Abstract
The utility model relates to an elevator part, in particular to an elevator tractor used for driving an elevator cage to move up and down. The elevator tractor comprises a seat body and a stator and a rotor which are arranged coaxially on the seat body, wherein the stator is fixed on the seat body and is provided with a coil, a cylindrical rotor covers on the periphery of the stator and the inner wall of the rotor is provided with a magnetic shoe, one end of the rotor is arranged on the center shaft of the seat body through a bearing, the end part of the rotor is fixedly connected with a braking disk and a belt wheel, and the seat body is also provided with a plurality of brakes matched with the braking disk. The elevator tractor has a simple structure, small volume, stable operation, good reliability and long service life.
Description
Technical field
The utility model relates to a kind of elevator components, specifically is a kind of upper and lower mobile elevator traction machine of lift car that is used for driving.
Background technology
Traditional elevator traction machine is generally by electrical motor, and drg, compositions such as drop-gear box and base, its running velocity be by speed-change gear control, thereby its transmission link is more, block construction is complicated falls.Not only volume is big, gear wear is serious, serviceability is low for it, driving efficiency is low, and in the gear mechanism operational process vibration and noise greatly, influenced its comfort.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, volume is little, the elevator traction machine of stable, good reliability, long service life.
Elevator traction machine of the present utility model includes a pedestal and coaxial stator and the rotor that is installed on the pedestal, stator is fixed on the pedestal and is provided with coil, the rotor cap stator of tubular peripheral and within it wall be provided with magnetic shoe, one end of rotor by bearing installation on the center shaft of pedestal, the end of rotor is fixedly connected with a brake disc and a belt wheel, also is provided with the drg that several cooperate with brake disc on pedestal.Be provided with in pedestal and outside frequency converter bonded assembly coder, described coder can be placed in the hollow center shaft.
The utility model can carry out stepless change by frequency converter and control its operation, and it is simple and compact for structure, volume is little, and noise and the vibration of having avoided gear transmission to produce have also improved driving efficiency, prolonged service life; In addition,, reduced machine elements, also just reduced wrong incidence, and need not periodic oil change, reduced use cost owing to gear case is not set.
Description of drawings
Fig. 1 is a vertical section structure scheme drawing of the present utility model;
Fig. 2 is an end face structure scheme drawing of the present utility model.
The specific embodiment
As shown in the figure, be coaxially installed with stator 2 and rotor 3 on the pedestal 1 of this elevator traction machine, stator is provided with coil 21, the cylindrical rotor that covers on the stator periphery is provided with magnetic shoe 31, rotor is installed on the center shaft 11 of pedestal by bearing 4, the end of rotor is fixedly connected with brake disc 5 and belt wheel 6, and brake disc is by two drgs, 7 brakings that are installed on the pedestal.Be provided with coder 8 in the hollow center shaft 11, in the elevator cage operation process, the data transmission that coder is gathered is sent instructions to the drg brake compensation by frequency converter, thereby can improve traveling comfort to frequency converter.
