The highlight of Zhongnuo Machinery's new leveling machine is its unique pull-out roller functionality. This innovative feature allows for seamless roller replacement, ensuring uninterrupted workflow and reducing downtime. The ability to quickly and effortlessly replace rollers is a game-changer for construction professionals, enabling them to optimize their productivity and efficiency on the job site.
Delta Steel Technologies Inc., a second-generation manufacturing company in Irving, Texas, builds and repairs machinery for steel mills across the country. In its 226,000-sq.-ft. facility, the company’s 120 employees design and manufacture customized stretch levelers, rotary shears, temper mills, and cut-to-length lines. All are used to convert rough coils of steel into flat, precision-cut material suitable for use by automakers, appliance producers, and other manufacturers of sheet metal components and assemblies.

The company also refurbishes, remanufactures, and retrofits legacy equipment; performs cylinder and gearbox repairs; does custom machining and fabrication; and offers turnkey installations of its systems. And many of these systems are highly automated to maximize throughput. Simply put, Delta Steel’s goal is to deliver whatever its customers need to process steel efficiently and profitably.

During one recent project, however, the manufacturer ran into a snag. After delivering the winning bid on a roller leveler, President Joseph Savariego and his design team found that the gearboxes in a critical subassembly had to be placed closer together than they liked. They knew that this configuration would make it difficult for the customer to service the machine in the future.

This roller leveler uses 11 rollers total, five above the sheet and six below. Each roller is attached to a driveshaft, and each driveshaft connects to a gearbox driven by its own 150-HP motor. The designers needed to stack the two rows of components one atop the other to fit everything into the limited space, but this restricted access to the bottom row of drive components. So they developed a slide mechanism that would allow technicians to easily disconnect each gearbox and motor combination from the driveshaft and simply pull it back and out of the way for servicing. Despite this space-saving arrangement, however, a compact but powerful gearbox would still be required.

Resolution
Delta Steel decided to reach out to electromechanical system provider NORD DRIVESYSTEMS, with which it had worked for a number of years. Application Engineer Jeff Wittrock recommended an SK5207 series MaxxDrive large industrial gear unit in a parallel-axis configuration and 14-to-1 drive ratio. With a Unicase one-piece housing, symmetrical design, and extremely high power density for its size, the gearbox would provide the torque, performance, and service life needed for this demanding application.
