EP also sells equipment tooth measuring devices called GEAR GAGES! Gear Gages reduce mistakes, save money and time when identifying and purchasing gears. These pitch templates can be found in nine sets to identify all the regular pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.
Materials recommended for worms is certainly hardened steel and bronze for worm gears. However, depending on the application form unhardened metal worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms are available in stainless, aluminum, bronze and nylon; worm gears can be found in steel, hardened metal, stainless, aluminium, nylon and nonmetallic (phenolic).
Basic safety PROVISION: Worm gearing shouldn’t be used as a locking mechanism to hold large weights where reversing action can cause harm or damage. In applications where potential harm is nonexistent and self-locking is preferred against backward rotation after that use of an individual thread worm with a minimal helix angle instantly locks the worm equipment drive against backward rotation.
RATIOS of worm equipment sets are dependant on dividing the amount of teeth in the apparatus by the amount of threads. Thus one threads yield higher ratios than multiple threads. All EP inc. worm gear sets can be found with either still left or right hand threads. EP inc. worm gear sets can be found with Single, Dual, Triple and Qua-druple Threads.
LUBRICATION is an essential factor to improve effectiveness in worm gearing. Worm gear 
action generates considerable temperature, decreasing efficiency. The quantity of power transmitted at a given temperature increases as the effectiveness of the gearing raises. Proper lubrication enhances efficiency by reducing friction and warmth.
