F16C 19/38 - Bearings with rolling contact, for exclusively rotary movement with bearing rollers essentially of the same size in one or more circular rows, e.g. needle bearings for both radial and axial load with two or more rows of rollers
The invention relates to an adjustment unit of a steering column of a motor vehicle, in which a steering spindle is mounted to be rotatable about a longitudinal axis and has a casing unit (2) that has at least three casing tubes (3, 4, 5) which are arranged so as to be axially telescopable relative to one another and one of which forms an outer casing tube (3) in which at least one intermediate casing tube (4) is received in which an inner casing tube (5) is received, wherein a motor (6) for adjusting the casing unit (2) is provided, the motor (6) is connected to the casing unit (2) and to a housing (8) that receives a spindle (7), and the motor (6) actuates the spindle (7).
The invention relates to a rotary-table bearing assembly comprising a rotary-table bearing (10), in which assembly a clamping device (33) acts on a shaft disc (30) in such a way that a tangential moment acting on the rotary-table bearing (10) can be compensated by a tangential resisting moment. To this end, a pressurised medium can be introduced via a channel (43) and an inlet (39) into a chamber (37) which is surrounded by a ring (35) and sealed by seals (45) and has a membrane (31) having a surface (31a). The surface (31a) of the membrane (31) has a high coefficient of friction and can make contact with an axial surface (30a) of the shaft disc (30). The membrane (31) can return to its original shape when the pressure in the pressurised medium is reduced or using an additional component such as a return spring (41).

F16B 2/02 - Clamps, i.e. with gripping action effected by positive means other than the inherent resistance to deformation of the material of the fastening
F16C 19/54 - Systems consisting of a plurality of bearings with rolling friction
A strut bearing assembly and an improved cap for a strut bearing assembly is disclosed herein. The cap defines a first bearing pocket half dimensioned to receive a first portion of a bearing assembly, a radially outer edge defining a first mating element configured to mate with a first portion of a top mount, and a radially inner projection defining a bearing surface configured to abut a second portion of a top mount. The top mount component can generally be configured to attach to a car body. The strut bearing assembly can include a guide ring including a guide sleeve configured to provide an interface for a shock absorber spring. The guide ring can define a second bearing pocket half dimensioned to receive a second portion of a bearing assembly.
B60G 15/06 - Resilient suspensions characterised by arrangement, location, or type of combined spring and vibration- damper, e.g. telescopic type having mechanical spring and fluid damper
F16C 19/14 - Bearings with rolling contact, for exclusively rotary movement with bearing balls essentially of the same size in one or more circular rows for both radial and axial load
A planetary gearbox for a wind power apparatus has a planetary shaft (10), a planetary gear (50), and a planetary carrier (60). The planetary shaft (10) is mounted on the planetary carrier (60), and the planetary gear (50) is mounted on the planetary shaft (10), wherein modification areas (101, 102, 501, 502) are provided in the axial contact area between the planetary gear (50) and the planetary shaft (10) and on the inner circumferential surface of the planetary gear (50) and/or on the outer circumferential surface of the planetary shaft (10). The structure of the planetary gearbox can reduce edge stress concentration and extend the service life of the system.
A rolling-bearing element (1), in particular a bearing ring, has a multiplicity of 3D-printed layers (7, 11, 12), wherein at least a sub-quantity of these layers (7, 11, 12) is built up from a plurality of layer portions (8, 9, 10) which are arranged one beside the other in the relevant layer (7, 11, 12) and are made of different materials, and wherein identical layer portions (8, 9, 10) in a plurality of these layers (7, 11, 12) are arranged directly one above the other, and this results in material layering in a direction transverse to the build-up of the 3D-printed layers (7, 11, 12).
The invention relates to a rotary-table bearing assembly comprising a rotary-table bearing (10), in which assembly a clamping device (33) acts on a shaft disc (30) in such a way that a tangential moment acting on the rotary-table bearing (10) can be compensated by a tangential resisting moment. To this end, a pressurised medium can be introduced via a channel (43) and an inlet (39) into a chamber (37) which is surrounded by a ring (35) and has a membrane (31) having a surface (31a). The surface (31a) of the membrane (31) has a high coefficient of friction and, owing to a build-up of pressure in the chamber (37), can make contact with a radial surface (30a) of the shaft disc (30). By reducing the pressure or using an additional component such as a return spring (41), the membrane (31) can return to its original shape.
