Small-sized dual-input retarding mechanism test system

Abstract

The invention discloses a small-sized dual-input retarding mechanism test system. The test system comprises a motor I, wherein the motor I and a motor II are connected with two input shafts of a dual-input retarding mechanism respectively through a torque sensor I and a torque sensor II; the output shaft of the dual-input retarding mechanism is connected with the input shaft of a speed-up gearbox through a torque sensor III so as to drive the speed-up gearbox to rotate; the output shaft of the speed-up gearbox is connected with a loading motor shaft to drive a loading motor to rotate; the winding of the motor I and the winding of the motor II are connected in series and are equivalent to a motor, and the tachometer of the motor I and the tachometer of the motor II are connected in series and are equivalent to a tachometer to serve as speed feedback of a motor controller I. According to the method, current in the two motor windings is equal, and output torque is equal, so that the aim of common control of two motors can be achieved, a torque balance controlling method is simplified, and a motor controller is saved at the same time.

Description

technical field [0001] The invention relates to a small double-input deceleration mechanism test system, which belongs to the technical field of deceleration mechanism test systems.

This invention provides a synchronous control scheme for dual-motor drive sy...

AI Technical Summary

Problems solved by technology

[0005] The drive control of the double-input reducer can be completed by using dual motors and two motor controllers supplemented by an appropriate algorithm. The disadvantage is that the hardware system composition and control algorithm are relatively complex, and the debugging workload is large.

[0006] Magnetic powder brakes are often used in the loading test system of the reducer. The disadvantage of this loading method is that during the loading process, energy is consumed in the form of heat, and the cost is high
