Ultra-thin butterfly type tractor for elevator

Abstract

The invention discloses an ultra-thin butterfly type tractor for an elevator. The tractor comprises a machine base and an elevator guide rail. A mandrel is arranged in the middle of the left side faceof the machine base. A groove is formed in the middle of the left side face of the mandrel. An encoder is arranged in the groove. A protection plate is fixedly installed on the right side face of themachine base. A bearing rear gland located in the groove is fixedly installed on the left side face of the protection plate. The left side face of the bearing rear gland is connected with the encoderthrough bolts. The outer surface of the mandrel is provided with a sealed self-aligning roller bearing located in the machine base and a sealed deep groove ball bearing located on the right side of the sealed self-aligning roller bearing. The whole tractor is novel in structure and more reasonable in design, the back side of the guide rail can closely abut against the tractor, the encoder can bedetached and assembled after the tractor is installed on the guide rail, the tractor does not need to be detached from the guide rail, the whole tractor is small in axial size which can be 190 mm or below, the space layout of the elevator is better facilitated, automatic production can be realized, and the assembling process is simple.

Description

technical field [0001] The invention relates to a traction machine, in particular to an ultra-thin butterfly traction machine for elevators. Background technique [0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator main engine. Its function is to transmit and transmit power to make the elevator run. The guide wheel is generally installed on the frame or the load-bearing beam under the frame. Some of the turning hand wheels are fixed on the motor shaft, and some are usually hung on the nearby wall. When in use, they are then set on the motor shaft. The volume and thickness of the existing traction machines are mostly large, which is not conducive to the layout of the elevator space during use. Therefore, we improve this and propose an ultra-thin butterfly traction machine for elevators. Contents of the invention [0003] In order to solve the problems of the technologies described above, the present invention provides t...
