Abstract

The invention discloses a motor rotor rotating shaft improved structure, which comprises a locating structure arranged on a shaft head at the tail end of a rotating shaft. The motor rotor rotating shaft improved structure has the advantages of simple structure and convenience for making, and can be used for rapidly locating the rotating shaft and effectively preventing a bearing from bearing an overlarge axial force and protecting the bearing in a motor assembling process.

Description

A kind of motor rotor shaft improves structure
Technical field
The present invention relates to electric machine structure, particularly a kind of improvement structure of motor rotor shaft.
Background technology
As shown in Figure 1, the rotating shaft 01 of rotor 02 is positioned in the motor case by bearing, bearing generally can not bear excessive axial force, and in general assembling process, after having assembled bearing on the terminal spindle nose 011 of rotating shaft or the axle journal 012, when being installed to rotor in the motor case again, because rotating shaft need align, adjust, therefore have mobilely in the axial direction, having greatly, possibility can make bearing bear axial force.Because the relation that contacts the location is arranged between the spindle nose of rotating shaft end and the motor rear portion end cap, bearing on the terminal spindle nose of rotating shaft is easier to be subjected to bigger axial force so be assemblied in, and may damage bearing when serious.
Summary of the invention
Problem to be solved by this invention just provides a kind of motor rotor shaft and improves structure, and is simple in structure, easy to make, and positioning rotating shaft also effectively avoids bearing to bear excessive axial force fast, the safety of protection motor assembling process middle (center) bearing.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of motor rotor shaft improves structure, it is characterized in that: comprise the location structure on the spindle nose that is located at the rotating shaft end.
Further, described location structure is the shaft shoulder that is located on the spindle nose end face, the location hole corresponding matching that the shaft shoulder and motor posterior end cover.
Further, the junction of the described shaft shoulder and spindle nose is provided with annular shallow slot.Avoid stress to concentrate.
After adopting technique scheme, the present invention has following advantage: contact location, stressed by the newly-increased shaft shoulder with motor rear portion end cap, can play a very good protection to the bearing that is assemblied on the terminal spindle nose of rotating shaft.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of existing motor rotor shaft;
Fig. 2 is the structural representation of an embodiment of the present invention.
Embodiment
The structural representation of an embodiment of the present invention as shown in Figure 2, a kind of motor rotor shaft improves structure, comprise the location structure on the spindle nose 11 that is located at rotating shaft 1 end, described location structure is the shaft shoulder 13 that is located on the spindle nose end face, the location hole corresponding matching that the shaft shoulder and motor posterior end cover.Contact location, stressed by the newly-increased shaft shoulder with motor rear portion end cap, can play a very good protection the bearing that is assemblied on the terminal spindle nose of rotating shaft.
In the foregoing description, the junction of the shaft shoulder and spindle nose is provided with annular shallow slot 14, can effectively avoid stress to concentrate.
Except that above preferred embodiment, the present invention also has other execution mode, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.

Claims (3)
