Repaired gearboxes 'better than new'

26 July 2015

Renold Gears can provide a high quality, reliable and rapid industrial gearbox repair service, and claims that a gearbox it has repaired is usually better than when it was new, in terms of performance, efficiency and future maintenance requirements.

A repair can cost up to 40 percent less than a new replacement, but when a new unit is required, Renold's engineers can conduct a site survey to ensure that the new unit will fit exactly into the footprint and space envelope of the previous, regardless of the original manufacturer.

Replacement worm gears can be manufactured from original drawings or by employing Renold's novel method of reverse engineering by taking a profile from a worm shaft on site, anywhere in the world, using a profile plug lifting technique.

Renold is able to repair any gearbox made by any manufacturer to its original specifications or higher, including SEW, Highfield, Sumitomo, Hansen, David Brown, Siemens, Rossi and Falk. The service department will also ensure that Renold, Croft and Holroyd worm gear units are rebuilt using genuine components from the original manufacturer. When a complete overhaul is necessary electron beam welding can be used on the wormwheel for extra security on highly stressed applications.

Every stage of the repair process, including cutting, grinding, heat treatment and inspection is conducted within Renold Gears’ factory by its own engineers. An industrial gearbox repaired by Renold leaves the factory with a 12 month warranty.
