Constant velocity universal joint static torsion-like testing machine

Abstract

The invention provides a constant velocity universal joint similar static torsion testing machine which comprises a base, a rotary loading device and a test angle adjusting device, the rotary loading device and the test angle adjusting device are arranged on the base, and an accompanying test shaft parallel to a test shaft is arranged between the test angle adjusting device and the rotary loading device. The rotation loading device comprises a torque loading device, a rotation driving device and a first transmission gear box, the test angle adjusting device is provided with a second transmission gear box, and one end of the accompanying test shaft is connected with one end of the test shaft through the first transmission gear box. The other end of the accompanying test shaft is connected with the other end of the test shaft through the second transmission gear box, the torque loading device is connected with the accompanying test shaft and applies torque to the accompanying test shaft, the rotation driving device is connected with the accompanying test shaft and drives the accompanying test shaft to rotate, and the first transmission gear box and the second transmission gear box are reduction gear boxes. And the torque borne by the accompanying test shaft is smaller than that borne by the test shaft. And the equipment power consumption and the equipment maintenance cost are effectively reduced.

Description

technical field [0001] The invention relates to a quasi-static torsion testing machine, in particular to a quasi-static torsion testing machine for constant velocity universal joints. Background technique [0002] Constant velocity drive shaft quasi-static torsion testing machine is a special testing equipment for static torsion strength test of constant velocity drive shaft in the rotating state, and it is a special equipment for low-speed dynamic high-torque characteristic test of constant velocity universal joint assembly . [0003] The current quasi-static torsion test equipment has the following problems: torque loading and rotation are not synchronized, there is no reference comparison, equipment power consumption and equipment maintenance costs are high, so it is necessary to improve the above problems. Contents of the invention [0004] In view of the fact that the torque loading and rotation of the current quasi-static torsion testing machine cannot be completed ...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that the torque loading and rotation of the current quasi-static torsion testing machine cannot be completed synchronously, there is no reference comparison, and the equipment power consumption and equipment maintenance costs are relatively high. The present invention provides a constant velocity universal joint quasi-static torsion testing machine, which can Achieve torque loading and rotation drive at the same time, there is a synchronous comparison test, effectively reducing equipment power consumption and equipment maintenance costs
