Self-balancing symmetrical loading device

Abstract

The invention discloses a self-balancing symmetrical loading device. A loading sliding block bracket is arranged in a chute of a chute bracket and is matched with the chute in a slid way; a loading sliding block is arranged in the loading sliding block bracket and matched with the loading sliding block bracket in the slid way; a bracket offsetting spring check block is arranged at the end port part of the chute bracket; a loading stud bolt passes through the loading sliding block bracket and the bracket offsetting spring check block and then is pressed against the loading sliding block; the loading sliding block bracket and the loading sliding block are provided with corresponding arc grooves respectively; two sides of the arc grooves are provided with sliding block offsetting springs respectively; and a bracket offsetting spring I is arranged between the loading sliding block bracket and the inner wall of the chute bracket, and a bracket offsetting spring II is arranged between the loading sliding block and the bracket offsetting spring check block. The self-balancing symmetrical loading device can achieve the effect of zero moment self-balancing symmetrical loading by driving the loading stud bolt, and also can achieve the effect of self-balancing zero moment uniform unloading of the loading device by driving the loading stud bolt in an opposite direction; and the zero moment loading or unloading can be realized when a torque of an axis is detected, so test data of the detected torque of the axis are more correct and more real.

Description

technical field [0001] The invention relates to a loading device for shafts, in particular to a self-balancing symmetrical loading device. Background technique [0002] In order to ensure the stable and reliable operation of various power systems after installation, each subsystem in the load spectrum test must calibrate the torque of the power output shaft, and the torque test data is the most important test data in the load spectrum test, and its accuracy needs to be guaranteed. [0003] In the prior art, the commonly used mechanical torque loading devices basically apply bending moment to the shaft while torque is applied to the shaft. In studies of loading on shafts, shafts are generally subjected to torque and bending moments. When detecting the torque of the shaft, it is bound to be affected by the bending moment, thus affecting the detection accuracy. Therefore, the single torque loading and bending moment loading have great significance for the research of the shaf...
