Technical field
This utility model relates to a kind of motor, particularly relates to a kind of industrial vehicle fire-proof motor.
Background technology
Motor refers to a kind of calutron realizing electric energy conversion or transmission according to the law of electromagnetic induction.Its Main Function is to produce driving torque, and therefore motor is mainly used in the every field such as colliery, metallurgy, petroleum gas, petrochemical industry, weaving, town gas, traffic, grain and oil processing, papermaking, medicine, oil fuel filling station.
At present, needing motor to possess explosion-proof at some special occasions avoids motor to occur unnecessary security incident in use, and existing motor explosion-proof performance is all poor, simultaneously when motor be in the place that some are moist or dust is many be operated time, conventional motor is due to poor sealing, protection deficiency, easily occur that motor internal easily enters dust or steam, and then cause motor damage and safety problem.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of industrial vehicle fire-proof motor.
This utility model is achieved through the following technical solutions:
Industrial vehicle fire-proof motor, including casing and the rotor being positioned at casing, described casing one end has drive end end cap, the other end has non-drive end shield, it is arranged with stator coil outside described rotor, outside described casing, there is cable entry, described cable entry surface has flame proof thread, described rotor side is connected with described drive end end cap by the first deep groove ball bearing, described rotor opposite side is connected with described non-drive end shield by the second deep groove ball bearing, has spring shim between described second deep groove ball bearing and non-drive end shield.
Described a kind of industrial vehicle fire-proof motor, described rotor one end is provided with copper sheathing, and described copper sheathing is set in outside the first deep groove ball bearing, contacts with described drive end end cap.
Described a kind of industrial vehicle fire-proof motor, the radial clearance≤0.2mm between described rotor and drive end end cap, faying face length >=12.5mm.
Described a kind of industrial vehicle fire-proof motor, is additionally provided with oil sealing between described first deep groove ball bearing and drive end end cap.
Described a kind of industrial vehicle fire-proof motor, described casing and drive end end cap, casing all adopt mode that the mode of threaded engagement, plane formula engage or seam faying face to coordinate with non-drive end shield, are bolted fastening.
Described a kind of industrial vehicle fire-proof motor, the described rotor other end is provided with axle snap ring.
The beneficial effect that this utility model reaches:
Fire-proof motor of the present utility model makes motor by arranging the flame proof thread on cable entry surface, possesses good explosion-proof, arranges spring shim simultaneously and prevent rotor from axially moving.
After explosion-proof motor shell of the present utility model and parts polish thereof, carrying out the water pressure test, test pressure is 1.5MPa, lasts and is not less than 10s, ne-leakage and without permanent deformation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
In figure: 1, drive end end cap, 2, casing, 3, non-drive end shield, 4, the first deep groove ball bearing, 5, rotor, 6, copper sheathing, 7, the second deep groove ball bearing, 8, spring shim, 9, velocity response dish, 10, flame proof thread, 11, stator coil, 12, cable entry, 13, oil sealing, 14, axle snap ring, 15, radial clearance.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.Following example are only for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As shown in the figure, industrial vehicle fire-proof motor of the present utility model, including casing 2 and the rotor 5 being positioned at casing 2, described casing 2 one end has drive end end cap 1, the other end has non-drive end shield 3, it is arranged with stator coil 11 outside described rotor 5, outside described casing 2, there is cable entry 12, described cable entry 12 surface has flame proof thread 10, described casing 2 surface also has flame proof thread, described rotor 5 side is connected with described drive end end cap 1 by the first deep groove ball bearing 4, described rotor 5 opposite side is connected with described non-drive end shield 3 by the second deep groove ball bearing 7, between described second deep groove ball bearing 7 and non-drive end shield 3, there is spring shim 8.Described casing 2, stator coil 11, rotor 5 and drive end end cap 1 and non-drive end shield 3 adopt high-quality mild steel polish to form.
Specifically, the place that casing 2 surface, cable entry 12 surface contact with flame proof thread 10 is screw-like, increases passage of flame, improves explosion-proof effect.
Described rotor 5 one end is provided with copper sheathing 6, and described copper sheathing 6 is set in outside the first deep groove ball bearing 4, contacts with described drive end end cap 1.Radial clearance 15≤0.2mm between described rotor 5 and drive end end cap 1, faying face length >=12.5mm.By limiting radial clearance and faying face length, when explosive mixture invades inside it, when blasting because of certain reason, the explosive mixture outside flameproof enclosure will not be caused to explode, it is ensured that explosion insulation performance.
It is additionally provided with oil sealing 13 between described first deep groove ball bearing 4 and drive end end cap 1.
Described casing 2 and drive end end cap 1, casing 1 all adopt mode that the mode of threaded engagement, plane formula engage or seam faying face to coordinate with non-drive end shield 3, are bolted fastening.
Described rotor 5 other end is provided with axle snap ring 14 and velocity response dish 9.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
