<p>PROBLEM TO BE SOLVED: To improve a lifetime and reduce loss torque.SOLUTION: A wave gear device 150 includes: two rigid inner gears 20 and 30; a flexible outer gear 40 disposed inside the rigid inner gears 20 and 30; and a wave generator 50 disposed inside the flexible outer gear 40. The wave gear device 150 has an input rotary shaft 51 disposed inside the rigid inner gears 20 and 30 coaxially with the rigid inner gears 20 and 30. Further, the wave gear device 150 has a disk group 601 comprising two disks 61 and 62 disposed corresponding to the rigid inner g ear 20 and mounted eccentrically on the input rotary shaft 51 in different directions from each other. Furthermore, the wave gear device 150 has a disk group 602 comprising two disks 63 and 64 arranged corresponding to the rigid inner gear 30 and mounted eccentrically on the input rotary shaft 51 in different directions from each other.</p> |
