A rolling wheel life testing machine

Abstract

The invention discloses a rolling wheel life testing machine, which comprises a frame and a plurality of loading levers placed side by side at intervals above the frame, one end of each loading lever is hinged on the frame, and the other end of each loading lever is hung with a counterweight The code is supported and lifted by an electronically controlled load adjustment mechanism. Drive wheels are respectively provided under each loading lever on the frame, and a supporting shaft assembly for supporting the test roller is provided in the middle of each loading lever. The roller to be tested passes through the support The shaft assembly is supported and fixed at the lower end of the loading lever. The loading lever is adjusted to a horizontal state and the roller to be tested is in contact with the driving wheel located below. The other end of the loading lever is equipped with a weight to press the loading lever downward. The adjustment mechanism is used to lift or lower the loading lever to realize the loading or unloading of the roller, and the electronically controlled load adjustment mechanism adopts automatic control to adjust the test load of the roller accurately and flexibly.

Description

technical field [0001] The invention relates to mechanical parts life testing equipment, in particular to a rolling wheel life testing machine. Background technique [0002] At present, many mechanical devices need to install rollers, which can be used as a link in the transmission system or for other purposes. The rotation performance of these rollers in mechanical equipment is often directly related to the transmission efficiency and stability of the transmission system, etc. or has other effects on the performance of mechanical equipment. Therefore, these rollers need to be tested for their mechanical properties and life parameters before leaving the factory. carry out testing. [0003] However, in the existing equipment for testing the life of rollers, the way of loading or unloading the load is relatively extensive, and the loading or unloading of the load is manually controlled, which has a low degree of automation and low work efficiency; It is a multi-station simu...

Problems solved by technology

[0003] However, in the existing equipment for testing the life of rollers, the way of loading or unloading the load is relatively extensive, and the loading or unloading of the load is manually controlled, which has a low degree of automation and low work efficiency; It is a multi-station simultaneous test. During the test, it is often necessary to manually monitor it to prevent damage to the roller being tested at a certain station. When the roller at a certain station is damaged during the test, the equipment must be shut down and taken out. Otherwise, if the equipment continues to perform load tests on other stations, the rollers on other stations will also be damaged due to long-term pressing, which will affect the test
