Abstract
The invention relates to a traction machine permanent magnetism motor, comprising a hub, a traction sheave, a magnet yoke and a tile-shaped permanent magnet, wherein the tile-shaped permanent magnet is adhered on the inner surface of the magnet yoke; the traction machine permanent magnetism motor is characterized in that the hub and the traction sheave are formed by processing whole nodular cast iron; the magnet yoke is fixed on the hub axially via a screw; and the magnet yoke materials use soft magnetic materials. Compared with the prior art, the invention has the advantage of simple processing, easily ensures jumping of the traction sheave groove and the outer cylindrical surface of the hub, ensures good magnetic conduction property and can not lower electric property of the motor.
Description
Technical field
The present invention relates to a kind of traction machine permanent magnetism motor that on elevator, uses.
Background technology
Traction machine permanent magnetism motor mainly is made up of wheel hub, traction sheave, yoke, permanent magnet four parts, but different connected modes has different structures, now commonly used have followingly have three kinds:
First kind: traction sheave and wheel hub all are the spheroidal graphite cast-iron castings, traction sheave is installed in the front end of wheel hub, yoke is installed in the rear end of wheel hub, yoke is a soft magnetic material, structure such as Fig. 1, the shortcoming that this structure exists is: wheel hub, traction sheave, yoke all need separately machine work, can not exceed standard for guaranteeing to beat after traction sheave race and wheel hub external cylindrical surface assemble, usually need higher processing precision, this has just caused the processing cost increase.
Second kind: wheel hub and yoke design are one, and adopt the spheroidal graphite cast-iron casting, and traction sheave is assemblied in the front end of wheel hub, and as Fig. 2, there are two problems in this structure: 1 uses the yoke magnetic conductivity of spheroidal graphite cast-iron relatively poor, bigger to the influence of motor electric property; 2 wheel hubs, traction sheave all need higher processing precision, could guarantee to beat after the assembling of traction sheave race and wheel hub external cylindrical surface can not exceed standard, and has the high problem of processing cost.
The third: Chinese patent 200820102538.3 disclosed a kind of p-m rotors, wheel hub, traction sheave, yoke all adopt spheroidal graphite cast-iron to be cast into one, structure as shown in Figure 3, this structure can make traction sheave race and wheel hub external cylindrical surface beat very little with the method for time processing, but, the magnetic conductivity of spheroidal graphite cast-iron is relatively poor, and the motor electric property is descended.
Summary of the invention
The object of the present invention is to provide a kind of handling ease, guarantee that easily traction sheave race and wheel hub external cylindrical surface beat, and can not reduce the traction machine permanent magnetism motor of motor electric property.
The present invention is achieved in that and comprises wheel hub, traction sheave, yoke, tile permanent magnet, the tile permanent magnet is close to the inner surface of yoke, its special feature is that wheel hub and traction sheave adopt whole spheroidal graphite cast-iron to process, yoke is fixed on the wheel hub by screw axial, and the yoke material is a soft magnetic material.
The present invention is because wheel hub and the monoblock cast of traction sheave employing spheroidal graphite cast-iron are one, fixedly connected with the soft magnetic material yoke by screw then, therefore, has handling ease, assurance traction sheave race and wheel hub external cylindrical surface are beated easily, guarantee that simultaneously yoke has good magnetic property, can not reduce the advantage of motor electric property.
Description of drawings
Fig. 1 is first kind of existing traction machine permanent magnetism motor structure half sectional view;
Fig. 2 is second kind of existing traction machine permanent magnetism motor structure half sectional view;
Fig. 3 is the third existing traction machine permanent magnetism motor structure half sectional view;
Fig. 4 is a structure half sectional view of the present invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
As shown in Figure 4, its structure of p-m rotor of the present invention mainly constitutes the permanent magnetism p-m rotor by traction sheave 1, wheel hub 2, yoke 4, tile permanent magnet 5, yoke 4 is axially fixed on the wheel hub 2 by screw 3, permanent magnet 5 is close to the inner surface of yoke, and the magnetic pole utmost point of adjacent two tile permanent magnets 5 is on the contrary.
Below the fixedlying connected of wheel hub 2 and yoke 4, be provided with positioning boss 9, accurately be connected and fixed to make things convenient for wheel hub 2 and yoke 4.
Above-mentioned traction sheave 1 and wheel hub 2 adopt whole spheroidal graphite cast-iron to process, and there is through hole 8 at the center.
Above-mentioned yoke 4 materials that are connected with wheel hub 2 are soft magnetic material, for example: Q235, No. 20 steel etc.
The utility model is cast into an integral body with traction sheave 1 and wheel hub 2, can whole process, and traction sheave race 7 and wheel hub periphery 6 beating degrees guarantee easily.
Yoke 4 materials are soft magnetic material, and magnetic conductivity is good, help to improve the motor electric property.
