Contactless override mechanism

Abstract

The invention discloses a contactless override mechanism, which comprises an inner ring and an outer ring, wherein the inner ring is provided with one or two or more than two inner slide frames, one end of each inner slide frame is provided with a hollow opening, an inner spring is arranged in each inner slide frame, one end of each inner spring is fixedly arranged at the end part of the corresponding inner slide frame, and the other end of each inner spring is connected with an inner slide block which can slide in the corresponding inner slide frame; the outer ring is provided with outer slide frames which have the same number as the inner slide frames, an outer spring is arranged in each outer slide frame, one end of each outer spring is fixedly arranged at the end part of the corresponding outer slide frame, the other end of each outer spring is connected with an outer slide block which can slide in the corresponding outer slide frame, and each inner slide block is engaged with the corresponding outer slide block at a gap of the inner ring and the outer ring. The contactless override mechanism has the advantages that the structure is simple, and the manufacturing is easy; the traditional contact type override rotation is overcome, the heating and serious abrasion are avoided, the service life of the override mechanism is effectively prolonged, and the normal running of installed mechanical equipment is guaranteed; the transmission is reliable, the rotation speed of override is high, and the contactless override mechanism is suitable for being widely popularized.

Description

technical field [0001] The invention relates to an overriding mechanism, in particular to a non-contact overriding mechanism. Background technique [0002] An overrunning mechanism, also known as a one-way clutch or a one-way bearing, is a device that can only transmit power from one direction. When the speed of the driving raceway is the same as that of the driven raceway, it rotates, and when the speed of the driving raceway is lower than that of the driven raceway, the driven raceway can rotate freely. Override mechanisms are widely used in aircraft, tanks, military trucks, heavy trucks, off-road vehicles, loaders, ships, forklifts, automobiles, motorcycles, lathes, printing machinery, spring machines and other mechanical equipment. [0003] Most of the traditional overriding mechanisms are contact-type. The principle is to use the meshing of the teeth, the meshing of the ratchet-pawl or the wedging action of the roller and the wedge to move or torque in one direction. T...

Problems solved by technology

[0003] Most of the traditional overriding mechanisms are contact-type. The principle is to use the meshing of the teeth, the meshing of the ratchet-pawl or the wedging action of the roller and the wedge to move or torque in one direction. The CKS type is a common contact-type overriding mechanism. Mechanism, when it is running at high speed, the outer ring and the meshing parts will have friction, which will cause heat generation and severe wear and tear. On the one hand, the service life of the overrunning mechanism will be shortened, and on the other hand, the normal operation of mechanical equipment will be affected.
