EP also sells gear tooth measuring gadgets called GEAR GAGES! Gear Gages decrease mistakes, save time and money when identifying and ordering 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, Great Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on GEAR GAGES for catalog amounts when ordering.

MATERIAL recommended for worms can be 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 metal, stainless, aluminium, nylon and non-metallic (phenolic).

Protection PROVISION: Worm gearing shouldn’t be used because a locking mechanism to carry weighty weights where reversing action could cause harm or injury. In applications where potential harm is nonexistent and self-locking is desired against backward rotation after that use of a single thread worm with a low helix angle immediately locks the worm equipment drive against backward rotation.

RATIOS of worm equipment sets are dependant on 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 equipment sets are available with either 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 high temperature, decreasing efficiency. The amount of power transmitted at a given temperature boosts as the performance of the gearing improves. Proper lubrication enhances performance by reducing friction and warmth.
