Problems solved by technology

Its defect is that it can only simulate the sliding wear of the simple friction pair between the disc and the block, and cannot simulate the friction and wear of the groove surface friction pair between the elevator traction sheave rope groove and the steel wire rope at all, so it cannot be applied to elevators. Rolling-sliding contact fatigue wear test between traction sheave groove and wire rope

Abstract

This invention relates to traction and drive rolling-sliding contact fatigue wear-test machine of elevators, in which, the steel wire rope in the structure of double-groove double-rope semi-circle complement is fixed on a rope groove of a down turnplate, namely, two grooves are opened on the turnplate, a steel wire rope, a bit longer than semi-circle, is winded in each groove, the upper and lower semi-circle ropes are complemented, after that, the rope is fixed in the down turnplate with a clamp, this structure can reduce and avoid the contact vibration between the traction wheel and the rope, the weight amplifies the force by a loaded lever to press the traction wheel to contact with the rope on the down turnplate, the action line of the pressure passes through the center of the two wheels.

Description

technical field [0001] The invention relates to equipment in the technical field of machinery, in particular to an elevator traction drive rolling-sliding contact fatigue wear testing machine. Background technique [0002] Abrasion testing machine is an experimental device for testing the load-carrying capacity of lubricants or the material wear characteristics of mating pairs. Elevator traction drive rolling-slip contact fatigue wear testing machine is mainly used to test the friction and wear characteristics of traction sheave and wire rope under different materials and loads. Due to various reasons in the design, material selection, manufacture, installation and traction system itself, after a period of operation of the elevator, the rope grooves on the traction sheave that are in contact with the traction wire rope will be worn to varying degrees. With the increasing degree of wear and tear, the elevator often makes abnormal noises during operation, accompanied by car s...
