Novel designs of pre-heater drive are being produced by Renold Gears in Rochdale, for export and installation in the rapidly growing market for fossil fuel power stations in China
All service/repair units carry a 12-month warranty as standard.
The service can include electron beam welding of the worm-wheel rim and centre to give added security.
The high security fit of electron beam welding allows transmission of power under extreme shock load conditions.
Complementing its factory-based repairs, Renold can provide a range of on-site and support services, which can include: on-site maintenance and in-situ repairs; plant surveys for planned maintenance; and technical design expertise for all application and design requirements.
Renold expertise was recently called upon when a major automotive manufacturer experienced persistent stoppages to one of its main conveyor lines, due to repeated failure of a non-Renold gearbox drive and layshaft assembly.
Renold engineers using laser alignment equipment found that two pairs of opposing, rigidly mounted gear couplings, connected by common layshafts, were out of alignment.
Thus the gear couplings and the layshafts were permanently under stress.
A complication was that the conveyor fixtures that located the gear couplings were an integral part of the building structure and could not be re-sited.
The solution was to install two Renold GF1-SA internal gear couplings (which incorporate a misalignment capability) per side to replace the rigidly mounted couplings, and new layshafts manufactured from a more resilient EN 24B material.
Conveyor stoppages due to drive coupling failure have not occurred since the modification.
Renold Gears Sales Director, Roger Godson, comments: 'Renold Gears has over 100 years' accumulated experience in the manufacture of precision gears and is one of the very few British-based gear manufacturing companies still in existence.
Using reverse engineering techniques we have the capability to repair any gear assembly - irrespective of size, configuration or origin, and we have a comprehensive OEM service and repair programme for Renold, Holroyd, Croft and Carter products.
Our experience and unrivalled expertise mean that we can provide a level of service, either in-house or on-site, second to none'.
