Abstract
The utility model discloses an electric motor, particularly an electric motor adopting a single side bearing for hanging and support. The electric motor comprises a rear end cover, a winding stator core, a shaft and a rotor. A wave-shaped washer is arranged between two bearings, and a cover plate of a bearing chamber is fixed to the rear end cover by a chamfer head screw. A baffle plate is additionally arranged outside the bearings, and a shim can also be arranged between the two bearings; the wave-shaped washer is arranged between the bearing and the rear end cover and between the bearing and the cover plate of the bearing chamber. The utility model has the advantages of simple structure, and convenient operation and installation. The electric motor can not generate jumping noise during frequent starting and clockwise rotation or counterclockwise rotation.
Description
The utility model relates to a kind of motor, particularly a kind of motor that adopts monolateral supporting frequent starting and rotating.
At present, because motor rotor and stator and winding magnetic field center are inevitable asymmetric, rotor can produce the play phenomenon because of magnetic pull, particularly because there is play in bearing enclose, can produce noise because of the play of rotor magnetic pull between two bearings.Although occurred a kind of AC low speed synchronous electric motor on the market with anti-shocking base, the patent No. is: 99,217,969 6, this motor can obtain the utmost point slow-speed of revolution, and be provided with the composite shock-absorbing seat, noise is reduced, but be used for the motor of this frequent starting of washing machine use, still exist noise bigger, baroque disadvantage.
The purpose of this utility model just is to solve the drawback of above-mentioned existence, provides a kind of motor simple in structure can not produce the motor of the monolateral bearing suspension supporting of play noise when frequent starting and rotating.
The technical solution of the utility model is achieved in that this motor comprises rear end cap, winding stator core, axle, rotor are arranged, between two bearings, be provided with wave washer, the bearing chamber cover plate is fixed on the rear end cap by sunk screw, the outside of bearing is provided with a baffle plate in addition, also can be provided with pad between the two bearings, and wave washer is located between bearing and rear end cap and bearing and the bearing chamber cover plate.
The utility model is simple in structure, and fitting operation is convenient, and motor can not produce the play noise when frequent starting and rotating, and motor applications is wider general.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of bearing chamber shown in Figure 1;
Fig. 3, Fig. 4, Fig. 5 are the partial enlarged drawing of the other three kinds of bearing chambers of the utility model;
As shown in the figure, this motor comprises rear end cap 1, winding stator core 2 is arranged, axle 6, rotor 8, rear end cap 1 is used for fixing stator line bag and lays bearing, has winding stator core 2 to produce magnetic field, magnetic field, axle 6, connect rotor and rear end cap 1 and be used to hang fixed rotor, rotor 8 is used for cutting magnetic line, produces turning moment, is provided with wave washer 3 between two bearings 4, be used to slow down the impact of rotor 8, reduce noise, bearing chamber cover plate 7 is fixed on by sunk screw and is used for fastening bearing 4 on the rear end cap 1, and the outside of bearing 4 is provided with a baffle plate 5 in addition and is used to hang fixed rotor.Also can be provided with pad 9 between the two bearings 4, and wave washer 3 is located between bearing 4 and rear end cap 1 and bearing 4 and the bearing chamber cover plate 7.The effect of pad 9 is to avoid contacting between two bearings, reduces noise.Adopt this structure, fitting operation is convenient, and motor can not produce the play noise when frequent starting and rotating, especially for motor for washer.
