. 7 The science that deals with measurement. Gears are usually assembled into gear boxes, which are generally produced by gear manufacturers. The assembly 8 of gear boxes may involve the purchase of bearings, shafts, gear-box housings, seals, lubricants, and miscellaneous items. Most gear box manufacturers produce their own gears and shafts, but they usually purchase the remaining items needed to produce gear boxes. Frequently, the housings for the gear boxes are produced from purchased castings but subsequent machining of mountings for shafts, bearings, and fasteners is done by the gear box producer. Such machining is done to precise tolerances, because misalignment can result in premature wear or failure. After the gears are assembled into gear box, the whole assembly is tested for smoothness of operation and alignment.
