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 motion friction and wear between the rope groove of the elevator traction sheave and the wire rope at all, so it cannot be applied to the

Abstract

The invention relates to abrasion machine of the elevator towing contacting tiredness. The variable-frequency electric machine drives the towing wheel to rotate by the shaft coupling and the bearing block after the reducer; one end of the cable wire is connected to the arc framework and the other is connected to the draught spring after fixing the two end with the lantern ring by the clap; it changes the pressure and the friction force between the cable wire and the wheel slot by changing the tension force of the cable wire by loading the hand wheel to draw the spring. So it can get the friction force by the fore-and-aft pulling force. So the invention can test the sliding friction and the abrasion character in the different condition to provide the data for designing the elevator towing.

Description

technical field [0001] The invention relates to equipment in the technical field of machinery, in particular, an elevator traction drive sliding contact fatigue wear tester. Background technique [0002] Wear testing machine is an experimental device for testing the load-carrying capacity of lubricants or the friction and wear characteristics of mating pairs. Elevator traction drive sliding contact fatigue wear testing machine is mainly used to test the sliding wear characteristics of the rope groove of the traction sheave and the wire rope under different materials, loads and wrap angles. 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. Among them, in addition to rolling friction wear, there is also a kind of slipping or sliding friction wear cause...
