What is a crosshead bearing?

n. a sliding member of a reciprocating engine for keeping the motion of the joint between a piston rod and a connecting rod in a straight line.

What is a steam engine crosshead?

English: The crosshead of a steam engine is the sliding bearing used to support the sideways forces from the connecting rod without placing this sideways load onto the piston or piston rod seals. Trunk pistons, as used in some steam engines and most internal combustion engines, do not have a separate crosshead.

Where is the crosshead bearing located?

The main function of the crosshead bearing of a crosshead engine is to transmit the load from the connecting rod, which is directly attached to the piston of the engine, through a second rod to the guide shoe, which bears the entire crosshead.

What are the parts in cross head *?

Crosshead Piston: Comprises of Piston crown, Piston skirt and piston rod(used in large two stroke engine) which is connected to crosshead functioning to transfer the side thrust to the engine structure.

How does the crosshead work?

A crosshead is a mechanism used as part of the slider-crank linkages of long reciprocating engines and reciprocating compressors to eliminate sideways pressure on the piston. Also, the crosshead enables the connecting rod to freely move outside the cylinder.

What is crosshead guide?

A guide for making the crosshead of an engine move in a parallel line with the cylinder axis.

How does the crosshead engine works?

How is crosshead lubricated?

The crosshead on a slow speed 2 stroke is a difficult bearing to lubricate effectively. Instead the lubrication starts as boundary, and as the rubbing speed increases, a hydrodynamic film is built up. As the rubbing speed decreases the lubrication becomes boundary once again.

What is crosshead pin?

The Pin crosshead is steel material, harden ground & hollow inside for proper oil pressure of unit.

What is the another name of Cross head?

Which two rods are connected by a cross head?

The piston rod 2 is secured to the crosshead block by means of the cotter 5. Crosshead is used in horizontal steam engines for connecting the piston rod and connecting rod.

How do you check crosshead bearing clearance?

16) Check the bearing clearance by inserting feeler gauge b/w bearing cap and crosshead journal exactly next to the landing surface of the piston rod foot. 18) Turn the crankshaft down enough to give access to nuts and screws on piston rod.
