Description
Technical field
The utility model relates to a kind of motor, especially anti-bias tyre fire-proof motor.
Background technology
Along with the deep propelling of energy-saving and emission-reduction, increasing variable-frequency motor is applied to needs explosion-proof place, demand for explosion-proof air-cooler is wherein increasing, fire-proof motor of the prior art is owing to having influence on the job stability of motor because rotor, when rotating, slight skew may occur, increase noise, also can have influence on the useful life of motor.
Utility model content
In order to overcome the deficiency that existing motor easily offsets, the utility model provides anti-bias tyre fire-proof motor.
The utility model solves the technical scheme that its technical problem adopts: anti-bias tyre fire-proof motor, comprise casing, stator, rotor and front end housing, rotor is movably connected in stator, front end housing is fixed on casing front end, rotor is arranged with ball bearing, ball bearing bottom has been welded to connect reinforced pole, and reinforced pole tail end is fixedly connected on extension rod, and one end of extension rod is welded to connect on chassis base.
According to another embodiment of the present utility model, comprise reinforced pole tail end further and be provided with retainer ring, extension rod is provided with fixing hole, and extension rod is placed in retainer ring, and is fixedly connected with reinforced pole by latch.
According to another embodiment of the present utility model, comprise ball bearing outer wall further and be bonded with silicone grease layer, fixing hole quantity is two or more.
The beneficial effects of the utility model are, this motor can prevent rotor word time rotational from offseting, and decreases noise, extends useful life, saved cost, improve effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. casings, 2. stator, 3. rotor, 4. front end housing, 5. ball bearing, 6. reinforced pole, 7. extension rod, 8. retainer ring, 9. fixing hole, 10. latch in figure, 11. silicone grease layers.
Embodiment
If Fig. 1 is structural representation of the present utility model, anti-bias tyre fire-proof motor, comprise casing 1, stator 2, rotor 3 and front end housing 4, rotor 3 is movably connected in stator 2, front end housing 4 is fixed on casing 1 front end, rotor 3 is arranged with ball bearing 5, ball bearing 5 bottom has been welded to connect reinforced pole 6, reinforced pole 6 tail end is fixedly connected on extension rod 7, one end of extension rod 7 is welded to connect on casing 1 base, reinforced pole 6 tail end is provided with retainer ring 8, extension rod 7 is provided with fixing hole 9, extension rod 7 is placed in retainer ring 8, and be fixedly connected with reinforced pole 6 by latch 10, ball bearing 5 outer wall is bonded with silicone grease layer 11, fixing hole 9 quantity is two or more.
First ball bearing 5 is set on rotor 3, then the retainer ring 8 of reinforced pole 6 bottom is set on extension rod 7, after adjusting the position of ball bearing 5 on rotor 3, finally latch 10 is utilized to be fixed up the fixing hole 9 that retainer ring 8 is aimed on extension rod 7, like this when rotor 3 rotates time due to the fixation of reinforced pole 6, can prevent it from offseting, and the silicone grease layer 11 on ball bearing 5 can dispel the heat to rotor 3, this motor can prevent rotor word time rotational from offseting, decrease noise, extend useful life, save cost, improve effect.
