Description

Long-acting axial surface oil seal

Technical Field

The utility model belongs to the technical field of motor shaft assembly, and particularly relates to a long-acting axial surface oil seal.

Background

The common mechanical equipment has sealed casing in two ends, and the shaft passes through the hole in the center of the casing and has some interval to the casing for the shaft to rotate freely inside the hole. However, because of the gaps, the protection level is not very high, dust, rainwater and even small sand particles can enter the mechanical equipment and be adsorbed in the lubricating oil at the bearing, so that the running performance of the mechanical equipment is reduced, the noise is increased, and the equipment is stopped. The high protection axial plane oil blanket of current patent number CN202021545469.0 includes and constitutes by ring form metal casing and rubber circle, and it is installed on the mechanical equipment shell, and the ring internal diameter and the mechanical equipment axle interference fit of ring form metal casing are equipped with circumference on the ring inner edge of ring form metal casing and arrange the outside recess of opening, the lateral wall of recess is crooked to the inboard side, the rubber circle includes inner circle and lip, the inner circle with recess shape size the same, the inner circle is fixed in the recess. The rubber circle lip of current axial surface oil blanket is located the outside of recess, along with the increase of revolving force, can reduce the lip to the contact pressure of sealed face, long-time operation, and the protective effect reduces.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems and provide a long-acting type shaft surface oil seal, so that the change of a sealing contact structure of the shaft surface oil seal is realized, and the long-acting protection effect is achieved. In order to achieve the purpose, the technical scheme of the utility model is as follows:

the long-acting axial surface oil seal comprises an annular body, an outer edge ring which is arranged on the periphery of the annular body and forms a step structure with the annular body, and a sealing ring component which is embedded into the annular body; the inner periphery of the ring body is provided with inner flanges arranged along the circumferential direction, the sealing ring assembly comprises supporting legs connected with the ring body and rubber rings respectively limited on two sides of the supporting legs, a lip of each rubber ring close to the inner flanges extends towards the inner flanges and is arranged, and a lip of each rubber ring close to the outer edge ring extends towards the outer edge ring.

Specifically, a reinforcing part is arranged at the circumferential connecting part of the inner flange and the annular body.

Specifically, the supporting legs are of T-shaped structures, and an installation groove for accommodating the rubber ring is formed between the supporting legs and the annular body.

Specifically, the annular body and the outer edge ring are integrally connected.

Specifically, the annular body and the outer edge ring are made of metal materials.

Compared with the prior art, the long-acting axial surface oil seal has the beneficial effects that:

the supporting legs of sealing washer subassembly connects the ring form for the rubber circle is spacing in the mounting groove, and the rubber circle of one side is used for on the motor shaft of the inner circle position that is close to interior flange in the sealing, and the rubber circle of opposite side is used for on the motor shaft of the outer lane position that is close to the outer fringe ring in the sealing, guarantees the stability of the rubber circle mounted position of both sides simultaneously, makes the sealed contact surface increase contact pressure of the lip of rubber circle, reaches the dual sealed effect, is applicable to long-time motor shaft work operation.

Detailed Description

The technical solutions in the embodiments of the present invention are described clearly and completely below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

Example (b):

referring to fig. 1 to 3, the long-acting axial surface oil seal of the present embodiment includes an annular body 1, an outer rim 2 disposed at the periphery of the annular body 1 and forming a step structure with the annular body, and a sealing ring assembly embedded in the annular body 1.

In this embodiment, the annular body 1 and the outer rim ring 2 are integrally connected and made of metal.

The inner periphery of the annular body 1 is provided with an inner rib 11 arranged along the circumferential direction, and a reinforcing part 12 is arranged at the circumferential connection part of the inner rib 11 and the annular body 1.

The sealing washer subassembly is including connecing the supporting legs 3 of annular body 1, limiting respectively in the rubber circle 4 of supporting legs 3 both sides, and the lip 41 of the rubber circle 4 that is close to interior flange 11 extends the setting towards interior flange 11, and the lip 41 of the rubber circle 4 that is close to outer limbers ring 2 extends the setting towards outer limbers ring 2.

The supporting leg 3 is a T-shaped structure, and an installation groove 42 for accommodating the rubber ring 4 is formed between the supporting leg 3 and the annular body 1.

When using this embodiment, the supporting legs 3 of sealing washer subassembly connect the ring body 1, make rubber ring 4 spacing in mounting groove 42, the rubber ring 4 of one side is used for on the motor shaft of the inner circle position that is close to interior flange 11 in the sealed, the rubber ring 4 of opposite side is used for on the motor shaft of the outer lane position that is close to outer fringe ring 2 in the sealed, guarantee the stability of the rubber ring 4 mounted position of both sides simultaneously, make the sealing contact surface increase contact pressure of lip 41 of rubber ring 4, reach the dual sealed effect, be applicable to long-time motor shaft work operation.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
