Helical Gearing | Delroyd Worm Gear

The exclusive use of the involute helicoid thread form on the worm and gear provides for high efficiencies and long service life on draglines and shovels. The hardened,ground and polished alloy steel worm develops a smooth, work hardened surface on the bronze gear. For this reason, the worm gears wear in and improve with prolonged service while other gears are wearing out.
