Description

Novel motor rotating shaft oil seal

Technical Field

The utility model belongs to the technical field of the oil blanket and specifically relates to a novel motor shaft oil blanket is related to.

Background

Oil seals are a common term for seals, simply the seal of lubricating oil. The oil seal is a mechanical element for sealing grease, separates a part needing lubrication in a transmission part from a force-exerting part, and prevents lubricating oil from leaking, but a common oil seal cannot achieve good sealing performance, and the lubricating oil can leak out when the oil seal is frequently used.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.

A novel motor rotating shaft oil seal comprises an oil seal body, wherein the oil seal body is divided into an inner ring and an outer ring, the inner ring of the oil seal body is provided with a motor rotating shaft, the motor rotating shaft is tightly attached to the inner ring of the oil seal body, the lower wall of the inner ring of the oil seal body is provided with a backflow line, the backflow line is in a raised triangle shape and is in direct contact with the motor rotating shaft, an annular inner cavity is arranged between the inner ring and the outer ring of the oil seal body and is communicated with the upper end of the oil seal body, the outer wall and the inner wall of the annular inner cavity are provided with a plurality of concave grooves, the concave grooves are in the vertical direction, the concave grooves are formed from the upper end of the oil seal body to the lower end of the annular inner cavity, spring pieces are arranged in the annular inner cavity and are integrally annular, the spring pieces are in continuous bending waves at annular positions, the convex positions of the outer sides of the spring pieces are clamped with the concave grooves in the outer wall of the annular inner cavity, and the convex positions of the inner sides of the spring pieces are clamped with the concave grooves in the inner wall of.

As a further aspect of the present invention: the section of the annular inner cavity is concave.

As a further aspect of the present invention: the height of the spring piece is smaller than that of the annular inner cavity.

Compared with the prior art, the beneficial effects of the utility model are that:

1. accomplish oil blanket outer lane through the effect of spring leaf and closely cooperate with the motor inner wall, the oil blanket inner circle closely cooperates with motor shaft, accomplishes the effect that the leakproofness is good.

2. The spring piece is fixed with the oil seal body under the action of the concave groove, and the position of the spring piece cannot be changed due to high-speed rotation of the motor rotating shaft.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
