Abstract
An extra thin front-end cover of a motor comprises a thin-shelled front-end cover body, a cover plate and a bearing. The middle of the front-end cover body is provided with a concave stage that concaves toward to the inner side, and the middle of concave stage is provided with a round hole, the inner side of the round hole is connected with a bearing chamber, the front end of the bearing chamber is provided with a curling edge that turns inward. The bearing is arranged in the bearing chamber and is pressed against the curling edge, the cover plate is connected on the concave stage of the front-end cover body to form an outside baffle of the bearing, and a round hole in the middle of the cover plate reveals a bearing hole. The extra thin front-end cover of the motor of the invention facilitates to make thinner motors.
Description
Technical field
The present invention relates to a kind of motor component, relate in particular to a kind of front end housing of ultra-thin electric motor.
Background technology
In some technical field, run into some through regular meeting and be subjected to the spatial dimension restriction to need to adopt the situation of thin motor.For example at the car production field, the installation site of radiator fan is just very little, has only that to do enough flat to fan assembly, can guarantee that just there is big as far as possible gap in the space, thereby running under the situation of bringing to a halt, avoiding fan assembly to be subjected to the impact of water tank, generator etc.Fan assembly comprises fan housing, fan blade and motor, its gross thickness depends mainly on the thickness of motor, the thickness of motor then is decided by to form the thickness sum of the armature and the front and rear cover of motor, therefore, a motor to be made ultra-thin shape structure, must all make the ultra-thin shape structure Design of adaptation the structure of armature and front and rear cover.
Summary of the invention
Purpose of the present invention is exactly in order to provide a kind of front end housing of ultra-thin electric motor.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of front end housing of ultra-thin electric motor, comprise shell shape front end housing body, cover plate and bearing, be provided with a recessed to the inside concave station in the centre of front end housing body, be provided with a circular hole in the centre of concave station, the inboard of circular hole is connected with a bearing chamber, the front end of bearing chamber is provided with the crimping of inside upset, bearing is arranged in the bearing chamber and is pressed on the crimping, cover plate is connected on the concave station of front end housing body and forms the outer side shield of bearing, and the centre of cover plate is provided with circular hole and exposes by dead eye.
Described front end housing body is provided with a circle louvre, is provided with radially reinforcement between each louvre.
Described louvre comprises mounting hole and circular hole, and mounting hole and circular hole are arranged alternately.
Described front end housing body edges is respectively equipped with reinforcement in the center corresponding to each mounting hole.
Described cover plate is riveted with the concave station on the front end housing body and is linked to each other.
The front end housing of ultra-thin electric motor of the present invention helps to do motor more flat.
