Worm wheel gear tooth axial center measuring device and measuring method thereof

Abstract

The invention discloses a worm wheel gear tooth axial center measuring device and a measuring method thereof. The device comprises a bracket, a sliding mechanism, a clamping mechanism, a distance measuring device and a dial indicator. The sliding mechanism and the clamping mechanism are arranged on the upper end and the lower end of the bracket respectively. The distance measuring device and the dial indicator are arranged on the sliding mechanism, and are driven by the sliding mechanism. The distance measuring device measures the worm wheel gear slot bottom axial median position value. The midpoint of a worm wheel gear bottom slot is searched by the dial indicator, so as to measure the deviation of the axial median position of a worm wheel gear. According to the invention, the median position error condition or deviation condition of a number of gear teeth of a worm wheel can be directly quantified and read; a defective worm wheel is quickly removed to eliminate the hidden danger of quality control; the median position deviation value of a qualified worm wheel is quickly provided; the assembling process efficiency is improved; the combination cost is reduced; and the device has the advantages of small and exquisite tools, easy operation and no field restrictions, and is portable and maintenance-free.

Description

technical field [0001] The invention relates to a centering device for worm gears and a measuring method thereof. Background technique [0002] In the assembly process of traditional military and civilian worm gear attached transmissions, due to the lack of means to quantify the center position of the worm gear teeth, the diameter of the worm gear is entered, and the axial direction of the worm gear is used to increase or decrease the shims in stages to distinguish whether the worm gear and the worm are centered (the center line coincides) , whether the contact area is symmetrical or not. In traditional assembly, this process is mainly based on estimation and adjustment, which cannot be accurately quantified. In addition, if the coherence and linearity of the worm gear’s multi-tooth median cannot be quantified, the position of the meshing plaque will appear suddenly left and suddenly Right and other irregular states, which will cause the assembly process to fall into a stand...

Problems solved by technology

[0002]In the assembly process of traditional military and civilian worm gear transmissions, due to the lack of means to quantify the median position of the worm gear teeth, the diameter of the worm gear is entered, and the worm gear axis is gradually increased or decreased Gaskets are used to identify whether the worm gear and worm are centered (the center line coincides), and whether the contact area is symmetrical. This process is mainly based on estimation and adjustment in traditional assembly, which cannot be accurately quantified. The coherent linearity of the position is not good, and there will be irregular states such as the position of the meshing plaque from left to right, which will cause the assembly process to fall into a pause in troubleshooting, and even cause unqualified worm gears to enter the assembly, resulting in unnecessary troubleshooting and disassembly during the process. And it brings hidden dangers to the product; secondly, if the median value of the gear teeth cannot be quantified in advance, it will be assembled gradually based on actual experience, resulting in multiple measurements and disassembly during the process, which is inefficient. The assembly fit data of the still cannot be accurately quantified

In the assembly of the above-mentioned reducer, the technical conditions have the requirements for the centering of the gear teeth and the contact area of ​​the worm gear. Assuming that the worm gear has a good tooth shape, if the quantitative control of the worm gear can not be guaranteed once before assembly, then It is unavoidable to smear and clean the red lead powder multiple times, as well as related disassembly and assembly, which will lead to the labor cost, time cost, cleaning agent cost and red lead pollution in the process, especially the cost of mass production will increase several times.
