Abstract
The utility model relates to an asynchronous motor with an outer rotor, which comprises an inserted line stator, an outer rotor, a bearing seat and an end cover, wherein the inserted line stator is fixedly connected with the bearing seat; a winding of the outer rotor is positioned on the outer side of the inserted line stator; a rotating shaft of the outer rotor is connected with the bearing seat by a bearing; the bearing seat is connected with the end cover by a fastener. The utility model provides an asynchronous motor with an outer rotor, which has the advantages of low requirements for an installation technology and simple maintenance and disassembly.
Description
(1) technical field
The utility model relates to a kind of asynchronous motor of outer rotor.
(2) background technology
The relative normal asynchronous of asynchronous motor of outer rotor has higher stock utilization, when being used for blower fan, advantages such as compact conformation is arranged again.But existing asynchronous motor of outer rotor structurally is unfavorable for processing and maintenance, and often end cap and bearing pedestal being combined is a part, has at least a bearing to be contained on the end cap.In motor assembling technology, when stator directly is pressed into end cap, bring quality problems such as off-centre, broken string easily, return repair demolition and bring very big difficulty.
(3) summary of the invention
In order to overcome the deficiency of existing asynchronous motor of outer rotor mounting process requirement height, repair demolition trouble, the utility model provides that a kind of mounting process requirement is simple, the simple asynchronous motor of outer rotor of repair demolition.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of asynchronous motor of outer rotor, comprise rule stator, external rotor, bearing pedestal, end cap, described rule stator is fixedlyed connected with bearing pedestal, the winding of described external rotor is positioned at the outside of this rule stator, be connected by bearing between the rotating shaft of described external rotor and the bearing pedestal, be connected by securing member between described bearing pedestal and the end cap.
Further, described bearing pedestal is made up of front-end bearing pedestal, rear bearing block, is connected by securing member between described front-end bearing pedestal and the end cap; Be connected by bearing between described rotating shaft and front-end bearing pedestal, the rear bearing block.
Further again, described end cap is provided with and protects mouth, and the lead-in wire of described rule stator passes this and protects mouth.
The rotating shaft one side construction opening back-up ring in the described bearing outside, described split washer is used for axial restraint; Opposite side is installed elastic washer, and described elastic washer is regulated end play.
Described securing member is a fastening bolt.
Beneficial effect of the present invention mainly shows: 1, adopt between end cap and bearing pedestal securing member to be set, motor adds man-hour, can be pressed into stator to bearing pedestal earlier after, reprocessing bearing chamber size, mounting process is simple; 2, connect by securing member between bearing pedestal and the end cap, be convenient to dismounting, easily stator winding is repaired; 3, bearing pedestal is divided into front-end bearing pedestal, rear bearing block, can guarantees the requirement of the concentricity of former and later two bearing chambers and rule stator.
