EP also sells equipment tooth measuring gadgets called GEAR GAGES! Gear Gages decrease mistakes, save money and time when identifying and ordering gears. These pitch templates can be found in nine sets to identify all the regular pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on Equipment GAGES for catalog figures when ordering.

MATERIAL recommended for worms is hardened steel and bronze for worm gears. However, depending on the application form unhardened steel worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms are available in stainless, aluminium, bronze and nylon; worm gears can be found in steel, hardened metal, stainless, light weight aluminum, nylon and non-metallic (phenolic).

Protection PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry heavy weights where reversing actions could cause harm or damage. In applications where potential damage is non-existent and self-locking is preferred against backward rotation then use of an individual thread worm with a low helix angle immediately locks the worm equipment drive against backward rotation.

RATIOS of worm gear sets are dependant on dividing the number of teeth in the apparatus by the amount of threads. Thus single threads yield higher ratios than multiple threads. All EP inc. worm gear sets are available with either still left or right hands threads. EP inc. worm gear sets can be found with Single, Dual, Triple and Qua-druple Threads.

LUBRICATION is an essential factor to improve performance in worm gearing. Worm equipment action generates considerable high temperature, decreasing efficiency. The amount of power transmitted at confirmed temperature boosts as the efficiency of the gearing increases. Proper lubrication enhances efficiency by reducing friction and high temperature.
