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.

A shaft-hub connection with a shaft that includes a section with external splines, and a hub that includes internal. The hub with its internal splines is assembled in a positively joined manner with play on the section of the shaft including the external splines. The shaft in the section includes the external splines has a recess regularly inside of the external splines, in which a clamping body is inserted neutralizing the play between shaft and hub.

A modular motor assembly structure is disclosed and configured to couple with a drive shaft of an application device. The drive shaft includes a receiving slot. The modular motor assembly includes a main body and a combination key. The main body includes a shaft hole and a key groove. The shaft hole includes an opening and a central axis. The key groove is disposed on a side wall around the shaft hole and parallel to a central axis of the shaft hole. The combination key has a front end and a rear end. When one end of the drive shaft is inserted into the shaft hole along the central axis of the shaft hole, the combination key is at least partially accommodated in the receiving slot, and the front end faces the key groove. The combination key has a continuously increasing thickness from the front end to the rear end.

A method for manufacturing an assembled camshaft for valve-controlled internal combustion engines, in which at least one cam disc with a base circle region and cam region is machined on the running surface and has a cam-disc recess, includes shrinking the cam disc onto a corresponding shaft designed with a defined dimensional overlap by cooling the shaft and heating the cam disc. Temporally before being shrunk onto the shaft, the at least one cam disc is clamped by a clamping device such that a tension force acts on the recess wall region, which defines the cam-disc recess, the tension force corresponding to a predetermined extent to the state of stresses and/or deformation state of the recess wall region after the operation of shrinking the cam disc onto the corresponding shaft. The running-surface machining of the at least one cam disc takes place when the cam disc is clamped by the clamping device.

A tripot housing and method of manufacture thereof is provided. The tripot housing includes a housing body extending along an axis between a first end having an end wall and an open second end. A drive shaft extends from the end wall along the axis away from the second end. The housing body has an outer surface and an inner surface. The inner surface defines a guide channel that extends between the first end and the second end. The outer surface has a first region extending axially along a direction from the first end toward the second end to a shoulder that extends radially outwardly from the first region. The outer surface has a second region extending axially from the shoulder toward the second end. A ring has an inner surface disposed in an interference fit on first region and an outer surface extending radially outwardly from the second region.

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 stiff key provides rigid coupling between a pair of shafts, such as a motor shaft and a rotary position sensor. The key may have a main body and a protrusion from the main body, such as from a middle portion of the main body. One of the protrusion or the main body may engage one part of one of the shafts being coupled together, and the other of the protrusion or the main body may engage a part of the other of the shafts. For example the protrusion may be in a keyway of one shaft and the main body may engage a recess or flat of the other shaft. The key and the coupling may be used in applications where space is at a premium, for example in a missile.

A drive shaft coupling for connecting a rotating tube cleaning shaft to a tube cleaning machine wherein high pressure fluid is pumped through the coupling, wherein the coupling is sealed to contain the high pressure fluid, and wherein a machine driven rotary flexible shaft passes through the coupling.
