ABSTRACT
This chapter considers the local geometry of contact of a gear, G, and a mating pinion, P, tooth flank which is used to investigate contact strength of the gear teeth; the conditions of lubrication of the tooth flanks, G and P; gear tooth wear. Interacting tooth flanks of a gear and a mating pinion feature a complex geometry. It is a challenging problem to investigate contact geometry of the tooth flanks of a complex geometry. Three principal configurations of gear shafts are distinguished. They are: parallel-axes gearing; intersected-axes gearing; and crossed-axes gearing. Rotation from the driving shaft is transmitted to the driven shaft by forces acting within the plane of action. This makes it reasonable to consider the interaction of the tooth flanks of the gear and pinion in a plane of action. The chapter illustrates the local geometry of the interacting tooth flanks of a gear and a mating pinion.
