The invention discloses a centrifugal clutch with a ventilation system. The centrifugal clutch comprises a driving shaft, a rotor, centrifugal blocks and a driven shell, wherein the driving shaft is connected with the rotor; the rotor and the driven shell are arranged in a concentric manner; four first bulges are uniformly distributed on the rotor in the circumferential direction; a second bulge is arranged at each first bulge; each centrifugal block movably sleeves the corresponding second bulge; a friction piece is arranged at each centrifugal block; a plurality of heat emission holes are formed in the matching surface of each centrifugal block and the corresponding friction piece; and tension springs are arranged between the rotor and the centrifugal blocks. According to the scheme, the heat emission holes are additionally formed in the centrifugal blocks, and the contact areas of the centrifugal blocks and the air are enlarged through the heat emission holes, so that the heat radiating areas of the centrifugal blocks are enlarged, the heat transferred from the friction pieces to the centrifugal blocks is effectively emitted in time through the heat emission holes, the heat stability of the friction pieces during the working process is guaranteed, and the working performance of the clutch is enabled to be stable and reliable.
Description
Technical field
The present invention relates to centrifugal clutch, be specially a kind of centrifugal clutch with ventilation system.
Background technique
Centrifugal clutch is that a kind of centrifugal force relying on centrifugal body to produce reaches the clutch being automatically separated or combining; centrifugal clutch arrangement is simple, compact dimensions; just can control it by the rotating speed controlling transmission shaft to combine or be separated; without the need to special operating mechanism; after overload, centrifugal clutch also can skid automatically; having safety protection effect, is therefore widely used a kind of clutch on engineering goods.
At present, existing centrifugal clutch is generally made up of three parts: driving link, centrifugal and driven member, when driving link reaches certain speed, centrifugal the centrifugal force produced, centrifugal fits tightly with driven member under the influence of centrifugal force, move with centrifugal at driven member driven member under the frictional force effect of centrifugal, the clutch of this structure in use, frictional force will produce a large amount of heats between centrifugal and driven member, if and this heat can not distribute timely and makes the service behaviour of clutch decline, have influence on the reliability of clutch work.
Summary of the invention
The invention is intended to provide a kind of centrifugal clutch with ventilation system, to solve the problem that clutch heat distributes the service behaviour decline caused not in time.
The centrifugal clutch with ventilation system in this programme, comprise driving shaft, rotor, centrifugal-block and driven shell, driving shaft is connected with rotor, rotor is arranged with driven shell is concentric, on rotor, circumference is evenly equipped with four first projections, each first high spot is provided with the second projection that width is less than the first projection, centrifugal-block kink is in the second projection, centrifugal-block place is provided with friction plate, centrifugal-block and friction plate fitting surface offer some radiation holes, also be provided with extension spring between rotor and centrifugal-block, extension spring one end and centrifugal-block offset, and the extension spring the other end and rotor offset.
The principle of this programme is: rotor moves under the drive of driving shaft, when rotor speed does not reach the synchronous speed of clutch combination, centrifugal-block is separated with driven shell under extension spring effect, when rotor speed reaches the synchronous speed of clutch combination, centrifugal-block band movable friction plate overcomes the active force of extension spring and moves to direction, driven shell place, until friction plate and driven shell are fitted, now frictional force will be produced between friction plate and driven shell, driven shell will move with friction plate under the effect of frictional force, thus realize the transmission of torque of clutch, in the process of transmission of torque, frictional force will make to produce a large amount of heats between friction plate and driven shell, heat on friction plate will be delivered on the centrifugal-block that directly contacts with friction plate, the heat be delivered on centrifugal-block is directly contacted with air by radiation hole, thus heat can be distributed timely and effectively.
This programme by setting up radiation hole on centrifugal-block, the area of contact of centrifugal-block and air is increased by radiation hole, thus increase the heat diffusion area of centrifugal-block, the heat that friction plate is delivered on centrifugal-block distributes timely and effectively by radiation hole, ensure that friction plate thermostability in the course of the work, make the stable and reliable working performance of clutch.
Further, driven shell is provided with some radiating fin, and radiating fin has tapering, and the radiating fin on driven shell can increase the heat diffusion area of driven shell further, and radiating fin has tapering and improves the production of driven shell and the convenience of processing.
Further, position vertical with radiation hole on centrifugal-block also offers vent hole, and vent hole communicates with radiation hole, and the asperities that connects that vent hole can increase centrifugal-block and air further amasss, and improves the heat dissipation potential of centrifugal-block.
Further, in order to when not affect the installation and removal making friction plate and centrifugal-block friction plate normally works convenient, friction plate is connected by rivet with centrifugal-block, and the rivet mounting hole place of friction plate offers the groove for placing rivet head.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
