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 valve assembly of a faucet includes a valve body, a valve cartridge received within the valve body and including a valve stem defining a longitudinal axis, and a handle operably coupled to the valve stem of the valve cartridge. Illustratively, a spring biases splines of a valve stem adapter downwardly into engagement with splines of the valve stem.

A shaft assembly for an aircraft engine includes a first shaft coupled to a second shaft with a splined coupling made of an electrically-insulating material. The first and second shafts and the splined coupling are rotatable about an axis. A positioning device is mounted to the splined coupling and to the first shaft about the axis. The positioning device is displaceable along the axis relative to the first shaft to vary an axial position of the splined coupling.

The present invention relates to a centrifugal pellet dryer comprising a housing accommodating a rotor surrounded by a screen, wherein said screen includes at least one porous screen member and is supported by a screen support holding the screen relative to the housing. To avoid vibrations and noise, the centrifugal pellet dryer has the screen supported against the housing by a screen support which includes at least one damper for dampening vibrations of the screen and/or isolating screen vibrations from the housing.

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 trunnion and socket assembly is provided. The trunnion and socket assembly includes a trunnion, a socket, and a retention assembly. The trunnion includes a first portion and a second portion, the second portion defining an outer diameter. The retention assembly includes at least two cap elements and a ring member. The cap elements are coupled in an abutting relationship with a first surface of the socket. The cap elements have a second surface and a third surface. The ring member is adapted to be coupled in an abutting relationship with the third surface of each of the cap elements. The ring member has a fourth surface and a fifth surface. The ring member defines an inner diameter that is greater than the outer diameter of the second portion of the trunnion.

Melt pumps for pressing synthetic melt through a tool are disclosed. An example melt pump for building up pressure for pressing synthetic melt through a tool includes a compressor with two worm conveyors disposed in a housing, a transmission by means of which the worm conveyors are synchronously drivable, and a drive, where the transmission is disposed between the drive and the compressor. In the example melt pump, each worm conveyor in the transmission has an output shaft, and each worm conveyor is coupled to the corresponding output shaft by a coupling. In the example melt pump, the coupling comprises an output gear provided on the output shaft, and a drive gear provided on the worm conveyor and a coupling sleeve gripping the output gear and the drive gear, where the drive gear and the output gear have a different number of teeth.
