Abstract

The invention discloses a coupling testing device, and aims to provide a magnetic coupling performance testing device capable of testing the maximum transmission torque and the transmission efficiency value at different temperatures. The device comprises an input shaft, a high-temperature test box, a coupling test piece and an output shaft, the coupling test piece is arranged in the hollow high-temperature test box, the left end and the right end of the coupling test piece are connected with the input shaft and the output shaft respectively, and flange supports used for fixing the input shaft and the output shaft are arranged on the two side walls of the high-temperature test box respectively. A gap exists between the coupling test piece and the inner surface of the high-temperature test box. The flange supports are adopted on the two side walls of the high-temperature test box to support the input shaft and the output shaft, the input shaft and the output shaft can axially and freely expand at a high temperature, and a gap exists between the circumference of the test piece and the high-temperature test box so that the test piece can be uniformly heated and expanded, the accuracy of performance test is improved, and local overheating is avoided. The design has a high practical value.

Description

technical field [0001] The invention relates to the field of coupling performance testing devices, in particular to a magnetic coupling performance testing device. Background technique [0002] The magnetic coupling is a non-contact coupling with magnetic transmission, which has the advantages of reliable sealing, good corrosion resistance, and no wear. With the continuous development of society, the demand for magnetic couplings used in high-temperature applications continues to expand. However, magnetic couplings have high temperature sensitivity, and as the temperature increases, the torque available for transmission by the magnetic coupling decreases gradually. [0003] Chinese Patent Publication No. CN112129526A, the publication date is December 25, 2020. The name of the invention is a high-precision test bench for the static and dynamic performance of a coupling. The application discloses a coupling with high static and dynamic performance. The precision test bench i...
