as wemight expect, the laws of tooth action are similar in bevel gearsto those in the case of spur gears. The profile of the tooth in theformer case, however, is based, not on the real radius of the pitchcone, but on the radius of the normal cone ; and in the develop-ment of the outline the latter… … Fig. 42. The teeth of bevel gears, being simply projections with bases onthe pitch cones, have a varying cross-section decreasing toward thevertex ; also a trapezoidal section of root, the latter section actingas a beam section to resist the cantilever moment due to the toothload. The arms must, as…
