Abstract
The utility model relates to a motor fan structure which is provided with a check ring, does not need to be assembled with a check ring used by a shaft, and comprises a motor shaft and a fan. The fan is installed on the shaft extending part at the non-driving end of the motor shaft, and is driven to rotate by the motor shaft. The motor fan structure is characterized in that at least two cavities are arranged on the outer end surface of the fan; clamping pieces capable of expanding flexibly are formed between the cavities and the central hole of the fan; bayonets are arranged at the end parts of the clamping pieces and matched with the check ring on the motor shaft for fixing the fan; and overlapping pieces convenient for expanding the clamping pieces are arranged on the outer sides of the bayonets. With the motor fan structure, the structure is simple, smart and reasonable, the fan can be fixed on the motor shaft without adding the check ring used by the shaft, not only is the cooling effect of the fan retained, but also the cost of the check ring used by the shaft is saved, and the fan is simple and convenient to assemble and dissemble.
Description
Technical field
The utility model relates to motor from cooling off fan structure, specifically a kind ofly carries back-up ring and need not the motor ventilating fan structure of equipped shaft block ring.
Background technique
The stator coil of threephase asynchronous and rotor bar have the resistance effect, stator and rotor cores can generate heat when electrical power moves, each component temperature of motor raises, add the bearing high speed rotating and also can cause high temperature, these high temperature component all need in time to cool off, to guarantee the normal operation of motor.
In the prior art, it is the cooling of drying of fan that motor carries that the cooling of above-mentioned high temperature component mainly relies on, fan is installed in the shaft extension portion of motor shaft anti-drive end, and utilize shaft block ring to fix, rely on the rotation of motor shaft to drive the fan rotation, and then the drive gas flow, thereby play the cooling motor temperature action.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple, ingenious, reasonably carry the motor ventilating fan structure of back-up ring, it need not to add shaft block ring and fan can be fixed on the motor shaft, the cooling effect that had both kept fan, saved the shaft block ring cost again, fan loading and unloading simultaneously are simple and convenient.
According to the technological scheme that the utility model provides, a kind of motor ventilating fan structure that carries back-up ring comprises motor shaft and fan, and fan is installed in the shaft extension portion of motor shaft anti-drive end, by the motor shaft driven rotary; It is characterized in that: described fan has at least two cavitys on the exterior edge face, but is formed with the open fastener of elasticity between cavity and the fan center hole, is provided with bayonet socket in the end of fastener, and bayonet socket matches with circlip groove on the motor shaft, to fix fan; Have in the arranged outside of bayonet socket and to be convenient to the open lug of fastener.
As further improvement of the utility model, described fan employing has certain plasticity and flexible glass fiber reinforced polypropylene material is made.
As further improvement of the utility model, described at least two cavitys along the circumferential direction evenly distribute on the fan exterior edge face.
As further improvement of the utility model, described cavity and corresponding fastener are two.
As further improvement of the utility model, described motor shaft is provided with key, and described fan center hole inwall is provided with the groove that matches with key, and fan connects transmission by key with groove with motor shaft.
The utility model compared with prior art, advantage is: simple in structure, ingenious, reasonable, it need not to add shaft block ring and fan can be fixed on the motor shaft, has both kept the cooling effect of fan, saved the shaft block ring cost again, fan loading and unloading simultaneously are simple and convenient.

Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 5: the motor ventilating fan structure that carries back-up ring described in the utility model mainly is made up of motor shaft 1 and fan 2, fan 2 is installed in the shaft extension portion of motor shaft 1 anti-drive end, described motor shaft 1 is provided with key, described fan 2 center bore inner walls are provided with the groove 8 that matches with key, fan 2 connects transmission by key with groove 8 with motor shaft 1, and motor shaft 1 drives fan 2 rotations; Described fan has at least two cavitys 3 on 2 exterior edge faces, at least two cavitys 3 along the circumferential direction evenly distribute on fan 2 exterior edge faces, but be formed with the open fastener 4 of elasticity between cavity 3 and fan 2 center holes, cavity 3 in the present embodiment and corresponding fastener 4 are set to two; Be provided with bayonet socket 5 in the end of fastener 4, the diameter and the thickness of the circlip groove 6 on the diameter of bayonet socket 5 and thickness size and the motor shaft 1 are suitable, and bayonet socket 5 matches with circlip groove 6 on the motor shaft 1, to fix fan 2; Have in the arranged outside of bayonet socket 5 and to be convenient to fastener 4 open lugs 7.
Fan 2 preferred employings in the utility model have certain plasticity and flexible glass fiber reinforced polypropylene material is made.
Installation process of the present utility model is as follows:
Adjust fan 2 and motor shaft 1 position, the key on the motor shaft 1 is aimed at the groove 8 on fan 2 center bore inner walls; Fan 2 is enclosed within on the motor shaft 1, uses special tool that the lug 7 of bayonet socket 5 outsides is outwards opened, because fastener 4 outsides are cavitys 3, cavity 3 can make fastener 4 can outwards open being subjected to external force to do the time spent; When fastener 4 is flared to a certain degree, bayonet socket 5 can not stop motor shaft 1 again, motor shaft 1 can insert in fan 2 center holes smoothly, after fan 2 is in place, take down special tool, the suffered external force of fastener 4 disappear, and fastener 4 resets and embeds in the circlip groove 6 on the motor shaft 1, and fastener 4 has promptly played the effect of original shaft block ring at this moment.Motor shaft 1 drives fan 2 rotations when rotating, thereby plays the cooling effect to motor.
