Gear pair consisting of a crown gear and of a pinion gear

摘要

The crown wheel (1) and the pinion (2) are positioned in a right angle in relation to each other. The pinion (2) is provided with an inner (7) and an outer ring (6). The inner ring (7) has a curved outer surface, engaging with a complementary inner area (8) at the teeth (5) of the crown wheel (1). The contact zones between the teeth of the pinion (3) with the teeth of the crown wheel (5) increase in size towards the center caused by a decrease in height.
