Problems solved by technology

[0002] In the prior art, the thrust bearings are all single-roller layer bearings or bidirectional single-roller layer bearings, and the fundamental feature of the bidirectional single-roller layer bearings is that the middle ferrule is a fixed common ferrule that cannot participate in rotation. The inner diameter of the common ferrule is smaller than that of the rotary ferrules at both ends, and it is used to fix on the shaft. It is difficult for a single roller layer thrust bearing to reduce frictional resistance and wear, and it can only bear axial pressure and small radial pressure

Embodiment 1

[0018] Such as figure 1 , 2 The shown intermediate layer ring for thrust bearing, the intermediate layer ring for thrust bearing, the inner track groove 2 and the outer track groove 3 opened on both ends of the middle layer ring body 1, the axial section of the middle layer ring body 1 is The variable diameter structure, the rolling elements assembled in the inner track groove 2 and the outer track groove 3 generate a forward tensile force on the middle ring in the axial direction, the radial projections of the inner track groove and the outer track groove intersect or intersect, and the inner track groove and the outer track groove The outer track groove is used as angular contact track groove, deep groove ball roller track groove, or cylindrical roller track groove, spherical roller track groove, tapered roller track groove or toroidal roller track groove. Figure 5 As shown, the rolling elements 4 cooperate with the inner track groove 2 and the outer track groove 3 respect...

Embodiment 2

[0020] Such as image 3 , 4 The basic structure of the middle layer ferrule for the thrust bearing shown is the same as that of the embodiment. The inner track groove 2 of the middle layer ferrule is a spherical track groove, and the outer track groove 3 is an angular contact track groove and a deep groove ball roller track groove. , or cylindrical roller track grooves, spherical roller track grooves, tapered roller track grooves or toroidal roller track grooves.

Abstract

The invention relates to a bearing, and especially relates to an interlayer ferrule of a multi-ferrule bearing. An interlayer ferrule for a thrust bearing is provided. An inner track groove and an outer track groove are disposed on two end surfaces of an interlayer ferrule main body; the axial section of the interlayer ferrule main body is a structure with variable diameters; rolling elements assembled in the inner track groove and the outer track groove can generate pathwise pulling force to the interlayer ferrule in the axial direction. The invention adopts an interlayer ferrule with variable diameters; the track grooves disposed at the inner and outer circumferences of the interlayer ferrule are staggered from the axle center by a diameter difference, which allows the radial projection of the inner track groove and the outer track groove of the ferrule to intersect or be staggered; the vertical shearing and bending pressure due to the radial point contact between the inner and outer rollers and the interlayer ferrule can be changed into pathwise pulling force to the interlayer ferrule in the radial direction; the mechanical structure change can greatly increase the bearing capacity of the interlayer ferrule; the stability of the bearing interlayer during high-speed rotation is effectively controlled.

Description

technical field [0001] The present invention relates to bearings, in particular to intermediate rings of bearings. Background technique [0002] In the prior art, the thrust bearings are all single-roller layer bearings or bidirectional single-roller layer bearings, and the fundamental feature of the bidirectional single-roller layer bearings is that the middle ferrule is a fixed common ferrule that cannot participate in rotation. The inner diameter of the common ferrule is smaller than that of the rotary ferrules at both ends, and it is used to fix on the shaft. It is difficult for single roller layer thrust bearings to reduce frictional resistance and wear, and can only bear axial pressure and small radial pressure. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides an intermediate layer ring for thrust bearings, which adopts a variable diameter structure to change the mechanical structure of the intermediate l...
