Abstract
The utility model discloses a triangular plate fixing structure for fan blades of a motor. The triangular plate fixing structure for the fan blades of the motor comprises the motor, a motor fixation rack, a fan and a triangular plate, wherein the fan comprises the fan blades and a fan support, the fan blades are circumferentially and uniformly distributed on the fan support, a central shaft hole in linkage connection with a motor output shaft is formed in the fan support, the motor is arranged inside the motor fixation rack, the motor output shaft penetrates the motor fixation rack to be in linkage connection with the fan, the triangular plate is arranged between the motor fixation rack and the fan and sleeved with and fixed on the motor output shaft, three or more than three screw holes fixed with the fan support are formed in the triangular plate and circumferentially and uniformly distributed, according to the principle that three points not positioned in the same straight line can define a plane surface, the original one-point positioning and fixing between the fan and the motor output shaft is changed to be surface positioning and fixing, the smoothness of the fan blades of the fan doing circumferential rotation around the motor output shaft can be enhanced greatly, and the linkage connection between the fan and the motor becomes firmer.
Description
Technical field
The utility model relates to a kind of motor flabellum, especially a kind of motor flabellum triangle dish fixed structure.
Background technology
The motor of tradition band fan, two kinds of fixed forms are arranged: 1, fan directly is enclosed within on the motor output shaft, fan and motor output shaft are fixed and clamped with elastic card, but elastic card elastic force does not often reach requirement, make fan fixing not firm, elastic card is cannot kept under control fan, the swing of motor when rotation fan, rocks greatlyyer, and balance of fan is relatively poor; 2, fan directly is enclosed within on the motor output shaft, fan and motor output shaft are fixed and clamped with screw thread, but the inserts that this structure occurs in the blower tray easily comes off because of plastic molting, and above two kinds of fixed forms are a pressure mode, such fixed form is extremely insecure, because fan and motor output shaft are to fix by the mode of a point location, so the flabellum that fan is provided with is when circumference rotates, can't accomplish steadily, in case be subjected to the effect of external force, fan will take place, situation such as have a down dip, fan is damaged or and motor output shaft between come off, make troubles to the user.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of motor flabellum triangle dish fixed structure that fan can be stably fixed on the motor output shaft.
For achieving the above object, the utility model provides a kind of motor flabellum triangle dish fixed structure, comprise motor, motor fixing frame, fan, the triangle dish, wherein fan comprises flabellum and blower tray, the flabellum circumference uniform distribution is on blower tray, blower tray is provided with the central shaft hole that is connected with motor output shaft, motor is arranged in the motor fixing frame, motor output shaft passes motor fixing frame and fan is connected, be provided with the triangle dish between motor fixing frame and the fan, motor and motor fixing frame are connected and fixed by screw, and the socket of described triangle dish also is fixed on the motor output shaft, and the triangle dish is provided with and several fixing screws of blower tray.
The utility model can further be set to described triangle dish be provided with the fixing screw of blower tray be more than three or three, and circumference uniform distribution.
The beneficial effects of the utility model are: owing to be provided with the triangle dish between motor output shaft and fan, the socket of described triangle dish also is fixed on the motor output shaft, the triangle dish is provided with and three fixing or three above screws of blower tray simultaneously, and described screw is circumference uniform distribution, based on three not the point on same straight line can determine the principle on a plane, so be improved to the face positioning and fixing by original some positioning and fixing between fan and the motor output shaft, strengthened the smoothness the when flabellum on the fan is done the circumference rotation around motor output shaft greatly, made the interlock of fan and motor become more firm.
Description of drawings
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is an explosive view of the present utility model.
Embodiment
As Fig. 1, provided a kind of motor flabellum triangle dish fixed structure shown in 2, comprise motor 1, motor fixing frame 2, fan 3, triangle dish 4, wherein fan 3 comprises flabellum 31 and blower tray 32, flabellum 31 circumference uniform distributions are on blower tray 32, blower tray 32 is provided with the central shaft hole 321 that is connected with motor output shaft 11, motor 1 is arranged in the motor fixing frame 2, motor output shaft 11 passes motor fixing frame 2 and is connected with fan 3, be provided with triangle dish 4 between motor fixing frame 2 and the fan 3, motor 1 and motor fixing frame 2 are connected and fixed by screw, described triangle dish 4 sockets also are fixed on the motor output shaft 11, triangle dish 4 is provided with the screw of fixing with blower tray 32 41, described screw 41 is three, and be the equal portion of circumference, screw 5 passes screw 41 that screw 322 that blower tray 32 is provided with and triangle dish 4 be provided with fan 3 firm being fixed on the triangle dish 4.
Owing to be improved to the face positioning and fixing by original some positioning and fixing between fan 3 and the motor output shaft 11, smoothness when having strengthened flabellum 31 on the fan 3 greatly and doing the circumference rotation around motor output shaft 11 makes the fan 3 and the interlock of motor 1 become more firm.
Claims (2)
1. motor flabellum triangle dish fixed structure, it is characterized in that: comprise motor, motor fixing frame, fan, the triangle dish, wherein fan comprises flabellum and blower tray, the flabellum circumference uniform distribution is on blower tray, blower tray is provided with the central shaft hole that is connected with motor output shaft, motor is arranged in the motor fixing frame, motor output shaft passes motor fixing frame and fan is connected, be provided with the triangle dish between motor fixing frame and the fan, motor and motor fixing frame are connected and fixed by screw, the socket of described triangle dish also is fixed on the motor output shaft, and the triangle dish is provided with and several fixing screws of blower tray.
