11.3.1 Methods of Generation Generation is the basic process in the manufacture of bevel and hypoid gears in that at least one member of every set must be generated. The theory of generation as applied to these gears involves an imaginary generating gear, which can be a crown gear, a mating gear, or some other bevel or hypoid gear.The gear blank or workpiece is positioned so that when it is rolled with the generating gear, the teeth of the workpiece are enveloped by the teeth of the generating gear. In the actual production of the gear teeth, at least one tooth of the generating gear is described by the motion of the cutting tool or grinding wheel. The tool and its motion are carried on a rotatable machine member called a cradle, the axis of which is identical with the axis of the generating gear. The cradle and the workpiece roll together on their respective axes exactly as would the workpiece and the generating gear. The lengthwise tooth curve of the generating gear is selected so that it is easily followed with a practical cutting tool and mechanical motion. Figure 11.8 illustrates the representation of a generating gear by a face-mill cutter. Figure 11.9 shows the basic machine elements of a bevel-gear face-mill generator. Most generating gears are based on one of two fundamental concepts. The first is complementary crown gears, where two gears with 90 pitch angles fit together like mold castings. Each of the crown gears is the generating gear for one member of the mating set. Gears generated in this manner have line contact and are said to be conjugate to each other. With the second concept, the teeth of one member are form-cut without generation. This member becomes the generating gear for producing the mating member. Again, gears generated in this manner are conjugate to each other.

11.3.2 Localization of Contact Any displacement in the nominal running position of either member of a mating conjugate gear set shifts the contact to the edges of the tooth. The result is concentrated loading and irregular motion. To accommodate assembly tolerances and deflections resulting from load, tooth surfaces are relieved in both the lengthwise and profile directions.The resulting localization of the contact pattern is achieved by using a generating setup which is deliberately modified from the conjugate generating gear.

one spindle, and the mating gear or a control gear is mounted on the other spindle. Tooth contact is evaluated by coating the teeth with a gear-marking compound and running the set under light load for a short time. At the same time, the smoothness of operation is observed. Spacing errors and runout are evaluated by noting variations in the contact pattern on the teeth around the blank. Poor surface finish shows up as variations within the marked contact pattern. Tooth size is measured by locking one member and rotating a tooth of the mating member within the slot to determine the backlash. The contact pattern is shifted lengthwise along the tooth to the inside and outside of the blank by displacing one member along its axis and in the offset direction. The amount of displacement is used as a measure of the set s adjustability. It is normal practice for tooth spacing and runout to be measured with an additional operation on inspection equipment designed specifically for that purpose. AGMA publication 2011-A98 specifies allowable tolerances for spacing and runout based on diametral pitch and pitch diameter. Double- and single-flank test equipment can be used to measure tooth-profile errors, tooth spacing, and runout. The test equipment has transducers on the work spindles, and the output data are in chart form. The output data not only provide a record of the quality of the gear set, but can also be related to gear noise. Three-dimensional coordinate-measuring machines can be used to compare the actual gear-tooth geometry with theoretical data.
