概要

This paper discusses the study of a traction drive transmission that uses a wedge action by creating input and output axes that are eccentric. Contact force is acquired in proportion to transmitted torque. Although, this eccentric structure is simple in design, it creates a different traction coefficient at each traction contact point. In order to design a structure that does not incur gross slippage, we need to examine the traction contact point where the traction coefficient is at its highest value. This paper further reveals the traction contact point value at its highest traction coefficient. This is accomplished by analyzing numerical expressions representing the balance of force equation from the viewpoint that a traction coefficient is automatically adjusted. Finally, this paper presents an example of an actual design and test results that show basic characteristics, efficiency, and wedge action in transmitting power. Our test results demonstrate that the traction drive transmission developed through our research achieves high efficiency through wedge action and realizes sufficient contact force in proportion to transmitted torque.
