Abstract
The utility model discloses a single-groove joint bearing which comprises a shell and a joint ball arranged in the shell, wherein a ball groove is dug on the outer surface of the joint ball, a plurality of steel balls are arranged between the shell and the joint ball through the ball groove, oil storage grooves are dug on the outer surface of the joint ball and on two sides of the ball groove, a Teflon wear-resistant sheet is fixed on the inner wall of the shell, a plurality of bulges are arranged on one surface of the Teflon wear-resistant sheet close to the joint ball, and a steel sheet with a plurality of holes capable of being matched with the bulges is arranged on the surface of the Teflon wear-resistant sheet in a matching manner. The single-groove joint bearing is ingenious in structure, the oil storage grooves are formed in the two sides of the ball groove provided with the steel ball, oil can be stored in the oil storage grooves, the defects of insufficient lubrication and short heating life are overcome, and the Teflon wear-resistant sheet and the steel sheet are arranged on the inner wall of the shell, so that the lubrication and the heat dissipation are better.
Description
Technical Field
The utility model belongs to the field of mechanical parts, and particularly relates to a single-groove joint bearing.
Background
In the existing single-groove knuckle bearing, the end of a single-groove knuckle rod is easy to lubricate at a high speed, so that the heating life is short, and a lubricating sheet is easy to damage, so that the service life of the bearing is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a single-groove joint bearing.
The utility model is realized by the following technical scheme:
single ditch joint bearing, including casing and the joint ball of setting in the casing, dig on the surface of joint ball and be equipped with a ball ditch, pass through between casing and the joint ball the ball ditch and be equipped with a plurality of steel ball, on the surface of joint ball, the both sides of ball ditch, still all dig and be equipped with the oil storage tank, on the shells inner wall, still be fixed with special fluorine dragon wear pad, special fluorine dragon wear pad is equipped with a plurality of arch on being close to the one side of joint ball, the laminating is in on the special fluorine dragon wear pad and with special fluorine dragon wear pad cooperation ground, be equipped with above-mentioned distribute can with protruding a plurality of downthehole steel sheet of matched with.
Preferably, an extension bar is further connected to the housing.
Preferably, the teflon wear-resistant sheet is embedded in the inner wall of the shell.
The utility model has the beneficial effects that:
the single-groove joint bearing provided by the utility model has the advantages that the structure is ingenious, the oil storage grooves are formed in the two sides of the ball groove provided with the steel ball, grease can be stored in the oil storage grooves, the defects that the traditional single-groove joint rod end is not lubricated in place and short in heating life when rotating at a high speed are overcome, and the lubricating and heat dissipating effects between the joint ball and the shell are better because the Teflon wear-resisting sheet with ultrahigh wear resistance and the steel sheet with excellent heat dissipating and lubricating properties are arranged on the inner wall of the shell and are ingeniously matched with the Teflon wear-resisting sheet, so that the service life of the bearing can be greatly prolonged, the practicability is strong, and the single-groove joint bearing is worthy of popularization.
