Dynatork Wormwheel 60W3
Free Piston Air Motor with Worm Gearbox
Design
The worm gearbox type 63W have casing, feet and flanges, and are manufactured in high strength UNI 5076 aluminium. The worm is manufactured out of nickel-chromium-molybdenum steel alloy 18NICrMo4 hardened and ground. The worm wheel is of a special bronze alloy on a cast iron hub. Gear ratios from 7:1 to 100:1 provide speed regulation and torque amplification to suit most requirements. Special sealing components keep water and dust from entering the worm box inner parts, as well as preventing the lubricant from leaking.
