Mill drive trains come in many shapes and sizes. The most common is a bank of worm gear reducers driven by a single motor. Individual banks are employed for each mill section (i.e., breakdown, fin, and sizing sections). For high-speed or high-torque applications, it is often necessary to add forced oil-cooling to the system. On larger mills, it is justifiable to employ individual pass drive system using planetary or helical parallel-shaft reducers. For mills that operate over a wide speed range (e.g., >2:1), the use of a multi-speed transmission shift box is often used.
In our worm gear reducers, we utilize Cone Drive double-enveloping worm gearsets. Cone Drive is the world leader in double-enveloping worm gear technology. Size for size, these gearsets are the most powerful worm gearsets in the world and provide several distinct advantages over cylindrical worm gearing, including increased torque throughput, improved accuracy, and extended life.
