Abstract
A winding type permanent magnet clutch comprises a permanent magnet rotor and a winding rotor which are arranged coaxially, and the permanent magnet rotor and the winding rotor are respectively fixed on a first rotating shaft and a second rotating shaft. The permanent magnet rotor is composed of a permanent magnet and a housing fixing magnetic steel, and an N pole and an S pole of the permanent magnet are alternatively and uniformly distributed on the housing. The winding rotor is composed of a coil winding and an iron core, and the coil winding is embedded in a groove of the iron core. An air gap is arranged between the permanent magnet rotor and the winding rotor, collector rings and carbon brushes are arranged on the second rotating shaft, the coil winding forms a loop with an external connection direct current power supply through the collector rings and carbon brushes by using leading connecting wires, and the connection and disconnection of the loop is controlled by an electric switch. When a direct current power supply is disconnected, no excitation magnetic field exists in the coil winding since no direct current exists in the coil winding, so that no magnetic torque will be generated and accordingly the clutch is in a separating state.
Description
Technical field
The present invention is a kind of new construction without friction clutch, belongs to clutch category, and in its course of work, clutch does not have mechanical action, is carried out the Engage and disengage of solenoidoperated cluthes by the break-make of electric switch.
Background technology
Clutch is a kind of device that can realize having when driving and driven part transmits motion and power on coaxial line by various maneuverability pattern joint or separation function.Conventional clutch presses the operation principle of joint element transmission, positive clutch and slip clutch can be divided into, by realize from, close the process of action and can be divided into control type and autocontrol, mechanical type, vapour-pressure type, fluid pressure type and electromagnetic type etc. can be divided into again by the maneuverability pattern of clutch, conventional clutch all above, invariably there are friction, wearing and tearing, or for realize from, close function and increase the shortcoming such as various loaded down with trivial details actuators.A kind of electromagnetic slip clutches solve variety of problems above well, the Engage and disengage of its clutch is the same with the present invention, also be controlled by the break-make of electric switch, but the maximum problem of electromagnetic slip clutches is: there is rotating speed loss, that is its output speed is always less than and proceeds to rotating speed, and this is just inapplicable in the occasion very high to rotation speed requirements.Mechanism of the present invention solves above variety of problems well, has filled up the blank of this type of clutch.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of installation, debug simply, compact conformation, manipulates freely, without rubbing, wearing and tearing, safe and reliable clutch.
Concrete structure of the present invention is: a kind of winding type Permanent Magnet Clutch, includes p-m rotor and the wound rotor of coaxial setting, is separately fixed in rotating shaft one and rotating shaft two.P-m rotor is made up of the housing of permanent magnet and fixing magnet steel, and permanent magnet N pole and S pole is alternately evenly arrangement on housing.Wound rotor is made up of coil windings and iron core, and coil windings is embedded in the groove of iron core.Be provided with air gap between p-m rotor and wound rotor, rotating shaft two be provided with collector ring and carbon brush, coil windings lead wire to be connected with external direct current power supply by collector ring and carbon brush and forms loop, controls break-make by electric switch.
Clutch operation principle of the present invention is: after coil windings passes to direct current, and the magnetic field interaction that its excitation field and permanent magnet produce produces moment, because p-m rotor is equal with wound rotor number of poles, and thus can synchronously transmitting torque and rotating speed.
When disconnecting DC power supply, there is no excitation field without direct current in coil windings, thus can not produce electromagnetic torque, being equivalent to clutch and being in released state.
