Worm wheel gear

EP also sells gear tooth measuring products called Equipment GAGES! Gear Gages reduce mistakes, save money and time when identifying and purchasing gears. These pitch templates can be found in nine sets to recognize all the regular 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 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 metal and hardenedsteel, worms can be found in stainless, aluminium, bronze and nylon; worm gears can be found in steel, hardened steel, stainless, light weight aluminum, nylon and nonmetallic (phenolic).

SAFETY PROVISION: Worm gearing shouldn’t be used as a locking mechanism to hold heavy weights where reversing action could cause harm or damage. In applications where potential harm 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 still left or right hand threads. EP inc. worm gear sets are offered with Single, Dual, Triple and Qua-druple Threads.

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

This is exactly how Worm wheel gear can be utilised for your advantage.
