Abstract

The invention provides a non-contact type mechanical energy transmission test platform and a test method thereof. Transmission from a distance is realized by utilization of the superconducting flux pinning effect; namely, an invisible magnetic flux line captured by a superconductor is connected to a superconducting driving part and a permanent magnet follower, so that power and motion are transmitted; the test platform is mainly composed of a superconducting assembly, a permanent magnet assembly, a rotation speed sensor, a torquemeter and the like; the permanent magnet assembly is composed ofan even number of permanent magnet balls embedded in a circular disc at the driven shaft end; the force of rotary motion is provided for the superconducting driving part through a servo motor; the torquemeter connected with the driven shaft obtains the amplitude of the transmission torque; the amplitude of the transmission rotation speed is obtained through the rotation speed sensor; and an adjusting mechanism realizes clearance adjustment between the superconducting driving part and the permanent magnet follower. The non-contact type mechanical energy transmission mode provided in the invention is a mode of self-steady transmission from a distance; and mechanical energy transmission requirements on places, such as closed spaces, toxic substance stirring and high cleanliness requirement, can be satisfied.

Description

technical field [0001] The invention relates to the technical field of mechanical energy transfer modes and testing instruments, in particular to a non-contact mechanical energy transfer test bench based on superconducting magnetic flux pinning effect and a test method thereof. Background technique [0002] The transmission of mechanical energy can be seen everywhere in engineering, and generally refers to the use of mechanical means to transmit power and motion. Specifically, it can be divided into two categories: one is to achieve transmission by friction between the parts, such as belt transmission; the other is to achieve transmission by the meshing of the active part and the driven part or the meshing of intermediate parts, such as gear transmission and chain transmission. wait. These traditional mechanical energy transmission methods are all mechanical contact, that is, the active part and the driven part are in direct contact or connected as a whole through intermedi...
