(54) BEARING PUMP ASSEMBLY WITH VERTICAL SHAFT (57) The invention improves the reliability of the assembly by increasing lubricant consumption. When the shaft 2 rotates, the intake device, made in the form of inclined channels-slits 9 in the sleeve 4, runs over the lubricant, creating a pressure in the axial channels 5. Vertical ribs prevent the lubricant from twisting 7. Bath silt

This invention relates to a hydraulic engineering industry, in particular the construction of lubrication units for pump bearings.

The purpose of the invention is to increase reliability by increasing lubricant consumption.

FIG. 1 shows a bearing assembly, longitudinal section; in fig. 2 is the same cross section: in FIG. 3 - locking device, longitudinal section; in fig. 4 - section of the sleeve along the axial channels.

The bearing assembly of the pump with a vertical shaft includes a housing 1, mounted between the shaft 2 and the bearing 3, an elongated sleeve 4 with axial channels 5 and intake devices, the inlet portions 6 of which are oriented in the direction of rotation, and a bath 7 for lubrication. made in the case.

The assembly is provided with vertical ribs 8 mounted on the housing and arranged around the sleeve 4, and the intake devices are in the form of channels 9 inclined to the plane of rotation and communicated with axial channels 5. The assembly can be equipped with a retaining ring 10 connecting the upper ends of the vertical edges 8. The inclined channels 9 are made in the form of slots in the sleeve 4.

Bearing unit works as follows.

The sleeve 4 under the bearing 3 is mounted on the shaft 2 and immersed in the bath 7 between the housing 1 and the vertical ribs 8. When the shaft 2 rotates, the intake device attaches grease, which, the passage through it and the axial channel 5, is thrown onto the bearing 3. through the bearing 3, lubricating and cooling it, the lubricant returns to the bath 7, from which between the ribs 8 approaches the intake device.

The vertical ribs 8 prevent the lubricant from twisting in the bath 7.
