Zusammenfassung:	The utility model belongs to the technical field of rotary speed reducers. The idle stroke-free planetary rotary speed reducer comprises an input shaft, a planetary transmission assembly and an outputshaft, the input shaft is in transmission connection with a sun gear or a planetary carrier of the planetary transmission assembly, a gear ring of the planetary transmission assembly is fixed, and the other rotating part of the planetary transmission assembly is in transmission connection with the output shaft; a friction brake assembly I is arranged between the input shaft and the brake shell, and when no hydraulic oil is input into the brake oil port a, the piston I tightly presses the friction brake assembly I under the action of the spring I to brake the input shaft; a friction brake assembly II is arranged between the output shaft and the bearing seat, and when hydraulic oil is input into the brake oil port b, the piston II overcomes the resistance of the spring II under the pressureeffect of the hydraulic o
