Hollow shaft epicyclic translative drive with centrally positioned transmittance and integrated utility apparatus

摘要

A drive is disclosed that is useful with a variety of apparatus for either multiplying torque or increasing rotational speed. The drive includes a supported inner shaft having a sun gear at one end, the inner shaft receivable through a hollow outer coaxial shaft having an engageable transmittance (a spur gear, for example) intermediate first and second opposite ends thereof. A planetary gear set platform is located at one end of the outer shaft, planet gears rotatably mounted thereabout in engagement with the sun gear received through the platform for rotation in a stationary ring gear. A right angle translate gear is affixed to the inner shaft adjacent an end thereof opposite the sun gear, a rotational source engagable at one of the translate gear and the transmittance and a utility output engagable at the other.
