Description

Novel oil seal structure

Technical Field

The utility model relates to an oil blanket equipment technical field, more specifically say, the utility model relates to a novel oil blanket structure.

Background

The oil seal is a common name of a sealing element, namely a lubricating oil seal, and is a mechanical element for sealing grease, and parts needing to be lubricated in a transmission part are isolated from a force-applying part so as not to leak lubricating oil.

The existing oil seal design of the product has the defects that the blocked path is mostly very short due to the effects, assembly and cost, and water vapor, dust and pollutants are more than the blocked part, so that the waterproof and dustproof effects are not achieved, and the oil seal effect is not obvious.

Therefore, a new oil seal structure is needed.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned defect of prior art, the embodiment of the utility model provides a novel oil blanket structure through on not changing corresponding equipment space again, has increased the path length who blocks, has also narrowed the route, has reached dustproof efficiency promptly and has also accorded with the cost requirement, very big increase the device's practicality to solve the problem of proposing in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel oil blanket structure, includes drive mechanism and oil blanket subassembly, drive mechanism's oil inlet joint has the oil blanket subassembly, the oil blanket subassembly include the casing, the side of casing is integrated into one piece to be had an extension piece, the opposite side of extending the piece is integrated into one piece to be had the shell, the inside of casing is integrated into one piece to be had the inner circle, set up the inside groove that is located on the casing between inner circle and the casing.

In a preferred embodiment, both sides of the extension block are in a chamfered state where R is zero point two.

In a preferred embodiment, the angle between the side of the extension block and the side of the housing is thirty degrees.

In a preferred embodiment, the diameter of the shell and housing has a value of fifty-one-millimeters.

In a preferred embodiment, the diameter of the extension block has a value of fifty-two and five millimeters.

In a preferred embodiment, the inner tank has a diameter value of thirty-eight and nine millimeters.

In a preferred embodiment, the oil seal assembly has a hardness in the range of fifty to ninety degrees.

The utility model discloses a technological effect and advantage:

the utility model discloses a do not change on the corresponding equipment space again, increased the path length who blocks, also narrowed the route, reached dustproof efficiency promptly and also accorded with the cost requirement, very big increase the device's practicality.
