SU1428856A1 - Arrangement for lubricant circulation greasing - Google Patents

Abstract

The invention relates to mechanical engineering and can be used in bearing assemblies and other devices with grease. The goal is to increase the effectiveness of the lubrication process. The device includes a housing 1, in which a bearing assembly with a shaft, covers, flexible diaphragms 8, 9 and activators 10, 11 are installed. Activators are made in the form of disks 12, 13 with radial projections 14, 15 that are offset relative to each other. in the circumferential direction. Activators can be made in B1 of disks with radial hollows in which rollers are placed. When a shaft rotates, a running wave of microstrain appears on the diaphragms. The lubricant from the chamber 21 is displaced by a corresponding diaphragm into the bearing assembly and then into the chamber 22. Due to the fact that the protrusions of the activators are displaced in the circumferential direction, part of the lubricant from the chamber 22 is displaced into the bearing assembly. On the working surface of the bearing assembly, made in the form of a sliding bearing, there is at least one transverse groove open to the diaphragms. 3 h, para. f-ly, 7 ill. with tS (L

Description

of a lubricant containing a housing, a bearing assembly, an end cap, a shaft, a flexible diaphragm installed in the housing and fixed in the end cap, and an activator mounted on the shaft, between the end cap and the subelectronic assembly with the ability to interact with the flexible diaphragm, differing This is because, in order to increase the efficiency of the lubrication process, the device is equipped with additional activator and diaphragm, located on the opposite side from the bearing depressions of the activator,

3. Device - according to paragraphs. 1 and 2, about t - l and h and e with the fact that the number of protrusions and hollows on opposite

activator does not match.

4. Device pr pp. 1-3, characterized in that, in order to increase the efficiency of the lubrication process of the loaded area of the bearing assembly, made in the form of a sliding bearing, at least one transverse groove is made on the working surface of the bearing, open towards the diaphragms,

Claims (4)

Claim 1. A device for a plastic circulation lubrication cirque comprising a housing, a bearing assembly, an end cap, a shaft, a flexible diaphragm mounted in the housing and secured in the end cap, and an activator mounted on the shaft between the end cap and the bearing assembly with the ability to interact with a flexible diaphragm, characterized in that, in order to increase the efficiency of the lubrication process> 20, the device is equipped with additional activator ”and a diaphragm located on the opposite side from the bearing assembly, ktivatory formed as disks with radial projections and recesses facing the diaphragm, and the projections on opposite activators are offset relative to each other in the circumferential direction. 2. The device according to π. 1, characterized in that it is equipped with rollers placed in the radial depressions of the activator. 3. The device according to claims 1 and 2, characterized in that the number of protrusions and depressions on the opposite activators does not coincide. 4. The device according to. p. 1-3, characterized in that, in order to increase the efficiency of the lubrication process of the loaded zone of the bearing unit, made in the form of a sliding bearing, at least one transverse groove is open on the working surface of the bearing, open towards the diaphragms'. view A FIG. 2 FIG. 3 in id b FIG. 6
