Description

Rotating shaft sealing ring capable of achieving rapid proofing

Technical Field

The utility model relates to a rotation axis sealing washer field especially relates to a rotation axis sealing washer that can make a design fast.

Background

The rotary shaft sealing ring, also called rotary shaft lip sealing ring, is installed between the rotary shaft and the stationary part, is used for sealing the dynamic sealing element of the equipment for preventing the leakage of lubricating oil and the invasion of external dust and sundries, is generally used for sealing the positions of a rod, a shaft, a pin, a rotary joint and the like which rotate or swing, has rotary hydraulic rotation in various industrial fields such as engineering machinery, construction machinery, automobile equipment and the like, and is a rotary sealing ring with two-way action capable of bearing the action of pressure on two sides or alternating pressure.

The existing rotary shaft sealing ring is generally manufactured by manufacturing a mold, so that the construction period or the production period is long.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior manufacturing technology and providing a rotary shaft sealing ring capable of quickly proofing.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a rotation axis sealing washer that can make a design fast, includes the oil blanket support, the inboard of oil blanket support is equipped with seal lip, perhaps opens one or many grooves at the support external diameter, places o shape circle and makes the quiet sealed effect of external diameter better.

As a further description of the above technical solution:

the front surface of the oil seal support is in a circular ring shape.

As a further description of the above technical solution:

and corners of the oil seal support adopt chamfers.

As a further description of the above technical solution:

and one side of the sealing lip, which is far away from the oil seal support, is uniformly provided with a circular groove.

As a further description of the above technical solution:

the front surface of the sealing lip is in a circular ring shape, and an O-shaped ring is tightly attached to the inner side of the circular ring shape of the sealing lip.

The utility model has the advantages that:

1. compared with the prior art, the utility model discloses in, seal lip and metal support in the rotation axis sealing washer are connected, and the seal lip heat dissipation of being convenient for has increased the live time of rotation axis sealing washer indirectly, is particularly useful for the environment of new energy automobile high speed and high temperature.

2. Compared with the prior art, the sealing ring does not need to be manufactured into a mold, the bracket is machined through turning, then the production process of the product can be completed through press mounting, the construction period is greatly shortened, and convenience is brought to ultra-short-time proofing of part of customers.

The working principle is as follows: when using this kind of rotation axis sealing washer that can make a design fast, the inboard of oil blanket support adopts to fill polytetrafluoroethylene seal lip, and the external diameter of seal lip is held in the inside of oil blanket support, then installs this rotation axis sealing washer in the seal seat downthehole, and the lip of seal lip makes the lip of seal lip hug closely sealed face and realize sealed effect under the effect of memory effect.
