A permanent magnet torque calibration device

Abstract

The invention discloses a permanent magnet torque calibration device, which comprises a base, a fixed block, an outer magnet fixed block, a magnet inner fixed block, a rotating rod and a knob. The inner wall of the magnet outer fixed block is provided with two circles of first magnets in an annular array. Mounting holes, the outer wall of the magnet inner fixing block is provided with two circles of second magnet mounting holes matching the position and height of the first magnet mounting holes in an annular array, the inside of the first magnet mounting holes and the second magnet mounting holes Both are provided with magnets, and the rotating rod is fixedly installed concentrically with the fixed block inside the magnet, and the fixed block is fixedly installed on the top of the base. Use the difference in polarity between the magnets to realize the frustration when the knob rotates; use the mutual distance between the polarities of the magnets to realize the control of the rotational elasticity of each gear; the whole set of devices is tested by a standard torque sensor on the rotary torque test platform The torque of each gear is calibrated; after the calibration is completed, it is used to calibrate the torque standard calibration of other non-standard automation equipment.

Description

Technical field: [0001] The invention relates to a permanent magnet torque calibration device. Background technique: [0002] The torque limiter is a component that connects the main engine and the working machine. Its main function is overload protection. The torque limiter is used to limit the transmission system in the form of slippage when the required torque exceeds the set value due to overload or mechanical failure. The transmitted torque will automatically restore the connection when the overload situation disappears. In the production process of the torque limiter, different standard torque calibration devices need to be used for the torque qualification test. The traditional mechanical torque calibration device has low test accuracy and is prone to wear after long-term use, which affects its service life. Invention content: [0003] The technical problem to be solved by the present invention is to provide a device that utilizes the mutual distance between the po...
