EP also sells gear tooth measuring gadgets called GEAR GAGES! Gear Gages decrease 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”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Uncommon Pitches. Refer 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 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 are available in steel, hardened metal, stainless, aluminium, nylon and nonmetallic (phenolic).

SAFETY PROVISION: Worm gearing should not be used since a locking mechanism to hold large weights where reversing action could cause harm or injury. In applications where potential damage is nonexistent and self-locking is preferred against backward rotation then use of an individual thread worm with a low helix angle immediately locks the worm gear 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 single threads yield higher ratios than multiple threads. All EP inc. worm gear sets are available with either remaining or right hands threads. EP inc. worm gear sets are offered with Single, Double, Triple and Qua-druple Threads.

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

Worm wheel gear is made use of to fit in any kind of day-to-day routine.
