EP also sells gear tooth measuring gadgets called Equipment GAGES! Gear Gages reduce mistakes, save money and time when identifying and buying 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, Fine Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on GEAR GAGES for catalog quantities when ordering.
Materials recommended for worms can be hardened steel and bronze for worm gears. Nevertheless, depending on the application unhardened steel worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms are available in stainless, light weight aluminum, bronze and nylon; worm gears can be found in steel, hardened steel, stainless, aluminum, nylon and non-metallic (phenolic).
SAFETY PROVISION: Worm gearing shouldn’t be used since a locking mechanism to hold heavy weights where reversing action could cause harm or damage. In applications where potential damage is non-existent and self-locking is desired against backward rotation after that use of a single thread worm with a minimal helix angle automatically locks the worm equipment drive against backward rotation.
RATIOS of worm gear sets are dependant on dividing the amount 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 still left or right hand 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 heat, decreasing efficiency. The amount of power transmitted at confirmed temperature raises as the efficiency of the gearing raises. Proper lubrication enhances effectiveness by reducing friction and warmth.
