Abstract
A motor of a novel structure comprises a motor shaft and a wind wheel. One end of the motor shaft is provided with a dovetail groove. A tail end of the dovetail groove is provided with a clamping groove. The wind wheel comprises a wheel disc and at least two blades. A shaft disc is arranged on the central portion of the wheel disc. The shaft disc is cylindrical. A projection matched with the dovetail groove is arranged in the shaft disc. A buckle matched with the clamping groove is arranged at a tail end of the projection. The blades are distributed uniformly on the external surface of the wheel disc in an axial direction. The bottom surfaces of the blades extend in a radial direction to side walls of the wheel disc. According to the motor of the novel structure, through the matching of the dovetail groove with the projection, the motor is firmly fixed on the motor shaft in an axial direction and a radial direction; the matching of the clamping groove arranged at the end of the dovetail with the buckle on the wind wheel further restricts the freedom degree of the wind wheel in the radial direction, and the wind wheel is firmly fixed on the motor shaft; the connection is fastened; the structure is stable; the integral strength of the motor is raised; and the usage life is prolonged.
Description
Technical field
The utility model relates to machine field, relates in particular to a kind of motor of new structure.
Background technology
Fan blade is a very important part in motor, fan blade when mounted, need to firmly be fixed on motor shaft, fixing general flat key or the pin of adopting of traditional fan blade and motor shaft fixed, and can make like this face length time stress of flat key and pin concentrate, and causes wearing and tearing or takes exercise, thereby producing noise even makes fan blade lose efficacy, and traditional fan blade can only realize axial restraint, axially in the time of operation, can there is certain skew, cause the damage of fan blade.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and connects the motor of fastening and constitutionally stable new structure.
For solving the problems of the technologies described above, the utility model provides a kind of motor of new structure, comprise motor shaft and fan blade, one end of described motor shaft offers dovetail groove, the tail end of described dovetail groove is provided with draw-in groove, described fan blade comprises wheel disc and at least two blades, the middle part of described wheel disc is provided with reel, described reel is cylinder, on described reel, offer the projection suitable with dovetail groove, the tail end of projection is provided with the buckle coordinating with draw-in groove, and described bit pressing shaft is to all walking at wheel disc outer surface, and the bottom surface of described blade radially extends on the sidewall of wheel disc.
The utility model improves to be had, and the material of described fan blade is plastics.
The utility model improves to be had, and described wheel disc and blade are one-body molded.
The utility model improves to be had, and the inner surface of described wheel disc is provided with reinforcement.
The beneficial effects of the utility model are: the motor of new structure, by dovetail groove and protruding coordinating, make motor shaft to and be radially firmly fixed on motor shaft, on the draw-in groove of dovetail groove end setting and fan blade, the cooperation of buckle has further limited the radially degree of freedom of fan blade, fan blade is firmly fixed on motor shaft, connect fastening, Stability Analysis of Structures, promoted the bulk strength of whole motor, extended useful life.
Accompanying drawing explanation
The structural representation of the motor that accompanying drawing 1 is new structure of the present utility model;
The structural representation that accompanying drawing 2 is blade of the present utility model.
Label declaration: 1-motor shaft; 11-dovetail groove; 12-draw-in groove; 13-buckle; 2-fan blade; 21-wheel disc; 22-blade; 23-reel; 24-projection.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
With reference to accompanying drawing 1 and accompanying drawing 2, the utility model shown in accompanying drawing provides a kind of motor of new structure, comprise motor shaft 1 and fan blade 2, one end of described motor shaft 1 offers dovetail groove 11, the tail end of described dovetail groove 11 is provided with draw-in groove 12, described fan blade 2 comprises wheel disc 21 and at least two blades 22, the middle part of described wheel disc 21 is provided with reel 23, described reel 23 is cylinder, on described reel 23, offer the projection 24 suitable with dovetail groove 11, the tail end of projection 24 is provided with the buckle 13 coordinating with draw-in groove 12, described blade 22 is circumferentially evenly arranged on wheel disc 21 outer surfaces.
In the time that fan blade 2 is installed, first the projection on reel 23 24 is aimed to dovetail groove 11, at this moment the buckle 13 of tail end can be extruded, projection 24 stretches in dovetail groove 11, realized motor shaft 1 to and radially fixing, when fan blade 2 moves to after assigned address, the buckle 13 of reel 23 tail ends can snap in draw-in groove 12, the axial freedom of fan blade 2 is limited, and fan blade 2 is just firmly fixed on motor shaft 1.
In the present embodiment, the material of described fan blade 2 is plastics, has reduced the weight of fan blade 2 in guaranteeing whole fan blade 2 intensity.
Simultaneously, by projection 24 and the coordinating of dovetail groove 11, stress is transmitted by whole fan blade 2, further extend the life-span of whole motor, drive more stablely, in addition, can offer multiple dovetail grooves 11 in all sides of motor shaft 1 as required, fan blade 2 correspondences arrange multiple protruding 24, further strengthen coordinating of fan blade 2 and motor shaft 1.
In the present embodiment, described wheel disc 21 is one-body molded with blade 22.
The ground of blade 22 radially extends on the sidewall of wheel disc 21, and this structure has improved the intensity of blade 22, not frangibility, on the inner surface of wheel disc 21, be provided with reinforcement, reinforcement is circumferentially uniform, has further improved the intensity of whole motor, has extended useful life.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
