Cross Head十字头
All industrial compressors are equipped with crosshead. The crosshead is used to
guide the piston in the cylinder bore. The following are the advantage of the crosshead.

Bearing
The main and connecting rod bearings should be split-sleeve, steel-backed, babbitted
insert type. Antifriction bearing shall be used for compressor rating less than
150kW. As per API-618 trapper roller bearings are used as the main bearing for
compressor rating less than 150kW.

Tangent Ring切线环
The tangent ring is cut into three segments so that each cut lies on the side of an
equilateral triangle. The cuts of this ring maintain sealing contact regardless of
variations of the ring’s inside diameter. If wear occurs in the tangent ring, the
garter spring will tighten the ring segments to compensate for the wear.

The Figure shows a drilled crankshaft.
Crankshafts should have removable balance weights to compensate the rotary unbalance
as well as reciprocating unbalances. The crankshaft should be dynamically balanced
when above 800 rpm.
Distance piece may be furnished as single, double, or extra-long type.
The purpose of longer distance piece is to prevent the lubricant entering from crankcase to cylinder. Thereby preventing the gas contamination due to lubrication entering in the cylinder side.
