TIMING BELT-DRIVEN MECHANISM

摘要

PROBLEM TO BE SOLVED: To loosen a belt or to cause gear skip by adjusting the load of a predetermined belt transmission with a parallel plate spring so that a distance between rotary shafts between pulleys of a timing belt is shortened in a pulley rotational direction according to the belt tension.;SOLUTION: In the timing belt-driven mechanism, torque is transmitted between two pulleys each having a rotary shaft parallel to each other, There is provided a parallel plate spring deformable in a direction in which the distance between the shafts the pulleys is changed by receiving the tension of the timing belt. One side end of the parallel plate spring is brought to match with the position of the timing belt in the direction along the rotary shaft of the pulley, and the other side end is fixed to a substrate member to support the rotary shaft of the pulley.;COPYRIGHT: (C)2009,JPO&INPIT
