With the immediate prior art of the present invention be Japanese patent application, name is called " magnetic spiral pieces ", publication number is flat 1-209222, open day is on August 23rd, 1998.The disclosed magnetic spiral pieces of this patent application, its structure comprise that the axle under bearings that two ends are fixed on the framework is a roller, and banded magnet is equipped with in the outside of axle, is fixed on the axle with spiral-shaped; One end of axle is fixed with belt pulley, rotates by the motor drives axle; Can do rectilinear motion slip carrier (cover) along the directive slide track on the framework, the inner surface fixed placement of slip carrier has spiral helicine magnet.When motor starting, axle rotates, and the banded magnet in the axle outside and the magneticaction of the magnet in the cover are accompanied by the rotation of axle, and cover is done rectilinear motion along directive slide track.If the motor de-rotation, then cover is toward swivel motion.Because the prior art weak point is: the first, because magnetic patch is a helical arrangement, allow the reciprocating motion of slide block carrier, must make the motor commutation, allow a backward rotation, very inconvenient, fragile parts; The second, because magnetic patch row has expired the surface of whole axle, when like pole is relative, may cause the slip carrier movement not smooth, thereby increase the frictional force of rotation axis or translation shaft.
The present invention designs new magnetic circuit for overcoming the deficiencies in the prior art, reaches the rotation direction that does not change axle and just makes the automatic reciprocating rectilinear motion of slip carrier, makes magnet be coupled free and reduce the purpose that translation shaft rubs.
The present invention is by oval-shaped magnetic orbit ring, and this orbit ring tiltedly is embedded on the roller.This roller is made with high strength non-magnetic material, and roller is equipped with internal tooth belt pulley or gear wheel, gear all can.Have in addition motor pass through in the transmission of cingulum or chain, gear can drive roller and axially freely rotating.
Axially parallel and can be suitably by debugging be equipped with on the close position of roller the directive slide track of good rigidity at roller.The slip carrier is housed on directive slide track, this slip carrier can only straight reciprocating motion on the directive slide track direction, setting-in rare-earth permanent magnet firm on the slip carrier claims the carrier magnet, makes oval magnetic orbit ring on magnetic pole and the roller state that is that there is a natural attraction between the sexes.According to actual needs, the distance on debugging carrier magnet and the roller between the magnetic orbit ring can change magnetic pole coupling dynamics, so, adjusts to optimum state, can save power of electric motor, improves the power of the straight reciprocating motion of slip carrier.Said apparatus makes the roller rotation by transmission mechanism when motor rotates, slip carrier on the directive slide track is by the effect of magnet coupling, the slip carrier can be done straight reciprocating motion, the reciprocating frequence of slip carrier is determined that by the rotating speed of roller the distance that its one way is slided is determined by the length of oval magnetic orbit on the roller.Magnetic orbit ring on the roller can be one, two, or even more than two.Carrier magnet on the corresponding slip carrier also is monolithic, two, even to more than two.Be that the two number and installation site are corresponding.
The present invention is widely used in linear reciprocating motion in the electromechanical equipment such as planer, press machine, all kinds of Knitting Machinery, woodworking machinery and many household electrical appliance and all kinds of medical treatment, health care facility.Can replace eccentric wheel, lever etc. in electromechanical industries makes circular motion become the conventional art equipment of straight reciprocating motion.
Concrete structure of the present invention is provided by following examples and accompanying drawing.
