Description

It offers a self-assembly BL; h1 ::, ;; is a rolling bearing with two concentrically disposed:, ::: groups of rollers or balls.

Multiple radial roller bearings with concentrically arranged groups of balls or rollers that perceive radial forces are known.

The proposed bearing differs from the well-known similar bearings in that it uses thrust bearings that interact with the end surfaces of the middle ring of the radial rolling bearing.

The drawing schematically shows the bearing in the section.

The bearing is the inner ring I, n is mounted on the shaft 2, the middle ring 3, the outer ring 4 rigidly fixed in the housing 5, two concentric groups of rollers 6 and 7 and two thrust bearings consisting of rings 8 and balls 9.

When the shaft 2 rotates, the rollers 6 roll along the outer surface of the inner ring 1 and along the inner surface of the middle ring 3, which is entrained in the rotation, but makes fewer revolutions than the shaft. The rollers 7 roll along the outer surface of the middle ring and along the inner surface of the outer ring 4. The forces acting along the shaft axis are perceived by the thrust bearing rings 8, through which the middle rings 3 of the radial rolling bearing abut their ends through the balls 9.

In connection with this. that the working surfaces of the rings 1. 3 and 4 are executed with (augeric, the subframe is self-stabilizing.

Subject invention

1. Roller bearing with concentrically arranged groups of balls or rollers for 5 bearing with 1 radial reinforcements, characterized in that it is equipped with axial bearings for interlocking axial forces that interact with the end surfaces of the middle ring of the radial rolling bearing.
