Novel coupling applicable in off-centered condition

A novel coupling was devised by utilizing the self-locking property of a belt. The torque is transmitted through a flexible belt. The belt length between the power disk and the driven shaft varies with a rotation of shaft in an off-centered condition. It causes an angular velocity fluctuation when t...
