Abstract

The invention provides an experiment table for testing the transmission efficiency, the instantaneous tooth surface temperature rise and the fatigue life of a high-speed transmission gear. According to the experiment table, an electric closing type closed loop system is adopted by a gear experiment table, gearboxes are connected in a back-to-back manner, and the power loss in the operation processes of the gearboxes is obtained by carrying out a contrast experiment on the two gearboxes. The experiment table comprises two three-phase asynchronous variable frequency motors suitable for high rotation speed and high power, two torque and rotation speed sensors, two temperature sensors, a tested gearbox, an accompanying type test gearbox, and a lubrication system. Aiming at the requirements, the invention provides the high-rotation-speed transmission gear experiment table approaching to engineering practices; and according to the high-rotation-speed transmission gear experiment table, high-rotation-speed working condition parameters and the instantaneous temperature rise at the surfaces of gear teeth can be simultaneously measured, and the instantaneous efficiency and the total meshing efficiency of the gearboxes in each working condition process can be simultaneously calculated, so that the intensive study can be carried out on the performances of the whole transmission gear.

Description

technical field [0001] The invention relates to a test bench for testing the efficiency, instantaneous temperature rise and fatigue life of a high-speed gearbox. More specifically, the present invention relates to tests including different flow rates of lubricating oil, the lubrication state of the gearbox under pressure, the transmission efficiency and the temperature rise at different positions on the tooth surface. Background technique [0002] With the development of the machinery industry and the continuous improvement of scientific research level, higher requirements have been put forward for the experiment and detection methods of mechanical transmission products. In the vehicle transmission system, even in high-speed and heavy-duty vehicles, the gearbox is one of the key components. Its working state and reliable life directly affect the overall performance of the entire transmission system, which in turn affects the stability, safety and reliability of the entire ve...
