Abstract
The utility model discloses an output shaft and an asynchronous motor thereof, which comprises an slender shaft body, wherein one side of the slender shaft body is provided with a long key groove in the axial direction, the output end of the slender shaft body is provided with a threaded part, and the threaded part is provided with a short key groove corresponding to the long key groove.
Description
Technical Field
The utility model relates to the technical field of machinery, in particular to an output shaft and an asynchronous motor thereof.
Background
The application range of the asynchronous motor is wide, the application range of the asynchronous motor is in the field of crushers, the shaft body of an output shaft of the asynchronous motor used in the field of crushers at present is short, the torque value and the load strength are low, the crushing of materials cannot be well met, in addition, the shaft body of the output shaft is short and is not beneficial to well fixing with the crushers, and in order to solve the problem, the utility model discloses the output shaft and the asynchronous motor thereof.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model discloses an output shaft and an asynchronous motor thereof.
In order to achieve the above purpose, the present utility model is realized by the following technical scheme: an output shaft comprises an slender shaft body, one side of the slender shaft body is provided with a long key groove in the axial direction, the output end of the slender shaft body is provided with a threaded portion, and the threaded portion is provided with a short key groove corresponding to the long key groove.
Further, the end face of the output tail end of the slender shaft body is provided with a locking tooth hole.
Further, the center line of the long key groove and the center line of the short key groove are in the same straight line.
An asynchronous motor comprising the output shaft.
The utility model has the following beneficial effects:
1. the utility model can increase the output torque and load strength of the asynchronous motor by increasing the length of the output shaft, and compared with the traditional asynchronous motor, the output shaft performance of the asynchronous motor is enhanced.
2. The long key groove, the short key groove and the thread structure are arranged on the outer surface of the output shaft, so that the pulverizer can be stably installed with other parts of the pulverizer, and the practicability is high.

FIG. 1 is a schematic diagram of the overall structure of the present disclosure;
FIG. 2 is a schematic view of an axial cross-sectional structure of the present disclosure;
fig. 3 is a schematic structural diagram of an asynchronous motor according to the present disclosure.
In the figure: 10. an elongated shaft body; 20. a long key slot; 30. a threaded portion; 40. a short key slot; 50. locking the tooth holes; 60. an asynchronous motor.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Example 1
Referring to fig. 1 and 2, an output shaft includes an elongated shaft body 10, one side of the elongated shaft body 10 is provided with a long key slot 20 in an axial direction thereof, an output end of the elongated shaft body 10 is provided with a threaded portion 30, the threaded portion 30 is provided with a short key slot 40 corresponding to the long key slot 20, and the outer surface of the elongated shaft body 10 is provided with the long key slot 20, the short key slot 40 and a threaded structure which can be stably mounted with other parts of a pulverizer, so that the practicability is higher; in addition, in order to ensure that the long key groove 20 and the short key groove 40 are symmetrically distributed according to the central line, teeth or other connecting pieces included in the pulverizer are convenient to correctly assemble, and the stress is uniform during operation; the center line of the long key groove 20 and the center line of the short key groove 40 are in the same straight line.
Referring to fig. 1 and 2, as a preferred mode of the present utility model, the output end face of the slender shaft body 10 is provided with a locking tooth hole 50, so that a shaft sleeve matched with the pulverizer can be better fixed.
Example two
The second embodiment of the present utility model is implemented based on the second embodiment;
referring to fig. 3, an asynchronous motor 60 including the above-described output shaft is provided, and the length of the output shaft is increased to increase the output torque and load strength of the asynchronous motor 60, as compared with the conventional asynchronous motor 60, the output shaft performance is enhanced.
The foregoing embodiments are merely illustrative of the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and to implement the same according to the present utility model, not to limit the scope of the present utility model. All changes and modifications that come within the meaning and range of equivalency of the utility model are to be embraced within their scope.
