The invention relates to a compressor machine (), in particular a generator or a compressor unit for compressing a gas, comprising a shaft () which is arranged in a housing () so as to be able to rotate about a longitudinal axis () and which is mounted in at least two radial bearings () and a thrust bearing (), the radial bearings () and/or the thrust bearing () being in the form of an aerodynamic or aerostatic bearing, the shaft () being at least indirectly connected to a compressor stage () or driving stage comprising an impeller wheel ().

Compressor with thermal expansion reducing structure

The invention relates to a shaft-hub connection (), particularly for mounting a rotor wheel on a shaft (). The shaft-hub connection () comprises a shaft (), a hub () and a filler material (). The shaft () comprises an end section () on one end. A receiving region () is arranged in the hub (). The end section () is arranged in the receiving region (), with an intermediate layer of the filler material () positioned inbetween. The filler material () forms undercuts in the axial and rotational direction, in relation to the end section () and in relation to the receiving region (), so as to create a positive embodiment of the shaft-hub connnection ().

Shaft-hub connection

The approach which is proposed here relates to an adjusting sleeve () for a bearing device () having at least one housing () for receiving a bearing sleeve (), the bearing sleeve () for receiving a shaft (), and the shaft (). The adjusting sleeve () is configured to be capable of being received between the bearing sleeve () and the housing () and to be thermally conductive. To this end, an outer wall () of the adjusting sleeve () has at least one outer depression () which is configured to produce an outer chamber () between the adjusting sleeve () and the housing () in a received state of the adjusting sleeve () in the bearing device (), and/or an inner wall () of the adjusting sleeve () has at least one inner depression () which is configured to produce an inner chamber () between the adjusting sleeve () and the bearing sleeve () in the received state of the adjusting sleeve () in the bearing device ().

The invention relates to a method for operating a ground-coupling arrangement for a vehicle comprising a ground receiving element for receiving a grounding object, wherein the ground receiving element is at least partially filled with a fluid which contacts the grounding object; at least one coupling means which is designed for coupling the grounding object to the ground receiving element by means of the fluid and thus to a vehicle structure that is rigidly connected to the vehicle, and/or for at least partially decoupling of the ground receiving element from the vehicle structure; and a hydraulic line which connects the coupling means to the fluid, wherein the grounding object compresses the fluid in the case of a crash and the coupling means directs the fluid out of the ground receiving element or reroutes the fluid in the ground receiving element.

Mass-coupling arrangement for a vehicle

A sheet-fed, rotary, printing press for printing on both sides of sheets without a sheet reversing device, includes printing units having a modular construction. Each module includes at least a plate cylinder, a blanket cylinder, an impression cylinder, a transfer cylinder and at least one drive wheel. Modules for printing on the first side of the sheets and modules for printing on the second side of the sheets have an identical construction and are disposed in such a way that one is rotated through 180&#xb0; relative to the other about an axis extending in a sheet processing direction.

A rotary printing machine includes a first gearwheel, a second gearwheel, and a setting device for selectively adjusting the second gearwheel into a first position, in which the gearwheels are coupled to one another, and into a second position, in which the gearwheels are uncoupled from one another. The printing machine includes a traction mechanism for securing a staggered-teeth rotary-angle position of the second gearwheel relative to the first gearwheel when the second gearwheel is adjusted into the second position, and a first tension element for tensioning a rotatably arranged traction means of the traction mechanism. The first tension element is loaded by a spring. The traction means is assigned a second tension element, and in the second tension element is mounted so to be a selectively adjustable into a first switching position and a second switching position.

A method of operating a sheet-fed rotary printing machine includes mounting at least one rotating cylinder to be coupled to a drive or fixed relative to a framework, and moving an actuator to both uncouple the cylinder from the drive and fix the cylinder relative to the framework. A sheet-fed rotary printing machine includes a framework, a drive, at least one cylinder rotatably mounted to the framework, the cylinder is to be coupled to the drive or fixed relative to the framework, and a fixing and coupling configuration connected to the cylinder to both uncouple the cylinder from the drive and fix the cylinder relative to the framework.
