Self-lubricating plain radial bearing and manufacturing method thereof

Abstract

The invention relates to a bearing, in particular to a self-lubricating plain radial bearing used for a V-shaped thrust rod straight ball seat of a truck and a manufacturing method thereof, comprisingan inner ring and an outer ring as well as a self-lubricating material pad, wherein the external spherical surface of the inner ring is mutually matched with the internal spherical surface of the outer ring for rotation, the self-lubricating material pad is clung on the internal spherical surface of the outer ring, the internal spherical surface of the self-lubricating material pad is mutually matched with the external spherical surface of the inner ring for rotation, the inner ring is a solid ball body, wherein two extension rods extend out from two ends thereof, and installation holes are arranged on the two extension rods; and the outer ring has an integral structure. The invention adopts an assembly method that the outer ring is extruded and assembled in the inner ring, the internal spherical lining of the outer ring is provided with a layer of the self-lubricating material pad, and the self-lubricating material pad is firmly clung to the internal spherical surface of the outer ring, thus forming a steel and self-lubricating material friction pair, reducing abrasion of the bearing during work, and leading the bearing to have maintenance-free function.

Description

technical field [0001] The invention relates to a bearing, in particular to a self-lubricating radial joint bearing for a straight ball seat of a V-shaped thrust rod of a truck and a manufacturing method thereof. Background technique [0002] The straight ball seat on the V-shaped thrust rod of the truck in the prior art usually adopts the structure of a layer of rubber body vulcanized on the surface of the spindle-shaped pin shaft, and the two ends of the rubber body are respectively fixed with metal end caps. Although the impact resistance is good, the deflection during work can only be realized by rubber deformation, and the deformation is limited. Therefore, the swing angle of the pin shaft can only slightly swing along with the deformation of the rubber. If the swing angle is small, the rubber is easy to fail under the impact and deformation of the vehicle frame, and the service life is very low. Contents of the invention [0003] The main purpose of the present inve...

[0002] The straight ball seat on the V-shaped thrust rod of the truck in the prior art usually adopts the structure of a layer of rubber body vulcanized on the surface of the spindle-shaped pin shaft, and the two ends of the rubber body are respectively fixed with metal end caps. Although the impact resistance is good, the deflection during work can only be realized by rubber deformation, and the deformation is limited

Therefore, the swing angle of the pin shaft can only be slightly deflected according to the deformation of the rubber. The swing angle is small, and the rubber is easy to fail under the impact and deformation of the frame, and the service life is very low.
