Description

technical field [0001] The invention belongs to the field of aerospace transmission and lubrication, and relates to an aviation spline vibration lubrication wear tester. technical background [0002] The spline coupling has simple structure, high reliability, high transmission power per unit weight, simple lubrication and maintenance, and is an inevitable choice for aerospace transmission connections. [0003] However, the misalignment of the spline, the vibration and wear of the residual dynamic balance under the cantilever moment, the grease lubrication problem at high temperature, etc., together lead to the spline not reaching the expected service life. [0004] The vibration and wear of the spline is a slow-changing process, and the position of the spline is typically inaccessible. It is difficult to maintain and maintain it, and it is also difficult to monitor and repair it in actual operation, and it is even difficult to accurately understand its wear. Therefore, it is...

[0003] However, the misalignment of the spline, the vibration and wear of the residual dynamic balance under the cantilever moment, the grease lubrication problem at high temperature, etc., together lead to the spline not reaching the expected service life

[0004] The vibration and wear of the spline is a slow-changing process, and the position of the spline is typically inaccessible. It is difficult to maintain and maintain it, and it is also difficult to monitor and repair it in actual operation, and it is even difficult to accurately understand its wear. Therefore, it is necessary to Realize the simulation and prediction of spline lubrication and wear through a suitable spline lubrication and wear tester
