A selector lever (7) is coupled to a transmission device for the axial displacement of the gearshift lever shaft (2), and a shift lever (4) is connected in a rotationally fixed manner to the gearshift lever shaft (2) for the radial rotation thereof. The transmission device comprises at least one engagement element (15) that is arranged axially on the gearshift lever shaft (2) and interacts with a coupling element (13), which is arranged on a free end of a straight or cranked section (12) of the pivotally supported selector lever (7).

The invention relates to a stub shaft arrangement for a twin-clutch transmission, which stub shaft arrangement comprises as such a stub shaft and hollow shaft which accommodates the latter in certain sections. The invention is based on the object of specifying solutions which permit the mechanical operating behaviour of a twin-clutch transmission to be improved with a degree of outlay which is acceptable in terms of fabrication and mounting. This object is achieved according to the invention by means of a stub shaft arrangement for a twin-clutch transmission having a hollow shaft, a stub shaft which is inserted into the hollow shaft and has an excess length protruding beyond an end of the first hollow shaft, a hollow shaft bearing for supporting the hollow shaft in the radial direction, a first stub shaft bearing for supporting the stub shaft in the hollow bearing, wherein the first stub shaft bearing is arranged on a side of the hollow shaft bearing facing away from the excess length, and a second stub shaft bearing which is seated in the area in which the hollow shaft bearing engages around on the stub shaft, wherein this stub shaft arrangement is distinguished by the fact that a third stub shaft bearing is provided in the axial direction between the hollow shaft bearing and the excess length, and that this third stub shaft bearing is embodied as a sealed bearing. This makes it advantageously possible to provide a twin-clutch transmission in which even relatively large transverse forces which act on the stub shaft do not bring about severe axial offset of the axle of the stub shaft with respect to the axle of the hollow shaft which supports the stub shaft. As a result, the smooth running of the stub shaft within the hollow shaft is increased in a surprisingly effective way.
The invention relates to a device for compensating axial thermal expansions of a rolling bearing arrangement.

AUTO-BALANCING DEVICE FOR IMBALANCE COMPENSATION IN SEPARATORS OR CENTRIFUGES, AND SEPARATOR OR CENTRIFUGE HAVING AN AUTO-BALANCING DEVICE OF SAID TYPE
The invention relates to an auto-balancing device (06) for imbalance compensation in a separator or in a centrifuge. The auto-balancing device (06) comprises an imbalance compensating disk (07) which surrounds the driveshaft (02) of the separator and which has an annular cavity (08) and a plurality of balancing masses (09) which are freely movable in the cavity (08) and which compensate the existing imbalance by assuming an opposing position.

The invention is based on the problem of proposing an angular-contact ball bearing which has reduced friction losses. Proposed is an angular-contact ball bearing (1) having an inner running surface (6), having an outer ring (3) with an outer running surface (7), having a cage (5) and having a multiplicity of balls (4), wherein the balls (4) are mounted in the cage (5) so as to be able to roll between the inner running surface (6) and the outer running surface (7), wherein the outer ring (3) has a cage guiding surface (9) which is designed to guide the cage (5), and wherein the outer ring (3) has a plurality of cage lubricating ducts (12) whose outlet openings (13) extend through the cage guiding surface (9), and wherein the cage lubricating ducts (12) are designed for transporting an oil-air mixture.
The invention relates to a sealing device (1) for a rotary bearing, having two sheet-metal rings (2, 3) which have a substantially L-shaped partial cross section and can be moved in relation to one another, wherein an elastic sealing means (4) with sealing lips (7, 8) is arranged at least on one sheet-metal ring (2, 3). In order to prevent the multi-part sealing device (1) from becoming damaged or falling apart, for example during transportation, during fitting to a rotary bearing and/or during transport or operation of the rotary bearing, the invention provides a latching connection to the first and second sheet-metal rings (2, 3), and this captively holds said components together after they have been assembled.
The invention is based on the object of developing an angular-contact ball bearing in a tandem arrangement and a corresponding bearing arrangement. The invention proposes an angular-contact ball bearing (1) having an outer ball row (5), an inner ball row (4) and at least one common bearing race (2) which guides the two ball rows (4, 5), wherein the outer ball row (5) is guided in the angular-contact ball bearing (1) by a two-point bearing arrangement and the inner ball row (4) is guided in the angular-contact ball bearing (1) by a four-point bearing arrangement, and wherein the balls of the outer ball row (5) have a larger diameter than the balls of the inner ball row (4).

The invention relates to an anti-friction bearing (1) having a brake device, in particular a revolving joint, consisting of a bearing outer ring (2) and a bearing inner ring (3) between which anti-friction elements roll on associated raceways, wherein a braking effect by means of frictional engagement is achieved by pressing a displaceable brake element, which is connected to one of the bearing rings (3, 2) and has a brake lining (15), against a opposing surface (23), which is connected to the other bearing ring (2, 3). According to the invention, the opposing surface (23) is provided with a friction-increasing coating (24) which consists of a base material (25) and at least one incorporated additional material (26).
