Vertical shaft with a slide bearing for a turbine or a generator

摘要

A vertical shaft with a slide bearing for a turbine or generator. The invention relates to a vertical shaft (1) with a hydrodynamic slide bearing (2) comprising the following features or components: •—an annular fixed bearing housing (3) which surrounds the shaft (1); •—a plurality of bearing segments (4) which are fixed components of the bearing housing (3), surround and support the shaft (1) and form a bearing gap (5) therewith; •—the shaft (1) has a radially inner oil trough (1.2) and radially outer oil trough (1.3) communicating therewith; •—an oil lubrication system in which the oil flows through the following components: •—the bearing housing (3); •—a first connection line from the bearing housing (3) to the inner oil trough (1.2); •—an overflow channel (1.4) from the upper end of the radially inner oil trough (1.2) to the upper end of the radially outer oil trough (1.3); •—bores (7) from the radially outer oil trough (1.3) to the bearing housing (3); •—and a cooling device (10) with connections to the bearing housing (3). The invention is characterised by the following features: •—a scoop shovel is provided, which is a component of the guide pipe; •—the guide pipe (9) is a component of a conducting connection between the bores (7) and the cooling device (10).

1. A vertical shaft with a hydrodynamic slide bearing, comprising:
an annular fixed bearing housing, which surrounds the shaft; a plurality of bearing segments, which are fixed constituents of the bearing housing, which surround and support the shaft, and form therewith a bearing gap; the shaft has a radially inner oil trough as well as a radially outer oil trough communicating therewith; an oil lubrication system, in which the oil flows through the following components:
the bearing housing;a first connection line from the bearing housing to the inner oil trough;an overflow channel from the upper end of the radially inner oil trough to the upper end of the radially outer oil trough;bores from the radially outer oil trough to the bearing housing;a cooling device with connections to the bearing housing, comprising:a scoop shovel is provided, which is a component of a guiding pipe;the guiding pipe which is an integral part of a conducting connection between the bores and the cooling device.
