Abstract

The invention discloses a torque suction and discharge device based on an elastic pin mechanism. The device comprises a rail and elastic pins; a rail surface of the rail has an axis of rotational symmetry in the geometry; the rail surface is a cylindrical surface or other curved surfaces formed by reducing rotation; each of the elastic pins comprises a fixed support, a movable support, and a pressure spring; the support bodies of the movable supports and of the fixed supports are embedded end to end, and the support bottoms of the movable supports and of the fixed supports are used for clamping the pressure springs, so that a single sliding pair or a sliding pair capable of rotating at a certain angle is formed through the connection of the pressure springs; the support tails of the movable supports form the tips of the elastic pins; the elastic pin tips at the tail ends of the tips abut against the rail surface and move along the rail surface; the geometry of the elastic pin tips is matched with the geometry of the rail surface; and either the rail or the elastic pin is fixed on a torque suction and discharge shaft in a manner of simultaneously moving with the torque suction and discharge shaft, and the other one is fixed. According to the single-rail n-pin type torque suction and discharge device, the stretching and the retracting of the elastic pins are controlled through the cooperation of the elastic pins and the rail surface, so that the problem of instantaneous contradiction between power supply and load requirements is solved through the stretching and the retracting of the elastic pins, and the capacity of the torque transmission peak clipping and valley filling by needs is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical energy saving, in particular to a torque aspirator based on a pin mechanism. Background technique [0002] Torque (or torque) transmission is one of the basic forms of mechanical power transmission, and power, load and shaft are the three basic elements of torque transmission. Generally speaking, power and load have their own intrinsic torsional characteristics, but their intrinsic torsional characteristics often do not match, resulting in mixed torque transmission, accompanied by the reduction of the power and load's own energy conversion efficiency, torsional shock , torsional energy transfer loss, shortened device life and reduced reliability. [0003] Rotating shaft torsion power transmission devices have been found in every corner of production and life in today's society, but due to the common difference in torque characteristics between power and load, it is difficult for power and load...
