The invention relates to a stay wire transmission mechanism of a mechanical arm and the mechanical arm. The stay wire transmission mechanism of the mechanical arm comprises a first motor, a first motor synchronous driving wheel, a middle wheel, an output wheel, a first stay wire and a second stay wire, and the first stay wire is wound on the first motor synchronous driving wheel and the middle wheel; and the second stay wire is wound on the middle wheel and the output wheel, the first motor synchronous driving wheel is installed on an output shaft of the first motor, the first motor drives the first motor synchronous driving wheel, the first motor synchronous driving wheel drives the middle wheel through the first stay wire, and the middle wheel drives the output wheel through the second stay wire. Joint motors of all joints are omitted, the weight of the mechanical arm is reduced, and the efficiency and flexibility of the mechanical arm are improved. The problems that a mechanical arm with a joint motor is high in weight, complex in structure and low in efficiency are solved.
Description
technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a cable transmission mechanism of a mechanical arm and a mechanical arm. Background technique [0002] The robotic arm is a common device in industrial production. It is an important part of industrial automation and can assist or replace technicians in heavy single work. Most of the current robotic arms use joint motors to drive the movement of each joint. Each joint needs a joint motor. The installation structure is complex and the weight is heavy. Most of the power of the motor is used to overcome the load brought by its own weight. , which reduces the ability and efficiency of the mechanical arm to do work externally. And as the weight of each joint increases, the stability and flexibility of the mechanical arm are further reduced. Contents of the invention [0003] The object of the present invention is to provide a pull wire transmission mechanism of a mechanica...
