A connection for connecting a first member with a second member, including a torque transmitting connection between the first member and the second member and an axial force transmitting connection between the first member and the second member, wherein the axial force transmitting connection includes a first exterior shoulder on the first member, a second exterior shoulder on the second member, a first collar having a first interior shoulder for engaging with the first exterior shoulder, a second collar having a second interior shoulder for engaging with the second exterior shoulder, and a collar connection between the first collar and the second collar for transmitting an axial force between the first collar and the second collar.

In order to simplify the design of an aircraft turbo engine propeller while enhancing the safety function thereof related to control of the blade angle of attack, a propeller is provided comprising a secondary rotational coupling to couple in rotation, along the radial axis of the blade, the inner radial end of the blade root with a mechanical joining member of a blade angle of attack control device, the secondary coupling being designed and configured to be active in the event of failure of the main pin.

A torque transmission member for transmitting torque between a first rotating member and a second rotating member is provided. The torque transmission member has a first connection part and a second connection part which are concentrically arranged and fixedly connected with each other, wherein the first connection part is fixedly connected to the first rotating member, the second connection part is connected to the second rotating member in a torsion-proof manner, and the second connection part has a central hole for receiving the second rotating member. A cylindrical centering reference member is provided, the torque transmission member and the centering reference member are coaxially arranged by a centering tool during the process of assembling the torque transmission member, wherein the first connection part is provided with at least two through holes, and the centering tool passes through the through holes during a process of centering. A centering tool is provided for coaxially arranging the above-mentioned torque transmission member and a fixed cylindrical centering reference member, wherein the centering tool has at least two centering arms, wherein the centering arms are capable of passing through the through holes.

A mixing system includes a housing having a motor mount rotatably coupled thereto, the motor mount having a passage extending therethrough. A drive shaft is removably positioned within the passage of the motor mount. A cap includes a main body removably coupled to the motor mount and an actuator coupled to the main body so as to be pivotable between a first position and a second position with respect to the main body. The actuator producing a camming action when the actuator is pivoted such that when the actuator is in the first position, the actuator pushes the drive shaft against the motor mount so that the main body is locked to the motor mount and so that rotation of the motor mount causes rotation of the drive shaft and when the actuator is in the second position, the actuator is disengaged from the drive shaft and the cap is removable from the motor mount.

The present invention provides a rigid modular holding with axial and radial compensation for multiple and universal application of all machining processes, engineering, machine building, and construction fields where ever applicable for rotary and static systems. Design of modular holding includes male and female portions (401,301) of joining parts machined to the required shape and clearances to accommodate modular locking rigidly with face butting (407, 308). Radial and axial run out adjustments is controlled by the grub screws (307, 306) and run out compensation can be achieved within micron. An Area used for clamping and designed within the area of joining parts results reduction in material and processing cost. Since, the material is not protruding out from the surface of the joining parts, esthetically looks good and convenient for designing multiple applications as it is not possible at present.

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 torque transmitting assembly including a first drum having a plurality of teeth formed at an end thereof. A gear assembly axially aligns with the first drum and has a plurality of teeth intermeshing with the plurality of teeth of the drum. The gear assembly includes an annular gear and a plate axially aligning with the gear.
