Abstract
The utility model relates to a magnetic float bearing motor which is composed of a motor base, a casing, an end cover, a shaft, a bearing cover, a stator, a rotor, a bolt and a bearing, wherein both ends of the shaft are respectively provided with a fixed magnetic bearing part in a shape of a convex cone and a corresponding bearing part of a shape of a convex cone, wherein the bearing part of a shape of a concave cone is fixed by the end cover and the bearing cover and is matched with the magnetic bearing part in a shape of a convex cone, and the bearing part of a shape of a concave cone and the magnetic bearing part in a shape of a convex cone have the same magnetic property partially. The utility model has the advantages that noise in an operational state is small, lubricating oil is unnecessary to fill, the motor does not need to be maintained and repaired frequently, and the motor can run stably for a long time.
Description
The utility model relates to a kind of maglev type bearing electric machine.
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 purpose of this utility model is to improve the shortcoming of prior art and a kind of maglev type bearing electric machine is provided, and it is without lubricating oil, and frictional dissipation is little, and noise reduces greatly, can guarantee that motor moves steadily in the long term.
The purpose of this utility model is to realize like this, 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 respectively fixing male conical magnetic bearing partly and corresponding with it have fix by end cap and bearing cap, the concave cone shape magnetic bearing part that partly is complementary with above-mentioned male conical magnetic bearing, described concave cone shape magnetic bearing part outer rim is provided with the clip of a non-magnet material, to increase its intensity, and 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 be checked and be keeped in repair frequently.Motor can move steadily in the long term.
The utility model is described in further detail in conjunction with the accompanying drawings to quote embodiment below.
Fig. 1 is the utility model structural representation
Embodiment:
By support 1, shell 2, stator 3, rotor 4, axle 5, bearing cap 6, end cap 7, double-screw bolt 8, in the motor that bearing 9 is formed, one end of axle 5 has a ladder section 51, a male conical magnetic bearing part 91 that is adhesively fixed that is complementary with it is arranged on it, and correspondingly with it have by the fixing concave cone shape magnetic bearing that partly is complementary with above-mentioned male conical magnetic bearing of end cap and bearing cap partly 92, the other end of axle 5 is a stepped shaft part 52, the male conical magnetic bearing part 93 that has another to be adhesively fixed at the axle journal position, and should have by the fixing concave cone shape magnetic bearing part 94 that partly is complementary with above-mentioned male conical magnetic bearing of end cap and bearing cap relatively with it, in concave cone shape magnetic bearing part 92,94 outer rims have an aluminium circular boop 10, to increase its intensity, prevent its spalling.Above-mentioned axle, end cap, bearing cap are by nonmetallic materials such as nylon 66 glass fibres casting extrusion forming.
