Problems solved by technology

The disadvantage of this is that the active and driven three-jaw chucks will always have concentricity deviations (due to manufacturing, adjustment during clamping, wear, etc.), which will cause twisting forces on the hub axis.
Causes abnormal damage in hub wear test

Abstract

A wear-proof tester of front and back shafts on bicycle is prepared as setting external surface of two ends on erection cartridge in internal circle of two support bearings, fixing base of said bearing on support platform, fixing chain wheel on erection cartridge, setting the first and second fixing jacket and regulation washer actively in erection cartridge, arranging locking unit at another end of erection cartridge to press regulation washer and setting load unit on support platform under base of bearing.

Description

technical field [0001] The invention relates to a wear-resistant detector for front and rear wheel bearings of a bicycle. Background technique [0002] At present, there are mainly two types of hub wear testing machines in the market, J25A-00 represented by Tianjin Bicycle Research Institute and a certain type of testing machine represented by Taiwan Junyan Precision Machinery. The main design principles are as follows: [0003] 1. Tianjin Bicycle Research Institute J25A-00, the left and right axis of the hub is fixed, and the load is loaded on the hub tube through rolling bearings (four rolling bearings are pressed on the tube). The hub driving method is to use the rear hub to spin the flywheel and drive the sprocket The rotation drives the flywheel to rotate, so that the hub also rotates; the front hub connects the rotating shaft and the spoke holes of the faceplate through pins, and when the rotating shaft rotates, it drives the faceplate to rotate. The disadvantage of t...
