Abstract
The utility model relates to a bearing, particularly to a roller joint bearing which is composed of an outer ring and an inner ring, wherein the inner side of the outer ring forms a concave spherical surface, the outer side of the inner ring forms a convex spherical surface, and the radians of the two spherical surfaces are consistent; an arc-shaped roller path is arranged on the convex spherical surface along the inner ring, and a plurality of spherical-surface roller are arranged on the arc-shaped roller path. Holding frames are arranged among the spherical-surface rollers. Both sides of the joint bearing are respectively provided with a dust cap; an oil injecting device is arranged on the outer ring. The joint bearing manufactured according to the method is skillfully provided with the spherical-surface rollers between the inner ring and the outer ring of the spherical-surface bearing, the arc surface sliding friction is changed into rolling friction, and the friction coefficient is reduced to 0.0015 from 0.2; the utility model not only keeps the characteristic that the existing joint bearing can wobble in three dimensional space, but also meets the requirement of rotating in one plane at a high speed, and the service life of the joint bearing is greatly extended.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of roller knuckle bearing.
Background technique
At a kind of joint shaft bearings of multi-field frequent use such as textile manufacturing machine, brush-making machine tool, automobile makings, it can bear very big radial load simultaneously in rotation for a long time, and running shaft relatively shaft axis do swing or tilt.Because this joint shaft bearing is bearing multiple direction loading movement, so structure is more special, as shown in Figure 1, present this bearing is made up of the outer ring 1 that is concave spherical surface, an inboard and the inner ring 2 of a hollow ball, at the centre of outer ring and inner ring copper band commonly used or self lubricating material as anti-attrition layer.Inner ring is done circumference and is rotatablely moved during work, rotation simultaneously relatively shaft axis do swing, this joint shaft bearing is simple sliding friction when working, friction factor is 0.2, because friction factor is big, can only bear 100-300 rev/min rotating speed, friction aggravation when rotating speed is high, bearing working face wearing and tearing, spot corrosion often occur and the damage phenomenon such as peels off and cause bearing not work.This bearing can not adapt to present advanced person's high speed machine transmission industry.
Summary of the invention
In order to address the above problem, it is little that the purpose of this utility model provides a kind of friction factor, adapts to the rotating speed height, the roller knuckle bearing that the life-span is long.
The utility model is mainly solved by following technical proposals: a kind of roller knuckle bearing, form by outer ring and inner ring, the inboard of outer ring is the spill sphere, the outside of inner ring is convex spherical and two sphere radians are consistent, convex spherical along inner ring is provided with arcuate groove, be provided with some spherical rollers on arcuate groove, the radius of curvature of arcuate groove is complementary with the radius of curvature that is arranged in the spherical roller on the arcuate groove.
Described spherical roller is dolioform; Be provided with retainer between spherical roller and the spherical roller; Retainer is shaped as a plurality of continuous S-shaped, two spherical rollers of S shape socket.
The outer ring of bearing, inner ring all adopt the GCr15 steel to make, and through quenching, tempering heat treatment; Respectively be provided with a dust cover in the both sides of joint shaft bearing; On the outer ring, be provided with oil gun.
Produced according to the method described above joint shaft bearing, owing between the inside and outside circle of spherical bearing, be provided with spherical roller dexterously, the cambered surface sliding friction has been become rolling friction, make friction factor reduce to 0.0015 from 0.2, not only kept the existing joint shaft bearing can be in the characteristics of three dimensional space swing, and satisfied the needs of high speed rotating in a plane, and improved the working life of joint shaft bearing greatly.

Embodiment
Below by embodiment, and 2-3 in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of roller knuckle bearing, to form by outer ring 1 and inner ring 2, the inboard of outer ring 1 is the spill sphere, and the outside of inner ring 2 is convex spherical and two sphere radians are consistent.Outer ring 1, inner ring 2 all adopt the manufacturing of GCr15 Bearing Steel, and Bearing Steel improves bearing hardness, intensity after quenching, tempering, strengthen wear resistance.Convex spherical along inner ring 2 is provided with arcuate groove 4, is provided with some spherical rollers 3 on arcuate groove 4, and spherical roller 3 is dolioform, and the size of spherical roller 3 should be complementary with arcuate groove 4, inner ring 2, outer ring 1.Be provided with retainer 5 between spherical roller 3 and the spherical roller 3, retainer 5 is shaped as a plurality of continuous S-shaped, two spherical rollers 3 of S shape socket.The both sides of joint shaft bearing respectively are provided with a dust cover 6, keep the bearing cleaning inside, are provided with oil gun 7 on outer ring 2, have effectively reduced spherical roller 3 and the arcuate groove 4 of inner ring 2, the friction of outer ring 1.
According to different purposes, outer ring 1 one ends of joint shaft bearing can be made rod, the other end of bar is provided with screw thread or other linkage structures, and this moment, the joint shaft bearing with bar can be widely used in textile manufacturing machine, brush-making machine tool, automobile making or the like.
