Abstract
The present invention relates to a kind of axle sleeve for rotor, including a sleeve body, the center of sleeve body is provided with through hole；One limit body, limit body includes the stopper slot for being placed in the setting of sleeve body upper side equal circumference, and stopper slot is recessed to the axle center of sleeve body to be set, and the inner side end of stopper slot is the convex structure that opening is set outwardly, a diameter of 2.5mm of stopper slot, the height of stopper slot is 1cm 1.5cm.The present invention has the advantages of simple in construction, to ensure the connection reliability between axle sleeve and electric machine casing.
Description
Technical field：
The present invention relates to a kind of axle sleeve for rotor.
Background technology：
The axle sleeve of rotor of the prior art is all to be fixed by being molded or being interference fitted with electric machine casing, and blower fan electronics
Operating mode it is typically all relatively severe, after long-term use of, axle sleeve easily loosens with electric machine casing, then occur axle sleeve with
Axis of rotation, bring it is bigger rock and noise, have impact on the service life of blower fan.
The content of the invention：
The invention aims to overcome the shortcomings of the above, there is provided and it is a kind of simple in construction, ensure between axle sleeve and electric machine casing
Connection reliability the axle sleeve for rotor.
The purpose of the present invention is achieved through the following technical solutions：A kind of axle sleeve for rotor, including
One sleeve body, the center of sleeve body are provided with through hole；
One limit body, limit body include the stopper slot for being placed in the setting of sleeve body upper side equal circumference, and stopper slot is to axle sleeve sheet
The axle center depression of body is set, and the inner side end of stopper slot is the convex structure that opening is set outwardly.
Further improvement of the present invention is：A diameter of 2.5mm of stopper slot, the height of stopper slot is 1cm-1.5cm.
The present invention has advantages below compared with prior art：The limit body of the present invention, which can place axle sleeve, to be occurred circumferentially
Rotation, then between axle sleeve and housing occur loosen after, be not in the situation that axle sleeve follows axis of rotation, improve axle
Connection reliability between set and housing, avoids shadow of the problem of axle sleeve is connected with housing to the stationarity of whole motor operation
Ring, be advantageous to the extension of the stationarity and service life of motor operation.
Brief description of the drawings：
Fig. 1 is a kind of structural representation of axle sleeve for rotor of the invention.
Embodiment：
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, the implementation
Example is only used for explaining the present invention, is not intended to limit the scope of the present invention..
A kind of axle sleeve for rotor of the present embodiment, as shown in figure 1, including
One sleeve body 1, the center of sleeve body 1 are provided with through hole 3；
One limit body, limit body include the stopper slot 2 for being placed in the setting of the upper side equal circumference of sleeve body 1, and stopper slot 2 is to axle sleeve
The axle center depression of body 1 is set, and the inner side end of stopper slot 2 is the convex structure that opening is set outwardly.
A diameter of 2.5mm of stopper slot 2, the height of stopper slot 2 is 1cm-1.5cm.
The limit body of the present invention can place axle sleeve and circumferential rotation occurs, then be loosened between axle sleeve and housing
Afterwards, be not in situation that axle sleeve follows axis of rotation, improve the connection reliability between axle sleeve and housing, avoid axle sleeve
Influence of the problem of being connected with housing to the stationarity of whole motor operation, be advantageous to the stationarity and service life of motor operation
Extension.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
Merely illustrating the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also have
Various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention
By appended claims and its equivalent thereof.
