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

Description:

The Cone Drive VV20-35-V8A 400:1 Ratio Gear Reducer is used in industrial power transmission systems to deliver very high torque multiplication with extreme speed reduction for heavy-duty mechanical applications. It is a double-enveloping worm gear reducer designed for high load capacity, shock resistance, and efficient torque transfer in compact drive assemblies. Commonly installed in conveyors, material handling systems, bulk processing equipment, and industrial machinery requiring ultra-low output speed with high torque output. Maintenance teams, OEM manufacturers, and system integrators use this part for replacement of failed high-ratio reducers, retrofit of heavy drive systems, and restoration of controlled low-speed torque applications.

Applications:

The Cone Drive VV20-35-V8A is used in industrial mechanical drive systems to achieve a 400:1 reduction ratio for very low-speed, high-torque output applications. It is commonly applied in conveyor drives, rotating tables, mining equipment, mixers, and heavy process machinery where precise low-speed control and high torque multiplication are required.
