Problems solved by technology
[0003] When the transmission distance is long, the existing flexible cable transmission mechanism is mainly realized in the form of a transmission wheel, and its layout is extremely complicated, resulting in high manufacturing and maintenance costs of the system
When the motion is transmitted forward through the joint, the movement of the transmission wheel along with the joint will affect its transmission accuracy. Therefore, for a multi-joint series system, the drive motor is generally placed on the body, which makes the system more complex and lightweight. less than reflected

The invention relates to a force bearing hose-based flexible cable transmission mechanism, in particular to a mechanism that transfers motor movement by means of force bearing hoses and flexible cables. The force bearing hose-based flexible cable transmission mechanism comprises a driving wheel, a driven wheel, a motor encoder, a motor, a speed reducer, a driven wheel encoder, the force bearing hoses, the flexible cables and the like, wherein the driving wheel and the driven wheel are respectively provided with a wheel groove and are respectively mounted on a driving wheel mounting seat and adriven wheel mounting seat; two flexible cables are fixed to the driving wheel; the two flexible cables enter the force bearing hoses after passing through a force bearing hose baffle plate on one side of the driving wheel after winding in the wheel grooves in clockwise and counterclockwise directions; and the flexible cables wind in different directions and are fixed to the driven wheel after passing through a force bearing hose baffle plate on a driven wheel side. According to the force bearing hose-based flexible cable transmission mechanism, long-distance and large-corner forward transmission through a movement joint can be realized; meanwhile, smooth winding and reliable pre-tightening of the flexible cables are ensured; and the force bearing hose-based flexible cable transmission mechanism has the advantages of simple structure, flexible layout, low cost, high precision and high rigidity.
Description
technical field [0001] The invention relates to a flexible cable transmission mechanism, in particular to a flexible cable transmission mechanism based on a load-bearing hose. Background technique [0002] The flexible cable transmission mechanism is a mechanism that realizes flexible friction transmission through a transmission medium with proper preload between the driving and driven wheels. It has the characteristics of flexible layout, high precision, and light weight. And servo mechanism has been widely used. [0003] When the transmission distance is relatively long, the existing flexible cable transmission mechanism is mainly implemented in the form of a transmission wheel, and its layout is extremely complicated, resulting in high manufacturing and maintenance costs of the system. When the motion is transmitted forward through the joint, the movement of the transmission wheel along with the joint will affect its transmission accuracy. Therefore, for a multi-joint se...
