[0020] Example 2:

[0021] The device of the present invention can not only measure the friction behavior of the sample during reciprocating motion, but also can measure the friction behavior of the sample during rotation, such as image 3 As shown, the reciprocating mechanism is replaced with a rotating mechanism. The rotating mechanism includes a sample stage 3 and a sample stage base 7. The sample stage 3 is placed on the sample stage base 7, the sample stage base 7 is fixed on the operating table 11, and the sample stage base 7 There is a rotary output shaft arranged in the vertical direction on the upper part of the rotary output shaft. One end of the rotary output shaft is connected to the sample stage base 7, and the other end is connected to the driving motor power, so that the motor drives the sample stage 3 to rotate to realize the friction behavior measurement during the rotation movement. The other parts of the inventive device are the same as the first embodiment.

Abstract

The invention discloses a pneumatic loading type frictional wear tester which comprises a sample stage, a loading mechanism, a drive mechanism, a data acquisition unit and a stander; the sample stage is arranged on the stander and can do rotary motion or alternate motion under the driving of the drive mechanism; the loading mechanism comprises a head support, a friction head, a cylinder; the friction head is arranged on the head support. The head support is connected with the cylinder and can cause that the friction head on the head support closely pressures or breaks away the surface of the sample arranged on the sample stage. The data acquisition unit gathers the pressure applied on the sample by the friction head and the frictional data. The cylinder adjusts the pressure applied on the sample by the friction head according to the information fedback by the data acquisition; in the pneumatic loading type frictional wear tester, the sensor gathers the pressure information, and a computer controls an electric reducing valve to regulate the throughput of the cylinder; the regulation range of the pressure is wider; the pneumatic loading type frictional wear tester can effectively evaluate the frictional wear performance of a running pair with different materials and technique.

Description

technical field [0001] The invention relates to a pneumatic loading type friction and wear testing machine. Background technique [0002] Existing friction and wear testing machines mainly include hydraulic loading friction and wear testing machines, servo system testing machines, and weight loading testing machines. The hydraulic loading method is used for large load loading, and its test range is narrow and its adaptability is poor. The equipment of the servo system testing machine is relatively expensive, which increases the cost of the friction test. In the weight-loaded testing machine, the loading load is fixed during the friction and wear test, and it is impossible to adjust the loading load at any time during the friction and wear test. In addition, the weight-type loading requires manual replacement of weights to adjust the loading load , the test efficiency is very low, and special personnel are required, which increases the cost of the test. Contents of the inv...
