A gear fixture suitable for gear test bench

Abstract

The invention discloses a gear fixture suitable for a gear test bench, and relates to the technical field of gear testing. The invention includes a positioning platform; a chute is provided on one surface of the positioning platform; a small wheel bearing support and an intermediate wheel bearing support are connected by screws in the chute; two angular contact bearings are arranged inside the bearing support; the angular contact bearing support is small Wheel main shaft and intermediate wheel main shaft; the gear to be tested is fixed on the shaft; the gears to be tested are respectively covered by the casing to realize the sealing of the gear; there is a gasket under the positioning table. The invention adjusts the center height of the gear pair by adjusting the thickness of the gasket, so that the device can flexibly adjust the test height of the gear to be tested, thereby improving the versatility of the device. The two bearings inside the bearing support are separated by an inner spacer, which lengthens the support distance of the bearing support and reduces the radial runout at the end of the main shaft; the gap between the shell and the bearing support is sealed with rubber to allow the device Better sealing.

Description

technical field [0001] The invention relates to a gear fixture in gear testing. It belongs to the field of precision test and measurement technology, precision instruments and mechanical transmission. Background technique [0002] With the rapid development of the automobile industry, robot technology, and aerospace technology, the equipment has become large-scale, automated, and complex. Among various industrial equipment, the gear transmission system is the most widely used power and motion transmission device, and its operating status will directly affect the performance of the entire device. The failure and failure of the gear transmission system will cause huge losses to the entire production and society. Once the gears in the gear transmission system break down, it will affect production and cause economic losses, and cause casualties and tragedy. Therefore, gear testing, including transmission accuracy testing and life testing, plays an important role in the servic...

AI Technical Summary

Problems solved by technology

At present, there is no special fixture suitable for the gear test bench. The existing clamping method is to directly fix the gear on the gear test bench through a clamping device, which is difficult to clamp.

The clamping conditions are different each time, the measurement repeatability is relatively low, and the measurement results cannot accurately evaluate the gear transmission accuracy or life, etc.
