Small G30A planetary gearboxes from Pittman, engineered to complement five series of dc motors, are designed for maximum torque density and durability and allow a range of output torques and speeds. The mounting profile of the gearbox is 1.20 in. diam or, when the optional mounting flange is used, 1.50 in. square. Lengths vary between 1.33 and 2.02 in., depending on the gear reduction. The gearboxes are offered in 14 standard reduction ratios ranging from 4:1 to 1296:1 and allow maximum output loads of 350 to 1250 oz-in. In addition, custom gear ratios can be configured to suit nearly any application requirement. Designed for challenging motion applications, including medical devices, these gearboxes incorporate sintered-steel planet gears to promote high torque capacity and low audible noise in a compact design. Gearbox output is directed through a Type 416 stainless-steel shaft and a sintered-metal output bearing.
