Abstract

The invention relates to the field of mechanical engineering, namely to structures of bearing assemblies operating on grease. The purpose of the invention is to improve the lubrication conditions of rolling bearings by directly supplying it to the working surfaces of the rolling bodies. This is achieved by elastic elastic washers 5 with elastic rods 6 made on the inner end surface of the washers in the form of a multi-flange. Washers are placed on both sides of the bearing with the possibility of contact with the inner I and outer 2 rings of the bearing 1. The elastic rods 6 of the washers 5 are in contact with the balls 4. The space between the rods is filled with a consistency} with this lubricant. When the bearing assembly is in operation, the elastic rods of the multi-flange under the influence of the balls 4 and the separator 3 exhibit oscillatory movements.

Description

The invention relates to a design, and namely to the design of bearing units operating on grease.

The purpose of the invention is to improve lubrication conditions due to its immediate delivery to the working surfaces of rolling bodies and its uniform distribution in the volume of the bearing assembly,

Fig. 1 shows the design of the bearing assembly; figure 2 - the location of the elastic rods on the inner surface of the elastic elastic washers.

The bearing assembly includes a bearing containing inner 1 and outer 2 rings, separator 3, balls 4, elastic spring washers 5, on the inner end surface of which elastic bars 6 are placed in the form of a multi-flange with the possibility of contact with rolling bodies, plate 7, and the claws 8 and the bearing housing 9; Elastic spring washers and plates are pressed against the end surfaces of the ring 2 of the collision chamber 8, which are attached to the housing 9; The bearing cavity is sealed by the washers 5 Nost m bearing rings. The space between the rods 6 is filled with grease in the amount of not more than 1/3 of the free volume of the bearing. When assembling the bearing assembly, due to the direct contact of the elastic rods with the balls and the separator, a part of the lubricant falls on the working surfaces of the rolling bodies.

When the bearing unit is in operation, the balls with the separator move relative to the stationary multi-flange in contact with them. In this case, the elastic rods of the comb under the influence of the balls and the separator perform oscillatory movements. In this case, particles of grease fall on the working surfaces of the bearing and lubricate them.

The use of a bearing assembly allows for improved lubrication conditions for the ball bearing.
