] At present, a new worm gear assembly method has emerged, which flattens half the tooth width of several tooth surfaces of the worm gear, so that the worm gear can be assembled in the box at the same time, but when it comes to the processing of tooth surface modification There is a certain degree of difficulty in the problem
