Abstract
A sprocket wheel or double helical gear loader for a machine which generates gears by pinion shaped cutters. The machine includes a gear bearing table having a centering device and a rotatable supporting base. The loader includes a turntable which advances step-by-step about an axis of rotation of the base. The turntable includes on its periphery a plurality of gear holders, which can be intermittently positioned at cutting stations and a discharge station of completed gears. A gear is secured to the turntable through gripping arms, which surround the gear about a whole of the gear perimeter except for an aperture. A cutter passes through the aperture. The gripping arms are movable to accommodate gears of different sizes.
