EP also sells equipment tooth measuring devices called Equipment GAGES! Gear Gages decrease mistakes, save money and time when identifying and ordering gears. These pitch templates are available in nine sets to identify all the standard 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 GEAR GAGES for catalog numbers when ordering.
MATERIAL 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 steel and hardenedsteel, worms can be found in stainless, light weight aluminum, bronze and nylon; worm gears can be found in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).
Protection PROVISION: Worm gearing shouldn’t be used since a locking mechanism to hold large weights where reversing action can 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 instantly 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 number of threads. Thus one threads yield higher ratios than multiple threads. All EP inc. worm gear sets can be found with either left or right hands threads. EP inc. worm gear sets are offered with Single, Double, 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 raises as the efficiency of the gearing boosts. Proper lubrication enhances performance by reducing friction and high temperature.
