Problems solved by technology

[0002] The output end of the motor is provided with a shaft seal structure. The existing shaft seal structure at the output end of the motor is a radial shaft seal, which is arranged on the left side of the bearing. The felt ring embedded in the middle is closely matched with the outer wall of the motor shaft. This radial shaft seal has a simple structure, but once the felt ring wears out, the sealing performance will decrease. There is only one seal. Once the sealing performance decreases, the grease for bearing lubrication will be heated. Finally, it flows out directly from the gap between the felt ring embedded in the radial concave ring groove of the inner hole of the left end cover and the outer wall of the motor shaft, thereby deteriorating the lubrication condition of the bearing

Abstract

The invention discloses a ship motor front end combined shaft seal. The ship motor front end combined shaft seal is arranged at the front end of a motor and composed of a radial shaft seal and an axial shaft seal. The radial shaft seal is composed of a left end radial shaft seal body and a right end radial shaft seal body which are arranged at the left end and the right end of a bearing. The leftend radial shaft seal body is formed through tight fit of a felt ring I and the outer wall of a motor shaft, wherein the felt ring I is embedded in an inner hole radial U-shaped ring groove of a leftend cover which is located on the left side of the bearing and is in clearance fit with the motor shaft. The right side of a right end cover on the motor shaft is sleeved with an oil slinger rotatingalong with the motor shaft. The right end radial shaft seal body is formed through tight fit of a felt ring II and the outer wall of the motor shaft, wherein the felt ring II is embedded in an inner hole radial U-shaped ring groove of the right end cover which is located on the right side of the bearing and is in clearance fit with the motor shaft. The ship motor front end combined shaft seal is further characterized in that the right side of the right end cover is provided with the axial shaft seal, wherein the axial shaft seal is formed through sleeving of the oil slinger and an axial U-shaped ring groove of the right end cover. The combined shaft seal is composed of the dual radial shaft seal bodies and the axial shaft seal, and the sealing performance is good.

Description

technical field [0001] The invention relates to a shaft seal structure, in particular to a shaft seal structure at an output end of a motor. Background technique [0002] The output end of the motor is provided with a shaft seal structure. The existing shaft seal structure at the output end of the motor is a radial shaft seal, which is arranged on the left side of the bearing. The felt ring embedded in the middle is closely matched with the outer wall of the motor shaft. This radial shaft seal has a simple structure, but once the felt ring wears out, the sealing performance will decrease. There is only one seal. Once the sealing performance decreases, the grease for bearing lubrication will be heated. Finally, it directly flows out from the gap between the felt ring embedded in the radial concave ring groove of the inner hole of the left end cover and the outer wall of the motor shaft, thereby deteriorating the lubrication condition of the bearing.
