Abstract

Presently, the aware magnetic suspension bearing, radial turning bearing and axial thrust bearing are manufactured and installed respectively and the large-size motor's shaft is solid while its cost is high and the material consumption is big and manufacturing process is difficult. In order to overcome the defect of the rotating mechanic of the existing magnetic suspension bearing and its loading, the utility model provides a magnetic suspension radial, axial, sliding and thrusting new bearing and its hollow cylinder-shaped shaft motor loaded. The technical proposal adopted by the utility model for solving the technical problem is as follows: First, make the magnetic suspension bearing into axial, radial, thrusting, and sliding two-utility bearing with its manufacturing methods as that: one of the two relative magnetic poles with same magnet suited on the shaft and insulated by magnetic-proof material is to be made taper-dais and fixed on the shaft and the other is made as taper-dais bushing and fixed on the end cover of the rotation mechanic, thus, the whole manufacturing process is completed; second, make the shaft of the rotator (motor) into hollow cylinder-shaped shaft.

Description

The hollow cylinder shaft motor of magnetic-suspension axial radial thrust sliding bearing and carrying thereof

Affiliated technical field

The utility model relates to the rotary machine of a kind of magnetic suspension bearing and carrying thereof.

Background technique

At present, known magnetic suspension bearing, radially rotary bearing and axial thrust bearing are all manufactured respectively, are installed respectively, and the axle of large-size machine is a solid shaft, manufactures the cost height, and spillage of material is big, and manufacture difficulty is big, maintenance difficult, operating cost height.

Summary of the invention

In order to overcome the deficiency of the rotary machine that has magnetic suspension bearing and carrying thereof now, the utility model provides a kind of magnetic suspension radially, axially, the hollow cylinder axle favourable turn of slip, thrust, dual-purpose novel bearing and carrying thereof.

The technological scheme that its technical problem that solves the utility model adopts is: 1, magnetic suspension bearing make axially, radially, thrust, slip, dual-purpose novel bearing, concrete manufacture method is,, two magnetic poles relative, same magnetic on the axle, that insulated by NULL being enclosed within are made taper type and are fixed on the axle, another makes the shape of frustum cover, be fixed on the end cap of rotary machine, promptly finished the manufacturing installation process of this bearing.2, the axle of favourable turn (motor) is manufactured the hollow cylinder profile shaft get final product.

The beneficial effects of the utility model are, simplified cartridge type axle favourable turn and magnetic suspension bearing manufacturing, install, pick up repair, service procedure and process, reduced manufacture cost, increased the function and the Applicable scope of magnetic suspension bearing.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 be the utility model magnetic-suspension axial, radially, the sectional view of the hollow cylinder shaft motor of thrust, slip, difunctional bearing and carrying thereof.

Among the figure 1, motor hollow cylinder profile shaft, 2, overcoat in the magnetic insulation of magnetic suspension bearing, 3, be assemblied in the tapered sleeve type magnetic pole on the electric motor end cap, 4, be assemblied in taper type magnetic pole on the motor shaft, 5 electric motor end caps, 6 motor housings (support), 7, motor stator, 8 rotors.

Embodiment

In Fig. 1, rotor (8) both sides at motor, on the hollow cylinder profile shaft (1), a frustum point is installed outwardly respectively, is had the taper type magnetic pole (4) of cover in the magnetic insulation, corresponding taper type magnetic pole (4), a tapered sleeve type magnetic pole (3) is installed respectively in the end cap of motor both sides, (magnetic pole 3 is mutually identical with the utmost point of magnetic pole 4) is installed in electric motor end cap (5) on the motor housing (6), just finished manufacturing of the present utility model, installation process.
