Abstract
The utility model relates to a motor lantern ring structure, especially to a lantern ring which possesses a lantern ring body (1), a lantern ring inner circle (2) and a rotating shaft (3) in connection with the lantern ring inner circle (2). The rotating shaft (3) comprises rotating shaft spoke ribs (31) which are in interference connection with the lantern ring inner circle (2). The lantern ring inner circle (2) between each two rotating shaft spoke ribs is provided with a concave part (21). The fit positions between the lantern ring inner circle and the rotating shaft spoke ribs also employ interference connection; another six parts without contact with the spoke ribs are provided with concave parts such that the area of an air course only going between the spoke ribs originally is substantially increased, and the air course of the utility model is more smooth compared with an original air course, which can reduce the temperature rise of a motor.
Description
Technical field
The utility model relates to a kind of motor thimble structure, relates in particular to a kind of collar.
Background technology
At present, in the existing thimble structure, the place that the collar is connected with rotating shaft is a full circle, and the general collar and rotating shaft interference fit prevent that motor rotor copper bar in high speed rotating from producing loosening.
The utility model content
The purpose of the utility model provides and can prevent motor in the time of high speed rotating, the tight a kind of collar of rotor copper bar.
The purpose of the utility model realizes as follows: a kind of collar; Have circle in the collar body and the collar with the said collar in the rotating shaft that is connected of circle; Said rotating shaft comprises rotating shaft spoke muscle; Interior the justifying of the said collar is connected with the interference of said rotating shaft spoke muscle, justifies being provided with concave part between the rotating shaft spoke muscle in the above collar in twos.
Saying further, said rotating shaft spoke muscle has 6.
The advantage of the utility model: interference fit is still adopted in spoke muscle cooperation place in interior circle of the collar and the rotating shaft; Other does not contact six equal recessings in position of spoke muscle; Make former can only increasing greatly through the wind path area between the spoke muscle, more unobstructed than former design wind path, reduced the temperature rise of motor.
Description of drawings
For content of the present invention is expressly understood more easily, below according to instantiation, and combine accompanying drawing that the present invention is done further detailed explanation, wherein:
Accompanying drawing is the structural representation of the utility model;
Embodiment:
See accompanying drawing; A kind of collar; Have circle 2 in the collar body 1 and the collar with the said collar in the rotating shaft 3 that is connected of circle 2; Said rotating shaft 3 comprises six rotating shaft spoke muscle 31, and circle 2 is connected with 31 interference of said rotating shaft spoke muscle in the said collar, between two rotating shaft spoke muscle, justifies 2 in the above collar and is provided with concave part 21.
Above-described instantiation; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the instantiation of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. collar, have circle (2) in the collar body (1) and the collar with the said collar in the rotating shaft (3) that is connected of circle (2); It is characterized in that: said rotating shaft (3) comprises rotating shaft spoke muscle (31), and circle (2) is connected with said rotating shaft spoke muscle (31) interference in the said collar, is provided with concave part (21) justifying (2) between the rotating shaft spoke muscle in the above collar in twos.
2. according to the said a kind of collar of claim 1, it is characterized in that: said rotating shaft spoke muscle has 6.
