EP also sells gear tooth measuring products called GEAR GAGES! Gear Gages decrease mistakes, save time and money when identifying and purchasing gears. These pitch templates are available in nine sets to recognize all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Unusual Pitches. Make reference to the section on GEAR GAGES for catalog quantities when ordering.

Materials recommended for worms is definitely 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. Furthermore to metal and hardenedsteel, worms can be found in stainless, light weight aluminum, 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 since a locking mechanism to carry large weights where reversing action could cause harm or damage. In applications where potential harm is non-existent and self-locking is preferred against backward rotation then use of a single thread worm with a minimal helix angle automatically locks the worm equipment drive against backward rotation.

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

LUBRICATION is an essential factor to boost effectiveness in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The amount of power transmitted at a given temperature boosts as the effectiveness of the gearing improves. Proper lubrication enhances efficiency by reducing friction and warmth.
