The fatigue test electromagnetic excitation loading device comprises a base, a turbine box, an iron balance, an electromagnet and a test table, the turbine box is arranged on the base, the upper end of the turbine box is connected with the iron balance, the turbine box is used for adjusting the height of the iron balance, the electromagnet is arranged at the upper end of the iron balance, the test table is arranged above the electromagnet, a magnetic gap adjusting device is arranged between the test bed and the electromagnet, a ball screw rod and a stepping motor are arranged in the turbine box, the lower end of the ball screw rod is connected with the turbine box; the upper end of the ball screw rod is connected with the iron balance, and the stepping motor drives the ball screw rod to stretch and contract to adjust the height of theiron balance.

Description

technical field [0001] The invention belongs to the technical field of gear fatigue test and the like, and in particular relates to an electromagnetic excitation 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 com...
