Abstract: A spur gear transmission has at least two toothed spur gears, the toothings of which are in meshing engagement with one another and which are each rotatable about an axis of rotation. An enveloping wall encloses the two spur gears in a circumferential direction and in the direction of the axes of rotation. The enveloping wall has an inner contour which is adapted to the outer diameters of the spur gears such that ring-shaped gaps that merge into one another are formed between the enveloping wall and the spur gears. Each ring-shaped gap is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a multi-part housing which is closed along a parting joint. The parting joint extends partially or entirely substantially within a plane in which one of the two axes of rotation or both axes of rotation run.

Abstract: A radial plain bearing having a plurality of tilting pads for supporting a shaft, the tilting pads being movable relative to the bearing housing and being arranged circumferentially around and at a distance from the bearing axis, whereby the tilting pads have an outer radial plain bearing surface that can be supported on a supporting surface of a pressure block provided in the bearing housing; wherein the pressure block is movably provided in a passage extending radially through the bearing housing and can move radially without being supported on the bearing housing, the pressure block is secured against rotation in the circumferential direction of the passage by way of an anti-rotation element, and at least part or all of a radial outer surface of the pressure block is located on a common cylinder surface with an outer diameter of the bearing housing or with a bushing surrounding the bearing housing.

Abstract: The invention relates to a radial bearing, comprising a housing, a housing bore extending along a bearing axis, several tilting segments that are arranged around the bearing axis in order to support a shaft and each have a radially outer bearing surface, by means of which the tilting segments are supported on a supporting surface on the housing. The radially outer bearing surface of each tilting segment and the supporting surface are arranged facing each other. Each tilting segment is movably arranged relative to the housing.

Abstract: A method and arrangement for the transmission of data, in digital form, in a bus system, which includes a central unit, several stations, as well as a bus line or data bus. During operation, the following different transmission phases take place: An initiation phase, in which the central control unit queries all of the stations and prepares a request phase; the request phase, in which the individual stations report a required bus access; an allocation phase, in which each station obtains a time slot in response to its request; and a data phase, for transmission of the data. The central unit includes a phase control, a request collector, a time slot allocator, and a register. A number of the stations are provided with a request generator in such a way that the latter can signal a need to the bus access. Thus, an optimum utilization of the transmission capacity is achieved, possibly by switching stations off. However, a rapid bus access is possible at any time for important stations.
