Abstract
The utility model relates to a magnetic float type bearing motor, which is composed of a motor bedplate, a casing, an end cover, a shaft, a bearing cover, a stator, a rotor, bolts and a bearing. The utility model is characterized in that the shaft of the motor, the end cover and the bearing cover are all made of non-metallic materials with high strength and abrasion resistance. Both ends of the shaft are respectively provided with a rotating shaft part of a fixed magnetic bearing, and a corresponding magnetic bearing part which is fixed by the end cover and the bearing cover and is matched with the rotating shaft part of the magnetic bearing. The outer edge of the magnetic bearing part is provided with a clamping hoop which is made of non permeability magnetic materials. The two bearing parts are magnets with same magnetism. The rotor which is fixed on the shaft and the stator which is fixed on the casing lie in the state of air friction of a gap of a magnetic float space. The shaft of the utility model is floated by magnetic force, therefore no lubrication oil is filled. The utility model has the advantages of small friction, low noise and long and stable operation.
Description
Technical field
The utility model relates to a kind of maglev type bearing electric machine.
Background technology
At present, motor generally all adopts metal bearing or watt shaft type engine oil lubrication rotational structure, its pivoting friction position lubricating oil of must annotating, to increase lubrification, reduce frictional resistance, reduce rotational noise simultaneously, this will be regular or irregular motor is checked and keeped in repair, cause bearing wear in case lubricating oil runs off, and then burn out stator or rotor, bring burden and trouble to the user.
The utility model content
The purpose of this utility model be to improve the shortcoming of prior art and provide a kind of without lubricating oil, friction is little, noise is low, can guarantee the maglev type bearing electric machine that it moves steadily in the long term.
For achieving the above object, the utility model is taked following design: by electric machine stand, casing, end cap, axle, bearing cap, stator, rotor, bolt, in the motor that bearing etc. are formed, the axle of motor, end cap, bearing cap all adopts high strength, anti abrasive nonmetallic materials, the two ends of axle have the rotating shaft part of fixing magnetic bearing and the magnetic bearing part that the rotating shaft with above-mentioned magnetic bearing by end cap and bearing cap fixed corresponding with it partly is complementary respectively, described magnetic bearing part outer rim is provided with the clip of non-magnet material, to increase its intensity, described two bearings partly is with magnetic magnet, because row tears power open, form the floating spatial joint clearance of a magnetic, make rotor that is fixed on the axle and the stator that is fixed on the casing be in the minimum state operation down of air friction that magnetic floats spatial joint clearance, therefore the operating state noise is little, the lubricating oil of needn't annotating, also can check frequently and keep in repair, motor can move steadily in the long term.In order to increase the supporting force of maglev type bearing, can be designed to curved surface with the corresponding surface of magnetic magnet.The described curved surface that is designed to the corresponding surface of magnetic magnet is protruding, concave cone shape curved surface.
The utility model arbor is by magnetic levitation, thus the lubricating oil of need not annotating, rub little, noise is low, can move steadily in the long term.
