The crosshead is positioned within the cylinder and is attached to the piston by means of a crosshead guide. It moves back and forth in a straight line, transferring the force generated by the piston to the connecting rod, which then translates this motion into rotational movement of the crankshaft. This design helps to reduce side forces on the piston and cylinder walls, leading to smoother operation and extended equipment life.
Crossheads are typically made from high-strength materials such as cast iron, steel, or advanced alloys to withstand the significant mechanical stresses and pressures encountered during operation. They are often used in high-power engines and compressors where durability and reliability are essential.
In addition to engines and compressors, crossheads can also be found in various other mechanical systems where linear-to-rotary motion conversion is required. Proper maintenance and alignment of the crosshead are vital to ensure optimal performance and prevent mechanical failure.
