Cone Drive VV20-35-V8A Double Enveloping Worm Gear Reducer

The Cone Drive VV20-35-V8A is a 400:1 double-enveloping worm gear reducer designed for ultra-low output speeds and very high torque in heavy industrial power transmission systems. Housed in a heavy-duty cast iron gearbox with an oil-bath lubrication system, it accepts a solid-shaft input (motor-coupled input available depending on configuration) and provides a solid-shaft output, with center distance tied to the 20–35 frame size class. The double-enveloping worm gear design delivers high load capacity and efficient torque transfer, while controlled industrial-grade backlash and base- or flange-mounting options support reliable integration into a wide range of installations. Commonly installed in conveyors, material handling systems, bulk processing equipment, and heavy process machinery such as rotating tables, mining equipment, and mixers where precise low-speed torque is required.
