Embodiment 1

[0024] Such as Figure 1 to Figure 4 As shown, an oil sealing device for reciprocating eccentricity resistance includes a sealing sleeve 8 set as a long cylindrical stepped shape, and the sealing sleeve 8 is provided with a rounded groove 12 at a position where the steps are distributed; the wall of the sealing sleeve 8 The thickness is 1.5mm; the sealing sleeve 8 is provided with a sealing lip 11; the bottom of the sealing sleeve 8 is provided with a rigid frame 13 in a flanging structure 14, and a sealing rubber body 15 is provided on the outside of the frame 13; The sealing lip 11 is set to be wavy; the sealing lip 11 is set to form an interference fit with the connecting rod 7; the sealing rubber body 15 outside the frame 13 is set to form an interference fit with the casting hole structure.

[0025] The method of using the oil sealing device for re-resistant eccentricity includes the following steps:

[0026] In the first step, install the shaft 4 into the second casting 3, ...

Embodiment 2

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

Embodiment 3

[0034] The same as the first embodiment, the difference is that the wall thickness of the sealing sleeve is 2 mm.

[0035] In this way, when working, the method for using the reciprocating eccentricity-resistant oil sealing device of the present invention is that the first casting 2 forms an oil cavity 1, which is filled with gear oil, and the second casting 3 forms an oil cavity 6, which has Gear oil, connecting rod 7 is connected with shaft 4. Shaft 4 drives connecting rod 7 to reciprocate up and down, and has a 10° swing. There is a large gap between connecting rod 7 and the hole of first casting 2, and sealing sleeve is needed here. 8 is sealed to prevent the oil in the two oil chambers from permeating each other; the gap between the shaft 4 and the first casting 2 is sealed by the oil seal 5. When assembling, the shaft 4 is installed in the second casting 3, and then the sealing sleeve 8 is installed in the second casting 3. In the seat hole of a casting 2, the connecting ro...

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 method of using an oil sealing device for reciprocating eccentricity resistance. Background technique [0002] In some guide rod structures, the two oil cavities are connected, and a transmission rod runs through the two oil cavities in the middle hole. The reciprocating stroke of this rod is generally about 10mm to 15mm, and the eccentric swing is generally 10 degrees. In order to prevent oiling The gear oil in the cavity flows into the lower oil cavity, 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 movement of the rod, but also ensure that the gear oil in the upper oil cavity does not leak , So as to meet the needs of the actual situation. Summary of the invention [0003] The invention provides a method for using an oil sealing device for reciprocating ecc...
