Abstract

The invention relates to the field of mechanical test devices, and particularly relates to an impact load tester for pulleys. The impact load tester for pulleys comprises a first motor, a coupling, arotating shaft rod, eccentric wheels, pressing wheel assemblies, a second motor, a driving wheel assembly, a measurement assembly, and a tension spring guide post. The first motor is connected to therotating shaft rod through the coupling. The plurality of sets of eccentric wheels are fixed on the rotating shaft rod, and the pressing wheel assemblies are respectively arranged below the pluralityof sets of eccentric wheels and in contact with the eccentric wheels. The pressing wheel assemblies are elastically connected to the tension spring guide post through tension springs. The tension springs are used to reset the pressing wheel assemblies. According to the invention, synchronous test on a plurality of sets of pulleys is achieved by one device, and the impact load tester has high testefficiency and independent measurement assemblies for each pulley, thereby facilitating later maintenance.

Description

technical field [0001] The invention relates to the field of testing devices, in particular to a pulley impact load testing machine. Background technique [0002] Pulleys are often used in hoisting machinery. As an important part of hoisting machinery, there are strict requirements on the hardness and bearing capacity of the pulleys. Once the pulleys are damaged, it will cause potential safety hazards, such as the pulleys in elevators, and the service life of the pulleys. There are strict requirements. Therefore, a series of index tests will be carried out on the pulley before the pulley is put on the market. Among them, the impact load test of the pulley is one of the important indicators that the pulley needs to be tested in some special fields. At present, there is a pulley impact load test. One device can only perform the impact load test on one pulley, and cannot test multiple pulleys at the same time, and the test efficiency is low. SUMMARY OF THE INVENTION [0003...
