Abstract

A high temperature testing machine for gears comprises a gear transmission case used for testing the fatigue life of the gears, wherein the gears to be tested are installed in the gear transmission case, the gear transmission case is connected with a temperature control system, the temperature control system comprises a heating device and a control module of a temperature monitor device, the heating device is connected with the gear transmission case through a pipeline, the heating device conveys lubricating oil into the gear transmission case through the pipeline to heat and lubricate the gears to be tested in an oil bath mode so that the working condition of gears inside an aviation speed reducer can be simulated, and the lubricating oil is heated to reach the set temperature. The temperature monitor device is installed on the heating device to monitor the temperature of the lubricating oil in real time, temperature information is fed back to the control module, and then the heating temperature can be monitored and controlled. Long-time simulation testing under the high temperature can be carried out on the gears, the testing temperature is high, working time is long, the testing environment is more approximate to the actual working condition of the aviation gears, and testing results are more effective and credible.

Description

technical field [0001] The invention relates to a testing device for simulating high-temperature working conditions of aviation gears, in particular to a high-temperature gear testing machine capable of precisely controlling the testing temperature. Background technique [0002] Aviation reducer gear is a key part working in complex environment. Temperature has a direct or indirect effect on various mechanical and mechanical properties of gears, such as fatigue properties, red hardness, friction and wear properties of materials, etc. With the continuous improvement of aircraft engine performance, the engine thrust-to-weight ratio continues to increase, and the working conditions of aero-engine reducer gears are becoming more and more stringent. The highest meshing surface temperature of the gears has reached 623K. The improvement. [0003] The actual temperature of the gear is formed by superimposing the body temperature and the instantaneous flash temperature. The factor...
