Problems solved by technology

[0003] The known solutions are not perfect in that there is only little installation space available for adjusting the bearing preload or the corresponding bearing play (Lagespiel), which makes it relatively difficult to install and adjust the necessary components

specific Embodiment approach

[0066] The force that needs to be introduced via the adjustable ribs 10 , 11 in order to obtain the desired pretensioning of the rolling elements is generally about an order of magnitude smaller than the force required for pretensioning the inner rings 4 , 5 . This allows the invention to adopt a specific embodiment: especially in large bearing units, for example, the ribs 10, 11 provided with the thread 15 can be axially adjusted according to the operating state by means of a servomotor (then of course without the aid of a device 20, 21), so that there is always an optimum preload in the bearing unit.

Abstract

The invention relates to a bearing combination unit, which includes two pairs of rolling bearings. The rolling bearing has an inner ring, an outer ring and a rolling element arranged between the bearing rings. The two pairs of rolling bearings can be moved relative to each other in the axial direction by the inner ring and / or the outer ring. The movement is preloaded, ribs are provided on the inner ring and / or outer ring, forming an axial stop for the rolling elements, and at least one of the ribs is axially adjustable relative to the bearing ring used to carry it. Ground is set on the bearing ring. In order to be able to adjust the preload in the bearing assembly unit more simply and more accurately and at the same time to have enough space for the required components, the invention proposes a rib that is movable relative to the bearing ring and is configured as a retaining ring, with a first segments, the first segment can move on the bearing ring through the slide seat, and the rib has a second segment axially adjacent to the first segment, the second segment has a thread, the thread can cooperate with the thread contained in the independent component The threads are engaged, and the independent components are spaced apart from the bearing ring in the axial direction.

Description

technical field [0001] The invention relates to a bearing combination unit, which comprises two sets of rolling bearings, each set of rolling bearings has an inner ring, an outer ring and rolling elements arranged between the bearing rings, wherein the two sets of rolling bearings can pass through the inner ring and / or the outer ring. The relative movement of the rings in the axial direction is preloaded (vorgespannt), and the inner and / or outer rings are provided with ribs (Borde), which form axial stops (Anschlag) for the rolling elements, and the ribs At least one of the ribs is axially adjustably arranged on the bearing ring relative to the bearing ring for carrying it. Background technique [0002] A bearing combination unit of this type is known from DE 10 2012 221 297 A1. With this known solution it is possible to axially preload two interacting roller bearings, in particular tapered roller bearings, against each other. In this case, the adjustment of the preload is...
