Rolling Mill Gearbox Repair
A customer recently sent in a gearbox that is part of their rolling mill. The rolling mill uses a metal alloy to make engine bearings for large Diesel engines. This line on the mill brings in thicker material and rolls it out thinner to the desired thickness. Much like a rolling pin does with dough. The problem with the gearbox was when it was put under load it would vibrate like crazy. When the gearbox ran unloaded it ran smooth. It was found that the shaft was bent, and the gears were in bad shape. We worked with a quality manufacturer of gears here in Indiana to have the teeth re-profiled and made new gears as necessary. Horner supplied and installed new bearings and seals and reassembled the gearbox. Field Service will reinstall the gearbox.
