An epicyclic gear train for a turbine engine includes a gutter with an annular channel. A rotating structure includes a ring gear that has an aperture that is axially aligned with the annular channel. Axially spaced apart walls extend radially outward relative to the rotating structure to define a passageway. The passageway is arranged radially between and axially aligned with the aperture and the annular channel. The walls are configured to inhibit an axial flow of an oil passing from the aperture toward the annular channel.

Disclosed herein are devices, systems, and methods relating to high-pressure fuel pump designs and features. A high-pressure fuel pump assembly includes a body, a camshaft, and an embossment. The body has a forward end and a rearward end opposite thereof and configured to couple to a low-pressure fuel pump. The camshaft is received and secured within a central bore of the body so as to be rotationally movable within the central bore. A coupler end of the camshaft is configured to couple to a drive shaft of the low-pressure fuel pump. The embossment includes at least one fastener boss configured to receive a fastener to couple the low-pressure fuel pump to the high-pressure fuel pump assembly. The embossment is formed at the rearward end of the body such that thermal stresses that cause geometrical deformations at the embossment are reduced through a range of engine temperature operating conditions.

A torque transmitting coupling assembly for a wind turbine configured to rotatably couple a first coupling part to a second coupling part, wherein the first coupling part and the second coupling part are configured to rotate about a longitudinal axis of the torque transmitting coupling assembly, wherein the torque transmitting coupling assembly includes a torque transmitting ring and a compression ring.

A disc assembly for an agricultural implement includes a mounting assembly having a housing and a rotatable shaft disposed within the housing. The rotatable shaft includes a recess extending along a portion of an axial extent of the rotatable shaft. The recess is formed by an inner surface of the rotatable shaft. The rotatable shaft also includes a first engagement feature formed on the inner surface and a key disposed about the recess. The key is configured to engage an opening of a disc blade to block rotation of the disc blade relative to the rotatable shaft. Furthermore, the disc assembly includes a fastener having a shaft configured to extend through the opening of the disc blade and to engage the recess of the rotatable shaft. The shaft has a second engagement feature configured to engage the first engagement feature to couple the disc blade to the rotatable shaft.

In a coupling structure for a propeller shaft and a propeller shaft, a propeller shaft-side adapter includes: a flange portion of the propeller shaft-side adapter extending in a radial direction relative to a rotation axis of a rotation shaft, and connected to a flange portion of a vehicle-side adapter; a center pin accommodating portion formed on the rotation axis, and into which a center pin provided to the vehicle-side adapter is inserted; and an inner peripheral portion formed between the flange portion of the propeller shaft-side adapter and the center pin accommodating portion in the radial direction relative to the rotation axis, which is opposed to the vehicle-side adapter in a direction of the rotation axis, and in which a distance from the rotation axis in the radial direction relative thereto decreases extending away from the flange portion of the vehicle-side adapter in the rotation axis direction.

A rotor assembly for a hybrid module includes a rotor carrier, a rotor segment, an end ring, a first spacer, a second spacer, and a compressed spring. The rotor carrier includes a first outer cylindrical surface and a radial surface, and the rotor segment is installed on the first outer cylindrical surface. The end ring is fixed to the rotor carrier and arranged for fixing to an engine flexplate. The first spacer is disposed axially between the rotor segment and the radial surface, and the second spacer is disposed axially between the rotor segment and the end ring. The compressed spring is disposed axially between the end ring and the second spacer to press the first spacer, the second spacer, and the rotor segment against the radial surface for frictional torque transmission between the rotor segment and the rotor carrier.

A power unit is configured for use as part of a concrete screed and includes a frame and a powered drive. The frame includes a drive housing.
