Abstract
A kind of generator with external fan structure, including main body, rotor, stator, rectification module are provided with the main body, the rotating shaft of rotor is connected with belt pulley, rotating shaft between the belt pulley and main body is provided with external fan, and the external fan has demountable structure.In the utility model that fan is external, axis of rotation drives fan to rotate, therefore fan structure can not be limited by generator space, can do greatly, therefore intake is big, good cooling results, while the fan of demountable structure is convenient for changing.
Description
Technical field
The utility model belongs to alternator for vehicle field, and in particular to a kind of generator with external fan structure.
Background technology
Alternator for vehicle is equipment essential in automobile, and the alternator for vehicle model of different automobile types is of different sizes, but
Internal structure is essentially the same, while in order to make full use of space, the general small volume of alternator for vehicle.Generator at work,
Rotor high-speed rotation is generated electricity, and quantity of heat production is big, it is necessary to be cooled using fan during being somebody's turn to do.
Existing many alternator for vehicle are typically cooled using built-in fans, but are often limited to generator space
It is narrow and small, fan can not be done greatly, cause cooling-down effect poor, cause temperature is too high to cause generator to be damaged.
Therefore, applicant is studied in problem above.
Utility model content
Deficiency of the prior art, the utility model provide a kind of generating with external fan structure for more than
Machine, it can be dried externally to generator, good cooling effect, and convenient disassembly.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals.
A kind of generator with external fan structure, including main body, rotor, stator, rectification mould are provided with the main body
Block, the rotating shaft of rotor are connected with belt pulley, and the rotating shaft between the belt pulley and main body is provided with external fan, the external wind
Fan has demountable structure.
In the utility model that fan is external, axis of rotation drives fan to rotate, therefore fan structure can not be generated electricity
Machine inner space is limited, and can do greatly, therefore intake is big, good cooling results, while the fan of demountable structure is convenient for changing.
Preferably, the external fan includes outer cover and blade assembly, the outer cover is provided with stomata, and outer cover is divided into
Two cover members, casing outer wall are provided with the first lock ring circle of annular.First lock ring circle is common endless metal hoop or bullet
Property rubber ring, after removing the first lock ring circle, outer cover is divided into two, conveniently remove replacing or cleaning.
Preferably, the external fan includes outer cover and blade assembly, the blade assembly includes being arranged in rotating shaft
Mounting ring, the blade in mounting ring, the mounting ring is divided into two installation ring assemblies, and the outer wall of mounting ring is provided with
Second lock ring circle.Second lock ring circle is common endless metal hoop or elastic rubber ring, after removing the second lock ring circle, mounting ring one
It is divided into two, conveniently removes replacing or cleaning.
Preferably, the main body is provided with mounting structure.
Compared with prior art, the utility model has the advantages that：Providing one kind has external fan structure
Generator, simple in construction, good cooling results, and external fan has dismountable structure, is convenient for changing and repairs.

Between rotating shaft be provided with external fan 3, the external fan 3 has demountable structure.
Specifically, the external fan 3 includes outer cover and blade assembly, the outer cover is provided with stomata 32, and outer cover point
For two cover members, casing outer wall is provided with the first lock ring circle 31 of annular, the lines A in Fig. 3 for two cover members it
Between distinguishing limit, outer cover by magnetic part or buckle structure attachment on the body 1, not with axis of rotation；The blade group
Part includes the mounting ring 36 in rotating shaft, the blade 35 in mounting ring 36, and the mounting ring 36 is divided to for two installations
Ring assemblies, and the outer wall of mounting ring 36 is provided with the second lock ring circle 37, lines B is two areas installed between ring assemblies in Fig. 4
Boundary.First lock ring circle 31 and the second lock ring circle 37 can be endless metal hoop or elastic rubber ring, when removing the first lock ring
The lock ring circle 37 of circle 31 and second, outer cover and mounting ring 36 are divided into two, easy to disassemble.
In addition, the main body 1 is provided with mounting structure 11, it is easily installed on location.
Described above, the utility model provides a kind of generator with external fan structure, simple in construction, cooling effect
Fruit is good, and external fan has dismountable structure, is convenient for changing and repairs.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
