摘要： A power take off unit includes an input gear, an output gear, and an intermediary gear that cooperate to transfer power from a rotational power source to an operating target. The power take off unit has a control module that biases the intermediary gear relative to the input gear and the output gear to reduce gear rattle vibrations associated with intermeshed tooth looseness.

摘要： Systems and methods are described for shoulders that can be implemented on shafts in gear systems, such as a drive train. The shoulders, in combination with other components like bearings, or nuts, can help restrict movement of the shaft within the drive train. Use of the shoulders in various embodiments can avoid the need for grind reliefs in corners. Grind reliefs can help in prior art systems where machining or grinding is used at surfaces where raceways of bearings border shoulders that are integrated with the shaft. Grind reliefs create tight spaces where edge breaks are difficult to create. Press-fit shoulders, such as described herein, allow machining and edge break creation on the shaft prior to installation of the shoulder.

摘要： A cam-locking system for use with a retractable driveshaft that includes a housing, a cam carrier located at least partially in the housing, and a cam rotatably coupled to the cam carrier. Translation of the cam carrier along a central axis allows the cam to rotate into cooperative engagement with a catch recess on an interior surface of the housing, preventing the cam carrier from translating backwards, and thereby maintaining the retractable driveshaft in an engaged position. Further advancement of the cam carrier allows that cam to rotate into and unlocking gap in the interior surface of the housing, which enables the cam carrier to translate backwards along the central axis below the locked position, thereby disengaging the retractable driveshaft.

摘要： A gear unit includes a shaft, rotatably mounted via a first bearing, a housing part, and a cover connected to the housing part. The shaft has a threaded region onto which a nut is screwed, and a spacing sleeve and a disk are arranged between the nut and an inner ring of the spacing sleeve. The greatest outer diameter of the disk is greater than the greatest outer diameter of the spacing sleeve; the greatest radial distance of the disk relative to the rotational axis of the shaft is greater than the greatest radial distance of the spacing sleeve relative to the rotational axis of the shaft; and/or the radial spacing region covered by the disk and relative to the rotational axis of the shaft contains the radial spacing region covered by the spacing sleeve.

摘要： A power transmission device according to one aspect of the disclosure includes a first gear, a base member, a second gear, a support block, a position adjusting unit, and a fixing unit. The base member rotatably supports the first gear. The second gear engages with the first gear so as to be able to transmit power. The support block rotatably supports the second gear. The position adjusting unit adjusts relative positions of the support block and the base member in a direction in which an engagement depth between the second gear and the first gear varies. The fixing unit fixes the relative positions of the support block and the base member.

摘要： A transmission with alternating rotary disks is presented. The transmission with alternating rotary disks contains a plurality of first rotary disk assemblies, a plurality of second rotary disk assemblies, a drive shaft, and a gearbox shell. The plurality of first rotary disk assemblies is rotatably connected to the plurality of second rotary disk assemblies, where the plurality of first rotary disk assemblies and the second plurality of disk assemblies are arranged in a specified pattern. The first rotary disk assembly contains a first rotary element that rotates in one direction when the drive shaft is subjected to torque. The second rotary disk assembly contains a second rotary element that rotates in the opposite direction, relative to the first rotary element rotation.
