Gear repair and gearbox repair services repair gears, gearboxes and speed reducers. Gears are mechanical devices that transmit power and motion between axes. They differ in terms of type, teeth, direction, size, features, and materials of construction.


Gearbox Components

Gearboxes consist of a set of gears, shafts, and bearings that are factory-mounted in an enclosed, lubricated housing. They are sometimes called gearheads or speed reducers. Speed reducers come in a broad range of sizes, capacities and speed ratios. Their function is to convert the input provided by a prime mover into an output of lower revolutions per minute (RPM) and correspondingly higher torque. Gear and gearbox repair services that specialize in speed reducers with spur, helical, planetary, harmonic, or worm gearing arrangements are commonly available.


Gearbox Functions

Gear repair and gearbox repair services may perform stress analysis, teardown, cleaning, refurbishing or replacing, assembly, painting, and testing and inspection services. Gear repair services may also perform activities such as shaping, hobbing, and grinding. Gear stress analysis is performed in accordance with published standards for gear transmission systems. Gear refurbishing services specialize in rebuilding gears with all new materials. Gear repair and gearbox replacement services are also commonly available. These gear and gearbox repair services remove damaged components and systems for replacement and subsequent repair. Gear painting, gear testing, and gear inspection services may then perform secondary operations. Gear shaping services, gear hobbing services, and gear grinding services perform specialized activities.
