Coaxial reducing gear for e.g. rotating machine, has multiple gears with uniformly variable radii, where specific reduction ratio exists for gears at end of starting phase in direct drive without internal movement

摘要

The gear has multiple gears (3) for the starting phase of a rotating machine and having uniformly variable radii. The reduction ratio of the gears at the end of the starting phase is 1:1 in direct drive without internal movement. The gears include two pinions (1, 2) having common axes with the gears. The reduction ratio of the pinions is the same as the ratio between the extremes of the radii of the gears.
