Abstract
The utility model discloses an efficient axial surface oil seal which comprises an annular body, an inner flange, an outer flange, a turnover edge and a sealing ring, wherein the inner flange is arranged on the inner ring of the annular body in the circumferential direction; the inner lip of the sealing ring extends towards the inner flange, and the outer lip of the sealing ring extends towards the flanging edge. The utility model realizes the change of the sealing contact structure of the shaft surface oil seal and has high-efficiency protection performance.
Description
Technical Field
The utility model belongs to the technical field of motor shaft assembly, and particularly relates to an efficient shaft 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 an efficient shaft surface oil seal, so that the sealing contact structure of the shaft surface oil seal is changed, and the efficient protection performance is realized. In order to achieve the purpose, the technical scheme of the utility model is as follows:
the efficient axial surface oil seal comprises an annular body, an inner flange arranged on the inner ring of the annular body in the circumferential direction, an outer flange arranged on the outer ring of the annular body in the circumferential direction, a flanging edge arranged on the edge of the outer flange in the circumferential direction, and a sealing ring limited between the inner flange and the outer flange; the inner lip of the sealing ring extends towards the inner flange, and the outer lip of the sealing ring extends towards the flanging edge.
Specifically, the annular body, the inner flange, the outer flange and the turned edge are integrally connected and formed.
Specifically, the circumferential edge of the inner flange is provided with a bending part facing the ring body, and an installation groove for limiting the sealing ring is formed between the bending part and the ring body.
Specifically, the inboard circumference of outer flange is equipped with the arc convex part, the sealing washer supports with the corresponding laminating of arc convex part and leans on.
Compared with the prior art, the high-efficiency axial surface oil seal has the beneficial effects that:
through flange in setting up on the ring body, form the mounting groove of spacing sealing washer, cooperate the arc convex part simultaneously for the sealing washer closely installs on the ring body, and the inner lip and the outer lip of sealing washer are towards both sides respectively, and sealed the supporting on the motor shaft, and when the rotatory atress of sealing washer, the contact pressure increase of the sealed face of inner lip and outer lip has dual seal effect, realizes high-efficient sealing performance.

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. 1-3, the present embodiment is a high-efficiency axial surface oil seal, which includes an annular body 1, an inner flange 2 disposed in the circumferential direction of an inner ring of the annular body 1, an outer flange 3 disposed in the circumferential direction of an outer ring of the annular body 1, a flanging edge 4 disposed in the circumferential direction of an edge of the outer flange 3, and a sealing ring 5 limited between the inner flange 2 and the outer flange 3; the inner lip 51 of the sealing ring 5 extends towards the inner flange 2 and the outer lip 52 of the sealing ring 5 extends towards the flange 4.
In this embodiment, the annular body 1, the inner flange 2, the outer flange 3, and the turned edge 4 are integrally connected and formed and made of metal.
The circumferential edge of the inner flange 2 is provided with a bending part 21 facing the ring body 1, and an installation groove 53 for limiting the sealing ring 5 is formed between the bending part 21 and the ring body 1.
The inner circumference of the outer flange 3 is provided with an arc-shaped convex part 31, and the sealing ring 5 is correspondingly attached to and abutted against the arc-shaped convex part 31.
When using this embodiment, through flange 2 in setting up on ring body 1, form mounting groove 53 of spacing sealing washer 5, cooperate arc convex part 31 simultaneously for sealing washer 5 closely installs on ring body 1, and the interior lip 51 and the outer lip 52 of sealing washer 5 are towards both sides respectively, and sealed the supporting on the motor shaft, and when sealing washer 5 rotatory atress, the contact pressure increase of the sealed face of interior lip 51 and outer lip 52 has dual sealed effect, realizes high-efficient sealing performance.
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.
