High load anti-friction plate testing machine

Abstract

The invention relates to a high-load antifriction plate testing machine, which comprises a frame-type pressure-bearing rack, wherein two symmetrical antifriction plate seats are arranged in the frame-type pressure-bearing rack; the opposite surfaces of the two antifriction plate seats are separately provided with a testing antifriction plate through lateral pressure type mechanisms; an opposite friction element which is positioned between the two antifriction plate seats and can carry out reciprocating motion back and forth in a horizontal direction is also arranged in the frame-type pressure-bearing rack; two side surfaces of the opposite friction element are separately in contact with the testing antifriction plate; a heating mechanism is arranged on the opposite friction element; the opposite friction element is connected with a translation driving mechanism; any one antifriction plate seat in the two antifriction plate seats is connected with a loading pressure maintaining mechanism. The high-load antifriction plate testing machine has the advantages that the high-load antifriction plate testing machine can simulate working state tests under various working conditions of the high-load antifriction plate.

Description

technical field [0001] The invention belongs to the technical field of testing machines, and relates to the test of anti-friction plates for nuclear reactor pressure vessel supports, in particular to a high-load anti-friction plate test machine. Background technique [0002] High-load anti-friction plates have a wide range of engineering applications, and some anti-friction plates are used in very harsh environments. Its structure is extremely important, and oil-free lubrication is generally required, and its important performance indicators need to be determined through simulation experiments. For example, the anti-friction plate of the domestic reactor pressure vessel support has a large bearing specific pressure and a high practical ambient temperature. It requires oil-free lubrication, guarantees a service life of 60 years, and can cope with geological disasters such as earthquakes. As a key component for supporting the reactor pressure vessel and reducing friction when...

Problems solved by technology

However, there are many problems in this kind of test equipment: first, it cannot reflect the high temperature wear state; second, due to the high specific pressure, there are often eccentric wear phenomena, which cannot reflect the real wear situation well, etc.

Moreover, there is no domestic testing machine specifically for the verification test of high-load anti-friction plates
