Keywords: Slipper guide crosshead (Heat Engines, 1913).jpg A Crosshead of the slipper or shoe guide form as used on some stationary engines The crosshead supports the end of the piston rod outside the cylinder where the connecting rod little end is attached Its function is to resist the transverse forces vertical here from the angle connecting rod against the horizontal piston rod The direction of these forces predominently depends on the direction of rotation For stationary engines that only run in one direction the crosshead may be arranged so that the majority of the force is downwards and so taken on the larger surface of the crosshead and guide bar This requires the engine to run over where the top of the flywheel always moves away from the cylinder Steam engines with slipper crossheads Steam engine crossheads |
