Eccentric-differential-reduction gear for use in e.g. wind mill, has auxiliary crank shaft arranged within ring and partially affiliates with output cam members that are coupled to pivotal gear wheel during rotation of gear wheel

摘要

The gear has main crank shafts (13) arranged on spur gears (12), and an auxiliary crank shaft (18) rotatably clamped relative to an output shaft (14). The auxiliary crank shaft includes output cam members (18a, 18b) that are eccentrically arranged at a central line (Z2). The main crank shafts are arranged in such a manner that the central line perpendicularly intersects with a ring. The auxiliary crank shaft is arranged within the ring and partially affiliates with the output cam members that are coupled to a pivotal gear wheel (15) during the rotation of the gear wheel.
