GEARLESS TRANSMISSION ABSTRACT A gearless transmission provides synchronous back-lash-free, reversible power transfer between three or more parallel shafts having non-aligned rotational axes. A preferred embodiment for use with a hoist drive incorporates four such working shafts, one of which is driven by a drive motor, the transmission incorporating a synchronizing plate, each shaft having a cable winding drum mounted thereon. The transmission includes a cable level wind guide, permitting a side take-off, such that, in use as a hoisting mechanism, the hoist drive may be located at any preferred location. This in turn enables the provision of a substantially vibration free elevator service, and the capability of avoiding the requirement for a penthouse power room.
