A splined coupling comprises a radially inner shaft and a radially outer shaft having a cavity for receiving the inner shaft. First splines are provided on a radially outwardly facing surface of the inner shaft. Second splines are provided on a radially inwardly facing surface of the cavity of the outer shaft. The first splines are slidably engaged with the second splines. At least one biasing element, for example a diaphragm is arranged to act between the radially inner and radially outer shafts for locating the first splines in a desired axial position relative to the second splines and to provide a biasing force resisting the axial movement of the first splines relative to the second splines upon relative axial movement of the inner and outer shafts.

A motor drive unit, in which an output end of a motor drive system using an electric motor as a power source and a rotator rotatably supported by a bearing unit are arranged side by side in an axial direction, and the output end of the motor drive system and the rotator are drivingly coupled in a relatively displaceable manner by a coupling member in which a plurality of couplers spaced apart in an axial direction are set. The bearing unit of the rotator is arranged such that a center of displacement of the rotator defined by the bearing unit is located between an arbitrary pair of couplers among the couplers.

A coupling assembly having a first member drivingly connected to a second member via one or more third members. A first shaft is drivingly connected to the first member and a second shaft is drivingly connected to the second member. The second member includes a flange portion having one or more seating portions on a first end portion of the flange. Additionally, the flange has one or more flange portion attachment apertures extending from the seating portions to a second end portion of the flange. An increased diameter portion of the second shaft has one or more increased diameter portion apertures extending from a first end portion to a second end portion. The flange portion apertures and the increased diameter portion apertures have a center-line with an angle from an axial center-line of the assembly. Additionally, the seating portions have an angle relative to a radial center-line of the assembly.

A turbocompound unit for converting energy of an exhaust gas from an internal combustion engine to torque increase of a crankshaft of the internal combustion engine includes a turbine arrangement and an arrangement configured to operatively connecting the turbine arrangement to the crankshaft is a hydrodynamic coupling and freewheeling arrangement. The turbocompound unit further includes a brake arrangement, wherein the brake arrangement and the freewheeling arrangement are located on an opposite side of the hydrodynamic coupling in relation to the turbine arrangement.

A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

A coupling assembly having an overrun mode and a channeled locking member are provided. The locking member has a ramped, open channel extending through a nose and main body of the locking member to an upper face of the main body. The locking member is movable between first and second positions. The first position is a coupling position and the second position is an uncoupling position. Pressurized fluid directed to a bottom of the channel urges the locking member towards the second position upon rotation of a first member of the assembly in a first direction relative to a second member of the assembly above a predetermined RPM to prevent abutting engagement of the locking member with a shoulder of the first member in the overrun mode.

The drive shaft (1) comprises end universal joints (5, 7) with accident-preventing end protections (19). Each accident-preventing end protection comprises a lubricant reservoir, delimited radially inwardly by a sleeve (63) of an inner fork (23) of the respective universal joint (5; 7) and radially outwardly by a rigid annular structure of the accident-preventing end protection.

A selectable one-way clutch adapted to prevent an undesirable engagement is provided. The selectable one-way clutch comprises a drag increasing device that increases a drag of oil acting between the pocket plate and the selector plate against a force rotating the selector plate in a direction to bring the selectable one-way clutch into the engagement mode.

A synchronizing ring for a synchronizer having an inner ring. The synchronizing ring is designed to be arranged outside of and to abut against the inner ring for achieving friction between an outer surface of the inner ring and an inner surface of the synchronizing ring during synchronization. The synchronizing ring has a plurality of through holes extending from the inner surface to an outer surface of the synchronizing ring for evacuation of oil from the interface between the inner ring and the synchronizing ring.

A dual clutch unit includes an outer disk carrier rotationally driven about a rotation axis, first and second inner disk carriers, first and second disk packs for torque transmission between the outer disk carrier and the respective inner disk carrier, wherein the first and second inner disk carriers are arranged rotatably relative to each other about the rotation axis, a central oil supply to supply the first and second disk packs with coolant, a first distributor channel being formed in the first inner disk carrier and comprising a feed opening through which the first distributor channel is fluidly connected to the central oil supply, a second distributor channel being formed in the second inner disk carrier and being fluidly connected to the central oil supply via the first distributor channel, and drain channels being formed in the inner disk carriers to conduct the coolant into the disk packs.
