To minimize costs associated with modifications requiring a prolonged outage of operation, ABS and MGS Gears provide customized design and manufacture solutions, 100% interchangeable as well as repowered. All of which adapt to the mill’s original configuration regardless of their antiquity.
In this case, due to the limitations and restrictions of the main drive (clutch, motor, and slow rotation system) foundation, the proposed solution could not modify the original position of the engine or clutch.
Original dimensions of the foundation had to remain unchanged, same initial Flender H2SH17 gearbox input and output shaft lines and diameters and pneumatic power connection of the EATON double drum clutch.
Given the suboptimal condition of the gearbox, the solution called for an increase of the gears. ABS solved this situation through a unique design of superimposed intermediate stage that maintained the same input and output lines. This design increased the service factor from FS 1.7 to FS 2.6.
To optimize maintenance, ABS also replaced the lubrication unit for a dual-filter, dual-drive lubrication system with both stand-by and operation pumps working in parallel, making it possible to perform routine maintenance without a stop in production via the bypass system which blocks the flow.
