Abstract

The utility model relates to a rotor and back end plate assembly structure which belongs to the motor producing and manufacturing technology field; wherein the back end plate is formed with an axle bumper and firmly provided with a bearing, a rotor shaft is matched with the bearing and rotatable connected with the back end plate, a process hole of the end part of the rotor shaft is provided with a protective sleeve, and the protective sleeve is provided with a rounded end corresponding with the axle bumper and a small end matched with the process hole of the rotor shaft. The utility model can effectively reduce the wear of the rotor shaft end part and the back end plate, which thereby prolongs the service life of the motor, reduces the noise in the operation process of the motor, and solves the problems of that the wear of the rotor shaft and the back end plate is comparatively serious in the exiting technology, which influences the service life of the motor, and the noise in the operation process of the motor is larger.

Description

Rotor and end plate assembly structure
Technical field
The utility model relates to a kind of rotor and end plate assembly structure, belongs to the technical field that motor is manufactured.
Technical background
In the existing electric machine structure; often be fixed with various bearings with the rotatably supported end plate of armature spindle; armature spindle one end then cooperate with bearing realize with end plate between be rotatably connected; and owing to the axial displacement that can take place at motor operation course rotor axle in various degree; therefore armature spindle end regular meeting and end plate rub corresponding to the armature spindle end portion; thereby cause the wearing and tearing of armature spindle end and end plate; shortened the useful life of motor; simultaneously; because the armature spindle end is generally planar structure; therefore the friction between armature spindle end and the end plate is just even more serious, has also caused the bigger problem of noise in the motor operation course.
Summary of the invention
The utility model purpose is to provide a kind of wearing and tearing that can reduce armature spindle end and end plate effectively, thereby prolonged the useful life of motor, and the rotor and the end plate assembly structure of the noise in the motor operation course have been reduced, the armature spindle and the end plate wearing and tearing that have solved the prior art existence are more serious, influenced the useful life of motor, and problem such as noise is bigger in the motor operation course.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: rotor and end plate assembly structure; be formed with axle bumper on the end plate and be installed with bearing; armature spindle cooperates with bearing and is rotatably connected with end plate formation; the fabrication hole of described armature spindle end squeezes protective sleeve is housed, the small end that described protective sleeve has the sphere end corresponding with axle bumper and cooperates with the armature spindle fabrication hole.Set up protective sleeve with sphere end in the armature spindle end; avoided direct contact the between armature spindle end and the end plate; the wearing and tearing of armature spindle have been reduced; prolonged the useful life of motor; simultaneously; owing to adopt sphere contact between protective sleeve and the end plate,, thereby reduced the noise in the motor operation course so protective sleeve and the end plate contact-making surface between directly is also less.
As preferably, be provided with pad between the axle bumper of described end plate and the protective sleeve of armature spindle.Wherein, between end plate and protective sleeve, set up pad and avoided direct contact the between protective sleeve and the end plate, thereby reduced the wearing and tearing of end plate, prolonged the useful life of motor.
As preferably, the small end of described protective sleeve comprise the cylindrical section of head and be located at cylindrical section and the sphere end between conical section.Wherein, the small end of protective sleeve adopts cylindrical section and conical section structure, and the small end of protective sleeve and the fabrication hole of armature spindle end are joined, and makes protective sleeve more reliable in the location of armature spindle end.
Therefore, the utlity model has and to reduce the wearing and tearing of armature spindle end and end plate effectively, thereby prolonged the useful life of motor, and reduced the characteristics such as noise in the motor operation course.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A place partial enlarged drawing of Fig. 1;
Fig. 3 is a kind of structural representation of the utility model protective sleeve.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2; be formed with axle bumper 2 on the end plate 1 and be installed with bearing 3; armature spindle 4 cooperates with bearing 3 and is rotatably connected with end plate 1 formation; the fabrication hole of armature spindle 4 ends squeezes protective sleeve 5 is housed; be provided with pad 6 between the axle bumper 2 of end plate 1 and the protective sleeve 5 of armature spindle 4; as shown in Figure 3; the small end 8 that protective sleeve 6 has the sphere end corresponding with axle bumper 27 and cooperates with the fabrication hole of armature spindle 4, small end 8 comprise the cylindrical section 9 of head and be located at cylindrical section 9 and sphere end 7 between conical section 10.Set up protective sleeve with sphere end in the armature spindle end; avoided direct contact of asking of armature spindle end with end plate; the wearing and tearing of armature spindle have been reduced; prolonged the useful life of motor; simultaneously; owing to adopt sphere contact between protective sleeve and the end plate,, thereby reduced the noise in the motor operation course so protective sleeve and the end plate contact-making surface between directly is also less.Between end plate and protective sleeve, set up pad and avoided direct contact the between protective sleeve and the end plate, thereby reduced the wearing and tearing of end plate, prolonged the useful life of motor.
