AI Technical Summary

Technical Problem

Traditional friction and wear testing devices suffer from uneven pressure due to loose clamps during the friction process, which affects the accuracy of the test results.

Method used

A friction and wear testing device with an adjustable pressure mechanism is used. Through the cooperation of counterweight, lever assembly and push rod, the contact pressure between the friction component and the test component is adjusted in real time to ensure a stable contact state during the friction process.

Benefits of technology

This improves the accuracy of friction and wear testing, ensures there is no gap between the friction component and the test component during each friction test, and enhances the reliability of the test results.

Abstract

A friction and wear testing device with a pressure adjusting mechanism, comprising a frame, a testing assembly, a driving mechanism, and a pressure adjusting mechanism. The testing assembly comprises a testing base and a friction rod. The pressure adjusting mechanism comprises an adjustable weight assembly, a lever assembly connected with the adjustable weight assembly, and a abutting assembly connected with the lever assembly. The abutting assembly comprises an abutting rod. The adjustable weight assembly comprises a weight carrier and a plurality of weight carrier blocks. The adjustable weight assembly can freely adjust the gravity by increasing or decreasing the number of the weight carrier, and the gravity loading is amplified by the lever assembly to the abutting assembly to form an abutting force, which abuts against the testing base. The workpiece to be tested is abutted by the abutting rod between the testing base and the friction rod at all times, so that the product is always closely connected with the friction rod.
