Embodiment

[0035] Example: such as Figure 3 to Figure 5 Shown is a self-locking and anti-loosening sealing method for sealing bolts, which is to set the bolts 4 into separate parts, and install a gasket 5 between the split bolts 4, and the gasket is located between the external thread 412 of the bolt and the cone of the bolt. The positions between the type tops 413 are achieved by screwing the split bolts into the liquid injection hole 1 to achieve a self-locking and anti-loosening seal. Through structural design, this embodiment cleverly adds gaskets on the basis of ensuring that the original sealing effect can be achieved, thereby preventing the occurrence of bolt looseness and ensuring good sealing performance during daily work, thereby eliminating the need for safety. Hidden danger.

[0036] The split bolt 4 includes a tail bolt body 414 and a top bolt body 415, the gasket 5 is set between the tail bolt body 414 and the top bolt body 415, and the nut part 411 is arranged on one end...

Abstract

The invention discloses a self-locking and anti-loosening sealing method of a sealing bolt and a self-locking and anti-loosening sealing bolt, wherein the self-locking and anti-loosening sealing method of the sealing bolt is that the bolts are arranged in separate parts, and the split-type bolts are additionally installed Gasket, the gasket is located between the external thread of the bolt and the conical top of the bolt, and the split bolt is screwed into the liquid injection hole, so as to realize the self-locking and anti-loosening seal. Through structural design, the present invention cleverly adds gaskets on the basis of ensuring that the original sealing effect can be realized, thereby preventing the occurrence of bolt looseness, ensuring good sealing performance in the daily work process, and eliminating potential safety hazards .

Description

technical field [0001] The invention relates to a sealing bolt and a working method, in particular to a self-locking and anti-loosening sealing method of the sealing bolt and a self-locking and anti-loosening sealing bolt. Background technique [0002] According to the dynamic requirements, when the pivoting arm node is running in a straight line at high speed (high frequency vibration), it provides a large radial stiffness to ensure the running stability and increase the critical speed; when it passes the curve (low frequency and large amplitude), it provides a small stiffness performance Guaranteed over-curve performance and reduced wear; it is difficult for ordinary joints to achieve the above characteristics, especially for old lines, where wheel rails and lines wear a lot, and the maintenance cost is high. Therefore, it is necessary to use a new product that has the above characteristics at the same time—liquid rubber composite joints. [0003] The working principle of ...
