Abstract: A planetary gear train which includes a planet carrier having at least one radial wall with pin bores formed therein, planetary gear pins that are seated in said pin bores on at least one end, planetary gears that are arranged on the planetary gear pins, and a ring gear that is attached to the radial wall and dimensioned such as to rise radially above an inner enveloping circle of the pin bores. The radial wall carrying an annular collar and the ring gear is axially secured to the annular collar.

Abstract: Angular contact ball bearings are disclosed. In one example, the angular contact ball bearing may include an inner ring having an inner ring raceway and an outer ring having an outer ring raceway. A plurality of balls may roll on the inner and outer raceways. A cage may guide the plurality of balls in a plurality of closed pockets, wherein each ball is accommodated in one of the closed pockets. The bearing may include a plurality of projections, wherein each projection extends radially toward the raceway of the outer ring between every two adjacent, closed pockets. The cage may be guided on the outer ring raceway by the projections.

Abstract: The invention concerns a rolling bearing (1; 1?) with a one-piece outer bearing ring (3) and a one-piece inner bearing ring (2), and with rolling elements (4) arranged in at least one row between the bearing rings (2, 3). Provision is made in this rolling bearing that the outer bearing ring (3) and/or the inner bearing ring (2) has, on the axial end face, at least one cutout (10) through which the rolling elements (4) can be placed into the space between the bearing rings (2, 3), that the cutout (10) can be covered with a reversibly attachable cap (9), and that the cap (9) forms a rim (11) for guiding the rolling elements (4). The lateral cutout (10) for filling the rolling bearing (1) with rolling bodies permits cage solutions of segmented or strip design that are larger than a rolling element and hence can accommodate multiple rolling elements. The suitability of the rolling bearing for high rotational speeds and the stiffness of the rolling bearing are increased as a result.

Abstract: A mammography unit having a mounting arm, on which a mounting for at least two X-ray receivers is rotatably disposed in such a way that one X-ray receiver at a time is positioned in an examination position inside an intended X-radiation field, while other X-ray receivers each remain in a reserve position outside the X-radiation field, is provided. The at least one reserve position is disposed on a side located in the X-radiation direction, relative to the mounting arm. In the case of two X-ray receivers, the X-ray receivers each form a lateral angle of between 45° and 90° with the axis of rotation of the mounting. By using a releasable connection of the mounting to the mammography unit, high modularity is provided.
