AI Technical Summary

Technical Problem

Existing double gear tooth-setting tooling suffers from high cost, high tooth-setting accuracy requirements, and inconvenient operation, especially during assembly and integrated machining, where efficient and accurate tooth-setting operations are difficult to achieve.

Method used

The system employs a combination structure of a positioning plate and a centering rod. Through the design of a worm gear rack and a slider, the center of the gear is quickly determined. The positioning device and wire exit device on the centering rod are used to achieve precise alignment of the tooth groove center line. Combined with the detachable design of the mounting rod, it can adapt to the tooth alignment requirements of different gear models.

Benefits of technology

It improves the accuracy and convenience of double gear tooth setting, reduces production costs, and enhances the applicability and tooth setting efficiency of tooling.

Abstract

The application relates to the technical field of gear pairing, in particular to a double gear pairing tool, which comprises a positioning disc and a centering rod, an inner cavity is formed in the positioning disc, a rotating disc is rotatably arranged in the inner cavity, and external teeth are formed in the rotating disc side wall; a worm-shaped rack is arranged on the rotating disc top surface, three sliding openings are formed in the positioning disc side wall, sliding blocks are horizontally slidably arranged in the sliding openings, and threaded grooves are arranged at the sliding block bottoms; a gear shaft is further rotatably arranged in the inner cavity, a driving gear is arranged on the gear shaft, the centering rod is rotatably connected to the rotating disc center, two positioning devices for clamping into gear tooth grooves are slidably arranged on the centering rod, and each positioning device comprises two coaxially arranged positioning parts. The double gear pairing tool can quickly determine the gear center, quickly find the center line of the gear tooth groove, and enable workers to more conveniently and intuitively perform gear pairing operation, thereby improving the gear pairing accuracy.
