Abstract: An actuator for a control unit has a control motor with a motor power takeoff shaft; a control shaft that carries the control unit; and a step-up gear, disposed between the motor power takeoff shaft and the control shaft, as well as a restoring device for restoring the control unit to a basic position if the control motor fails. To make it possible to use a single-stage step-up gear with a major step-up ratio and with advantages in terms of installation space, weight, and production costs, the restoring device has two separate energy-storing means, preferably embodied as restoring springs, of which one feeds back to the motor power takeoff shaft and the other feeds back to the control shaft.

Abstract: Bearing device, especially for a gear A bearing device, especially for a gear, comprises a housing part (8) made of plastic, a bearing shell (1) with a cylindrical sheath-shaped ring section (2) as well as a radial section (3) held in the housing part (3) adjoining this, an inner shaft (6) guided in the bearing shell (1) on a first journal (9) and a second rotatable part (11,16) guided on a second journal (10) of the bearing shell (1), surrounding the inner shaft.

Abstract: The invention relates to a coupling for coupling two rotatable bodies, in particular a gear and a drive shaft, which are disposed essentially concentric to each other, with or without axial offset, having a coupling part. In order to reduce the structural height of the coupling, the coupling part is integrated into one of the rotatable bodies. In a fuel-supply pump, the drive shaft is coupled to the driven gear by means of the coupling part.

Abstract: A cutting tool of the specified type is to be miniaturized and configured in such a manner that it is suitable for working bores having a diameter of 6 mm and more and for high-speed work with revolving tools.The solution according to the invention provides that the adjustment screws for radially adjusting the cutting plate simultaneously form a clamping means for the form-locking clamping of the cutting plate to the supporting shoulder of the basic tool body.A preferred field of use are precision drills and grinding tools equipped with inserted cutting strips made of a highly wear resistant cutting material.
