The new transmission mechanism crank-group driving mechanism is mainly used in some special light industrial machinery. Paper drew the mechanism's trajectory curve of the structure unit by a new way-the graphical method, analyzed it related to the trajectory function, and then studied the motion characteristics of the whole mechanism. The study shows that all the cranks' motion on the crank-group driving mechanism are synchronous and uniform at any time, the connecting rod truss composed of the parallel double crank mechanism is doing translation from beginning to the end. The conclusions are consistent with the previous research; it validated the correctness of the foregoing research, and then laid the theoretical foundation for the mechanisms widely used in future.

“…Driving crank and driven cranks have the same phase, structure and size, therefore, driving crank, any driven crank and the rod between them can be seen as a parallelogram mechanism. Under ideal conditions (no size error, no stress deformation, and no installation error), each crank doe's rotary movement around its own axis, and the rod does translational motion around its own center [3]. The redundant constraints are often transformed into statically indeterminate structure because of the errors and material deformation in processing and installation.…”

“…The redundant constraints are often transformed into statically indeterminate structure because of the errors and material deformation in processing and installation. The appropriate clearance fit between sizes of the crank pin and rod pin hole are selected to avoid statically indeterminate structure and ensure the feasibility of the mechanism motion [4]. But the mechanism's output parameters are adversely affected by the clearances.…”

Abstract-The crank-group driving mechanism includes a group of redundant constraints. This mechanism can move as a driving mechanism under ideal conditions, but it may be stuck because of the processing errors in practical applications. So, some clearances are reserved between the pin hole and the pin to ensure that the crank-group driving mechanism can achieve normal movement, but these clearances inevitably affect the dynamic performance of the output member. In this paper, the dynamic simulation model of the crank-group driving mechanism is established by NX/Motion Simulation which is based on the 3-D model of planar link mechanism. The comparative analysis is made about the dynamic characteristics of the mechanism which is influenced by different clearances, different angular velocity, different damping, and make a qualitative analysis how the clearances affects the dynamic performance of the output member. The simulation results also show that appropriately increasing the angular velocity, increasing stiffness and damping of the components can effectively inhibit the adverse influences of clearance on the dynamic characteristics of the mechanism.
