Description

Dustproof motor end cover

Technical Field

The utility model belongs to the technical field of the motor accessory technique and specifically relates to a dustproof motor end cover.

Background

The end cover is a rear cover arranged behind the motor and other machine cases, and the quality of the motor is directly influenced if the end cover is good or bad. The existing end cover realizes the internal heat dissipation of the motor by a mode of arranging a through hole on the cover plate, but the radiating hole is not provided with a matched dustproof device, the matching tightness of the cover plate and the motor shell is not good, and dust accumulation is caused, so that the performance and the service life of the motor are influenced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of current end cover not possessing dustproof function, the utility model provides a dustproof motor end cover separates cotton and solves the problem through setting up in the apron.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a dustproof motor end cover, includes that the outer fringe evenly is provided with the apron of mount pad, and the medial surface of apron is provided with dustproof cotton that separates, and dustproof medial surface that separates cotton is provided with and is used for separating cotton fixed pressure strip, corresponds on pressure strip and the apron and has seted up the louvre, and the medial surface of mount pad still is provided with and is used for the tight tighrening ring of sealed.

Furthermore, the pressure strip and the cover plate are connected in a threaded mode, external threads are arranged on the outer edge of the pressure strip, and internal threads are correspondingly arranged on the inner wall of the cover plate.

Furthermore, at least four reinforcing ribs are uniformly arranged above the pressing plate by taking the center of the cover plate as the circle center.

Further, the fastening ring includes the collar of welded fastening at the apron inner wall and sets up the outside cylindricality rubber strip at the collar.

Furthermore, the cross section of the mounting ring is L-shaped, and the cylindrical rubber strips are fixed on the mounting ring at equal intervals.

The utility model has the advantages that the dustproof cotton is arranged on the inner side of the existing cover plate, so that the interior of the motor is prevented from being dustproof under the condition that the heat dissipation of the motor is not influenced; the fastening ring arranged on the cover plate not only enhances the connection strength of the end cover and the motor shell, but also seals the connection surface of the end cover and the motor shell, and avoids dust from entering the motor.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic view of the present invention with the fastening ring removed;

FIG. 2 is a schematic view of a fastening ring of the present invention;

fig. 3 is a schematic view of the plane a-a in fig. 2.

In the figure, 1, a cover plate, 2, a mounting seat, 3, dustproof and cotton-proof layers, 4, a pressure plate, 5, heat dissipation holes, 6, reinforcing ribs, 7, a mounting ring and 8, cylindrical rubber strips are arranged.

Detailed Description

Fig. 1 is the utility model discloses a structural schematic diagram, a dustproof motor end cover, evenly be provided with apron 1 of mount pad 2 including the outer fringe, the medial surface of apron 1 is provided with dustproof cotton 3 that separates, and the medial surface that dustproof cotton 3 that separates is provided with and is used for separating cotton fixed pressure strip 4, and the louvre 5 has been seted up to corresponding on pressure strip 4 and the apron 1, and the medial surface of mount pad 2 still is provided with and is used for sealed tighrening ring.

During the use, will prevent dust and separate cotton 3 and lay at 1 medial surface of apron, then press the pressure strip 4 lid and fix on preventing dust separates cotton 3, then establish motor casing tip with whole end cover, accomplish the installation, the dust that the louvre 5 that corresponds to seting up on apron 1 and the pressure strip 4 produced at the heat dissipation in-process is pressed from both sides the dustproof cotton 3 absorption that separates of establishing the middle part to avoid the dust to pile up, guarantee the normal use of motor.

The pressure strip 4 and the cover plate 1 are connected in a threaded mode, the outer edge of the pressure strip 4 is provided with external threads, the inner wall of the cover plate 1 is correspondingly provided with internal threads, and the pressure strip 4 and the cover plate 1 are detachably connected in a threaded mode.

At least four reinforcing ribs 6 are uniformly arranged above the pressing plate 4 by taking the center of the cover plate 1 as the circle center, the reinforcing ribs 6 are welded and fixed on the pressing plate 4, and the reinforcing ribs 6 are triangular and have high supporting strength.

As shown in fig. 2, the fastening ring comprises a mounting ring 7 fixed on the inner wall of the cover plate 1 by welding and a cylindrical rubber strip 8 arranged outside the mounting ring 7, wherein the cylindrical rubber strip 8 is fixedly arranged on the bottom plate of the mounting ring 7 and is circumferentially distributed on the outer wall of the mounting ring 7.

As shown in fig. 3, the cross section of the mounting ring 7 is L-shaped, and the cylindrical rubber strips 8 are arranged on the mounting ring 7 at equal intervals. 7 welded fastening of collar 7 is at the medial surface of mount pad 2, and the bottom surface of collar 7 flushes with the upper surface of mount pad 2, and cylindricality rubber strip 8 flushes through strong adhesive paste at the outer wall of collar 7, and the lateral surface of cylindricality rubber strip 8 and 1 inner wall of apron.

During the use, establish at the motor casing tip with apron 1 lid, in the collar 7 on the apron 1 terminal surface inserted the motor casing, cylindricality rubber strip 8 closely laminates with the motor casing inner wall, carries out the outrigger and seals to avoid the dust to get into inside the motor.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
