ABSTRACT
This chapter discusses the examples of perfect gearings with point contact between tooth flanks of a gear and a mating pinion. It outlines an approach to generating tooth flanks in perfect gearing with point contact between tooth flanks of a gear and a mating pinion. The chapter considers possible types of auxiliary generating racks. It also discusses the geometry of tooth flanks of perfect crossed-axes gears with point contact. Potentially, the total number of possible types of gearings with point contact between the tooth flanks of a gear and a mating pinion is large. The goal is to illustrate a possibility of designing gearings of the type under consideration that are already used in the industry. A schematic of gearing composed of a cylindrical involute worm that is engaged in mesh with a cylindrical involute helical gear is illustrated in this chapter.
