Description
Technical field
The present invention relates to motor seal technical field, more particularly to a kind of sealing device of dust explosion-proof motor.
Background technology
Motor using relatively broad, makes in fields such as machinery productions for some in the more factory of special occasions such as dust
Motor, i.e. dust explosion-proof motor, motor will accomplish sealing protection to prevent dust from entering motor internal and explode, and make
Into the injures and deaths of personnel, the sealing effectiveness of dust explosion-proof motor present in prior art is poor, certain potential safety hazard be present.
The content of the invention
The purpose of the present invention is the defects of overcoming prior art to exist, there is provided a kind of preferable dust explosion protection electricity of sealing effectiveness
The sealing device of machine.
The technical solution adopted for the present invention to solve the technical problems is：A kind of sealing device of dust explosion-proof motor, bag
Include the first sealing ring, the first sealing ring is arranged at the counterface between the end cap of motor and support, in addition to dust ring and
Outside framework oil seal, dust ring and outside framework oil seal are set in the periphery of motor shaft and are fitted close with bearing end cover, the outlet in motor
Arranged between box mounting seat and outlet cassette holder, between outlet cassette holder and wiring bucket and between outlet cassette holder and wire outlet box cover
Sealing ring.
Beneficial effect：In the present invention, encapsulation process is carried out to several main places for easily entering dust of motor, including
The sealing at following position：Firstth, it is close to being carried out between the end cap 20 and support 30 of motor by using the first sealing ring 10
Envelope；Secondth, bearing chamber is sealed by dust ring 40 and outside framework oil seal 50；3rd：Outlet box is installed by sealing ring
Between seat 70 and outlet cassette holder 80, between outlet cassette holder 80 and wiring bucket 90 and between outlet cassette holder 80 and wire outlet box cover 100
Sealed, the sealing effectiveness of so whole motor is preferable.

Embodiment
With reference to Fig. 1-Fig. 4, the invention will be further described.
A kind of sealing device of dust explosion-proof motor, including the first sealing ring 10, the first sealing ring 10 are arranged in motor
At counterface between end cap 20 and support 30, in addition to dust ring 40 and outside framework oil seal 50, dust ring 40 and outside framework oil seal
50 are set in the periphery of motor shaft 1 and are fitted close with bearing end cover 60, outlet box mounting seat 70 and outlet cassette holder in motor
Sealing ring is arranged between 80, between outlet cassette holder 80 and wiring bucket 90 and between outlet cassette holder 80 and wire outlet box cover 100.
In the present invention, several main places for easily entering dust of motor are carried out with encapsulation process, including following position is close
Envelope：Firstth, by using the first sealing ring 10 to being sealed between the end cap 20 and support 30 of motor；Secondth, by dust-proof
Ring 40 and outside framework oil seal 50 seal to bearing chamber；3rd：By sealing ring to outlet box mounting seat 70 and outlet cassette holder 80
Between, sealed between outlet cassette holder 80 and wiring bucket 90 and between outlet cassette holder 80 and wire outlet box cover 100, it is so whole
The sealing effectiveness of individual motor is preferable, effectively prevents dust etc. from entering motor, eliminates safe hidden trouble.
As further preferred scheme：Fixation is connected by screw between the end cap 20 and support 30 of the motor, and
The screwed hole of screw connection is the blind hole being opened on support 30, is designed to that blind hole can avoid dust from screw connection
Enter in hole in motor.
Preferably：Between outlet box mounting seat 70 and outlet cassette holder 80 in the motor, outlet cassette holder 80 and wiring bucket
Fixation, and the spiral shell used in screw connection are connected by screw between 90 and between outlet cassette holder 80 and wire outlet box cover 100
Pit is blind hole, likewise, being designed to that blind hole can avoid dust from entering out of screw connection hole in motor.
It should be appreciated that specific embodiment described above is only used for explaining the present invention, it is not intended to limit the present invention.By
Among the obvious changes or variations that the spirit of the present invention is extended out is still in protection scope of the present invention.
