The invention relates to a method for creating a press connection arrangement and a clamping connection, the method including a plurality of steps, as well as a press connection arrangement and a clamping connection per se.

A clutch for a lift fan with input and output shafts on a common rotational axis, connected by disc shaped output clutch plates oriented normal to the axis. A keyway extends radially inward from a mouth at an outer diameter of each output clutch plate to a seat at an inner diameter of the respective clutch plate. At least one output shaft lug key may be positioned in the keyway and extends axially from one output clutch plate to the other output clutch plate, which couples the rotation of the output clutch plates to the rotation the output shaft and allows axial movement of the two output clutch plates relative the output shaft lug key, the output shaft has an outer radial surface and an inner radial surface. At least one input clutch plate positioned axially between the two output clutch plates and rotationally fixed to the input shaft.

A composite bicycle crank with an integral spindle attachment structure provides a unique method for attaching a bicycle crank arm to a bicycle crank spindle, and also for attaching a bicycle crank arm to a crank arm insert. A light-weight crank arm is able to be manufactured separately from the crank spindle or insert, and then securely attached after both pieces have been made. This allows for the pieces of the crank assembly to be manufactured from one or more different materials, and securely connected after manufacturing, to create a lower weight assembly than would be possible otherwise.

A shaft-hub connection includes an alignment gearing with a plurality of dogs. The dogs comprise a contouring cross-section, which runs, at least partially, along a prolonged trochoid.

A shaft connection, e.g., for a motor vehicle driveline, comprises a metal shaft tube material and a metal connecting element. The connecting element comprises a connecting portion with an outer toothing which is pressed with a press fit into a connecting portion of the shaft tube so that an interlocking connection effective in the circumferential direction is formed for torque transmission, wherein the connecting element comprises a maximum outer diameter in the region of the outer toothing; wherein the shaft tube comprises an axial connecting region which is formed radially inwardly into a section of the connecting portion that is reduced relative to the outer toothing so that an interlocking axial connection effective in the axial direction is formed between the shaft tube and the connecting element for transmitting axial forces. A drive shaft can have such a shaft connection.

A rotor and a method of making such a rotor, wherein the rotor has a shaft, a longitudinal axis, and a rotor packet connected to the shaft at least in torsion-resistant manner. The rotor packet is assembled from individual sheet lamellae, wherein the rotor packet has an opening for receiving the shaft. The shaft is a hollow shaft with a wall, wherein the wall of the shaft has, on its side facing toward the opening, recesses extending in the longitudinal direction. An electric motor, in particular a synchronous or hybrid synchronous machine, including a rotor and a stator, has such a rotor. The recesses are produced by cutting methods, in particular milling, or reshaping methods, in particular pressing.

In order to provide a brake disc unit the production and assembly of which is economically viable even with extreme mechanical and thermal load capacity, preferably without the application of intermediate elements, the disclosure proposes a brake disc unit with a friction ring and a friction ring carrier which are connected by a shaft-to-hub connection with an alignment gearing having a multitude of dogs, wherein the cross-section of the dogs provides a contour which, at least partly, runs along an extended trochoid.

Disclosed herein is a control tube bearing assembly comprising in one example a main body having an outer surface, a longitudinal axis, a radial axis; and an actuator sleeve radially exterior of the main body longitudinally repositionable thereto. The actuator sleeve in use is grasped by a user and repositioned relative to the main body so as to actuate tape dispensing, mastic dispensing, creasing components, and/or tape cutting components or a taper as desired.
