Problems solved by technology

[0005] When dynamic loads are applied to gears, metal materials and their components, the loading frequency is usually fixed, and the loading frequency cannot be adjusted, so it is impossible to conduct experiments on gears, metal materials and their components under different load loading frequencies and detection

Abstract

The invention belongs to the technical field of a fatigue test of a gear and the like, and particularly relates to a dynamic load loading device with a frequency modulation function. The dynamic loadloading device with a frequency modulation function comprises a base, a turbine box, a balance iron, an electromagnet, frequency modulation weights for regulating a resonant frequency, a test stand, afixture, a connection rod and a beam; the turbine box is arranged on the base; the upper end of the turbine box is connected with the balance iron; the turbine box is used for regulating a height ofthe balance iron; the electromagnet is arranged at the upper end of the balance iron; the test stand is arranged above the electromagnet; the frequency modulation weights are symmetrically arranged atboth sides of the electromagnet; the frequency modulation weights are connected onto a main screw rod between the test stand and the electromagnet by big bow springs; an excitation system is formed by the frequency modulation weights and the big bow springs; and a loading frequency is changed by changing the number of the frequency modulation weights.

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 with frequency modulation function. 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 ...
