Abstract
The invention relates to a special three-phase asynchronous motor for ZYS series compressors, which mainly adopts the technical scheme that a front end cover, a back end cover and a motor case are connected and fixed into a motor case, a motor shaft is supported and arranged in the motor case through a bearing assembly, a rotor is arranged on the motor shaft, a stator is arranged on the motor case, a fan is fixed on the motor shaft, and a wind cover is fixed on the back end cover. The invention is characterized in that the shaft end of the motor shaft extends out of the front end cover, and keys are arranged in key slots in front of the motor shaft. A circlip for hole is arranged between the bearing assembly and the front end cover, a wave form leaf spring is arranged between the bearing assembly and the back end cover, and a wiring box is connected on the stator through a screw bolt. The invention can reduce the manufacture cost and raw materials, can reduce the energy consumption, and has small size. The bearing installation and bearing locking mode can be changed according to different connection modes of the compressor and the motor for meeting the requirements of specific conditions of different compressors.
Description
Technical field
The present invention relates to a kind of ZYS series special three-phase asynchronous motor for compressor, specifically be 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 objective of the invention is to overcome above-mentioned weak point, thereby a kind of special three-phase asynchronous motor for compressor is provided, 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.
According to technical scheme provided by the invention, 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 present invention has the following advantages:
The present invention 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.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure side view of the present invention.
