Embodiment

[0022] Example: The installation and test steps of the test bench for the torsion transmission performance of the interference coupling are as follows:

[0023] 1. Install the loading components

[0024] Fix the hydraulic system 1 and the sliding bearing seat support seat 7 on the horizon iron 21 with bolts, fix the lower part of the two sliding bearing seat 5 to the upper part of the sliding bearing seat support seat 7 with bolts, and then place the shoulder of the loading shaft 6 on the two sides. In the clearance of the sliding bearing seat 5, the cylindrical shaft sections on both sides of the shoulder of the loading shaft 6 are matched with the cylindrical hole surface corresponding to the sliding bearing seat 5, and the profiled end of the loading shaft 6 is placed close to the edge of the ground iron 21. Fix the upper part of the sliding bearing seat 5 and the loading shaft 6 until there is slight resistance when the loading shaft 6 rotates. Next, the uncurved end prof...

Abstract

The invention discloses a test bench for detecting the torque transmission performance of a thin-wall interference coupling piece, belongs to the technical field of mechanical detection, and relates to a universal test bench for detecting the torque transmission performance of the thin-wall interference coupling piece. The test bed is composed of a loading assembly, a load conversion and acquisition assembly and a movable supporting assembly. In the test bed, a steel wire rope flexible loading structure is adopted in order to prevent the interference connecting piece from being subjected to the action of additional bending moment. A laser displacement sensor and a torque sensor are synchronously integrated to detect and judge the interference connection failure condition, so that the synchronous acquisition and data processing functions of the test bed are realized; by utilizing a supporting structure form of combining the roller linear guide rail and the test piece support, the function of rapidly and movably supporting the test bench is realized in the process of detecting the torsion transmission performance of a large batch of interference pieces. The test bench is simple in overall structure, convenient to operate, comprehensive in function, accurate and reliable, enlarges the detection range of the torque transmission performance of the interference part, and improves the detection accuracy of the torque transmission performance of the interference connecting part.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing, and relates to a general test bench for testing the torque transmission performance of a thin-walled interference coupling. Background technique [0002] The interference connection is the main static connection method to realize the torque transmission of the bushing parts, and the torque transmission performance is an important basis for the structural design of the interference connection and the main evaluation index for the actual connection performance. At present, torque is mainly measured by the structure of the force arm with the additional structure of the force measuring device or the additional coupling of the torque sensor. In the latter, the coupling usually adopts the elastic sleeve pin coupling, the plum-shaped elastic coupling, and the tire coupling. , Diaphragm coupling and other elastic couplings to avoid the problem of misalignment of the loading shaft caused by par...
