Re-Ring and Gear Hobbing of Steel Spur Gear for the Printing Industry

Steel Spur Gear A customer from the printing industry came to Butler Gear Enterprises, LLC. to re-ring and hob a steel spur gear. We took the existing material (steel) from the ring manufacturer and removed the existing teeth that were on the original gear. Then we reapplied the new ring to the outside of the gear and reattached it by drilling, tapping and welding. All of this was accomplished using VTL lathes and hobbing equipment, and we held tolerances down to ±.005". The final part measured 60.138" in outside diameter, 55.600" in inside diameter, and 2.500" long. After a thorough inspection, we shipped the 3000 lbs gear to a location in the Midwest.
