The AutomationDirect (Cumming, GA) mechanical power transmission lineup now includes larger 325 frame size IronHorse cast iron worm gearboxes. These 3.25” input to output shaft distance gearboxes are available in ratios of 10:1, 15:1, 20:1, 30:1 40:1 & 60:1 with outputs in left hand shaft, right hand shaft, dual shaft and hollow shaft. The 325 gearbox C-face interfaces match NEMA 56C, 145TC and 182/4TC motor frame sizes.
Constructed of cast iron one-piece housings; the worm gearboxes are designed to change drive direction by 90 degrees, drive a load at a reduced fixed ratio of the motor speed, and increase output torque by the same ratio. Worm gearboxes are used when space is at a premium, such as for conveyors, or to simplify mechanical design. IronHorse gearboxes are mountable in any direction, except motor pointing up.
