Embodiment 1

[0024] Such as Figure 1 to Figure 4 As shown, a reciprocating eccentricity-resistant oil sealing device includes a long-tube stepped sealing sleeve 8, and the sealing sleeve 8 is provided with a rounded groove 12 at the step distribution position; the wall of the sealing sleeve 8 The thickness is 1.5 mm; the sealing sleeve 8 is provided with a sealing lip 11; the bottom of the sealing sleeve 8 is provided with a rigid skeleton 13 in a flanging structure 14, and a sealing rubber body 15 is provided on the outside of the skeleton 13; The sealing lip 11 is set to be wave-shaped; the sealing lip 11 is set to form an interference fit structure with the connecting rod 7; the sealing rubber body 15 outside the skeleton 13 is set to form an interference fit with the casting hole structure.

[0025] The method of using the oil sealing device for complex resistance to eccentricity includes the following steps:

[0026] The first step is to install the shaft 4 into the casting 3, and ...

Embodiment 2

[0032] The same as in the first embodiment, the difference is that the wall thickness of the sealing sleeve is 1 mm, and the sealing lip 11 is set in a zigzag shape.

Embodiment 3

[0034] Same as embodiment 1, the difference is that the wall thickness of the sealing sleeve is 2mm.

[0035] In this way, when working, a reciprocating eccentricity-resistant oil sealing device of the present invention and its use method and application, the casting 2 forms an oil chamber 1, and the oil chamber is filled with gear oil, and the casting 3 forms an oil chamber 6, and there are gears in the oil chamber. Oil, the connecting rod 7 is connected with the shaft 4, and the shaft 4 drives the connecting rod 7 to reciprocate up and down, and there is a 10° swing. There is a large gap between the connecting rod 7 and the hole of the casting 2, and the sealing sleeve 8 needs to be used here for sealing , so as to prevent the oil in the two oil chambers from permeating each other; the gap between the shaft 4 and the casting 2 is sealed by the oil seal 5. When assembling, put the shaft 4 into the casting 3, and then install the sealing sleeve 8 in the seat hole of the casting...

Abstract

The invention belongs to the technical field of sealing members, and in particular relates to a reciprocating eccentricity prevention oil sealing device, and an application method and application thereof. The reciprocating eccentricity prevention oil sealing device comprises a long cylindrical steeped gland cover, wherein the gland cover is provided with a round angle groove at a stepped distribution part; the wall thickness of the gland cover is 1-2 mm; the gland cover is provided with a sealing lip; a rigid skeleton in a flange structure is arranged at the bottom of the gland cover, and a sealed rubber body is arranged outside the skeleton; the sealing lip is waved or saw tooth shaped; the sealing lip is a structure having an interference fit with a connecting rod; and the sealing rubber body outside the skeleton is a structure having an interference fit with a cast hole. According to the invention, the axial reciprocating motion of the gland cover along with the rod can be realized, the gland cover can swing freely along with the rod, requirements for swinging the rod for 10 degrees can be satisfied, the gland cover and the rod cannot generate relative movement; two cavities are isolated by a sealing medium so as to prevent gear oil in the cavity from leaking, thus the sealing effect and the eccentricity prevention performance are better.

Description

technical field [0001] The invention belongs to the technical field of seals, and in particular relates to a reciprocating eccentricity-resistant oil sealing device and its use method and application. Background technique [0002] In some guide rod structures, the two oil chambers communicate with each other, and a transmission rod runs through the two oil chambers in the middle hole. The reciprocating stroke of this rod is generally about 10mm~15mm, and the eccentric swing is generally 10 degrees. The gear oil in the lower oil chamber flows into the lower oil chamber, and the gap around the transmission rod needs to be sealed. For this reason, a sealing device is needed, which can not only meet the reciprocating and eccentric movements of the rod, but also ensure that the gear oil in the upper oil chamber does not leak , so as to meet the needs of the actual situation. Contents of the invention [0003] The invention provides a reciprocating eccentricity-resistant oil se...
