Transmission mechanism capable of suppressing vibrational noise |
摘要 |
A transmission mechanism is capable of effectively attenuating vibrations generated thereby during operation by converting vibrations into heat energy. The base plate is provided with a plurality of flexible connecting ribs and a plurality of substantially sectorial openings formed alternately around a motor base part for holding a motor and bearing parts for supporting the shafts of the gears. Each of the gears has a rim provided on its outer circumference with teeth, a hub and flexible arms connecting the rim to the hub. Vibrations generated by the motor and those generated by the gears strain the flexible connecting ribs of the base plate and the flexible arms of the gears, the strains of the flexible connecting ribs and the flexible arms are converted into heat energy in the end and the heat energy dissipates, so that the variations are attenuated and noise attributable to the vibrations is suppressed.
