Zusammenfassung:	A small-tooth-difference planetary speed-reduction mechanism and a tooth shape design method therefor. The method comprises: constructing a small-tooth-difference planetary speed-reduction mechanism, the mechanism comprising a planetary gear (1), an elastic gear ring (2) and a limiting gear carrier (3), the elastic gear ring (2) being provided with first inner teeth (21) capable of meshing with first outer teeth (11) of the planetary gear (1) and second outer teeth (22) capable of meshing with second inner teeth (31) of the limiting gear carrier (3), and the planetary gear (1) being driven by an eccentric shaft (4) and arranged eccentrically relative to the limiting gear carrier (3), such that the elastic gear ring (2) and the planetary gear (1) are deformed upon meshing; making the small-tooth-difference planetary speed-reduction mechanism satisfy a relational equation, so that the first outer teeth (11) form a motion trajectory M without cusps; and obtaining a tooth shape function of the first inner teeth (
