OPTIMIZED TORQUE, OPTIMIZED ROTATIONAL SPEED, LONG STROKE CRANK, VARIABLE SPEED CRANK

摘要

PROBLEM TO BE SOLVED: To solve the problems that a crank converting reciprocating motion into rotating motion is always incapable of optimizing a torque at initial motion, center, and turnover at terminal, averaging and uniforming speed, and a gear change is also made with another mechanism.;SOLUTION: Input and output cranks 23, 24 are disposed on a shift lever 21 in a way that a fulcrum is arbitrarily movable. Rotational speed is also output by link chain movement continuously from reduction to enlargement.;COPYRIGHT: (C)2010,JPO&INPIT
