Abstract
The utility model discloses an improved rotating shaft structure of a motor rotor, comprising a rotating shaft and a rotor installed on the rotating shaft, wherein the rotating shaft is provided with a shaft shoulder structure on the external side of a bearing mounting position. Because the rotating shaft of the motor rotor is provided with the shaft shoulder structure on the external side of the bearing mounting position, and the shaft shoulder can be positioned and stressed after final assembly, the bearing is protected.
Description
Technical field
The utility model relates to a kind of improved structure of rotating shaft of rotor.
Background technology
Rotor is one of main parts size in the motor, is made up of armature spindle, iron core, coil, and its shaft both sides are wanted finish turning processing and bearing is installed, and then are installed on the motor casing.But existing armature spindle design, after the final assembling of bearing, bearing outside end face is almost parallel with axial end, when so final rotor is worked, because the axial endplay of rotating shaft, motor casing can directly put on the bearing inner ring the impulsive force of axle, the wearing and tearing of having accelerated bearing, even can damage bearing.
The utility model content
Technical problem to be solved in the utility model just provides a kind of bearing inner ring and motor casing of preventing and produces the improved structure of rotating shaft of the rotor that impacts.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of improved structure of rotating shaft of rotor comprises rotating shaft and is installed on rotor in the rotating shaft that it is characterized in that: described rotating shaft is provided with shaft shoulder structure in the outside at Bearing Installation place.
As preferably, the end face of the described shaft shoulder is provided with chamfering.
As preferably, described rotating shaft with the cooperation place external diameter of rotor on scribble the anaerobism glue-line.
The utility model is owing to adopted technique scheme, and the rotating shaft of rotor is provided with shaft shoulder structure in the outside at Bearing Installation place, and this shaft shoulder can have been protected bearing in location, final assembling back and stressed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Embodiment
As shown in Figure 1, be the embodiment of the improved structure of rotating shaft of a kind of rotor of the utility model, comprise rotating shaft 1 and be installed on rotor 5 in the rotating shaft that described rotating shaft is provided with shaft shoulder structure 3 in the outside at Bearing Installation place 2.The end face of the described shaft shoulder is provided with chamfering 4.Described rotating shaft 1 with the cooperation place external diameter of rotor 5 on scribble the anaerobism glue-line.
Claims (3)
1. the improved structure of rotating shaft of a rotor comprises rotating shaft (1) and is installed on rotor (5) in the rotating shaft that it is characterized in that: described rotating shaft is provided with shaft shoulder structure (3) in the outside of Bearing Installation place (2).
2. the improved structure of rotating shaft of rotor according to claim 1, it is characterized in that: the end face of the described shaft shoulder is provided with chamfering (4).
