To increase the load-carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, which shut off the lateral flow of the lubricating film in a partial region between the roll neck and the bearing surface of the roll neck bearing assembly, thereby bringing about an increase in pressure in the lubricating film. At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant.

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).

Oil outlets penetrating from an inner circumferential surface to an outer circumferential surface of a carrier ring are located in at least two of: a range that is on a forward side in a rotation direction of a rotary shaft from an upstream pivot and on a backward side in the rotation direction of the rotary shaft from a downstream pivot, a range that is from 180 degrees to 360 degrees and is from a position at a vertical height of the downstream pivot to a position at a topmost vertical height of the rotary shaft, or a range that is from 0 degrees to 180 degrees and is from a position at a vertical height of the upstream pivot to the position at the topmost vertical height of the rotary shaft.

A bearing assembly includes: a shaft; a housing; a support structure; at least one first seal; at least one electrode connected to the support structure and arranged between the support structure and the shaft such that an oil vapor from the oil bath, which passes through the at least one first seal, must pass through a gap between the at least one electrode and the shaft in order to escape, the bearing assembly being configured for an electrical voltage to be applied between the at least one electrode and the shaft so as to direct oil particles contained in the oil vapor onto the at least one electrode such that the oil particles are separated at the at least one electrode; and a drainage channel configured for enabling oil separated at the at least one electrode to flow through the drainage channel into the oil bath.
