Fretting Wear Resistance Tester
I. Introduction:
Lubricating Grease Fretting Wear Resistance Tester is used to evaluate the anti-fretting wear characteristics of grease when the bearing swings. Under the specified test conditions, it can distinguish the low, medium and high anti-fretting wear ability of different greases. This test has been applied to predict the anti-fretting performance of automotive wheel bearing greases in long-distance transportation. The test principle is to swing two sets of thrust ball bearings with test grease at an amplitude of 0.21, a swing frequency of 30HZ, a load of 2450N, and room temperature, and the test time is 22 hours. The average value of the sum of the mass loss of the two sets of bearing races is used as the evaluation of the anti-fretting wear performance of the test grease.
II. Main Features
1.This fretting wear tester adopts two sets of standard thrust ball test bearings, with an inner diameter of 16mm ± 0.025mm and an outer diameter of 35.69 ± 0.025mm;
2.Control the motor with a frequency converter to improve control frequency accuracy and display the operating frequency digitally;
3.Oscillating bearing seat with fixing screws;
4.The fretting wear tester is provided with a set of standard fixtures;
5.Digital display time controller,beep prompt when test time is reached;
6.High precision spring guide cylinder, length 31.75mm ± 0.25mm, outer diameter 23.02mm ± 0.05mm, inner diameter 13.614mm ± 0.013mm;
