Title:
REDUCTION GEAR
Document Type and Number:
Japanese Patent JP2012219865
Kind Code:
A
Abstract:

To provide a reduction gear using driving forces having different characteristics, in aspects depending on various intended use, with relatively simple mechanism, by receiving and outputting forces from a plurality of driving sources with different characteristics through a speed reduction part at least partially in common.

The reduction gear includes: a first input part 2 receiving a driving force from a first driving source 1; the speed reduction parts 3, 4, 5 decelerating the input driving force through a planetary gear reduction mechanism; an output part 6 outputting the decelerated driving force; and a second input part 3 disposed to a part of the speed reduction part and receiving a driving force from a second driving force 9. When the second input part 3 is about to move on receiving the force from the second driving source 9, movement of a first input part 2 is automatically stopped, or the first input part 2 is automatically moved so as to diminish movement of the output part 6 along with the movement of the second input part 3.
