Analysis of Linkage Mechanisms with Internal Driving Link

摘要

The linkage mechanisms with internal driving link that are used in many different machines are considered in thepaper. The mechanism contains hydraulic cylinder that is hinged to the rack, a rocker arm that is pivotally attachedto the driving rod and to the rack. The law of motion of a rod in a hydraulic cylinder was synthesized. The posi-tions, angular velocities and accelerations of the hydraulic cylinder and the rocker arm are analytically determinedby the methods of engineering mechanics and the theory of mechanisms and machines. Thus, brief analyticaldependencies are obtained. It is shown that the angular accelerations of the hydraulic cylinder and the rocker armare qualitatively similar to the relative acceleration of the rod. The results of the work can be used in the motionresearch of hydraulically driven excavator buckets, other lifting and loading, road building machines, in the actuat-ing mechanisms of industrial robots.
