REPAIR AND REBUILD
Comprehensive services include the inspection, remanufacturing and repair of all manufacturers’ helical and worm gear drives. With our Maag SP160 gear checker, gears are measured and charted for lead, profile, spacing, runout, and composite accuracy. Precise measurements of housings are achievable with use of computer controlled coordinate measuring machine. Contact checks of mating gears can be verified in the housing, or on our precision contact checking stand. In addition to our general machining capabilities, we have in-house heat treatment facilities, spray welding and dynamic balancing equipment.
ALL COMPLETE REBUILDS INCLUDE NEW FACTORY WARRANTY
REDESIGN AND RERATE
Nuttall’s strong application and design engineering experience has earned us a reputation for producing high- quality and unique helical and worm gear drives. Reverse engineering, ratio changes and drive configuration changes are available for all manufacturers’ gear drives. Increased ratings are often achieved with changes in gear geometry, heat-treating processes, improved gear accuracy, or thermal capacity.
SYSTEM ANALYSIS
Nuttall‘s engineers can develop mathematical models to perform a torsional system study. This system study can be used to determine the natural frequencies of the system for comparison to the forcing frequencies of the components. Coincident frequencies can produce system resonance resulting in severe overload. A change in components can often eliminate system resonance.
QUALITY ASSURANCE
From inspection and teardown to reassembly and complete unit testing, each step is planned and executed within the requirements of our Quality Management System. Our program was designed to meet the strict requirements of the nuclear industry as well as the world recognized standards established by ISO9001:2000. Documented traceability for materials, processes, and testing is part of the Quality Management System that applies to all service work.
