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
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
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.
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.
