Description

technical field [0001] The invention belongs to the technical field of gear fatigue test and the like, and in particular relates to a dynamic load loading device for fatigue test. Background technique [0002] With the development of the machinery industry and the continuous improvement of scientific research levels, higher requirements have been put forward for the experiments and testing methods of mechanical products. [0003] In gear design, especially for gears with high reliability requirements, the results of evaluating the safety factor based on reliability theory can hardly reflect the reliability level of gears at all. Therefore, it is usually necessary to carry out fatigue tests on gears to check the reliability and durability of gears, esp. [0004] The fatigue test of gears, metal materials and their components needs to test and detect the fatigue characteristics, fracture mechanics, crack growth rate, etc. of gears, metal materials and their components under t...
