IMPROVEMENT OF LINKAGE DRIVE PUMPING UNIT CONSTRUCTION
By means of vector algebra, kinematics analysis algorithm of spatial sixmembered linkage drive pumping unit model SK8 is developed. Authors obtain decision of system of vector equations, on the basis of which the effect of dynamic errors linkage to the position of its links is investigated. The elastic deformation of rods is detected, which is a consequence of the presence of redundant links in the mechanism. To eliminate elastic deformation of the units, design changes in the kinematic scheme of the lever mechanism are proposed.
