REDUCTION GEAR APPARATUS

摘要

A reduction gear apparatus is provided to minimize the distortional stress generated from the axis by not delivering the unnecessary power to the axis of speed reduction gear. The first reduction gear(G1) comprises an input toothed gear(12) and an output toothed gear (14) which are arranged in the first axis(S1) and rotates at the same number of rotations. A bearing(18) is arranged between the shaft holes and the first axis of the first reduction gear. The input toothed gear of the first reduction gear is driven by a driving gear(DG). A transmission gear arranged in the secondary axis(S2) is driven by the output toothed gear of the first reduction gear. The first axis and the secondary axis are arranged in the gear-box(30). The second reduction gear is arranged in the secondary axis. The transmission gear is arranged in the first axis.
