Example Embodiment

[0032] Example 1:

[0033] like figure 1 2, a mating plastic rod terminal joint bearing, including a rod end body 1, and an outer ring body 2 is provided, and an inner ring body is provided in the outer ring body 2; wherein The outer ring body 2 includes a first circle port 21 and a second circle port 22 along the inner loop body 3, and the inside of the first circle port 21 is provided with a fitting groove 5; wherein the loading groove 5 is provided. The seal 4 is provided in the inner fastener. The loading groove 5 is used to smoothly load the outer ring body 2, after being loaded in the inner lone body 3, the sealing member 4 is fastened to the connecting fitting groove 5, the seal 4 can enclose the first circle 21 In order to avoid dust such as dust, the outer ring body 2 and the inner ring body 3, while the internal ring body 3 is limited to the front and rear positions of the outer ring body 2, and the inner ring body 3 and the outer ring body 2 are eliminated The gap ensur...

Abstract

The invention relates to an assembly type plastic rod end knuckle bearing. The assembly type plastic rod end knuckle bearing comprises a rod end body, an outer ring body is arranged on the rod end body, and an inner ring body is arranged in the outer ring body, wherein the outer ring body comprises a first ring opening and a second ring opening in the installing direction of the inner ring body, and an assembling groove is formed in the inner side of the first ring opening; and a sealing piece is arranged in the assembling groove in a buckled mode. The inner ring body is limited in a wrapped mode by the first assembling surface between the first ring opening and the second ring opening in the axial direction, it is guaranteed that the inner ring body cannot be disengaged from the ring openings in the two sides of the outer ring body in the working process, and the structure is stable after assembling, and the phenomenon that the inner ring body is clamped or too loose in the running process is avoided. The inner ring body and the outer ring body are subjected to injection molding in a separated injection molding mode, and the sealing piece is used for controlling a gap after the inner ring body is installed in the outer ring body, so that the inner ring body and the outer ring body can be attached without a gap and can rotate smoothly, and the running smoothness of the plastic rod end knuckle bearing is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of joint bearings, in particular to an assembled plastic rod end joint bearing and a manufacturing method thereof. Background technique [0002] Joint bearing is a kind of spherical sliding bearing, its sliding contact surface is an inner spherical surface and an outer spherical surface, which can rotate and swing at any angle during motion. [0003] Joint bearings are mainly composed of an inner ring body with an outer spherical surface and an outer ring body with an inner spherical surface. Joint bearings are generally used for low-speed swing motion (that is, angular motion). Since the sliding surface is spherical, it can also perform tilting motion (that is, self-aligning motion) within a certain angle range. When the temperature is large, it can still work normally. [0004] Traditional joint bearings are made of metal materials, and the inner ball is fixed in the outer shell by using the heat or cold...
