Torsional spring mechanism generating symmetrical torque

Abstract

A torsional spring mechanism generating symmetrical torque mainly comprises fixed pins, torsional springs, connecting pins, a power shaft and a sleeve. Positioning holes are reserved on the side wall of the sleeve and a mounting hole abutted with the other device is reserved at the bottom of the sleeve. The torsional springs are of cylindrical structures, positioning holes are reserved on one ends of the torsional springs and strip-shaped grooves are reserved on the other ends of the torsional springs along the outer walls. During operation, two torsional springs are arranged in the sleeve, the fixed pins penetrate through the positioning holes to fix relative positions of the torsional springs and the sleeve, the power shaft is positioned in the torsional springs, two positioning holes are reserved at one end of the power shaft, two connecting pins penetrate through mounting holes on the power shaft and the strip-shaped grooves on the torsional springs to connect the power shaft and the torsional springs, the sleeve is fixed on the other device, and the power shaft rotates to drive the torsional springs to rotate to deform to generate torque. The problem that equipment like a servo mechanism has asymmetrical torque during running-in is solved, and the torsional spring mechanism is simple and effective in structure, low in cost and easy to produce on a large scale.

Description

technical field [0001] The invention relates to a torsion spring mechanism, in particular to a torsion spring mechanism generating symmetrical torque. [0002] Background technique [0003] After the equiaxial output control equipment of the servo mechanism is manufactured, the whole machine needs to be run-in under the condition that the output bearing is subjected to a certain torque force. The torque is positive and negative torque, and the torque increases with the increase of the shaft rotation angle. The torque force at the angular displacement is equal in magnitude. At present, the main technical solution to solve the above-mentioned problems is to use a loading platform, which is equipped with an elastic torsion plate. One end of the elastic torsion plate is fixed, and the other end can only rotate around the center line of the torsion plate. There is a gap between the torsion plate and the output shaft of the servo mechanism. Interface, the rotation of the output ...

Problems solved by technology

Due to the large volume and weight of the loading table in general, it is extremely inconvenient to connect with the servo mechanism and other equipment. In addition, the special loading table is very expensive.
