Description

Anti-freezing oil seal

Technical Field

The utility model relates to an oil blanket technical field especially relates to an oil blanket prevents frostbite.

Background

The oil seal is a mechanical element for sealing oil, and separates a part needing lubrication in a transmission part from a force-applying part, so that the lubricating oil is prevented from leaking. The oil seal used in the engine is used between the shaft and the hole part, prevents lubricating oil in the engine from leaking outwards from the shaft hole, and prevents pollutants such as external dust, impurities, water and the like from entering the parts or components in the engine.

In some special extreme cold environments, the rubber part of the oil seal is easy to reduce the practical performance due to too low temperature, and the problems of oil leakage and the like are caused.

SUMMERY OF THE UTILITY MODEL

For overcoming the problem that exists among the prior art, the utility model provides an oil blanket prevents frostbite.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an anti-freezing oil seal, includes rubber body, inside the inlaying of rubber body has self-heating exoskeleton and self-heating inner frame, three horn mouths have been seted up at the rubber body top, three horn mouths have been seted up down to the rubber body bottom.

Preferably, the self-heating outer skeleton and the self-heating inner skeleton are internally provided with an electrochemical reaction device, and heat is generated through internal electrochemical reaction.

Preferably, an inner boss is arranged at the upper end of the inner ring of the rubber body.

Preferably, the lower end of the inner ring of the rubber body is provided with a protruding ring.

Preferably, an outer upper lug boss is arranged at the upper end of the outer ring of the rubber body.

Preferably, the lower end of the outer ring of the rubber body is provided with an outer lower boss.

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

an electrochemical reaction device is arranged in a self-heating outer framework and a self-heating inner framework, heat is generated through internal electrochemical reaction, and the anti-freezing oil seal has an anti-freezing effect under extreme severe cold working conditions.
