Self-balancing elevator traction sheave and production method thereof

Abstract

The invention discloses a self-balancing elevator traction sheave and a production method thereof, comprising a working board, a rotating structure and a riser, the rotating structure is installed on the bottom of the working board, and two sets of rising boards are installed on the top of the working board ; The top of the working board is evenly equipped with four groups of fixed plates, wherein the backs of two groups of fixed plates and the fronts of other two groups of fixed plates are respectively attached to the front and back of two groups of vertical plates, and the fixed plates are close to An electric telescopic rod is installed on one side outer wall of the fixed limit ring. The invention can be poured in blocks, and the traction wheel is divided into three parts for manufacture, and the three parts are assembled during use. If the traction wheel is damaged, one of the components can be replaced accordingly, and then the purpose of reducing the replacement of materials is achieved. When grinding, the parts that grind the ring rope groove can be ground and adjusted. At the same time, the pressing plate is used to contact and press the traction sheave to prevent shaking. The laser surface quenching and hardening treatment can be carried out during the manufacturing process to increase wear resistance.

Description

technical field [0001] The invention relates to the technical field of traction sheaves, in particular to a self-balancing elevator traction sheave and a production method thereof. Background technique [0002] The traction sheave is the sheave on the elevator traction machine, also known as the traction sheave or the driving sheave. It is the device for the elevator to transmit the traction power. The elevator can transmit the traction power through the friction force between the wire rope and the groove surface of the traction sheave. The traction sheave is an important part of the safe drive of the elevator. The flange groove of this part needs to bear all the dynamic and static loads of the car, the load, and the counterweight. Therefore, the traction sheave must have high strength, toughness, and wear resistance. resistance and impact resistance. [0003] The defective of existing a kind of self-balancing elevator traction sheave and production method thereof is: [0...

AI Technical Summary

Problems solved by technology

"However, this method lacks the operation of surface quenching on the annular rope groove of the traction sheave. The internal and external strength of the traction sheave is consistent, and the fatigue strength of the annular rope groove is average, resulting in low wear resistance.
