Abstract
A planet pin includes a center axis and an outer contour that runs at a distance r(x) from the center axis. The distance r(x) is dependent on an axial position x in at least one longitudinal portion. For at least one axial position interval [x1, x2], the distance r(x), for all x∈[x1, x2], of the outer contour from the center axis is r(x)=l(x)+g(x)+o(x), where l(x) is a linear function, g is constantly zero or convex on the interval [x1, x2], and o(x0)=0 applies for at least one x0∈]x1, x2[. The function o is concave on the interval [x1, x0], convex on the interval [x0, x2], and decreasing in x0.
