対偶に遊びのある機構の加減速時の特性

The dynamic characteristics of a crank-and-rocker mechanism whose crank rotates at the accelerated, uniform and decelerated motions have been theoretically and experimentally analyzed with consideration of bearing clearances. Moreover, for a crank-and-rocker mechanism obtained by a dynamic design method which makes it possible to determine directly the optimum shapes of the moving links to prevent separations and collisions between pairing elements in the case where the crank rotates at a constant-speed, the influences of bearing clearances and the non-uniform motion of the crank upon the relative motions between pairing elements and the input torque have been discussed together with experiments, comparing with the dynamic characteristics of the traditional mechanism whose shape of the coupler is a rectangle.
