A universal joint shaft with universal joint shaft protection comprises at least one shaft element for transmitting torque, at least one protective tube element arranged around the shaft element, and an intermediate bearing, by means of which the shaft element is rotatably mounted about an axis of rotation (L) in the protective tube element, wherein the intermediate bearing comprises an outer ring fixed to the protective tube element and an inner ring fixed to the shaft element, which are rotatable relative to each other, and a clamping mechanism by means of which the inner ring is fixed on the shaft element.

A clamping arrangement for the force-fit connection of an outer component to an inner component including an inner conical ring and an outer conical ring wherein one of the rings has leadthrough bores clamping screws and the other ring has threaded bores for the clamping screws to brace the rings against one another via the conical peripheral surfaces, and against the inner and outer component arrangement. At least one leadthrough bore having an ejector thread for an ejector screw and the diameter of the ejector thread being greater than the diameter of the clamping screw. The arrangement including an ejector ring with an ejector bore for the leadthrough of the ejector screw which can be screwed into the ejector thread and an ejector surface for engaging a clamping screw head that is incompletely screwed into the corresponding threaded bore for the transmission of an ejector force onto the clamping screw.

A press includes two components and a clamping element insertable in an axial direction, via an actuating element which is axially displaceable via an actuator, radially between a region of the first component and a region of the second component. The actuating element passes through the components and the clamping element in the axial direction. The actuating element at one end cooperates with the actuator and at the other end includes a cover element via which the actuating element is actively connected to the components. The clamping element is arranged between the cover element and the components, or between the components and a housing region of the actuator. The actuating element and/or the actuator is movable by the actuator, for insertion of the clamping element between the components, in a scope reducing an axial distance between the cover element and the housing region of the actuator.

A frictionally locking shaft/hub clamping connection (1) having at least two cone clamping rings (4, 5) which bear against one another on their cone faces (4a, 5a) and can be pushed onto one another axially by way of clamping elements (6), the radial forces which are produced bringing about a frictionally locking connection between the shaft (2) and the hub (3). The cone faces (4a, 5a) of the clamping rings (4, 5) which bear against one another have a non-round cross section which differs from the circular shape.

An improved bushing assembly comprising an inner bushing having an outwardly-facing frusto-conical surface, an outwardly-facing threaded surface, and an inwardly-facing cylindrical surface adapted to engage a shaft, an outer bushing having first and second bushing bearing surfaces and an inwardly-facing frusto-conical surface in sliding engagement with the outwardly-facing frusto-conical surface of the inner bushing, a nut having an inwardly-facing threaded surface in mating engagement with the outwardly-facing threaded surface of the inner bushing and first and second nut bearing surfaces radially overlapping the first and second bushing bearing surfaces of the outer bushing, whereby rotation of the nut in first and second rotational directions relative to the inner bushing moves the outer bushing in first and second axially directions to operatively tighten or untighten, respectively, the inner bushing around the shaft.
