A planet gear includes an annular planet gear ring including an annular planet gear rim. The annular planet gear rim has an inner radius and an outer radius. The inner radius and the outer radius define a rim thickness therebetween. The annular planet gear rim further has a bending stress neutral axis. The bending stress neutral axis radius and the rim thickness define a ratio including values ina range from and including about 4 to and including about 9. The invention discloses a gear assembly including a planet gear, and a turbine. 一种行星齿轮包括环形行星齿轮缘，该环形行星齿轮缘具有沿着整个轴向长度的恒定的内半径和限定为到齿轮齿根的径向距离的外半径。环形行星齿轮缘还具有限定在恒定的内半径与外半径之间的中途点处的平均缘半径。平均缘半径和缘厚度限定比率，该比率包括从(且包括)约4至(且包括)约9的范围内的值。公开包括行星齿轮的齿轮组件和涡轮机。
