Abstract
The utility model relates to a single-ball groove type oscillating bearing, which comprises an oscillating ball (1) and a casing (2). The oscillating ball is a ball body with a hole in the center, a through hole matched with the oscillating ball is arranged in the center of the casing, and the oscillating ball is embedded in the casing through the through hole. The single-ball groove type oscillating bearing is characterized in that an annular groove (3) is arranged on the inner wall of the casing, an annular ball groove (4) is arranged on the outer circle face of the oscillating ball, a plurality of waist-drum-shaped rollers (3) are arranged between the ball groove and the groove of the casing, and the casing adopts AF316 stainless steel materials. The single-ball groove type oscillating bearing utilizes rolling friction of the roller to replace traditional sliding friction, greatly reduces friction force of the oscillating bearing in work and ensures safe reliability of the whole oscillating bearing.
Description
Technical field
The utility model relates to a kind of joint shaft bearing, especially relates to a kind of single gutter type joint shaft bearing.
Background technique
At present, joint shaft bearing is used in clocklike banking motion, oscillating motion and rotatablely moves, and is widely used in fields such as robot, automobile and aircraft.Yet conventional joint shaft bearing directly is embedded at joint ball in the housing, and the liner that between joint ball and housing, adds lubricate is to reduce friction.The patent No. is that the Chinese utility model patent of CN201020212073.4 just discloses a kind of Reinforced Nylon liner that is mixed with Te Fulong that between joint ball and housing, adds; This joint shaft bearing can only be applied in rotating speed with regard to low occasion; Reach 1500 aggravations of friction when changeing above at rotating speed; Wearing and tearing will appear in the working surface of joint shaft bearing, even come off and cause the bearing can't proper functioning.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, the single gutter type joint shaft bearing that provide a kind of and can run up, reliability is high, wear resistance is good.
The purpose of the utility model is achieved in that a kind of single gutter type joint shaft bearing; It comprises joint ball and housing, and said joint ball is the spheroid of center drilling, and said housing center has the through hole that is complementary with joint ball; Said joint ball is embedded in the housing through this through hole; Have an annular gutter on the periphery of said joint ball, between the inwall of said gutter and housing, be provided with some waist drum type rollers, said housing adopts the AF316 stainless steel material.
Between said housing and joint ball, be provided with dust ring, said dust ring is positioned at the both sides of waist drum type roller.
On the periphery of said housing, a connection piece is set, said link connects a housing and an extension bar, and a fuel filler neck is set on said link, and said fuel filler neck is connected with the gap of housing and joint ball.
Compared with prior art, the beneficial effect of the utility model is:
The utility model list gutter type joint shaft bearing utilizes the rolling friction of ball to substitute traditional sliding friction; Greatly reduce the frictional force of joint shaft bearing when work; Make joint shaft bearing under the running up more than 1500 rev/mins, to work, guaranteed the safety reliability of whole joint shaft bearing.
