Abstract

A wave-shaped spring is characterized in that the number of holes (2) of a wave spring (1), namely the number of wave peaks, can be determined as per the number of steel wires; an outer ring convex arc (3) and an inner ring convex arc (4) corresponding to each hole (2) are formed on the two sides of the corresponding hole (2); the outer ring convex arcs (3) are connected with outer ring arcs (6); the inner ring convex arcs (4) are connected with inner ring arcs (5); the wave spring (1) is wave-shaped along the periphery; due to the characteristics of the stressed wave spring (1), when one steel rope or multiple steel ropes of the group of steel ropes are subjected to oversize or underside force, the wave spring (1) deforms correspondingly; during deformation, the force is transmitted to other steel ropes to cause corresponding change to other steel ropes; therefore, when certain force is applied to the steel ropes, the wave spring (1) can uniformly distributes the force to each steel rope, the stress on the steel ropes can be balanced, and the purpose that all ropes in the group of steel ropes are subjected to equivalent force can be realized.

Description

technical field [0001] The invention relates to a spring in the shape of a wave, which can make the multi-heel steel wire rope used for lifting pass through the wave-shaped spring to balance the stress between the steel wire ropes, thereby achieving the purpose of improving the life of the steel wire ropes. Background technique [0002] With the continuous development of elevator drive technology, the lifting height and driving speed of the elevator have been greatly improved, but it also puts forward higher requirements for the safety and reliability of the elevator itself. At present, elevators at home and abroad are driven by traction machines. The suspension hoisting system of traction elevators is composed of main components such as traction wheels, steel wire ropes, and car / balance weight systems. The friction force generated by the winding in the traction wheel groove provides the direct power of lifting, and the movement of the car / balance weight is guided by the fle...
