Abstract
The utility model relates to a three-phase asynchronous motor dedicated to a compressor in ZYS series, which mainly adopts a motor shell body that is fixedly connected by a front end cover, a back end cover and a motor shell, and a motor shaft supported by a bearing component is installed in the motor shell body, and a rotator is installed at the motor shaft, and a stator is installed at the motor shell, a fan is fixed at the motor shaft, and a fan housing is fixed at the back end cover; the utility model is characterized in that: the shaft end of the motor shaft stretches out of the front end cover, and a key slot at the front of the motor shaft is provided with the key. And an elastic retainer ring for hole is arranged between the bearing component and the front end cover. A wave-shaped spring sheet is arranged between the bearing component and the back end cover. And the stator is connected with a junction box through a bolt. For the utility model, the manufacturing cost and raw materials can be reduced; the energy-consumption can be reduced, and the volume is small; according to different connecting ways of the compressor and the motor, the installing and locking ways of the bearing are changed, in order to meet requirements of different compressors under specific conditions.
Description
Technical field
The utility model relates to a kind of ZYS series special three-phase asynchronous motor for compressor, specifically is used for the drive compression machine equipment.
Background technology
In prior art, the motor great majority that compressor uses are the two poles of the earth, four utmost point motors, rotating speed is very high, originally the matching used common electric machine of compressor can not satisfy the instructions for use that compressor develops peculiar specified conditions to a certain extent, as economical with materials, cut down the consumption of energy, reduced volume, architecture advances etc.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of special three-phase asynchronous motor for compressor is provided, and can reduce manufacturing cost and raw material; Cut down the consumption of energy, volume is little; Can satisfy the instructions for use that compressor develops peculiar specified conditions.
The technical scheme that provides according to the utility model, special three-phase asynchronous motor for compressor adopts front end housing, rear end cap and motor casing to be connected into electric machine casing, motor shaft is supported by bearing assembly and is installed in the electric machine casing, rotor is installed on the motor shaft, stator is installed on the motor casing, and fan is fixed on the motor shaft, and fan housing is fixed on the rear end cap, feature is: motor shaft end stretches out front end housing, fitting key in the keyway of motor shaft front.Between described bearing assembly and front end housing circlip for hole is set.The wavy spring sheet is set between described bearing assembly and rear end cap.
Connect terminal box by bolt above the described stator.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can reduce manufacturing cost and raw material; Cut down the consumption of energy, volume is little; According to different compressors and motor connected mode, change Bearing Installation and bearing lock mode, to satisfy the requirement of different compressors specified conditions of living in.
