Description
Technical Field
The utility model relates to a motor manufacturing field especially relates to a non-drive end cover structure of generator.
Background
The motor is difficult to start in use, because when the generator starts a motor load, the motor can normally work only by 6-7 times of rated current when being started, and when the voltage of the main generator terminal is reduced at the moment of starting, the power supply of the automatic regulator is reduced, so that the input energy of the automatic voltage regulator is insufficient to provide exciting current, and the starting is difficult. Therefore, it is desirable to improve the starting performance by providing an additional exciting means to supply a required exciting current.
However, in the process of providing an additional excitation device, the fixing frame can only be installed on the existing generator housing by welding or punching, damage to the generator can be caused, and the installation is inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a generator non-drive end cover structure reforms transform through the end cover to traditional motor to need when additionally exciting arrangement is installed in preparation for.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a non-drive end cover structure of generator, it includes the end cover body, the pivot hole has been seted up on the end cover body, the inboard of end cover body is provided with bearing frame and internal fixation post, the bearing frame is located the periphery in pivot hole, a swivel bearing for the installation is fixed and support pivot, a plurality of internal fixation post circumference equipartitions are in the periphery of bearing frame, be used for installing generator stator assembly, the outside of end cover body is provided with external fixation post and boss, a plurality of external fixation post circumference equipartitions are in the periphery in pivot hole, be used for installing extra excitation device, the boss is located the periphery of each external fixation post, install the protection casing that is used for coveing external fixation post and.
Particularly, the bearing seat, the inner fixing column and the outer fixing column are integrally formed by the end cover body.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, the non-drive end cover structure of generator is used for replacing current end cover, makes the end cover except can fixing and supporting motor shaft, can also install the inside stator assembly of motor to and reserve the fixed part that has the extra excitation device of installation, use when supplying needs, be expected to become motor standard and push market, compact structure, simple to operate, functional good.

Detailed Description
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.
Please refer to fig. 1 to 3, the embodiment provides a non-driving end cover structure of a generator, which includes an end cover body 1, a rotating shaft hole 2 is formed on the end cover body 1, a bearing seat 3 and an inner fixing column 4 are arranged on the inner side of the end cover body 1, the bearing seat 3 is located on the periphery of the rotating shaft hole 2, and is used for installing and fixing a rotating bearing for supporting the rotating shaft, a plurality of inner fixing columns 4 are circumferentially and uniformly distributed on the periphery of the bearing seat 3, and is used for installing a generator stator assembly, an outer fixing column 5 and a boss 6 are arranged on the outer side of the end cover body 1, a plurality of outer fixing columns 5 are circumferentially and uniformly distributed on the periphery of the rotating shaft hole 2, and are used for installing an additional excitation device, the boss 6 is located on the periphery of each outer.
This embodiment is with setting up six internal fixation post 4 and four external fixation post 5 examples, and wherein, bearing frame 3, internal fixation post 4, external fixation post 5 are by end cover body 1 integrated into one piece, and overall structure nature is good, and the reliability is high, and the transportation is convenient.
When an additional excitation device needs to be installed, the protective cover is detached to expose the outer fixing column 5, and the additional excitation device is installed on the outer fixing column 5 and connected with the rotating shaft; when the extra excitation device does not need to be installed, the protective cover is installed and fixed by the boss 6, the external fixing column 5 and the rotating shaft are shielded and protected, and the device is waterproof and dustproof.
In conclusion, the end cover structure of the non-driving end of the generator is used for replacing the existing end cover, so that the end cover can fix and support the motor rotating shaft, can also be used for installing a stator assembly in the motor, is reserved with a fixing part for installing an additional excitation device, is used when needed, is expected to become a motor standard part and is pushed into the market, and has the advantages of compact structure, convenience in installation and good functionality.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
