Abstract
The invention provides a connecting mechanism of a low-noise fan and a motor and relates to a connecting mechanism of a fan and a motor. The invention aims at solving the problems that when the prior motor is directly connected with the fan, the fan is easy to deform, a motor shaft and the fan are in clearance fit to generate an eccentric center, and the fan vibrates to generate high noise when rotating at high speed. An extending shaft of a fan clamping sleeve passes through a center hole of a plane cover plate arranged on the upper part of the fan and deeply penetrates into a center hole of an impeller gasket, the outer wall of a motor clamping sleeve comprises a cylindrical surface and a conical surface, an output shaft of the motor is arranged in an inner cavity of the motor clamping sleeve and is fixed by a locknut, the locknut is sleeved on the motor clamping sleeve and is arranged on the upper end surface of the impeller gasket, large-diameter end surfaces of the impeller gasket and the fan clamping sleeve are respectively arranged above and under the plane cover plate, and the motor is arranged in a groove of a rectification turning and fixing seat. The connecting mechanism of a low-noise fan and a motor is used for generating vacuum negative pressure which is used for adsorbing a climbing robot on a wall.
Description
Technical field
The present invention relates to the bindiny mechanism of a kind of fan and motor.
Background technique
The fan that present wall-climbing device philtrum is used to produce negative pressure of vacuum is that motor directly is connected with the axis hole of fan with the linkage structure of motor, and the Support Position is very near from rotating center, and distortion appears in fan easily when high speed rotating, and the noise that produces vibrations is very big; Motor shaft cooperates with fan coupling shaft interporal lacuna that to hold out against easy generation with jackscrew eccentric in addition, and then produces vibrations when high speed rotating, produces noise.Because noise is bigger, climbing robot is difficult to reach application request in being applied to anti-terrorism investigation field the time.
Summary of the invention
The objective of the invention is in order to solve existing wall-climbing device philtrum motor and directly to be connected with fan, fan is prone to distortion, motor shaft and fan Spielpassung produce eccentric, and vibrations produce the problem of very big noise during high speed rotating, have proposed the bindiny mechanism of a kind of low-noise fan and motor.
The present invention solves the problems of the technologies described above the technological scheme of taking to be: described bindiny mechanism comprises fan, the impeller pad, motor chucking cover, motor, locking nut, fan chucking cover and rectification revolution fixed base, the projecting shaft of described fan chucking cover pass vertically fan top the plane cover plate center hole and be deep in the center hole of impeller pad, the outer wall of described motor chucking cover is made of cylndrical surface and conical surface from top to bottom, the diameter of the conical surface of described motor chucking cover outer wall increases from top to bottom gradually, the conical surface of described motor chucking cover outer wall and the endoporus of projecting shaft are complementary, the output shaft of described motor is contained in the inner chamber of motor chucking cover and by locking nut and fixes, described locking nut is enclosed within that motor chucking puts and by being threaded, described locking nut is arranged on the upper-end surface of impeller pad, described impeller pad and fan chucking cover major diameter end face is located at respectively on the upper and lower end face in upper-end surface of plane cover plate of fan, described motor is contained in the groove of rectification revolution fixed base, the major diameter end face of described rectification revolution fixed base is provided with annular groove, described fan is located on the rectification revolution fixed base, the major diameter end face of described rectification revolution fixed base is made as the arc shaped surface that raises up, described arc shaped surface is between the major diameter end face outward edge of annular groove and rectification revolution fixed base, and the shape of the lower end surface of arc shaped surface and fan matches.
The present invention has following beneficial effect: one, the present invention makes impeller pad 2 and fan chucking cover 6 clamp fan 1 by screwing locking nut 5, and holds the output shaft 4-1 of motor 4 tightly.Because the Area of bearing after clamping is an annular, and as far as possible away from rotating center, make when fan 1 high speed rotating supporting ﹠ stablizing, reliable, because the Support Position is far away from rotating center, reduce fan and distortion when high speed rotating, occurred, produce the situation of vibrations, effectively reduced the noise that vibrations produce.Two, the center of fan 1 of the present invention can overlap with the center of motor output shaft 4-1, has avoided traditional motor shaft to cooperate with fan coupling shaft interporal lacuna with jackscrew and has held out against generation off-centre, and then produce vibrations when high speed rotating, produces the possibility of noise.
