Description

 . . . . FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular, to carved stone. A cage bearing separator is known, consisting of separating frontal rollers with guides 6. However, this separator does not provide for forced self-lubrication of bearings in the absence of sources of lubricant material, which reduces the service life of bearings. The purpose of the invention is to increase the bearing service life. The goal is achieved by the fact that the guide shoulders of the separating roller are made with different outer diameters, and the axis of its rotation is angled to the axis of the bearing. The outer diameters of the shoulders of the sleeves of a separate roller are related by the ratio B. dsh w- where 0B is the outer diameter of the larger guide flange; 0A - the outer diameter of the smaller outer collar / d - the diameter of the ball; D is the outer diameter of the hearth; d is the inner diameter of the bearing; , k - form factor. The angle ai between the axes of the separation of the rollers and the axis of the bearing is determined by the relation D – d oc - arcig- where L is the length of the separating roller. In addition, the center of mass of the separating roller is located outside its axis of rotation. FIG. 1 shows a bearing separation roller, a slit; in fig ;. 2 separating rollers assembled; in fig. 3, 4 - possible embodiments of the separation rollers. The separating rollers 1 with the axis of rotation 00., separating, the balls 2, have guide beads 3 and 4 in contact with the rolling surface 5 of the outer ring and the rolling surface 6 inside; In this case, the diameters of the guide shoulders 3 and 4 are related by the ratio. ; . Fb 3sh -one

where fl) B is the outer diameter of the larger

bead guide / FA - the outer diameter of the smaller

guide collar,. dm is the diameter of the ball; b is the outer diameter of the bearing; d is the inner diameter of the bearing, ka;

K - form factor. The shape factor can be from 0.15-0 / 25. The rotation axis 00 of the separating roller forms an angle cL with the axle of the bearing 02.0, which is determined by the ratio

o6 - arctg.

where L is the length of the separation roller.

The rolling bearing cage operates as follows.

When the outer surface 5 rolls rotate relative to the inner surface of the rolling body b, the rolling body 2 and the separating rollers 1 separating them also come into rotation. At the same time, the presence of angle ai between axes 00. and axes 020-5 of non-zero rolling surfaces causes an axial component force that presses the separating rollers 1 against rolling bodies 2, thereby ensuring the application of a lubricant rolling The guiding actions of the said axial component force depend on which surface of the contact the guide pins 3 and 4 of the separating rollers 1. The presence of the displacement of the centers of mass and the axes of rotation 00 of the separating rollers causes the alternating contact of the guide pads 3 and 4 with rolling surfaces 5 and 6 i. This ensures the self-lubrication of the rolling bearing and increases the service life of the latter.
