Abstract
A planetary gear device with at least one sun wheel, a ring gear and at least one planetary wheel that is in mesh with the sun wheel as well as with the ring gear, and that is mounted in a rotatable manner on a planetary carrier. A pressure angle (αph) between the tooth flanks of the teeth of the ring gear and of the planetary wheel, which are in mesh with each other during the main rotational direction of the planetary carrier, is larger than a pressure angle between the tooth flanks of the teeth of the planetary wheel and of the sun wheel, which are in mesh with each other at the same time. What is further proposed is a jet engine of an aircraft with such a planetary gear device.
