Abstract
The utility model relates to an armature axial fixing structure of a motor. In the armature axial fixing structure of the motor, an armature is arranged on the motor, a first C-shaped stop ring, a spring and a second C-shaped stop ring are arranged on the armature, the spring is positioned between the first C-shaped stop ring and the second C-shaped stop ring, the armature is sleeved on a rolling bearing, and the rolling bearing is positioned between the spring and the second C-shaped stop ring. The armature axial fixing structure of the motor reduces a limit screw, a shaft plug and an adjusting screw compared with the same industrial products on the basis of achieving motor performance requirements and controlling the axial movement and just additionally uses one C-shaped stop ring which is at least reduced by more than 100 times compared with the single shaft plug on the market on the aspect of price, thereby saving the cost, reducing the parts, lightening the mass of motor parts, shortening the installation man-hour, and also improving the working efficiency.
Description
Technical field
The utility model relates to a kind of fixed structure, and the armature shaft that relates in particular to a kind of motor is to fixed structure.
Background technology
Armature is an important component part of micromotor, its installation and the fixing performance that directly has influence on motor.Existing armature shaft has adopted a C type circle, a spring, a banking pin and an adjustment screw to form to the front end that fixed structure has plenty of at armature.Thereby main shaft can wear and tear with banking pin friction banking pin during owing to the armature high speed rotating, and axial endplay can occur again like this, so added the axle plug of a high temperature resistant rub resistance again between banking pin and front-end of spindle.Yet the price comparison height of axle plug makes the installation cost of motor component increase, and in that many installations of these parts of axle plug on the basis of spring are housed, must increase installation work-hour, has reduced operating efficiency.
The utility model content
The utility model at existing armature shaft to the appearance of fixed structure for fear of axial endplay, fill in and between stop screw and front-end of spindle, increase axle, make the installation cost of motor component increase, and the installation of many these parts of axle plug, must increase installation work-hour, reduced the deficiency of operating efficiency, the armature shaft that a kind of motor is provided is to fixed structure.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of armature shaft of motor is that armature is installed on motor to fixed structure, the one C type back-up ring, spring and the 2nd C type back-up ring are installed on described armature, described spring is between the first C type back-up ring and the 2nd C type back-up ring, described armature is inserted on the rolling bearing, and described rolling bearing is between spring and the 2nd C type back-up ring.
The beneficial effects of the utility model are: the armature shaft of the utility model motor requires and can control on the basis of axial endplay reaching motor performance to fixed structure, lacks than the product of the same industry and has used a banking pin, an axle plug and an adjustment screw; Only used a C type back-up ring, and the single axle plug price on the market is more than 100 times of single C type back-up ring at least more, thereby has saved cost, reduced parts, alleviated the quality of motor component, reduce installation work-hour, improved operating efficiency simultaneously.
Description of drawings
Fig. 1 is the structural representation of the armature shaft of the utility model motor to fixed structure.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Fig. 1 is the structural representation of the armature shaft of the utility model motor to fixed structure.As shown in Figure 1, the armature shaft of described motor is that armature 1 is installed on motor to fixed structure, the one C type back-up ring 2, spring 3 and the 2nd C type back-up ring 5 are installed on described armature 1, described spring 3 is between the first C type back-up ring 2 and the 2nd C type back-up ring 5, described armature 1 is inserted on the rolling bearing 4, and described rolling bearing 4 is between spring 3 and the 2nd C type back-up ring 5.
Described rolling bearing 4 is fixed on the motor, a described C type back-up ring 2 and the 2nd C type back-up ring 5 are pushing the both sides that spring 3 is stuck in rolling bearing 4 respectively, make significantly axial endplay of armature like this, the spring 3 between a C type back-up ring 2 and the 2nd C type back-up ring 5 is in order to cushion axial endplay.Armature just can fixedly mount like this, has also solved the armature axial endplay and has brought noise problem.Reached the noise requirement of motor.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
