Worm wheel gear

EP also sells equipment tooth measuring gadgets called Equipment GAGES! Gear Gages reduce mistakes, save money and time when identifying and ordering gears. These pitch templates are available in nine sets to recognize all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.

MATERIAL recommended for worms is definitely hardened steel and bronze for worm gears. However, depending on the application form 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, aluminium, bronze and nylon; worm gears can be found in steel, hardened steel, stainless, aluminium, nylon and non-metallic (phenolic).

Protection PROVISION: Worm gearing shouldn’t be used because a locking mechanism to carry large weights where reversing actions can cause harm or injury. In applications where potential harm is nonexistent and self-locking is preferred against backward rotation then use of a single thread worm with a low helix angle immediately locks the worm gear drive against backward rotation.

RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the number of threads. Thus solitary 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 are offered with Single, Dual, Triple and Qua-druple Threads.

LUBRICATION is an essential factor to improve efficiency in worm gearing. Worm gear action generates considerable high temperature, decreasing efficiency. The quantity of power transmitted at confirmed temperature raises as the effectiveness of the gearing boosts. Proper lubrication enhances performance by reducing friction and heat.
