Abstract
The linear motor includes metal case, two groups of coils in opposite direction enwound on 4 plastic coil racks and iron core sheets. Each coil rack is between iron core sheets. Coil racks and iron core sheets are installed inside metal case. Concentric holes in same diameter are setup on coil racks and iron core sheets. Hollow aluminum tube longer than length of the metal case passing through concentric holes is as guide rail of motor. Hollow aluminum tube is sheathed on a piece of solid iron rod. Coil racks and iron core sheets as well as metal case can be slidden on the aluminum tube. Comparing with traditional linear motor, the invention cancels copper ring so as to increase effective area of iron core sheets, simplifies structure. Features are simple structure, high efficiency and long service life.
Description
Technical field:
The present invention relates to a kind of reversible straight-line motor, belong to straight line transmission motor technology field.
Background technology:
At present, the structure that reversible straight-line motor of the prior art generally all adopts the opposite solenoid of two groups of direction of windings and lamination and quoit are installed between solenoid, as the disclosed patent No. on Chinese patent literature be: 95102301.2, denomination of invention is: " all-metal reversible straight-line motor " is exactly the technical scheme of a this structural electromotor, though having, existing this reversible straight-line motor need not use permanent magnet, advantage of simple structure, but owing in lamination, increased a quoit, significantly reduced the area of lamination, thereby cause magnetic field intensity to reduce, thereby its power output is lower, and existing reversible straight-line motor is because the restriction of its structure, general all is to adopt the structure of sliding friction to move on guide rail, the operating structure of this sliding friction, inefficiency not only, but also easily wearing and tearing, thereby shortened useful life of motor.Therefore, existing reversible straight-line motor in use, its result of use still is not ideal enough.
Summary of the invention:
The objective of the invention is: provide a kind of simple in structure, operating efficiency is higher, useful life is long reversible straight-line motor, to overcome the deficiencies in the prior art.
The present invention is achieved in that it comprises metal shell (1), solenoid (3) that two groups of direction of windings on 4 plastic coil framves (2) are opposite and lamination (4), each bobbin (2) all is located between two laminations (4), and solenoid (3) and lamination (4) on plastic coil frame (2) all are contained in the metal shell (1), on bobbin (2) and lamination (4), be provided with the concentric holes of same diameter, in the hole of bobbin (2) and lamination (4), be installed with one as motor slide rails, length is greater than the hollow aluminum pipe (5) of the length of metal shell (1), bobbin (2) and lamination (4) can be gone up at hollow aluminum pipe (5) together with metal shell (1) and slide, and hollow aluminum pipe (5) is enclosed within on the solid iron staff bar (6); Also be respectively equipped with a plastic end cover (7) at the two ends of metal shell (1), and on plastic end cover (7), be provided with turning rolls (8), on turning rolls (8), be equipped with and go up the bearing roller (9) that rolls at hollow aluminum pipe (5); There is one deck oxidation processes superficial layer on the surface of hollow aluminum pipe (5).
Owing to adopted technique scheme, the present invention has cancelled the copper ring of laying in the traditional line motor between coil, this has not only increased the effective area of lamination, thereby the electromagnetic field intensity when having improved work, but also simplify the structure, simplified production technology greatly and reduced cost of manufacture, in addition, the present invention is when work, the operation of its motor on guide rail mainly is that bearing roller contacts with the guide rail rolling friction, thereby also improved the mechanical efficiency of motor greatly.Therefore, the present invention compared with prior art, that the present invention has is simple in structure, efficient is high, the advantage of long service life.
