US Patent 11428310 Stepped spindle

A rotatable transmission component rotatable about an axis of rotation includes a first mounting member spaced apart from a second mounting member and a spindle extending from the first mounting member to the second mounting member. An axial location of the spindle between the first and second mounting members is maintained by interference connections between the spindle and the first and second mounting members. An outer diameter of a first end of the spindle is larger than an outer diameter of a second end of the spindle. The rotatable transmission component may be a planet carrier, and a planet gear may be supported on the spindle.
