Description

In the course design, a double-acting piston pump was designed. The explanatory note contains:· design of the main mechanism of the double-acting piston pump, investigated its movement, calculation of the additional fly mass;· kinetostatic power calculation of the main lever mechanism;· design of the cylindrical involute gear train;· design of a two-row planetary gear with mixed engagement;· design of a cam mechanism with a translational moving pusher. The explanatory note to the course project "Design and study of mechanisms of a double-acting piston pump" contains 34 pages of typewritten text, 2 annexes.
