REDUCTION GEAR APPARATUS

摘要

A reducer is provided to rotate the reduction gear about the axis of speed reduction gear by mounting the bearing around the axis hole to be rotatable. A bearing(18) is pivotally arranged between the shaft holes and principal axis(S1) of the first reduction gear(G1). The first reduction gear is relatively rotated against the principal axis. An input toothed gear(12) of the first reduction gear goes in gear with a driving gear(DG) of the motor. An output pulley(14) of the first reduction gear goes in gear with a transmission gear(TG2) mounted on the secondary axis(S2). The principal axis and the secondary axis are pivotally arranged in the gear-box(30). The input pulley and output pulley of the first reduction gear are rotated with the same number of rotation.
