Description

Combined novel end cover

Technical Field

The utility model relates to an automobile parts field especially relates to generator end cover.

Background

The motor end cover is the lid of motor housing, generally divides protecgulum and hou gai two parts, and the main function is exactly to be used for fixing and supporting motor shaft, and the material of motor end cover all is the metal material generally, including aluminium, aluminium cast, cold punching steel, plastics, bakelite, chooses for use different materials according to different motor types, if the automobile motor is the cold punching steel mostly, large-scale motor all uses the die casting technology.

For the motor requiring cooling air circulation, the end cover is provided with ventilation openings in various shapes, so that the heat dissipation of the motor is facilitated, the service life of the motor is prolonged, but dirt and moisture enter the motor when air is circulated through the ventilation openings, so that the motor is failed or damaged, in the aspect of motor maintenance, the integral structure of the existing end cover is not beneficial to the disassembly and maintenance of the motor, and meanwhile, the frequency of motor failure is increased due to the fact that no dustproof device is arranged.

SUMMERY OF THE UTILITY MODEL

In view of the defects existing in the prior art, the utility model provides a novel combined end cover, which comprises an end cover body and a dustproof device; the end cover is characterized in that the end cover is disc-shaped, the disc is formed by splicing an end cover body and a dustproof device, the sector area formed by the dustproof device is smaller than that of the end cover body, and the end cover body and the dustproof device are detachably connected through bolts; and the dustproof device is provided with a screen.

Preferably, two bolt installation seats are arranged on the outer side of the outer collar, and the end cover body and the dustproof device are assembled and connected through the two bolt installation seats.

Preferably, the outer side of the outer clamping ring is further provided with four mounting seats and a threaded hole, and the four mounting seats are evenly distributed.

Preferably, the inner side of the outer clamping ring is provided with a reinforcing rib.

Preferably, the mounting seat, the bolt mounting seat, the inner collar, the shaft groove, the reinforcing rib and the ventilation opening are all integrally formed.

Preferably, the last retainer plate that is provided with of dust keeper, be provided with the buckle on the inner edge of retainer plate, the retainer plate has the screen cloth through the buckle joint.

Compared with the prior art, the utility model discloses following beneficial effect has:

dustproof device can reduce the motor because of the trouble emergence frequency that foreign matters such as dust arouse, dustproof device can change the screen cloth of different specifications in order to adapt to the different operational environment of motor simultaneously, the concatenation formula end cover can demolish half circle part end cover through adjusting bolt when motor trouble and can inspect and maintain, it is loaded down with trivial details to avoid traditional end cover whole demolishs to bring, the concatenation formula end cover can control the fit-up gap through adjusting bolt and come the better stable motor operation, it is not high to process dimensional tolerance requirement, reduce the cost that precision finishing brought.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1-2, a novel combined end cap comprises an end cap body and a dustproof device; the end cover is characterized in that the end cover is disc-shaped, the disc is formed by splicing an end cover body and a dustproof device, the sector area formed by the dustproof device is smaller than that of the end cover body, and the end cover body is detachably connected with the dustproof device through bolts; the dustproof device is provided with a fixed ring 10, a buckle is arranged on the inner edge of the fixed ring 10, and the fixed ring 10 is clamped with a screen 11 through the buckle; the mounting seat 1, the bolt mounting seat 2, the inner clamping ring 6, the shaft groove 9, the reinforcing ribs 7 and the ventilation openings 8 are all integrally formed. The number of the mounting seats 1 arranged on the outer side of the outer clamping ring 5 is four, and a threaded hole 12 is further formed in the mounting seats 1, and the four mounting seats 1 are uniformly distributed; the threaded hole 12 is used for connecting and fixing the motor and the end cover.

The principle of the utility model is as follows; the motor and other parts are installed on the end cover of the main body part with the inner clamping ring 6, the motor and other parts are supported and fixed, the end cover of the part with the dustproof device is fixedly connected with the fixing ring 10 for the dustproof device through a buckle, and the end cover is used for disassembling, maintaining and cleaning the motor and other parts when the motor and other parts have faults and replacing the screen meshes 11 with different specifications.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the right of the present invention should not be limited thereby, and therefore, modifications, equivalent changes, improvements, etc. made in the claims of the present invention are still included in the scope of the present invention.
