Description

High-speed wear-resistant oil seal

Technical Field

The utility model relates to a sealed technical field especially relates to a high-speed wear-resisting oil blanket.

Background

Oil seals are a common term for seals, simply the seal of lubricating oil. It is used to seal grease (oil is the most common liquid substance in transmission systems, also refers to the general liquid substance mechanical element, it separates the parts needing lubrication from the output parts, and does not let the lubricating oil leak.

The rotary oil seal is an indispensable element for a lubricating medium of a sealed bearing, belongs to an easily-consumed product, and provides requirements of higher rotating speed, higher rotating speed and longer service life for the rotary oil seal along with the rapid development of the industry.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving and having the seal lip to gather a large amount of heats among the prior art to rubber's ageing and wearing and tearing lead to the oil blanket to become invalid fast, can't satisfy the shortcoming of long life's requirement, and the high-speed wear-resisting oil blanket that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a high-speed wear-resisting oil blanket, includes rubber, install first metal framework in the rubber, be equipped with the waist on the rubber, the spring groove has been seted up to one side of rubber, and the spring is installed to the spring inslot, and one side of rubber is equipped with the PTFE layer.

Preferably, the PTFE layer is made of PTFE materials, the PTFE materials are fixedly arranged on the surface of the rubber sealing lip through coating adhesives, and due to the fact that the PTFE materials are low in friction coefficient, good in self-lubricating property, good in oil resistance, almost all chemical resistance and high and low temperature resistance, when the rubber sealing lip works for a long time under high speed and high pressure, the temperature rise is kept low, the aging and abrasion of the sealing lip are relieved, and the service life of the oil seal is prolonged.

Preferably, the first metal framework is coated with an adhesive, and the first metal framework is fixedly installed in the rubber through the adhesive.

Preferably, the rubber comprises an outer shoulder, and the outer shoulder internally wraps the first metal framework and supports the first metal framework.

The utility model discloses in, a high-speed wear-resisting oil blanket, including rubber, PTFE, metal framework and spring. Rubber is the main part material of outer shoulder and seal lip, and the design of the waist of reinforcing can bear the high pressure, PTFE and rubber surface complex form the main working face of seal lip, it plays the supporting role to enclose in the outer shoulder in the metal framework, the spring is installed in the spring groove of lip after the oil blanket shaping, provides long-term effectual radial force.

The utility model relates to a rationally, at high speed, the long-time during operation under the high pressure, it is lower to keep the temperature rise to slowed down seal lip's ageing and wearing and tearing, the life of extension oil blanket.
