Worm Gear Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are being used for speed reduction and raising the torque for electric electric motor drives. You can choose to mount your NEMA motor to the reducer by using the NEMA C confront flange or apply a 
coupling. In the event that you need a coupling for the result or input shaft look at our coupling section for choosing the coupling. We offer four assemblies left hand and right side and double productivity shaft and shaft insight and shaft end result. Interchangeable with most worm equipment manufactures. See info sheet in product review for diamensions. Unless you see your type, you should E MAIL US.
EP GEARS also markets gear tooth measuring equipment called GEAR GAGES! Gear Gages decrease mistakes, save money and time when identifying and ordering gears. These pitch templates can be purchased in nine sets to identify all the typical pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on GEAR GAGES for catalog figures when ordering.
MATERIAL recommended for worms can be 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 steel and hardenedsteel, worms are available in stainless, metal, bronze and nylon; worm gears are available in steel, hardened steel, stainless, lightweight aluminum, nylon and non-metallic (phenolic).
SAFETY PROVISION: Worm gearing should not be used because a locking mechanism to hold hefty weights where reversing action could cause harm or damage. In applications where potential harm is non-existent 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.
