ABSTRACT:
A gear mechanism provides for intermittent drive operation with precision stop location of angular position of one (driven) gear driven by another (drive) gear which is accomplished by increasing the precision of the distance maintained between the rotational centers of the gears so that a stabilized and precision amount of gear engagement is provided between both gears resulting in a precise amount of rotation imparted to the driven gear per revolution of the drive gear. The precisions of the distant between the gear rotational centers is accomplished by engagement of circumferential surfaces of corresponding cylindrical portions on each gear or provided on associated gears in the gear train of the gear mechanism.
