EP also sells equipment tooth measuring devices called GEAR GAGES! Gear Gages reduce mistakes, save time and money when identifying and buying gears. These pitch templates are available 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 Uncommon Pitches. Make reference to the section on Equipment GAGES for catalog numbers when ordering.

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

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

RATIOS of worm gear sets are determined by dividing the number of teeth in the gear by the number of threads. Thus one threads yield higher ratios than multiple threads. All EP inc. worm equipment sets can be found with either remaining or right hands 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 efficiency in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The quantity of power transmitted at confirmed temperature raises as the efficiency of the gearing improves. Proper lubrication enhances effectiveness by reducing friction and heat.
