Double-degree-of-freedom robot shoulder joint steering engine

The invention relates to a double-degree-of-freedom robot shoulder joint steering engine. Mostly, the existing robot shoulder joint steering engine is single-shaft output, namely only one degree of freedom can be provided for a robot. The double-degree-of-freedom robot shoulder joint steering engine comprises an end cover and a shell. The end cover and the shell are connected through a screw to form a sealed space. The sealed space is internally provided with motors, a motor gear, a speed-reducing mechanism, a bearing, a control circuit board and an angle sensor. The motor gear is engaged with an input gear of the speed-reducing mechanism and an output shaft of the speed-reducing mechanism outputs power. The angle sensor is arranged on the output shaft. According to the double-degree-of-freedom robot shoulder joint steering engine, the two motors are arranged in the same sealed space. and the power is output in two directions at the same time through the gear speed-reducing mechanism arranged in the shell; and the control circuit board and the angle sensor, which are arranged at the inner part, can respectively control the output angles at the two directions, so that the robot shoulder joint steering engine has the capability of providing two degrees of freedom.
