The Gear mechanism with passive rollers: The input mechanism to drive the omnidirectional Gear and worm Gearing
2013 IEEE International Conference on Robotics and Automation, 2013Co-Authors: Riichiro Tadakuma, Kenjiro Tadakuma, Kyohei Ioka, Yuichi Tsumaki, Mitsuru Higashimori, Minoru Takagi, Shotaro Onishi, Gaku Matsui, Makoto KanekoAbstract:We have been studying an omnidirectional Driving Gear mechanism that can generate thrusting force in an arbitrary direction on one surface, which may be flat or curved. This omnidirectional Gear is driven by spur Gears that are perpendicular. When one spur Gear rotates to drive the omnidirectional Gear, the other slides between the teeth of the omnidirectional Gear and vice versa. In this paper, we introduce Gears with passive rollers to reduce the frictional resistance with a mechanism including smooth rolling motion of conical or flat passive rollers, which can boost the power transmission efficiency of the omnidirectional Driving Gear system. We also confirmed another useful function of this Gear with passive rollers as a worm wheel to transmit power from a worm Gear with higher energy efficiency than an ordinary worm wheel.

IROS - Omnidirectional Driving Gears and their input mechanism with passive rollers
2012 IEEE RSJ International Conference on Intelligent Robots and Systems, 2012Co-Authors: Kenjiro Tadakuma, Riichiro Tadakuma, Kyohei Ioka, Takeshi Kudo, Yuichi Tsumaki, Mitsuru Higashimori, Minoru Takagi, Makoto KanekoAbstract:As ordinary dual-axis Driving mechanisms in X-Y directions, for example, commercially available X-Y stages with ball screws are familiar. However, such Driving mechanisms have two stages, namely both upper and lower linear actuators, the latter of which must generate sufficient thrust to carry large weights, including that of the upper actuator mechanism, which has hampered efforts to achieve suitably fast and smooth Driving motion due to the inertial force effect. It is also difficult to achieve a small and slimline Driving mechanism with such overlapping two-stage structure. In these ordinary two-stage Driving mechanisms, the motion of the X-Y stage can be disturbed by the wires of the upper actuator. In this research, we have considered the abovementioned problems, and propose a new omnidirectional Driving Gear mechanism that enhances its Driving area from the normal X-Y plane to convex and concave curved surfaces respectively, and even various combinations of both. The smoothness of basic omnidirectional motion and effectiveness of the Driving method of this proposed omnidirectional Driving Gear mechanism have been confirmed with several experiments involving our setups.
