A rear sprocket includes a sprocket body, a plurality of sprocket teeth, a plurality of spline teeth, a maximum spline distance, and a radial bottom distance. Each of the plurality of spline teeth has a spline top. A maximum spline distance is defined from the rotational center axis to the spline top. A radial bottom distance is defined from the rotational center axis to one of the plurality of bottom center points. The maximum spline distance is greater than the radial tooth bottom distance. A spline tip of each of the plurality of spline teeth is located radially inward from a tooth profile of each of the plurality of sprocket teeth in a radial direction.
一种后链轮,包括链轮主体、多个链轮齿、多个花键齿、最大花键距离和径向齿底距离。多个花键齿中的每一个都具有花键顶。最大花键距离限定为从旋转中心轴线到花键顶。径向齿底距离限定为从旋转中心轴线到多个齿底中心点之一。最大花键距离大于径向齿底距离。多个花键齿中的每一个的花键顶位于在径向方向上从多个链轮齿中的每一个的齿廓径向地向内。
