Assembly method for swivel joint of all-terrain vehicle and swivel joint

Abstract

The invention discloses an assembly method for a swivel joint of an all-terrain vehicle and the swivel joint. The assembly method comprises the steps of installation of a fastening copper gasket A, guiding and sliding installation of a sealing ring, hooping of the sealing ring, assembling of a core and a shell body, in-place assembling and rotating of the core and the shell body, installation of a plug, installation of a rear end cover and installation of the joint. The sealing ring pulls an electric wire along the outer circle of the core, and the sealing ring is sleeved with a O-shaped ring in a groove of the core in a sliding mode under the guide of the electric wire, so that the problem that the sealing ring is difficult to assemble in the prior art is solved, the production efficiency of the swivel joint is improved, and the sealing ring is sleeved with the O-shaped ring in the groove of the core in a sliding mode under the guide of the electric wire and then is held tightly by a hoop, so that it is guaranteed that the deformation of the sealing ring after local deformation is uniformly diffused to each part of the sealing ring and then uniformly contracts to hold tightly the O-shaped ring, and the sealing ring can make uniform contact with the shell body after being uniformly deformed and contracted, and the sealing performance of the sealing ring in use is improved.

Description

technical field [0001] The invention relates to an assembly method of a rotary joint of an all-terrain vehicle and the rotary joint, belonging to the technical field of the rotary joint. Background technique [0002] For an all-terrain vehicle suitable for all-terrain, water, all-weather and amphibious functions, due to the complex and compact structure of the rotary joint, the sealing ring in the oil seal needs to be placed on the outer circle of the core, using the existing assembly It is difficult to assemble the method, which reduces the production efficiency of the rotary joint; [0003] In the Chinese Patent Publication No. CN103646604B, the central rotary joint installation guidance device and installation method, although the central rotary joint installation guidance device switches from the plane state to the three-dimensional state, can realize the guidance of the central rotary joint, but only for the central rotary joint The guidance of the oil port after assem...

Problems solved by technology

[0002] For an all-terrain vehicle suitable for all-terrain, water, all-weather and amphibious functions, due to the complex and compact structure of the rotary joint, the sealing ring in the oil seal needs to be placed on the outer circle of the core, using the existing assembly It is difficult to assemble the method, which reduces the production efficiency of the rotary joint;

[0003] In the Chinese Patent Publication No. CN103646604B, the central rotary joint installation guidance device and installation method, although the central rotary joint installation guidance device switches from the plane state to the three-dimensional state, can realize the guidance of the central rotary joint, but only for the central rotary joint The guidance of the oil port after assembly between the core and the shell of the joint still does not solve the problem of the difficulty that the sealing ring fits on the outer circle of the core
