A vehicle driveline component having a housing with a lube feed ramp between a bearing bore and a surface in which a first end of a lubricant channel is formed. The bearing supports a pinion for rotation about a first axis. The surface is transverse to the bearing bore. The lube feed ramp is defined by a warped planar surface that provides a transverse transformation between the bearing bore and the surface that is transverse to the bearing bore. The lube feed ramp is configured to direct a portion of a lubricant exiting the bearing into the first end of the lubrication channel.

An gear case assembly for a watercraft propulsion system has a gear case housing, a driveshaft with a partially threaded bore defined in an end thereof, and a propeller shaft. The propeller shaft and the driveshaft are angled relative to each other. A bevel gear is mounted to the propeller shaft. A pinion mounted to the end of the driveshaft. The pinion meshes with the bevel gear. The pinion defines a central aperture. A fastener is disposed at least in part in the central aperture of the pinion. The fastener fastens the pinion to the end of the driveshaft. The fastener has a head and a shank. The shank is at least partially threaded. The shank extends into the bore of the driveshaft. An outboard motor having the gear case assembly is also disclosed.

The invention relates to a drive device for activating a rotary slide for a fluid system of an at least in part electrically operated motor vehicle. The drive device comprises an electric motor having a motor output shaft, a rotary slide output shaft configured for activating a rotary slide, wherein the rotary slide output shaft is aligned so as to be orthogonal to the motor output shaft, and a magnet is disposed on an end region of the rotary slide output shaft, and a sensor unit which is configured for detecting a rotary position of the magnet and thus of the rotary slide output shaft.

A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.
