The zero-backlash robot speed reducer comprises a speed reducer shell, a motor assembly and a gear assembly which are in transmission connection are arranged in the speed reducer shell, and a telescopic component is arranged between the opposite end faces of the motor assembly and the gear assembly; the gear assembly is a planetary gear mechanism and comprises a conical sun gear, a conical planetary gear and a conical inner gear ring which are meshed with one another; the planetary gear mechanism takes one side of the common small-diameter end of the conical inner gear ring and the conical planetary gear as an output direction; the conical sun gear is coaxially connected to the power output end of the motor assembly. The speed reducing mechanism can automatically eliminate backlash after the gears are abraded, enables meshing between the gears to be kept consistent all the time, can guarantee stable output performance of the speed reducing mechanism, and is compact in structure and high in transmission effici
