The utility model discloses a drum-shaped roller type coupler which comprises a shaft sleeve with drum-shaped outer teeth, and an inner gear ring meshed with the shaft sleeve, wherein a roller used for transmitting a torque is arranged between the shaft sleeve and the inner gear ring; the roller is positioned in a hole formed by two corresponding inner concave cambered surfaces between meshing pairs of the drum-shaped outer teeth and inner ring teeth of the inner gear ring; the roller is capable of transmitting a larger torque, ensures that the processing precision requirement of the drum-shaped outer teeth and the inner ring teeth of the inner gear ring is greatly reduced, and can be processed with a common machine tool without a special processing device; cambered surfaces are arranged on roots of the drum-shaped outer teeth of the shaft sleeve and the inner ring teeth of the inner gear ring, even though the roller is damaged due to fatigue in a running process, the torque is transmitted between the shaft s
