Kinematic Features of Operational Equipment Linkage in Single-bucket Excavators
The paper provides formulas for determining basic parameters which would characterize kinematic properties of two-crank operational equipment linkage via hoisting and thrusting transfer functions of the mechanism. It is known that the type of relations determining hoisting transfer functions--functional relation between velocities of output and input links of a mechanism--changes when a certain correlation between angular coordinates of the links is reached. A computing experiment was carried out, which focused on calculating operation parameters of the actuating mechanisms (velocities and forces of hoisting and thrusting) used in EKG-20A excavators made by JSC "Uralmashplant". Required correlations between velocities of working motions were determined, which are based on the condition of realizing a specified law of bucket motion (cutting edge motion). A form of graphical representation depicting working motion velocities as hodographs is proposed.
