Stadtfeld Introduction At the beginning of the twentieth cen-tury, motion and torque were trans-mitted to the driving wheels of the first automobiles with straight bevel gears. With slightly curved (episinoid) teeth, bevel gears were an improved alternative. Both straight and curved bevel gear teeth

I understand that the only way to make "correct" bevel gears is with a special (gleason?) shaping type machine because of the way the teeth on a bevel gear converge in the center of the cone.
Read More2015-4-9 Bevel gears are widely used because of their suitability towards transferring power between nonparallel shafts at almost any angle or speed. Spiral bevel gears, in comparison to straight or zerol bevel gears, have additional overlapping tooth action which creates a smoother gear mesh.

The meshing of the sprocket teeth and chain links generates a vibration profile that is almost identical to that of a gear set. The major difference between these two machine-train components is that the looseness or slack in the chain tends to ...
