Description

technical field [0001] The invention relates to a transmission gear contact spot test device. Background technique [0002] Hypoid gears are widely used in aviation industry, automobile industry and heavy mining equipment and other fields due to their large smooth running range, low sliding speed and high transmission efficiency. Especially with the rapid development of the automobile industry, the meshing quality requirements of the hypoid gears are getting higher and higher. In the field of automotive transmission technology, the gear tooth geometric parameters of all gear pairs are evaluated to see whether the contact spots are evenly and reasonably distributed, so as to optimize the NVH problems such as vibration and noise of the transmission. [0003] Tooth surface contact spots are one of the important indicators to measure the meshing quality of hypoid gears. The traditional detection of tooth surface contact spots is mainly based on visual judgment by experienced en...

Problems solved by technology

However, the preliminary work of the current tooth surface contact spot detection experiment and the power supply during the experiment are usually done manually, that is, the transmission is driven by manual hand cranking. The existing problems are that the test process is time-consuming, inefficient, and input And the control of the output torque depends too much on the experience of skilled operators, often with low precision and poor stability, resulting in large differences and fluctuations between the experimental results and expected data
