Description

technical field [0001] The invention relates to a wear test device, in particular to an axial piston pump swash plate-slider shoe friction pair wear test device and a test method thereof. Background technique [0002] Compared with traditional machinery, hydraulic machinery has a series of advantages, and it is widely used in construction machinery equipment. Axial piston pump is one of the components with the most complex structure in the hydraulic field and high requirements for technology and materials. In particular, the friction pair has more stringent requirements on the performance of the process materials. As one of the most important friction pairs, the swash plate-slider friction pair not only has complex motion states and dynamic characteristics, but also has a relatively high working environment. It is harsh, and its performance directly affects the working performance of the axial piston pump. With the continuous development of high-speed, high-pressure and hig...

Problems solved by technology

[0003] However, the experimental results of the swash plate-shoe friction pair wear test carried out at home and abroad are not ideal. The quality and pressure of the oil cannot be tested, which makes it impossible to study the working conditions of the swash plate-slipper friction pair under various working conditions

However, the wear test of the swash plate-slider friction pair is usually carried out by the durability test of the whole machine, which not only has a long cycle and is inefficient, but also requires a lot of manpower and material resources.
