The calculation and explanatory note to the course project "Design and study of air two-stage compressor mechanisms" contains 47 pages of typewritten text .

The calculation and explanatory note contains the Design and study of the mechanism of a two-stage air compressor, determining the existing power factors based on the law of its movement, calculating the power factors acting in the kinematic pairs of the mechanism taking into account the geometry of the masses of the links; calculation and study of cam mechanism, gear box; and procedure for calculation of involute gearing and reduction gear .

Design of the main mechanism and definition of the law of its movement

The calculation is made in order to determine the main dimensions of the crank-shaft mechanism, to determine the moment of inertia of the fly masses providing the given travel irregularity. Use the system modeling method with a single-mass model. Engine crankshaft (crank 1) is taken as drive link.
