A GEAR DRIVE APPARATUS THAT DRIVE TWO OUTPUT-SHAFTS SEQUENTIALLY BY ONE INPUT AXLE

摘要

PURPOSE: A biaxial sequential gear driving device is provided to sequentially drive two output rotary power shafts with one input rotary power shaft by enabling stop or free rotation of components of a planetary gear train. CONSTITUTION: A planetary carrier member (1120) prepares a carrier driving member and supports a free gear. A set of planetary gear modules (1100) are engaged by being connected to an input rotary power shaft or by being consisting of a sun gear having a sun gear driving member driving an output rotary power shaft. A brake module (1200) selectively stops or freely rotates a component of any one combination selected from a ring gear and the planetary carrier member, or the planetary carrier member and the sun gear, or the ring gear and the sun gear of the planetary gear module. A support module (1300) supports the planetary gear module and the brake module.
