The invention relates to a bearing configuration structure of a high-voltage three-phase asynchronous motor. The bearing configuration structure consists of a left end part and a right end part, wherein the left end part comprises a left oil thrower, a left external bearing cover, a left end cover and a left internal bearing cover; and the right end part comprises a right internal bearing cover, a right end cover, a pre-tightening spring, a right external bearing cover and a right oil thrower. The bearing configuration structure is characterized in that: in the left end part, a left deep groove ball bearing is arranged on the left end cover, the two sides of the left deep groove ball bearing is fixed by the left external bearing cover and the left internal bearing cover, and the left oil thrower is arranged between the left external bearing cover and the left deep groove ball bearing; and in the right end part, a right deep groove ball bearing is arranged on the right end cover, the two sides of the right deep groove ball bearing is fixed by the right external bearing cover and the right internal bearing cover, and the right oil thrower and the pre-tightening spring are arranged between the right external bearing cover and the right deep groove ball bearing. The bearing configuration structure has the advantages of simple, compact and reasonable structure, convenient operation, short processing time, low cost, low noise, high processibility, high reliability and convenient installation and maintenance.
Description
technical field [0001] The invention relates to a bearing configuration of a high-voltage three-phase asynchronous motor, in particular to a bearing configuration structure of a three-phase asynchronous motor with simple structure, low cost and convenient assembly. Background technique [0002] At present, the motor industry is developing rapidly, and the bearing configuration of high-voltage three-phase asynchronous motors is also constantly changing. Due to the need to continuously reduce the cost of enterprise products, reduce the temperature of motor bearings, reduce noise, etc., the existing bearing configuration has gradually become impossible. Adapt to customer requirements. In the prior art, the bearing configuration structure of the three-phase asynchronous motor includes two ends, the left end is a short cylindrical bearing, the upper end of the short cylindrical bearing is connected to the end cover, the left side of the short cylindrical bearing is fixed by the ...
