Centrifugal clutch coupling is the clutch coupling of a kind of common form, centrifugal clutch coupling is generally made up of three parts: driving link, centrifugal part and driven member, the driving and driven part of centrifugal clutch coupling is before reaching synchronous axial system, the cohesive process of centrifugal body and driven member is actual is sliding friction process, in the process by the abrasion with friction heating and friction pair, and consume the energy of a part, therefore centrifugal clutch coupling should not be used for the operating mode of Fraquent start.
Practical novel content
The utility model is intended to provide a kind of operating mode being applicable to Fraquent start, and the simple centrifugal clutch coupling open in usual of structure.
Open in usual centrifugal clutch coupling in this scheme, comprise main drive shaft, rotor and shell, main drive shaft cylindrical is connected with rotor engagement, rotor is arranged with shell is concentric, and periphery of rotor is evenly equipped with four projections, is formed with groove between adjacent two projections, centrifugal iron block all it is arranged with in groove, centrifugal iron block along protruding radial motion, can be equipped with permanent magnet between centrifugal iron block and rotor, and permanent magnet is arranged on the outside surface of rotor.
The principle of work of this scheme is: arrange permanent magnet at rotor outer surface, centrifugal iron block is produced magnetism by permanent magnet, when main drive shaft is static or speed is lower, under the magnetism of permanent magnet, centrifugal iron block is separated with shell, now do not transmit moment of torsion, for the separate stage of clutch coupling, when main drive shaft rotating speed reaches certain value, centrifugal iron block produces bigger centrifugal force, the direction of centrifugal force is contrary with the direction of magnetism, when centrifugal force is greater than magnetism, centrifugal iron block will move to direction, centrifugal force place, namely centrifugal iron block moves along protruding to shell direction, when centrifugal iron block and shell are fitted, drive shell is moved by centrifugal iron block together, thus reach the object of driving torque, namely the joint of clutch coupling is realized.
The useful effect of this scheme is: utilize permanent magnet that object is produced the characteristic of magnetism, at rotor outer surface, permanent magnet is set, when main drive shaft does not meet the requirements of synchronous speed, centrifugal iron block is attracted to make centrifugal iron block and shell realize being separated by permanent magnet, when main drive shaft reaches synchronous speed, centrifugal iron block overcomes permanent magnet magnetism and engages with shell, thus avoid friction and the heating of the generation between centrifugal iron block and shell before reaching synchronous speed of traditional centrifugal clutch coupling, therefore clutch coupling in this scheme is applicable in the operating mode of Fraquent start, and clutch configuration is simple.
Further, in order to make the stable connection between permanent magnet and rotor reliable, permanent magnet and rotor are linked together by tightening screw.
Further, frictional force in order to increase between centrifugal iron block and shell, it is to increase the reliability of transmission of torque, the centrifugal iron block of every block is equipped with friction plate towards shell side.
Further, offered the 2nd groove on protruding, projection has been offered the kind that the 2nd groove can alleviate whole wheelwork, thus reduces the energy waste of wheelwork.
