Abstract

The invention relates to a flexible coupler. The flexible coupler comprises an input shaft and an output shaft, wherein one end of the input shaft is connected with a conductor drum; one end surface of the conductor drum is connected with the input shaft, and the output shaft penetrates out through the other end surface of the conductor drum; conductors are circumferentially arranged on the inner side wall of the conductor drum; one end of the output shaft penetrates out of the conductor drum, and the other end is located in the conductor drum and is connected with a magnetic rotor; permanent magnets are circumferentially arranged on the outer side wall of the magnetic rotor. According to the flexible coupler disclosed by the invention, torque transmission is carried out by adopting a way of cutting magnetic induction lines by the conductors, and magnetic energy can be utilized to the maximum because a structure for cutting the magnetic lines of the permanent magnets by three conductors is adopted; under the condition of generating same torque, a device is smaller, and the precious raw materials are saved to the maximum; the flexible coupler has the functions of buffering, reducing vibration and increasing the dynamic performance of a shaft system in power transmission at an unstable rotating speed; the defects of an original flexible coupler are changed, the service life of a coupler is prolonged, the bearing capacity is increased, and critical damage to a primer motor during locked rotation of the device can be prevented.

Description

A kind of flexible clutch

Technical field

The present invention relates to a kind of torque transfer member is and in particular to a kind of flexible clutch.

Background technology

Shaft coupling is allowed to jointly rotate to transmit torsion as two axles (driving shaft and driven shaft) in connection different institutions The machine components of square are widely used.In the jiggly power transmission of rotating speed, some flexible clutch also have buffering, vibration damping and Improve the effect of shafting dynamic property.But current flexible clutch can bring mortal injury to prime mover in equipment stall.Separately Outward, existing shaft coupling is higher to the axiality requirement of driving shaft and driven shaft, increases manufacture difficulty.

Content of the invention

For the problems referred to above, the present invention provides a kind of high intensity, the flexible clutch of long service life.For solving above-mentioned asking Topic, the technical scheme that the present invention takes is: a kind of flexible clutch, and including input shaft and output shaft, input shaft one end is connected with Conductor cylinder, described conductor cylinder end face connects input shaft, and other end passes for output shaft, circumferentially disposed in conductor medial wall of the tube There is conductor；Output shaft one end passes conductor cylinder, and the other end is located in conductor cylinder and is connected with magnet rotor, described magnet rotor lateral wall week To being provided with permanent magnet.

Input shaft band moving-conductor cylinder rotates, and produces relative motion with interior permanent magnets, permanent magnetic field is being led when conductor cylinder rotates Produce on body cylinder and be vortexed, vortex produces induced field again and finally drives magnet rotor edge and conductor cylinder with permanent magnetism field interactions simultaneously Identical direction rotates, thus the output shaft rotation that is automatically connected on magnet rotor of band export power.Present invention can be suitably applied to turn In the jiggly power transmission of speed, bearing capacity is strong, long service life, can prevent the mortal wound to prime mover during equipment stall Evil.

For ease of conductor cutting magnetic induction line, described conductor cylinder is in hollow cylinder, and conductor circumferential array is in conductor cylinder Inner peripheral surface.

Described magnet rotor is in the form of annular discs, and permanent magnet circumferential array is in the outer circumference surface of magnet rotor.

In described conductor cylinder, the end face that output shaft passes is provided with removable end cap.In the setting of end cap both can have been protected Portion's structure is not subject to damage, is easy to when breaking down carry out on-call maintenance again or changes part.Conductor cylinder and end cap are common Composition closing space, reduces leakage field, reduces outer magnetic to internal interference simultaneously, also reduces internal impact to external world, isolation shake Dynamic, extend service life.

For ease of more fully cutting magnetic induction line, inside the end face of conductor cylinder connection input shaft and right inside end cap The position answering permanent magnet is equipped with conductor.

Preferably, two magnetic poles of described permanent magnet are circumferentially distributed along magnet rotor.

Preferably, two magnetic poles of described permanent magnet are along magnet rotor radial distribution.

Described permanent magnet is unipolarity permanent magnet.

The present invention carries out moment of torsion transmission by the way of conductor cutting magnetic induction line, due to employing three face conductor cutting permanent magnetism The structure of the body magnetic line of force, can utilize magnetic energy to greatest extent, produce equal moment of torsion under conditions of, make equipment more smart little simultaneously Save rare, valuable raw material to greatest extent.In the jiggly power transmission of rotating speed, there is buffering, vibration damping and improve axle It is the effect of dynamic property；In many power links driving means (as belt conveyor), can be transmitted with balanced power, prevent individual Other motive power outputting apparatus transship damage because of step-out.Change conventional flexible clutch using being that rubber, nylon etc. bring Drawback, extends the service life of shaft coupling, improves bearing capacity, and can prevent the mortal wound to prime mover during equipment stall Evil.
