Abstract

The invention relates to electrical engineering. The purpose of the invention is to increase the durability and reliability of the bearing assembly in operation. A bearing unit with an autonomous lubrication system for a horizontal high-speed electric machine contains an oil bath 1, a lubricating ring 2 and an oil-separating element. Due to the fact that the oil separating element is designed in the form of a box having a transverse wall located in the oil bath between the lubricant ring 2 and the holes 13 in the vertical wall 11 of the bath, this goal is achieved. 5 il.

11 baths, the goal is achieved. 5 il.

The invention relates to electrical machinery H1-sh and can be used in horizontal high-speed electric machines with a power of 500-1000 kW with an autonomous non-circulating lubrication system.

The aim of the invention is to increase the operational reliability of the bearing assembly.

FIG. 1 shows the bearing assembly, general view, section; FIG. 2 is a view A of FIG. 1, FIG. 3 - section B-B on phi1. 2; on needle, 4 - section bb in fig. 2; in fig. 5. - oil separating box, general view in isometry. -

A bearing assembly with an autonomous non-circulatory (annular) lubrication system for a horizontal high-speed electric machine contains an oil bath 1, a lubricating ring 2, a back cover 3, an insert 4, a scraper 5,

The pressed oil separating box 6 includes a vertical wall 7 with openings 8 for fastening the box, a vertical wall 9, a horizontal partition 10.

 The oil separating box is made pressed, for example, from plastic and removable. It is mounted on the wall 11 of the oil bath 1. This wall 11 is the bearing support. The box has 7 and 9 vertical and 12 transverse walls. The horizontal partition 10 is located in the oil bath 1 between the lubricating ring 2 and the opening 13 in the wall 11. The box 6 is attached to the vertical wall 11 with pins 14, One of its transverse walls is located on the end of the vertical walls, and another from the bottom of the partition 10 .

The device works as follows.

When the shaft of the electric machine is rotated, the lubricating ring 2 rotates and, with its internal and external surfaces, lifts 1 oil out of the oil bath and supplies it to the screen: b-5. Using the scraper 5, the oil is

goes into the hole in the liner 4. The oil, falling into the gap between the shaft and the liner, is heated during operation. The waste heated oil through the system of holes (not shown) and the gaps flow between the lid 3 and the wall 11. under the horizontal partition 10 in space, limited to the specified horizontal partition 10 and the vertical wall of the oil separation box 6.

The oil bypasses the vertical wall and begins to cool, flushing the surface of the oil bath 1. The cooled oil passes into the zone bounded by the horizontal wall 10 and the vertical wall 9, and enters the working zone of the lubricant ring 2..

Then the process of moving the oil is repeated.

The proposed design of the bearing assembly with a self-contained non-circulating lubricant for a horizontal high-speed electric machine is highly reliable and durable by improving the cooling of the oil and the possibility of cleaning the oil from mechanical impurities, since the oil separation box is removable. In the process of operation of the bearing unit, the mechanical inclusions are deposited in the zone formed by the horizontal partition 10 and the vertical wall of the oil separating box 6.
