Description

High-pressure rotary sealing ring structure

Technical Field

The utility model relates to the field of machinery, in particular to a high-pressure rotary sealing ring structure.

Background

When the gearbox works, lubricating oil liquid for lubricating the gear of the gearbox is easy to leak to the outside through the joint of the shaft neck and the shell, so that the oil level in the lubricating oil tank is slowly reduced, the running safety of a unit is influenced by long-term running, and the reliability and the service life of the spraying device are greatly reduced. Conventional seals, such as O-rings, are not sufficient to provide a complete seal and may also affect the efficiency of rotation of a rotating component, such as a drive shaft.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to overcome the defects of the technology and provide a high-pressure rotary sealing ring structure.

In order to solve the technical problem, the technical scheme provided by the utility model is a high-pressure rotary sealing ring structure which comprises a ring body sleeved on the peripheral surface of a rotating shaft, wherein sealing teeth are arranged on the inner wall of the ring body close to two ends of the ring body, the sealing teeth consist of high teeth and low teeth which are arranged in a staggered mode, spiral teeth are arranged between the sealing teeth on two sides of the ring body and between the inner walls of the ring body, and a retaining ring is arranged at one end, far away from equipment, of the ring body.

As an improvement, the high teeth and the low teeth are both arranged to be circular ring type structures.

As a refinement, the helical teeth are arranged in an array with the ring body axis as a central axis.

As a refinement, the helical tooth direction of rotation is opposite to the direction of rotation of the axis of rotation.

As the improvement, the high-pressure rotary sealing ring is made of carbon fibers.

Compared with the prior art, the utility model has the advantages that:

the lubricating oil liquid is prevented from leaking to the outside of the case along the axis direction by the high and low sealing teeth arranged at the two ends of the ring body, the rotating direction of the spiral teeth at the middle part of the sealing ring body is opposite to the rotating direction of the rotating shaft, and the spiral teeth apply acting force opposite to the flowing direction of the lubricating oil to the lubricating oil fluid filled between the spiral teeth.

Detailed Description

The structure of a high-pressure rotary seal ring according to the present invention will be described in further detail with reference to the accompanying drawings.

With reference to fig. 1-3, a high-pressure rotary seal ring structure includes a ring body 1 sleeved on the outer peripheral surface of a rotating shaft, sealing teeth 2 are disposed on the inner wall of the ring body 1 near two ends of the ring body, the sealing teeth 2 are composed of high teeth 201 and low teeth 202 which are arranged in a staggered manner, spiral teeth 3 are disposed between the inner walls of the ring body 1 between the sealing teeth 2 on two sides, and a retainer ring 4 is disposed at one end of the ring body 1 far from a device.

As a preferred embodiment of the present embodiment, the high teeth 201 and the low teeth 202 are both configured as a ring-shaped structure.

As a preferred embodiment of the present embodiment, the helical teeth 3 are arranged in an array with the axis of the ring body 1 as a central axis.

As a preferred embodiment of the present embodiment, the direction of rotation of the helical teeth 3 is opposite to the direction of rotation of the rotating shaft.

As a preferred embodiment of this embodiment, the material of the high-pressure rotary seal ring is carbon fiber.

When the utility model is implemented specifically, the inner wall of the ring body 1 is provided with the sealing teeth 2 near the two ends, the sealing teeth 2 are composed of high teeth 201 and low teeth 202 which are arranged in a staggered mode, the spiral teeth 3 are arranged between the sealing teeth 2 at the two sides of the inner wall of the ring body 1, one end, far away from equipment, of the ring body 1 is provided with the retaining ring 4, lubricating oil liquid is prevented from leaking to the outside of a case along the axial direction through the high and low sealing teeth 2 arranged at the two ends of the ring body 1, the rotating direction of the spiral teeth 3 in the middle of the sealing ring body 1 is opposite to the rotating direction of the rotating shaft, and the tooth surface of the spiral teeth 3 applies acting force opposite to the lubricating oil flow direction to the lubricating oil liquid filled between the spiral teeth.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the utility model as defined by the appended claims.
