Worm Equipment Reducers generally known as worm gearbox or worm velocity reducers. Worm gear reducers are being used for speed decrease and increasing the torque for electrical motor drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C face flange or apply a coupling. If you desire a coupling for the output or input shaft look at our coupling section for choosing the coupling. You can expect four assemblies left hands and right side and double end result shaft and shaft source and shaft productivity. Interchangeable with most worm equipment manufactures. See data sheet in product review for diamensions. If you don’t see your type, please Contact Us.
EP GEARS also offers gear tooth measuring gadgets called Equipment GAGES! Gear Gages decrease mistakes, save money and time when identifying and buying gears. These pitch templates can be found in nine sets to recognize all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on GEAR GAGES for catalog numbers when ordering.
Materials recommended for worms is definitely hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened metal worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be purchased in stainless, aluminium, bronze and nylon; worm gears are available in steel, hardened steel, stainless, aluminium, nylon and non-metallic (phenolic).
Safe practices PROVISION: Worm gearing should not be used since a locking mechanism to hold major weights where reversing action could cause harm or harm. In applications where potential harm is nonexistent and self-locking is preferred against backward rotation then use of a single thread worm 
with a minimal helix angle automatically locks the worm gear drive against backward rotation.
