METHOD AND DEVICE FOR CALCULATING APPROXIMATE VALUE OF OVERALL LENGTH OF TIMING BELT, METHOD AND DEVICE FOR PLOTTING THREE-DIMENSIONAL IMAGE OF TIMING BELT, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a calculating method for an approximate value of the overall length of a timing belt extended among pulley groups irrelevantly to the kind of the timing belt.;SOLUTION: The approximate value of the overall length of the timing belt 16 is calculated (summing process) by adding up the total (common tangent totalizing process) of the lengths of all common tangents MN, OP, QR, ST, and UV where the timing belt comes into contact with couples of pulley groups which are adjacent along the path of the timing belt and the total (connection line totalizing process) of the lengths of connection lines NO, PQ, RS, TU, and VM connecting the respective common tangents along the path.;COPYRIGHT: (C)2002,JPO
