Description

The invention relates to mechanical engineering, namely to rolling bearings, in particular to radial roller and ball, angular contact roller and ball, persistent ball bearings.

Known full complement rolling bearings containing rings with raceways, rolling elements in the form of balls. In the absence of separators for the separation of rolling elements, the bearings are equipped with a large number of rolling elements and, accordingly, have a greater load-carrying capacity than rolling bearings equipped with cages. These bearings are used for heavy duty operation of mechanisms (Chermensky O.N., Fedotov N.N. Rolling bearings: directory / O.N. Chermensky, N.N. Fedotov. - M.: Mechanical Engineering, 2003. - S. 91).

The disadvantages of full complement bearings are low limit rotational speeds, increased friction moments.

Closest to the proposed invention in technical essence (prototype) is a rolling bearing, containing rings with raceways, rolling elements, separators, at least one, with cells to accommodate the rolling elements. Two or more rolling bodies are placed in one cell. Rolling bodies are made in the form of balls (Chermensky O.N., Fedotov N.N. Rolling bearings: a directory / O.N. Chermensky, N.N. Fedotov. - M .: Mechanical Engineering, 2003. - P.76) .

This bearing is characterized by insufficient load capacity, especially for heavy duty.

The present invention solves the problem of increasing the bearing capacity of a rolling bearing.

To solve the problem, in a rolling bearing containing rings with raceways, separators, at least one, with cells for accommodating rolling bodies, according to the invention, two or more rolling bodies are placed in one cell.

An increase in the load bearing capacity of a rolling bearing is due to a decrease in the number of cells and, correspondingly, the number of jumpers between the cells, which makes it possible to increase the number of rolling bodies placed in the bearing, and thereby increase its load capacity at a high limit speed and a low friction moment.

The drawing shows examples of the design of the invention, namely, figure 1 shows a radial roller bearing, front view; figure 2 - angular contact ball bearing, front view; figure 3 - angular contact roller conical roller bearing, front view; figure 4 - thrust ball bearing, front view; figure 5 is the same as in figure 5, a top view; figure 6 - radial roller bearing, front view; in Fig.7 is the same as in Fig.6, side view.

The radial roller bearing contains an outer ring 1 and an inner ring 2 with raceways, rolling elements made in the form of rollers 3. To accommodate the rolling elements, the bearing is equipped with a cage 4 with cells formed by jumpers. In one cell of the separator 4 placed two rollers 3 (figure 1).

The angular contact ball bearing contains an outer ring 5 and an inner ring 6 with raceways, rolling elements made in the form of balls 7. To accommodate the rolling elements, the bearing is equipped with a separator 8 with cells formed by jumpers. In one cell of the separator 8 placed two balls 7 (figure 2).

The angular contact roller conical roller bearing contains an outer ring 9 and an inner ring 10 with conical raceways, rolling elements made in the form of conical rollers 11. To accommodate the rolling elements, the bearing is equipped with a cage 12. Two rollers 11 are placed in one cell of the cage 12 (Fig. .3).

The thrust ball bearing contains an upper ring 13 and a lower ring 14 with raceways, rolling elements made in the form of balls 7. To separate the rolling elements, the bearing is equipped with a cage 15. Two balls 7 are placed in one cage of the cage 15 (Fig. 4. 5) .

The radial ball bearing contains an upper ring 16 and a lower ring 17 with raceways, rolling elements made in the form of balls 7. To separate the rolling elements, the bearing is equipped with a cage 18. Two balls 7 are placed in one cage of the cage 18 (6, 7) .

In the proposed rolling bearing, several separators can be installed, at least one, and two or more rolling bodies can be placed in one cell.

Radial roller bearing operates as follows.

A radial roller bearing mounted in a node, device, machine provides the perception of loads and transmission of rotation. During the rotation of the rings 1 and 2 of the bearing of the rolling element, made in the form of rollers 3, also rotate, providing the necessary relative position of the bearing rings.

Angular contact ball bearing operates as follows.

An angular contact ball bearing mounted in a node, device, machine, provides the perception of loads and transmission of rotation. During the rotation of the rings 5 and 6 of the bearing, the rolling elements made in the form of balls 7 also rotate, providing the necessary relative position of the bearing rings.

Angular contact roller tapered roller bearing works as follows.

The angular contact roller conic roller bearing installed in the unit, device, machine provides the perception of loads and transmission of rotation. During the rotation of the rings 9 and 10 of the bearing of the rolling element, made in the form of rollers 11, also rotate, providing the necessary relative position of the bearing rings.

Thrust ball bearing works as follows.

A thrust ball bearing mounted in a node, device, machine, provides the perception of loads and transmission of rotation. During the rotation of the rings 13 and 14 of the bearing of the rolling element, made in the form of balls 7, also rotate, providing the necessary relative position of the bearing rings.

Radial ball bearing works as follows.

A radial ball bearing mounted in a node, device, machine, provides the perception of loads and transmission of rotation. During the rotation of the rings 17 and 18 of the bearing of the rolling element, made in the form of balls 7, also rotate, providing the necessary relative position of the bearing rings.

Thus, the implementation of the separator with the possibility of placing two or more rolling elements in one cell of the separator, which provides an increase in the total number of rolling elements in the rolling bearing, allows to increase the load bearing capacity of the rolling bearing at a high ultimate speed of the bearing and low friction.
