Abstract
For sine movable tooth drive, the movable tooth number must be increased to obtain large speed ratio of the drive which increases largely radial size of the drive. Here, a two-step sine movable too...
Highlights
Movable tooth drives have a lot of advantages such as high operating efficiency, simple structure, and small size
In 2013, Nam et al.[10] designed and manufactured one thin plate-type speed reducer using ball teeth for robots, and the thin platetype speed reducer imposed less compressive stress on the tooth profile and the balls, which greatly increased the facility of the robot
Results show that the output torque of the two-step sine movable tooth drive is much larger than that of the single-step sine movable tooth drive
Summary
Movable tooth drives have a lot of advantages such as high operating efficiency, simple structure, and small size. Among above-mentioned movable tooth drives, the sine movable tooth drive has the smallest radial size and is suitable for oil drilling machine and robot arm and so on.[5,6] for the sine movable tooth drive, the movable tooth number must be increased to obtain a large speed ratio of the drive. It increases largely radial size of the drive
