Centrifugal clutch coupling is the clutch coupling that a kind of centrifugal force relying on centrifugal body to produce reaches separation automatically or combines; centrifugal clutch arrangement is simple, compact dimensions; its combination or separation just can be controlled by controlling the rotating speed of transmission shaft; without the need to special operating mechanism; after overload, centrifugal clutch coupling also can skid automatically; there is safeguard protection effect, therefore it is a kind of clutch coupling widely used on engineering goods.
At present, existing centrifugal clutch coupling is generally made up of three parts: driving link, centrifugal part and driven member, driving link and centrifugal part are slidably connected, centrifugal part outside surface contacts cooperation with driven member internal surface, when driving link reaches certain speed, the centrifugal force that centrifugal part produces makes centrifugal part and driven member fit tightly and then drive driven member to enter kinestate and transmits moment of torsion, although this kind of centrifugal clutch coupling structure is simple, but will there is sliding friction in centrifugal part and driven member internal surface in starting process, thus the smooth engagement making clutch coupling is poor, centrifugal part is easy to wear.
Practical novel content
The utility model is intended to provide a kind of centrifugal clutch coupling of many springs, to solve clutch coupling in conjunction with stationarity difference, the problem that centrifugal part is easy to wear.
The centrifugal clutch coupling of many springs in this scheme, comprise motion-work wheel and the follow-up pulley that arrange concentric on motion-work wheel that transmission shaft is connected with transmission shaft, motion-work wheel is interior, follow-up pulley is outside, motion-work wheel is evenly equipped with four projections, it is equipped with brake shoe between adjacent two projections, brake shoe totally four, brake shoe can along protruding radial motion, two extension springs it are equipped with between each brake shoe and motion-work wheel, extension spring one end is connected with brake shoe, and the extension spring the other end is connected with motion-work wheel, will produce and prolonging direction opposite effect power when extension spring is stretched.
The principle of work of this scheme is: when transmission shaft is static or rotating speed is lower, under the reactive force of extension spring, brake shoe and follow-up pulley are separate stage, when transmission shaft motion reaches certain speed, the centrifugal force of brake shoe exceedes the reactive force of extension spring and then makes brake shoe along protruding radial to follow-up pulley lateral movement, until brake shoe end face and follow-up pulley inwall are tightly fitted, move together with making follow-up pulley under the frictional force effect of follow-up pulley at brake shoe, and then carry out the transmission of torque.
The useful effect of this scheme is: by arranging extension spring between brake shoe and motion-work wheel, make that transmission shaft is static or low cruise constantly, follow-up pulley and brake shoe are in separate stage, therefore in starting process, sliding friction is there will be no between brake shoe and follow-up pulley, thus the cohesive process making clutch coupling is more steady, brake shoe is not easy to wear.
Further, frictional force in order to increase between brake shoe and follow-up pulley, it is to increase the reliability of transmission of torque, every shoe brake block is equipped with friction plate towards follow-up pulley side.
Further, in order to make the contact area of friction plate and follow-up pulley maximum, the frictional force of generation is maximum, and friction plate cylindrical circular arc radius-of-curvature equals follow-up pulley inner circle circular arc radius-of-curvature.
