Technical Field

The invention relates to a sliding bearing motor sealing structure for protection grade IP56, and belongs to the field of motor protection.

Background

With the development of the times, the power requirement on the motor is higher and higher nowadays, the rotating speed requirement is higher and higher, and the rolling bearing adopted by the common motor cannot meet the use requirement of the motor due to the structure, price and the like, so the sliding bearing is adopted.

Due to the structure of the sliding bearing, the protection of the shaft through part of the sliding bearing can only reach IP55, and the protection cannot meet the requirements of motors used in some special places (such as offshore platforms). In order to solve the problem, a novel sealing structure is designed, the sealing of the through part of the shaft is solved, the protection grade of the sliding bearing motor reaches IP56, and the use requirement of the motor is met.
