Abstract

The invention belongs to the technical field such as gear fatigue test, and particularly relates to a threaded member fatigue test load loading device. The threaded member fatigue test load loading device comprises a base, an electromagnetic exciting device, a testing stand, an upper chuck, a lower chuck, a connecting rod and a crossbeam. The electromagnetic exciting device is arranged on the base. The testing stand is arranged above the electromagnetic exciting device. The lower chuck is fixed on the testing stand. The opening positions of the upper chuck and the lower chuck are respectivelyprovided with a threaded hole. Two ends of the threaded member are respectively fixed in the threaded hole of the upper chuck and the lower chuck. The upper chuck is connected with the crossbeam through the connecting rod.

Description

technical field [0001] The invention belongs to the technical field of gear fatigue tests and the like, and in particular relates to a load loading device for fatigue tests of screw parts. 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 component...
