Description

technical field [0001] The invention relates to a rotary reciprocating friction and wear testing machine, which belongs to the technical field of friction and wear testing machines. Background technique [0002] The friction and wear testing machine in the prior art has the defect of single function, for example, the linear reciprocating friction and wear testing machine can only perform the test of reciprocating friction and wear, while the rotary friction and wear testing machine can only perform the test of rotating friction and wear. Due to the single function of the existing friction and wear testing machines, users often need to configure testing machines with different functions, resulting in a large waste of funds. Moreover, the linear reciprocating motor generally used in the linear reciprocating friction and wear testing machine in the prior art is often only applicable to the low frequency range or high frequency range, the applicable range is narrow, and it canno...

Problems solved by technology

[0004] In addition, the secondary problem to be solved by the present invention is: in various vertical loading force test equipment, the self-weight in the sensor measurement structure also needs to be measured, and the directions of self-gravity and loading force are opposite, and its measurement process in the prior art is very It is annoying to lock, so this part of the value is often removed by manual input, which affects the process of automatic collection and affects the measurement accuracy, so finding a new structure method can solve the above problems

[0005] Another secondary problem to be solved by the present invention is: in the friction and wear test of the reciprocating column tile, the contact between the upper and lower samples is a very important index, and the contact of the upper and lower sample friction surfaces is crucial to the frictional force. Important, it also affects the friction coefficient of the material, which also affects the accuracy of material judgment

In the existing friction and wear testing machine, there is a defect that the upper sample and the lower sample do not match well due to the uneven application of force in the friction pair of the column and the pad, which affects the test results

[0006] Another secondary problem to be solved by the present invention is: the friction test is an important indicator in the high temperature state of the material. In the prior art, the radiation heating method is used to meet the high temperature requirements, but the radiation heating has a great impact on peripheral devices. And the power consumption is large, the temperature cannot reach the high temperature requirement of about 1000 ℃, and its structure is relatively complicated
