Abstract
The utility model discloses a shaftless electric motor, comprising a shell, a stator, a rotating bearing and a rotor, wherein an opening is arranged at the front end of the shell, the stator is arranged on the inner wall of the shell, the rotating bearing is arranged at the rear end of the shell, the rotor is fixedly connected with the rotating bearing, and a flange disc is welded on a front end port of the rotor. The shaftless electric motor disclosed by the utility model has the beneficial effects of small size, simple structure, material saving performance, and capability of preventing the occurrence of the problems of abrasion, low transmission efficiency and the like caused by the sliding between a rotating shaft and a transmission belt.
Description
Technical field
The utility model relates to a kind of motor technology, particularly a kind of shaftless motor.
Background technology
Used motor all is to adopt rotation axis to drive transmission to bring the running of realization plant equipment at present, and such motor has following shortcoming: the first, often occur between rotation axis and the driving-belt sliding, and transmission efficiency is low; The second, use after a period of time rotation axis very easily to wear and tear to produce eccentric, the noise when working again is greatly even might damage the stator and the rotor of motor; The 3rd, the installation of motor, dismounting, maintenance are cumbersome.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of shaftless motor.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of shaftless motor, comprise front opening housing, be installed in stator on the inner walls, be installed in the rolling bearing and the rotor of fixedlying connected of housing rear end, welding flange on the front port of rotor with rolling bearing.
Rotor is connected with bolt by ring flange with power transmission shaft on the machinery equipment, not only is connected firmly but also the transmission efficiency height.
Be welded with fixation kit on the outward flange of housing front end, convenient fixed installation.
The shaftless motor that utilizes the technical solution of the utility model to make, remove the original rotation axis of motor and used the flange ways of connecting instead and not only saved material, also avoided the generation of problems such as the wearing and tearing that cause because of the slip between rotation axis and the driving-belt and transmission efficiency be low.The simple and convenient maintenance of whole apparatus structure, the transmission efficiency height.
