A mounting device connects a rotary shaft to a rotatable machine element. The mounting device includes an inner sleeve for clamping onto the shaft and an outer sleeve for clamping onto the machine element. The inner and outer sleeves have cooperating tapered surfaces for tightening the mounting device. The cooperating tapered surfaces include striations. A nut connected with the inner and outer sleeves is rotatable to drive the inner sleeve relative to the outer sleeve in a first direction to tighten the inner sleeve onto the shaft and the outer sleeve onto the machine element.

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 drive train, specifically to a direct coupling of a drive shaft to a driven shaft provided in the drive train of a rotary compressor. Additionally, an integration of a lubricant circuit, including all associated channels and components, in the drive train.

The invention relates to a connecting arrangement for connecting a shaft to a component. A tapered outer surface of an inner ring and a tapered inner surface of an outer ring are configured in a manner corresponding to each other. The outer ring surrounds the inner ring. A union nut surrounds the outer ring and the threaded piece. The union nut has an internal thread and the threaded piece has an external thread, wherein the internal and the external threads are configured in a manner corresponding to each other.

An apparatus is provided for connecting a rotary shaft to a rotatable machine element. The apparatus includes and inner sleeve for clamping onto the shaft and an outer sleeve for clamping onto the machine element. The inner and outer sleeves have cooperating tapered surfaces for tightening the apparatus. The cooperating tapered surfaces include striations. A nut connected with the inner and outer sleeves is rotatable to drive the inner sleeve relative to the outer sleeve in a first direction to tighten the inner sleeve onto the shaft and the outer sleeve onto the machine element. A method is also provided for forming a mounting device for connecting a machine element with a rotary shaft.

A mounting device for coaxially anchoring a machine element upon a rotary shaft is provided. The device fits between the interior bore of the machine element and the cylindrical surface of the shaft and is effective to position the element at any desired position longitudinally of the shaft and at any angular position circumferentially of the shaft. The device has inner and outer sleeves, the mating surfaces of which are similarly tapered so that relative axial displacement of the sleeves affects expansion and contraction of the interior bore and external surface of the combined elements. Rotation of a threaded nut at one end of the device effects the relative axial displacement of the inner and outer sleeves to afford expansion and contraction of the sleeves without excessively straining the material of the sleeves or the nut.

A mounting assembly has a machine element with a threaded coaxial bore on a shaft, for rotation with the shaft. A split sleeve having external threads is provided and adapted to be fit into the element's threaded bore and mounted around the shaft at any desired position longitudinally and circumferentially. The threads of the split sleeve have apexes at a uniform diameter when unstressed. The threads of the split sleeve are shaped to cause contraction of the sleeve, when threaded into the element's bore, to secure gripping engagement with the shaft so that it frictionally clamps onto the machine element.
