Two conditions are required to bring about self-locking. One is smaller coefficient of beltbelt friction than that of belt-axis friction. The other is larger wrap angle than the critical wrap angle. Utilizing the self-locking property of belt a novel one-way clutch was developed. The problem of this clutch is how to get the smaller and stable coefficient of beltbelt friction for long time use. Friction of a flexible element wrapped around a generalized profile was studied. However the friction of twisted flexible element in a thread rope and wire has not been clarified yet. Further research is required. 7. References Hashimoto H. 2006 . Tribology Morikita publishing ISBN 4-627-66591-1 Tokyo Imado K. 2007 .
