Description

. one

The invention relates to mechanical engineering, in particular to rolling bearings.

The purpose of the invention is to increase durability and reliability.

Figure 1 shows a schematic representation of a pinged bearing with a floating stop interacting with a liquid working medium; figure 2 - the same, with a floating 1M stop, interacting with cup springs; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 2.

The rolling bearing thrust contains the lower 1 and upper 2 rings, tapered rollers 3, a separator 4 in which cylindrical holes 5 are installed with floating supports 6 installed in them, a set of balls 7 with a separator, rolling tracks 8 that are turned on facing each other face, surfaces of tapered rollers 3 and lugs 6. The rolling bearing can be provided with a bandage 9 that surrounds the outer cylindrical surface of the separator 4, while the cylindrical holes 5 are interconnected by channels 10 and filled with a center oh ioti provided with disk springs 11, interacting with abutments 6.

The rolling bearing thrust according to the first embodiment operates as follows.

475922

When the bearing is loaded axially and rotating, the upper ring 2 tends to squeeze out the tapered rollers 3 in the direction of their larger diameter. Due to variations in the dimensions of the rollers 3, which is due to inaccuracy of manufacture, the rollers 3 with a large diameter tend to move with great effort. Through the ball thrust bearing 7 and the stop 6, the radial force is perceived by the fluid in the cylindrical bore 5, which through the channel 10 flows into other cylindrical

15 holes where the diameters of the rollers 3 are smaller. Fluid overflow occurs: t until all rollers 3 have the same load. Thus, the axial load is distributed evenly between the rollers 3. With the removal of the axial load, the rollers 3 remain on the established raceways and the static load is distributed 25 seconds between all the rollers equally.

The rolling bearing is thrust according to E; the second variant works in the same way with the exception that the radial load is perceived: not by a liquid medium, but by cup-shaped wires 11.

Evenly distributed load between the rollers improves durability and reliability.
