For KHK standard gears, mechanical structural carbon steel (S45C), mechanical structural alloy steel (SCM440), stainless steel, etc. are used for worms, while cast iron (FC200), phosphor bronze and aluminum bronze, and MC nylon (an engineering plastic) are used for the worm wheel.
Explore precision-engineered worm gear sets for industrial applications. Gear ratios from 2 to 100; Output torque up to 522 Nm
Shafts made of high-alloy steel, gear teeth hardened (induction, case hardening or nitriding), Flanks ground with Klingelnberg or Durand machines. Wheels made of nickel bronze (GK, GM) or centrifugal casting (GZ) for highest mechanical properties and wear resistance.
Framo Morat supplies customised worm gear sets in a centre distance range from 17 to 125 mm, with a max. worm gear diameter of 200 mm. If necessary, Framo Morat calculates the toothing data, defines the materials and surface treatment, and provides advice for lubrication and torque loads.
Our precision ground stainless steel worms and phosphor bronze worm gears provide the best accuracy, smoothest operation, and longest working life. Choose from worm and wheel sets with a 16, 24, 32, 48 or 64 diametral pitch or metric module sets 0.5, 1.0, 1.5, 2.0, 2.5, or 3.0 mod.
MATERIALS for worm and worm gears are generally confined to steel for worms and bronze or cast iron for gears. When steel worms are run with bronze gears at high speeds, the worm is usually hardened with ground threads. Right Hand Worm and Gear. Single, Double, Quadruple Thread Worms.
