| Research Abstract |
The self-locking property of a belt wrapped two or three times around an axis was clarified theoretically and was confirmed experimentally. By utilizing this property, a simple structured clutch was developed, which can transmit torque even in an off-centered condition. The relation between the off-centered distance and the corresponding variation of angular velocity was derived from geometrical viewpoint. The theoretical relation was confirmed by means of experiments. A tricycle was developed by using the clutch mentioned above. Experiments confirmed that the clutch works properly and that the tricycle runs smoothly without any vibration.
