Abstract
A planet gear bearing in a planetary gearset including a planet carrier having two side walls which are arranged parallel to one another and accommodate a plurality of planet gear pins in a plurality of axial holes opposite one another on the same axis is disclosed. A plurality of planet gears are rotatably mounted on the planet gear pins by radial rolling-element bearings inserted into central planet gear holes. Stop elements are arranged between the side walls of the planet carrier and the axial sides of the planet gears and act as wear protection of the planet carrier and the planet gears, and as an axial stop for the radial rolling-element bearings of the planet gears. The stop elements are axial needle bearings, which each include an axial bent-up disc and an axial needle ring formed by a plurality of bearing needles and an axial needle cage.
