Embodiment Construction

[0031] The assembly method of the non-elastic sealing ring of the present invention and the assembly device for implementing the method will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0032] A method for assembling a non-elastic sealing ring, the steps of which are as follows:

[0033] 1. First, fix the rotating shaft workpiece that needs to be assembled with the sealing ring on the workbench;

[0034] 2. Put a guide cylinder with a smooth outer wall and a small diameter at the upper end and a cylindrical lower end on the rotating shaft, so that the lower port of the guiding cylinder is aligned with the upper rib of the sealing groove on the rotating shaft; the lower port of the guiding cylinder is The outer diameter is consistent with the outer diameter of the upper rib of the sealing groove on the rotating shaft; the so-called basically the same means that the difference in diameter is about 1mm.

[0035] 3. Expand t...

Abstract

The invention discloses a method for assembling an unelastic seal packingring and an assembly device for implementing the method. The assembly method is as follows: fixing work pieces, sheathing a guide cylinder on a rotating shaft, sheathing a seal packingring on the cylindrical guide cylinder, sheathing a cylinder on the guide cylinder, pushing the seal packingring into a seal groove on the rotating shaft, retracting the cylinder, taking down the guide cylinder, clipping the seal packingring by a clip, causing the seal packingring to be reset in a dual rectangular way, and withdrawing the clip, thereby accomplishing the assembly of the seal packingring. The unelastic seal packingring assembly device for implementing the method is characterized by comprising a workbench (1), a work piece clamp seat (11), a guide post (3), a push ring cylinder(4) and the clip(5), and has the advantages of great reduction of tensile failure rate of the unelastic seal packingring, favorable shape restoration of the seal packingring, high assembly efficiency and favorable seal effect.

Description

Technical field: [0001] The invention relates to the installation of sealing rings in the mechanical industry, in particular to a method and an assembly device for installing a sealing ring between two relatively rotating parts, specifically to an assembly method of a non-elastic sealing ring and an assembly for implementing the method device. Background technique: [0002] The elastic sealing ring has the characteristics of free expansion and contraction. After being pulled apart, it is placed on the sealing groove. Depending on the elastic recovery force of the sealing ring itself, the sealing ring is naturally placed in the sealing groove, which is very convenient for assembly; the elastic sealing ring is in a static object. Its sealing effect is very good, but when used in dynamic objects, its free expansion and contraction characteristics become a fatal weakness. This is because the elastic sealing ring is between two relatively rotating parts, and the rotating parts ar...
