【Abstract】 According to the geometric relationship among the crankshaft, connecting rod, crosshead and piston of a horizontal reciprocating compressor, based on the force and motion analysis, the method for measuring the concentricity between the crosshead and the piston was described, and different methods for calculating the eccentricities of the right and left crossheads were offered according to their different running states. An example of calculation and measurement was given, and satisfactory results were obtained.更多还原
