Force on the crosshead and reverse angle
Thread Content
”It is necessary to consider the direction of rotation of the crankshaft; assuming that, when viewed from the motor side, it rotates clockwise, with force acting on the right side at the lower position and on the left side at the upper position. As shown in the diagram, when the crankshaft reaches a position below the center line, does the crosshead experience an upward force, which in turn causes stress on its upper contact surface? Therefore, both contact surfaces of the crosshead are considered working surfaces.
As shown in the figure, when the crankshaft moves to a position below the centerline, the crosshead still experiences a downward force
Hello, could you draw the force direction on the compressor? If the crankshaft rotates in the opposite direction, is the force applied in the opposite direction as well? Thank you
According to the direction of rotation, the diagram shows the right-side cylinder as viewed from the motor side; the crosshead is always under downward force. Even when it is in a position below the center line, it is necessary to understand on your own that when the piston moves forward, the crosshead experiences a downward push, while it experiences a downward pull when it is below the center line
