1. A stirring component for a harmonic transmission system, comprising:
a body arranged in an internal chamber at a side of a circular spline away from a flex spline of the harmonic transmission system, the body comprising a coupling hole through which the body is coupled to and rotated with an input shaft of the harmonic transmission system; and
at least one stirring recess arranged on a side of the body adjacent to the circular spline and has a varying depth in an axial direction to stir and push lubricant medium within the internal chamber towards the flex spline during rotation of the body;
wherein the depth of the at least one stirring recess gradually decreases from a middle to both ends of the stirring recess in a circumferential direction.
