Not illustrated. 1915 Excerpt: ...for a strong drive and an angular adjustment. In the case of the work-supporting parts, it is difficult to bring the cutting point close to the bearing on account of the necessity for plenty of clearance below the work for the hob and its driving gear. The matter of design of the driving mechanism for the hob and the work is a difficult one. Not only must it be rigid for the sake of accuracy, as previously explained, but careful attention must be given to durability as well. It requires great skill to design a durable mechanism for the purpose within the limitations imposed--in the cutter head by the necessity for reducing the overhang, and in the work table by the high speed required for cutting small gears. Since the indexing wheel works constantly and under considerable load, both the wheel and worm must be built of such materials as will preserve their accuracy after long continued use. Particular attention should be given to the homogeneity of the material of the index worm-wheel, to make sure that it does not wear faster on one side than on the other. The field of the hobbing process for cutting spur gears has not yet been definitely determined. In some work it appears to have certain advantages over the usual type of automatic gearcutting machine, while in other cases it falls behind. It will doubtless require continued use, with a variety of work, and for a considerable length of time, to determine just what cases are best suited for the hobbing machine, and what for the machine with the rotating disk cutter. It is not probable that in the future either of them will occupy the field to the exclusion of the other. Designing a Hob for Robbing Spur Gears.--In explaining the methods used in the design of hobs for spur gears, it is best to assume a pract...
