Description

Reversible electromagnetic clutch

Technical field

This utility model relates to clutch field, is specially a kind of reversible electromagnetic clutch.

Background technology

Clutch is the device realizing actively having joint or separation function on coaxial line when transmitting movement and power with secondary part, it it is mechanical part conventional in machine drive mechanism, clutch generally adopts the operating mechanisms such as lever directly to handle joint element, makes clutch engage or separates.

Conventional clutch relies on the combination of two halves clutch disc and separates the transmission and the interruption that realize power, the kind of clutch is a lot, mainly include mechanical clutch, pneumatically controlled clutch, hydraulic clutch, electromagnetic clutch etc., but no matter which kind of clutch, when driving shaft rotation direction is constant, the rotation direction of driven shaft also cannot change, if desired for change driven shaft rotation direction time, then must change the rotation direction of driving shaft, therefore driven shaft is needed not stop to change in nyctitropic use occasion at some, then must obtain and not stop to change driving shaft rotation direction, this will make whole operating process very loaded down with trivial details, and work efficiency will be substantially reduced.

Utility model content

This utility model is intended to provide a kind of when driving shaft rotation direction is constant, can realize the reversible electromagnetic clutch of the operating of driven shaft different directions and simple in construction.

Reversible electromagnetic clutch in this programme, including driving shaft, driven shaft, first electric magnet and the second electric magnet, driving shaft is provided with master bevel gear, master bevel gear both sides are engaged with the first bevel gear and the second bevel gear respectively, first bevel gear is sheathed on the first electric magnet, second bevel gear is sheathed on the second electric magnet, first electric magnet and the equal kink of the second electric magnet are on driven shaft, driven shaft is also sequentially provided with the first pressure ring between the first electric magnet and the second electric magnet, main pressure ring and the second pressure ring, first pressure ring and the second pressure ring kink are on driven shaft, main pressure ring and driven shaft interference fit, first pressure ring is positioned at the first electric magnet side, second pressure ring is positioned at the second electric magnet side, at least one first extension spring it is provided with between first pressure ring and main pressure ring, at least one second extension spring it is provided with between second pressure ring and main pressure ring, first extension spring one end and the first pressure ring offset, the first stage clip other end and main pressure ring offset, second extension spring one end and the second pressure ring offset, the second extension spring other end and main pressure ring offset.

Principle and the benefit of this programme be: driving shaft rotates and drives master bevel gear to rotate, the first bevel gear and the second bevel gear that are now placed in bevel gear both sides move to different directions respectively, when to the first electric magnet energising, first electric magnet makes the first pressure ring overcome the active force of the first extension spring to move to the first electric magnet direction, until the first electric magnet and the laminating of the first pressure ring, now under the drive of the first electric magnet, first pressure ring drives the motion of main pressure ring by the first extension spring, main pressure ring and then drive driven shaft motion, realize torque transmission, when needs driven shaft adverse movement, stop being energized to the first electric magnet, first pressure ring separates with the first electric magnet under the effect of the first extension spring, now it is energized to the second electric magnet, second electric magnet makes the second pressure ring overcome the active force of the second extension spring to move to the second electric magnet direction, until the second electric magnet and the laminating of the second pressure ring, now under the drive of the second electric magnet, second pressure ring drives the motion of main pressure ring by the second extension spring, main pressure ring and then drive driven shaft move round about. it is achieved thereby that when driving shaft rotation direction is constant, driven shaft can operate to different directions according to loading condition, and the simple in construction of this programme, easy to operate simultaneously.

Further, in order to make the stress between the first pressure ring, the second pressure ring and main pressure ring uniform respectively, the first extension spring and the second extension spring are two.

Further, in order to make the impact of electric magnet, noise little, reliability is high, and the first electric magnet and the second electric magnet are DC electromagnet.

Further, in order to make the first electric magnet and the second electric magnet after a loss of power can demagnetization at once, the first electric magnet and the second electromagnet core all adopt demagnetization soft iron faster or magnet steel.
