Water lubrication rubber bearing performance test stand and test method thereof

Abstract

The invention discloses a water lubrication rubber bearing performance test stand and a test method thereof. The test stand consists of five portions. A driving portion comprises a variable-frequencymotor, a coupler, a driving shaft, a front supporting bearing and a rear supporting bearing which are successively connected with one another; a water lubrication rubber bearing portion comprises a water lubrication rubber bearing and an outer bearing sleeve, and the bearing sleeve is connected with an outer supporting framework by virtue of a three-shaft force sensor; a loading portion comprisesa supporting framework arranged on a guide rail, as well as a rocker bar mechanism and a shock excitation motor with an eccentric wheel which are connected with the supporting framework in sequence; acontrol test portion comprises a control cabinet, a sensor, a current collection ring, a data acquisition system and the like; and an auxiliary portion comprises a circulating water system, a sealingapparatus, a supporting seat and the like. The driving shaft rotates in the water lubrication rubber bearing, and the static or dynamic loading for the water lubrication rubber bearing can be realized by virtue of the loading system. The water lubrication rubber bearing performance test stand can be used for testing the performance of the water lubrication rubber bearing and is high in interference resistance.

Description

technical field [0001] The invention relates to the field of component detection and testing, in particular to a water-lubricated rubber bearing performance testing test bench and a testing method thereof. Background technique [0002] As a lubricant with bright prospects in the shipbuilding industry, water has many characteristics such as non-pollution, wide availability, stable performance, safe use, and flame retardancy, and has received high attention in the shipbuilding field. In order to minimize or reduce the wear, noise, impact and many other problems caused by the relative friction of the friction pair composed of metal components during the working process, but also to save the consumption and waste of limited resources such as lubricating oil and precious rare metals, especially In order to reduce the pollution of water resources in rivers, lakes and seas and protect the living environment of human beings, water-lubricated bearings have been widely used in the shi...

AI Technical Summary

Problems solved by technology

[0004] Through the summary and analysis of the research results of water-lubricated rubber bearing test benches at home and abroad, it is not difficult to find that the design of most test benches is only for a single slat of the rubber bearing, although some relevant performance data of a single slab of the bearing can be obtained in this way , but cannot be guaranteed to reflect the overall properties of rubber bearings

In a small number of test benches designed for the overall structure of rubber bearings, the collection and calculation methods of some key data are not accurate enough, which affects the entire test results
