Patent ID: 7280947

Claim:
A gear driving system designing system, comprising: a computer comprising: one or more processors; a memory storing a program logic; and a display terminal; and a manufacturing unit connected to the computer; the program logic comprising: a setting means for setting one or more gear characteristic values for the gear driving system, the gear characteristic values indicating characteristics of a final gear and a driving gear in the gear driving system for simulation of oscillations in the final gear of the gear driving system; a calculating means for simulating oscillations in the final gear of the gear driving system, based on the one or more gear characteristic values set by the setting means; a judging means for judging whether or not the simulated oscillations in the final gear determined by the calculating means are within acceptable ranges; a setting changing means for changing the one or more gear characteristic values set by the setting means, when the judging means judges that the simulated oscillations in the final gear do not fall within the acceptable ranges; means for causing said setting changing means, said calculating means, and said judging means to repeat their respective functions until the simulated oscillations in the final gear are judged to fall within the acceptable ranges by the judging means; and wherein when said judging means judges that the simulated oscillations in the final gear are within the acceptable ranges, the one or more gear characteristic values corresponding to the simulated oscillations are output from the designing system to a manufacturing unit for manufacturing the gear driving system or to the display terminal.
