[0003] Now to test the anti-friction and anti-wear performance of liquid and semi-solid lubricating materials, the general methods are four-ball machine method, Timken method, etc., all of which have the following shortcomings that are difficult to overcome: 1. The instruments and equipment used in the method are expensive, bulky, and cannot be carried ; 2. The method is cumbersome to operate, time-consuming and expensive; 3. The method is highly specialized and difficult for non-professionals to understand and accept; Practical needs for evaluation and comparison
[0012] First of all, the utility model testing machine is not accurate in evaluating the anti-friction and anti-wear performance of lubricating oil through wear marks. There is no accurate standard to judge the size of wear marks, and the wear marks themselves are also irregular. Different people The judgment of wear marks is also different, which will lead to personnel errors
[0013] Secondly, after each test, the friction pair needs to be replaced and repaired, which increases manpower, material and financial resources
[0014] Furthermore, the temperature is easily affected by the external environment, so that the accuracy of the measurement results is not high
[0015] Finally, the utility model cannot obtain the test results in the first time, and needs to calculate

Abstract
The invention relates to a friction testing machine for testing and evaluating friction reducing and antiwear properties. The friction testing machine comprises a motor-driven rotary friction wheel, a fixed friction wheel and a current measurement device, the rotary friction wheel soaked in a lubricant sample and the fixed friction wheel are in mutual sliding friction to generate frictional resistance which is displayed by a frictional resistance calculation and display unit in a current variation form, and the frictional resistance calculation and display unit connected with the current measurement device visually and qualitatively displays friction reducing and antiwear properties of lubricating oil test samples tested currently in a graphic mode. The friction testing machine of an integral structure is convenient to install, debug and use, lightweight and convenient to carry, and dost not require professional training or other precise instruments when performing field tests in different occasions. A testing method using the portable friction testing machine for testing lubricating oil, lubricating grease and anti-friction agent is simple, convenient to operate, high in accuracy and strong in practicality.
