The invention provides a centrosymmetric single-stage undercut cycloid oscillating tooth speed reducer. The centrosymmetric single-stage undercut cycloid oscillating tooth speed reducer comprises an input shaft, a tapered roller bearing, a first crossed roller bearing, a constant-speed output shaft and the like. On the basis of a traditional cycloid steel ball oscillating tooth transmission technology, steel ball oscillating teeth with larger sizes are adopted, so that a cycloid raceway is undercut, and then an undercut cycloid steel ball oscillating tooth transmission unit is obtained; in order to ensure the accuracy and continuity of transmission, the steel ball oscillating teeth with proper sizes should be selected, so that only single side of the obtained undercut cycloid oscillating tooth raceway is undercut, the other side is not undercut, the portion, on the side which is not undercut, of the raceway ensures the accuracy and continuity of transmission, the portion, on the side which is undercut, of the
