Abstract

The technical solution relates to mechanical engineering, and more specifically to the designs of rolling bearings operating under conditions of high speed and requiring the use of liquid oils or sprayed oils as a lubricant.

The essence of the technical solution lies in the fact that the channels for supplying lubricant are made in the outer ring of the bearing and are located at an acute angle to the axis of symmetry of the bearing. The angle of inclination of the channel axis can be made equal to 25-40 °, and the number of channels in the outer ring of the bearing is even, at least two, and they are located symmetrically around the circumference. 3 pf, 3 ill.

The technical solution relates to mechanical engineering, and more specifically to the designs of rolling bearings, bearings, their bearings for shafts operating under conditions of high speed and requiring the use of liquid oils or sprayed oils as a lubricant.

Known designs of ball and roller rolling bearings, in the outer ring of which are made radial channels for supplying lubricant to the surface of the raceway of the ring (Catalog "Rolling bearings. Free rolling bodies. Products of bearing factories in Russia and the CIS, VNIPPP, Moscow, 1999, pp. .445, fig. 40, p. 470, fig. 4050, 4052, 4170). The disadvantage of this design of the rolling bearing is the location of the radial channels in the plane of symmetry of the bearing strictly perpendicular to the axis of the shaft. This can cause vibrations and lead to premature bearing failure. In addition, in such a bearing, the separator is loaded unilaterally with a stream of lubricant, which leads to increased wear.

The technical result of the proposed utility model is a new bearing design, which has increased performance and reliability due to improved working conditions of the rolling elements and the cage and significantly lower losses during rotation.

This problem is solved in that the rolling bearing containing the outer and inner rings and the rolling bodies located between them, channels for supplying lubricant are made on the outer ring.

At the same time, an annular groove is made on the outer side of the outer ring, and the channels are located at an angle to the axis of symmetry of the bearing. This angle can be made in the range of 25-40 °, and their number is chosen even, at least two, and they are located symmetrically around the circumference.

Sush, nost of the claimed utility model is illustrated in the drawing, which shows:

FIG. 1 - section in the plane of ingrowth;

figure 2 is a cross section along the axis of symmetry of the combined on the same figure ball 1 and roller 2 rolling bearings.

Rolling bearings 1 and 2 contain an outer 3 and an inner 4 ring with rolling bodies between them in the form of balls 5 and in the form of rollers 6 with a cage 1. In the outer rings 3 of the bearings 1 and 2, a groove 8 is made on the outside and channels 9 are drilled for nodvoda lubricant to the rolling elements 5 and 6. Channels 9 are inclined at an angle a - 25-40 to the vertical axis, and their number is chosen even, for example, at least two, and they are symmetrically opposed to each other.

This design solution of the rolling bearing creates favorable conditions for the operation of the rolling elements and the cage, increases the reliability and durability of the bearing of the proposed design. Applicant: by proxy (-. G.A. Glushkov
