Abstract: A permanent magnet rotor of an electric motor, includes a laminated core having magnet pockets, the laminated core being composed of two partial laminated cores. A plurality of permanent magnets are held in a force-fitting manner in magnet pockets of the laminated core, the magnets extending over both partial laminated cores. Sheet metal tongues, which maintain the force fit of the permanent magnets, are deflected in the first partial laminated core in a first axial direction and in the second partial laminated core in a second axial direction opposite to the first direction, wherein the partial laminated cores consist of stamped metal sheets and the permanent magnets are pressed into the magnet pockets in the stamping direction.

Abstract: A stator of an electronically-commutated DC motor, with a stator core, an insulating cap, a stator winding, and a winding interconnection, wherein the winding interconnection consists of several sheet-metal elements and several insulating elements which are arranged between the sheet-metal elements. The aim of the invention is to provide a simple design for a generic stator consisting of easy-to-manufacture and easily-shaped components, wherein production tolerances can be compensated for in a simple manner. A further aim consists of being able to use reliable and proven production processes which are also as easy as possible to monitor.

Abstract: An apparatus for smoothing an inner toothing and/or an outer toothing of a component part. At least two radially adjustable smoothing gears, which engage in the inner toothing and/or outer toothing, are rotatably arranged inside the inner toothing and/or outside of the outer toothing. During smoothing, the component part is not firmly clamped but rather only rests loosely on a support. A thrust ring is provided at least at one of the smoothing gears for limiting axial movements of the component part, which occur during smoothing.

Abstract: A positively-locking connection between two components of a transmission that have round cross-sections, designed to support axial forces. A first component to be connected has an annular flange with windows stamped out around its circumference. The windows enable simple deformation of the annular flange. The second component to be connected has an annular groove such that after bringing the two components together, the annular flange of the first component, when viewed axially, is positioned over the annular groove of the second component, such that the annular flange of the first component can be pressed radially into the annular groove of the second component so that segments of the annular flange radially engage the annular groove.

Abstract: The invention is directed to a microscope objective with axially adjustable correction mounts and is applicable in connection with different cover slips and/or different immersion liquids and/or at different work temperatures. In the microscope objective according to the invention, helical springs which are uniformly distributed along the circumference and act in axial direction are fixed by a first ring which has pins in axial direction on which the helical springs are arranged. The pins engage in bore holes of a second ring. The bore holes are at least deep enough to ensure the required spring path. The two rings with the helical springs arranged therebetween on the pins form a spring retainer which ensures a movement of the parts without play and/or in a springing manner. In principle, the proposed solution can be substituted for all pressure springs in microscope objectives and other objectives and can overcome the disadvantages of using individual springs.
