Abstract

The invention provides a joint of a mechanical arm, and belongs to the technical field of machinery. The joint solves the problem that the joint of an existing mechanical arm is large in size. The joint of the mechanical arm comprises a shell, a motor and a harmonic reducer, wherein the motor and the harmonic reducer are integrated in the shell; the inner end of a rotating shaft of the motor is connected with the input end of the harmonic reducer; the output end of the harmonic reducer is connected with an output shaft; the rotating shaft of the motor is hollow; the inner end of the output shaft is fixed with the output end of the harmonic reducer, and the outer end of the output shaft penetrates through the outer end of the rotating shaft of the motor; a motor raster is fixed at the outer end of the rotating shaft of the motor; an output shaft raster is fixed at the outer end of the output shaft; an encoder is fixed in the shell; the output shaft raster and the motor raster are respectively positioned on the upper side and the lower side of the encoder; optoelectronic switches matched with output shaft raster and the motor raster are respectively arranged on the upper side and the lower side of the encoder. The joint has the advantages of small size, high space utilization rate, long service life and the like.

Description
