A Method for Equivalent Analysis of Chain Transmission

To improve performances of chain transmission, a crank slide-way mechanism with path restrictions, which is equivalent to a chain transmission mechanism is introduced. A complex output path can be realized when kinematical curves with special shapes have been accepted. An equivalent analysis method of chain transmission is put forward in the paper. The kinematics and dynamics mathematical models based on closed loop vector equations and Newtonian mechanics principles are established in terms of structural forms and characteristics of the crank slide-way mechanism. Driving moments and restrained forces at different positions in one period have been indicated in the case of simulation to a real structure. Compared to the existing discrete point analysis, the method is very feasible and efficient due to its characteristics such that strict solve progress, less workload and high precision. It provides a useful feasible measurement for carrying out kinematics and dynamics characteristics of mechanisms like this; similarly it can be applied to other kinds of relevant rod mechanisms.
