Description
Technical field
The present invention relates to a kind of Coupler, specifically, what relate to is a kind of friction type centrifugal coupler.
Background technique
Conventional formula centrifugal coupler has 2 kinds of piece formula and steel ball types, and centrifugal all is located at inside, also can be referred to as interior centrifugal coupler.Centrifugal coupler is initiatively on the half-coupling some centrifugal of moving radially to be housed in the piece formula, and centrifugal cylindrical is inlaid with the arc friction plate, and passive half-coupling is provided with the cylinder of centrifugal of an ability suit.When the active half-coupling rotated, centrifugal force made on the centrifugal inner headed face that tightly is pressed in passive half-coupling cylinder through the arc friction plate, and that the friction torque that centrifugal force produces makes is main, passive half-coupling rotates.But limited by cylinder because of centrifugal, centrifugal force can not be adjusted, and rubbing surface can not increase, and transmitted power is little, can not satisfy the startup requirement of large power overloading equipment.Complex structure, processing difficulties.The coaxial installation sleeve of interior centrifugal coupler keeps in repair necessary mobile motor of repair demolition or working machine on the axle of motor and working machine, the same very trouble with hydraulic couplers.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency of the prior art, a kind of friction type centrifugal coupler is provided, centrifugal force can be adjusted, and can satisfy the startup requirement of large power overloading equipment, and easy to process, repair demolition is easy to operate.
For realizing above-mentioned purpose, friction type centrifugal coupler of the present invention comprises passive half-coupling, circular friction plates, face shape pressing plate, straight pin, centrifugal, initiatively half-coupling and Returnning spring.The multi-disc circular friction plates is arranged between master, the passive half-coupling.The endoporus of active friction plate is enclosed within on the active half-coupling with teeth groove; The cylindrical of driven friction is enclosed within the circle cover of passive half-coupling with teeth groove; Initiatively some centrifugal of radially wobbling also are equipped with in the outside of half-coupling; Centrifugal afterbody has a lever arm; Be provided with some straight pins between lever arm and the friction plate, Returnning spring also is housed on the centrifugal lever arm.
When the active half-coupling rotates, centrifugal outwards swing, the centrifugal force of generation promotes pin through lever arm and tightly is pressed on the circular friction plates, and the friction torque of generation rotates master, passive half-coupling.
Outer centrifugal mechanical centrifugal coupler torque transmitted is the rate variation with the quadratic curve of rotating speed of motor.Its master, passive half-coupling also are contained in respectively on motor and the working machine, and they are being flexible coupling of separating.Working principle is the same with interior centrifugal coupler, and effect too.
Further, said Coupler adopts a plurality of friction plates, and rubbing surface is an end face, and the rubbing surface number is increased to 10～20.
Further, centrifugal of said Coupler is placed on the outside, can increase easily and adjust, and quality can increase by 5～10 times.
Further, said outer centrifugal coupler, its outside centrifugal has leverage, and lever ratio can reach 1-5 doubly.
The present invention has following effect: (1) rubbing surface is many, has increased friction torque; Prolonged working life greatly.(2) maintain and replace is very convenient; (3) centrifugal is placed on the cylindrical, can increase the quality of centrifugal of adjustment easily, and centrifugal force is increased greatly; (4) through the effect of leverage, amplified the active force of centrifugal force to friction plate, increased friction torque; (5) can be designed to the structure of separated type, solve the problem of the difficult installation of the long-term puzzlement of hydraulic couplers and interior centrifugal coupler.
