What is a cross head of a steam engine?
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.
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 crosshead guide?
A guide for making the crosshead of an engine move in a parallel line with the cylinder axis.
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 is the another name of Cross head?
heading, header, head.
Which joints are used for connecting piston rod and cross head of engine?
Cotter’s joint is widely used to connect the piston rod and crosshead of a steam engine, as a joint between the piston rod crosshead, and the tailor pump rod, foundation bolt, etc.
What is the purpose of cross head?
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.
What is a cross head pin?
A piston rod is attached to the piston and links it to the crosshead, which is a large casting sliding in crosshead guides (UK: slidebar), allowing it only to move in the same direction as the piston travel. The crosshead also houses the gudgeon pin (US: wristpin) on which the small end of the connecting rod pivots.
Why crosshead lubrication is difficult?
The crosshead on a slow speed 2 stroke is a difficult bearing to lubricate effectively. The load is continually downward and because the con rod swings about the pin, changing direction each stroke, true hydrodynamic lubrication cannot take place.
What does a cross head do?
What does Crossing heads mean?
(also cross heading) A heading to a paragraph printed across a column in the body of a newspaper article.
Which two rods are connected by a cross head?
What is the function of the crosshead on a steam locomotive?
Typical steam locomotive; crosshead and two slide bars 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 the function of a crosshead in a reciprocating engine?
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 the function of the crosshead bearing on a diesel engine?
Large diesels often have a plunger oilpump directly attached to the crosshead to supply oil under high pressure to the crosshead bearing. In the case of the steam engine, a crosshead is essential if the engine is to be double acting – steam is applied to both sides of the piston, which requires a seal around the piston rod.
What is a piston rod and crosshead?
A piston rod is attached to the piston and links it to the crosshead, which is a large casting sliding in crosshead guides (UK: slidebar ), allowing it only to move in the same direction as the piston travel. The crosshead also houses the gudgeon pin (US: wristpin) on which the small end of the connecting rod pivots.
