Main Drives for Bar & Wire Rolling Mills
NGC’s main driving gearbox technology for bar and wire rolling provides solutions for driving systems of production lines of bars, wires, and profiles. These gearboxes are designed by arranging vertical gearboxes and horizontal gearboxes to ensure the shapes and sizes of rolling products. The horizontal gearboxes are driven by parallel shafts, and the vertical gearboxes are driven by spiral bevel gears and parallel shafts. The structure is a single input double output structure or a triple output structure, which can transmit and distribute the power of the motor to two or three rollers, which then will reach the torque and speed required by rolling through reduction ratio.
NGC’s main driving gearbox also features compact structure, compact resistance and steady operation. It can be matched with closed or short stress path rolling mills when used, and can rationally customize the vertical and horizontal structured gearboxes and flat-vertical switching systems according to the requirements of rolling technology of the production lines.
