Coaxial reducer starting aid with growing relationship to direct coupling.

摘要

mechanical reducer coaxial with continuously decreasing reduction using a plurality of gears (3, 4) with variable radii for starting phase rotating machine, and said gears (3, 4) are uniformly varying radii, characterized in that the reduction ratio at the end of the start phase is 1: 1 in direct coupling and that the reducing then no longer comprises any part in internal motion.
