Title:
ハイブリッド減速機およびモータ付きハイブリッド減速機
Document Type and Number:
Japanese Patent JP7448111
Kind Code:
B2
Abstract:
To provide a structure capable of entirely downsizing a device.SOLUTION: A hybrid reduction gear 1 comprises a first reduction mechanism 40 and a second reduction mechanism 50. A planetary friction speed reduction mechanism is used for the first reduction mechanism. A plurality of planetary rollers 42 of the first reduction mechanism revolve around a central axis 90 while rotating by receiving power from a sun roller while being in contact with both a sun roller 41 and a ring. Each of the plurality of planetary rollers is supported in a rotatable manner by a first planetary shaft 43. A wave gear reduction mechanism which transmits power while gear-changing rotational movements by utilizing a differential between a flexible outer tooth gear 52 and a flexible inner tooth gear 53 which are meshed with a relay member which is rotated together with a carrier 511 is used as the second reduction mechanism. A plurality of first planetary shafts of the first reduction mechanism are fixed radially outside of the central axis to the carrier.SELECTED DRAWING: Figure 1
