Description

Waterproof motor structure

Technical Field

The utility model relates to an electric machine structure especially relates to a waterproof electric machine structure that water-proof effects is good, and it belongs to the motor field.

Background

The existing motor shaft outlet end is not provided with a waterproof structure, or a shell and an end cover are adopted to arrange the motor in the shell for waterproofing, the process and assembly errors are poor, the waterproof effect is poor, the service life of a product is influenced, and water permeates into the motor to cause unnecessary potential safety hazards.

The waterproof application range of some motors in addition has little limitation, can not use in abominable environment, and if this motor is applied to moist operational environment, inside water or the dust in the air got into the motor easily, lead to inside spare part of motor to appear corroding, reduced the life of motor, brought very big inconvenience for the user.

The chinese patent publication No. CN211089287U, published as 24/07/2020, discloses a utility model named "a waterproof motor". This patent includes the casing, the cover, one side fixedly connected with sealing washer of casing, one side and the cover of sealing washer contact, two fixed slots have been seted up to one side of casing, the mounting groove has all been seted up on the one side inner wall that two fixed slots are close to each other, two recesses have been seted up to one side of cover, equal slidable mounting has the fixed plate in two recesses, fixed plate movable mounting is in the fixed slot that corresponds, the equal fixed mounting in one side that two fixed plates are close to each other has the mount pad, mount pad and the mounting groove looks adaptation that corresponds, threaded hole has all been seted up to one side of two fixed plates. Although the waterproof motor has a flexible structure and is convenient to assemble and disassemble, the motor is opened in maintenance, so that time and labor are saved; but the waterproof effect is general, only one-way sealing can be realized, and the waterproof structure cannot be applied to severe environments.

Therefore, the waterproof motor structure which is simple and reasonable in structural design, good in waterproof effect and capable of being applied to severe environments is particularly necessary.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a structural design simple reasonable, safe and reliable, water-proof effects is good, the wide waterproof motor structure of range of application.

The utility model provides a technical scheme that above-mentioned problem adopted is: this waterproof motor structure, including motor body, pivot, bearing one, bearing two, rotor and motor end cover, motor body and rotor phase-match are fixed through the motor end cover, are provided with pivot, bearing one and bearing two on the rotor, its characterized in that: the motor end cover is characterized by further comprising a first sealing ring and a second sealing ring, wherein the first sealing ring is arranged on the motor end cover, the first sealing ring is arranged on the inner side of the motor end cover, and the second sealing ring is arranged on the outer side of the motor end cover; the outer side prevents water from leaking outside by tightly matching the sealing ring II; the inner side prevents water from flowing into the motor by using the tight fit of the sealing ring.

Preferably, the utility model discloses still include to separate and keep off the piece, it links to each other with the motor end cover to separate the piece.

Preferably, the utility model discloses still include bearing one and bearing two, be provided with bearing one and bearing two on the rotor.

Preferably, the first sealing ring is arranged between the motor end cover and the rotating shaft.

Preferably, the second sealing ring is arranged between the motor end cover and the blocking piece.

Preferably, the first sealing ring and the second sealing ring of the utility model are both made of rubber; the barrier is made of plastic.

Compared with the prior art, the utility model, have following advantage and effect: overall structure design is simple reasonable, safe and reliable, separates to keep off the piece and prevents the infiltration of motor outside for sealing washer two reaches sealed effect, and sealing washer one is inboard sealed, and above-mentioned double seal structure makes water-proof effects better, long service life, and the range of application of this motor structure is wide, also can carry on waterproofly in the adverse circumstances, satisfies different user demands.
