Abstract: In one example, a portion of a transmission includes a first shaft, and a first gear cluster that includes a first group of coaxial nested gears that are movable in an axial direction relative to each other. The first group of coaxial nested gears includes a first gear that is fixed to the first shaft. The portion of a transmission further includes a self-centering mechanism that accommodates tolerance gaps between two successive gears of the first gear cluster.

Abstract: A moon gear assembly is provided that includes a moon arm assembly having a driving moon gear. A pivot pin is connected to the moon arm assembly, and an adjustment arm is connected to the moon arm assembly. The moon arm assembly may also include a body that defines a chamber, a worm gear disposed in the chamber and arranged to interact with the driving moon gear, and a motor disposed in the chamber and couple to the worm gear.

Abstract: In one example, a transmission is provided that includes a sheave of selectively variable configuration, a driven member configured to engage the sheave, and a plurality of drive members configured for radial movement to selectively engage the driven member. The transmission may be operable in one or more of the following modes: traction mode, integer mode, IN mode, and infinite mode.

Abstract: The present invention relates to transmission systems and changing gear ratios within power transmission systems. In particular, the present invention relates to a positive displacement variable speed transmission. The transmission includes one or more drive gears which orbit, rotate, and which translate radially to change the size of the orbital path. The change in the orbital path increases or decreases the linear velocity of the drive gears which engage one or more driven gears and transfer the changed linear velocity in the form of a gear ratio change. The driven gears are also radially movable and movement of the driven gears is synchronized with the radial movement of the drive gears to maintain substantially constant engagement between gear ratios change. Thus, as the drive and driven gears can slide or step radially to any location within a range of positions, gear ratio changes can be made in very small increments.

Abstract: Transmission systems, assemblies, and components are described. In particular, aspects of the present disclosure relate to an infinitely variable transmission that maintains constant tooth engagement during changes in gear ratio. In one aspect, a transmission includes an axially movable sheave coupled to a chain. The sheave rotates around a drive axis. At least partially within the sheave is a set of moon gears. The moon gears orbit around the drive axis and are rotatable around respective internal axis. As the sheave moves axially, the chain and the set of moon gears move radially to define different gear ratios, with the gear ratios being changeable in infinitely small increments. A synchronization system moves the set of moon gears radially to correspond to the axial position of the sheave. A correction system optionally controls rotation of the moon gears to rotate teeth of the moon gears into alignment with the chain.

Abstract: Disclosed are systems, assemblies, and components that relate to power transfer. In particular, the disclosed systems includes a transmission that offers variable speeds and changes between different gear ratios while maintaining constant engagement. Constant engagement may be maintained by tooth-to-tooth contact to be scalable for a variety of applications. An example system includes a phase shifting mechanism. The phase shifting mechanism may include an eccentric gear that provides an oscillating output. The oscillating output creates an overall gear ratio change that slides between gear ratios, thereby allowing changes to occur in small, and possibly infinitely small increments. According to one example, an eccentric gear has a changing base radius and includes a tooth with a hybrid profile that has a base the width of an initial profile, and a width at a top of the tooth that is that of a final profile.

Abstract: A transmission apparatus for changing the speed of a driven member relative to the speed of a driving member for transmitting effectively continuous torque transfer between the members. The apparatus includes cam gears driven by a driving member, driven gears in continuous engagement with the cam gears, and a driven member which journals the driven gears for rotation. One section of the driving member is hollow and has a plurality of radially extending apertures, each containing a reciprocating detent for engaging an inner cam surface of a corresponding cam gear. A shift member mounts within a bore of the driving member and rotates about the longitudinal axis of the driving member to cause the detents to reciprocate between a cam gear engaged position and a disengaged position.

Abstract: A transmission apparatus for changing the speed of a driven member relative to the speed of a driving member while providing continuous torque to the driven member. The apparatus includes reducing gears driven by a driving member, annular cam gears in continuous engagement with the reducing gears, and a rotatably mounted hollow drum having a plurality of radially extending apertures each containing a detent arranged for reciprocating movement for engaging an inner cam surface of a corresponding cam gear mounted for rotation about an outer drum surface. A cam member mounted within the drum for reciprocal movement along the drum axis has an outer cam surface for respectively reciprocating the detents between a cam gear engaging position and a disengaged position. The inner cam surface of the cam gears have peak sections and valley sections, and axial movement of the cam member to initiate a gear shift is timed relative to the positions of the peak sections and valley sections on adjacent cam gears.
