EP also sells gear tooth measuring products called Equipment GAGES! Gear Gages reduce mistakes, save time and money 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 GEAR GAGES for catalog numbers when ordering.

MATERIAL recommended for worms is usually hardened steel and bronze for worm gears. Nevertheless, 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 steel and hardenedsteel, worms are available in stainless, aluminum, bronze and nylon; worm gears are available in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).

SAFETY PROVISION: Worm gearing should not be used as a locking mechanism to hold large weights where reversing action could cause harm or damage. In applications where potential damage is non-existent and self-locking is desired against backward rotation then use of a single thread worm with a minimal helix angle immediately locks the worm equipment drive against backward rotation.

RATIOS of worm equipment sets are determined by dividing the amount of teeth in the gear by the number 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 can be an essential factor to improve effectiveness in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The amount of power transmitted at confirmed temperature increases as the efficiency of the gearing boosts. Proper lubrication enhances efficiency by reducing friction and temperature.
