Motor interface for parallel drive shafts within an independently rotating member

Abstract: Mechanisms, assemblies, systems, tools, and methods incorporating the use of an offset drive shaft within an independently rotating member are provided. An example mechanism includes a base and a main shaft mounted to rotate relative to the base, a first drive shaft mounted inside the main shaft, and a first drive feature engaged with the first drive shaft. The main shaft includes a proximal end, a distal end, and a main shaft rotational axis defined therebetween. The first drive shaft is offset from the main shaft rotational axis. A first drive feature rotational axis is defined for the first drive feature and is fixed relative to the base as the main shaft rotates. The first drive feature rotates the first drive shaft.

Marine transmission with a cone clutch used for direct transfer of torque

Abstract: A transmission for a marine propulsion system uses a cone clutch in such a way that, when in a forward gear position, torque is transmitted from an input shaft, or driving shaft, to an output shaft, or driven shaft, solely through the cone clutch. When in forward gear position, driving torque between the driving and driven shafts is not transmitted through any gear teeth. When in reverse gear position, torque is transmitted through an assembly of the bevel gears.

Tool drive system

Abstract: A tool drive system for transferring rotational power from a rotational tool, such as a drill or ratchet, to at least one input drive shaft which then transfers the power to at least one output drive shaft. The angle of at least one input drive shaft being adjustable relative to at least one output shaft. The tool drive system comprises a round housing with an angle adjuster attached to the input shaft that assists in adjusting and locking the angle of the input shaft relative to the output shaft in an almost circular span. The input and output shafts may be positioned in a user-selected gear ratio from the input to output shafts or vice versa.

Wind turbine and a shaft for a wind turbine

Abstract: A drive shaft for a wind turbine is shaped so as to allow for increased bending of the shaft, while being suitable for transferring torque in a wind turbine system An example of such a shaping is a drive shaft having a helical rib defined on the surface of the shaft A wind turbine incorporating such a shaft, and a method of manufacture of such a shaft are also described

Coupling system for a planetary gear train

Abstract: A coupling system including a sun gear coupling (32) and a ring gear coupling (158) for connecting the sun gear (36) and the ring gear housing (50) of a planetary gear train (26) to an external shaft (24) and an external mechanical ground (56) respectively are each characterized by undulant cross sections for accommodating parallel and angular misalignments. A ring gear deflection limiter (158), antirotation spline (190) and vibration damper are also included for enhanced operation.
