Description
Technical Field
The utility model relates to a front end cover of a generator.
Background
The generator comprises a base, a stator, a rotor shaft, a bearing and other electrical accessories. The front end cover mainly plays a role of encapsulating the motor and supporting and fixing the rotor in the dual bearing generator.
The front end cover of the current domestic or foreign generator comprises a circular cover plate 10, a cylindrical side wall 20 connected to the edge of the rear end face of the cover plate 10 and a front end cover flange 30 connected to the rear end of the side wall 20, wherein a plurality of air outlets are uniformly distributed along the circumference of the side wall 20 (see fig. 1a and 1 b). The front end cover has several obvious disadvantages, the structure is relatively complex relative to the function, and the structural characteristics cause the manufacturing process of the die to be complex and increase the manufacturing cost. Secondly, in the process of connecting the front end cover flange and the machine base front end flange by using the bolt, an installer needs to stretch hands into an air outlet of the front end cover for operation, the operation space is small, the installation difficulty is increased invisibly, and certain danger is realized.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide the front end cover of the generator, which can simplify the manufacturing process of a die on the premise of ensuring the structural strength and reduce the die cost and the iron consumption.
The purpose of the utility model is realized as follows: the front end cover of the generator comprises a circular ring-shaped cover plate, wherein,
a plurality of supporting claws with quadrangular frustum pyramid structures are uniformly arranged on the rear end surface of the cover plate along the circumference; two threaded blind holes are formed in the rear end face of each supporting claw, so that the centers of the threaded blind holes in the plurality of supporting claws and the center of the connecting hole in the flange at the front end of the base of the generator are positioned on the same circle.
In the front end cover of the generator, a reinforcing rib is further arranged between the inner end surface of each support claw and the rear end surface of the cover plate.
In the front end cover of the generator, the two side surfaces of each support claw and the rear end surface of the cover plate are in arc surface transition, and the outer end surface of each support claw is an arc surface.
The front end cover of the generator has the following characteristics:
1) the front end cover flange on the traditional structure is removed, the whole weight and the iron consumption of the front end cover are reduced, the manufacturing process of the die can be simplified, and the die cost is reduced.
2) A plurality of supporting claws extend backwards on the rear end face of the cover plate uniformly, and the supporting claws and the reinforcing ribs of the quadrangular frustum pyramid structure can improve the torsional strength of the front end cover and can also ensure the structural strength of the whole front end cover.
3) The threaded blind holes are formed in the rear end face of each supporting claw, so that bolts can be installed from the side of the engine base of the generator, installation space can be enlarged, accidents during installation can be reduced, and operation safety is improved.

Detailed Description
The utility model will be further explained with reference to the drawings.
Referring to fig. 2a and 2b, the front end cover of the generator of the present invention includes a circular cover plate 11, a plurality of support claws 12 with a quadrangular frustum pyramid structure are uniformly arranged on the rear end surface of the cover plate 11 along the circumference, a reinforcing rib 13 is further arranged between the inner side surface of each support claw 12 and the rear end surface of the cover plate 11, two side surfaces of each support claw 12 and the rear end surface of the cover plate 11 are in arc surface transition, and the outer end surface of each support claw 12 is an arc surface; two threaded blind holes 120 are formed in the rear end face of each support claw 12, so that the centers of the threaded blind holes 120 in the plurality of support claws 12 and the center of the connecting hole in the front end flange 40 of the generator base are positioned on the same circle.
According to the front end cover of the generator, the plurality of supporting claws 12 are uniformly and rearwardly extended from the rear end face of the cover plate 11, the supporting claws 12 and the reinforcing ribs 13 of the quadrangular frustum pyramid structure are arranged, so that the torsional strength can be improved, the structural strength of the whole front end cover 1 can be ensured, and meanwhile, the threaded blind hole 120 is formed in each supporting claw 12, so that the generator can be operated from the side of the generator base 4 (see figure 3) when the bolt 5 between the flange 40 at the front end of the generator base and the supporting claws 12 is installed, the operation space is enlarged, accidents in installation can be reduced, and the safety is improved. In addition, the space between adjacent support claws 12 can also form an air outlet. The number of the support claws 12 is preferably eight, and the outer dimension of each support claw 12 is such that the structural strength and the torsional strength of the front end cover are ensured.
According to the front end cover of the generator, a front end cover flange on the traditional structure is removed, the whole weight and the iron consumption of the front end cover can be reduced on the premise of ensuring the structural strength, the manufacturing process of a die can be simplified, and the die cost is reduced.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
