Abstract
A rolling-element bearing transmission includes a rotor configured to rotate a shaft relative to a stator and a rotatable output ring that includes a first rolled-on surface element. The shaft includes at least one second rolled-on surface element, and the stator includes a third rolled-on surface element. First and second pluralities of rolling elements are located between the shaft and the stator and between the shaft and the output ring. Also, a transmission mechanism transmits a rotary motion of the shaft to the output ring with a speed reduction such that the output ring rotates at a lower speed than the shaft.
