Quadrature transmission;  intermittent mechanisms;  Groove wheel mechanism

For the problem of orthogonal continuous transmission encountered in the mechanical system, the groove wheel mechanism is used to design, which overcomes the cargo interference and extrusion phenomenon that is easy to occur in the general design, so that the designed orthogonal transmission mechanism has better transmission accuracy and motion stability. The mechanism is mainly composed of two parts: hoist and cargo machine. By adjusting the moving-stop ratio of the grooved wheel mechanism, the lifting movement and horizontal movement of the cargo can be carried out continuously. Its design features are simple structure, high transmission accuracy and economic practicality.
