Crosshead

Crosshead and crosshead guide are made of ASTM A48-83meehanite featuring good abrasion resistance and long service life. Besides F-500 mud pump that is cylindrical structure, upper and lower guide structures are used for other mud pumps, so that the concentricity can be adjusted by adding space under the lower guide. Flange-bolts with pinhole fit are used for connecting crosshead to extension rod. This rigid connection ensures the concentricity of extension rod and crosshead. Coupling is used for connecting extension rod to crosshead. Light coupling enables the extension rod and the crosshead to connect to each other with ease and reliableness.

Pinion Shaft

Pinion shaft is made of forged alloy steel, on which a herringbone gear with the medium-hard teeth surface is machined. For easy maintenance, single row radical cylindrical roller bearing with double ribbed outer ring is used. The pinion shaft ends are prolonged so that sheave or sprocket can be mounted on either end.

Crankshaft

Eastland brand crankshaft is made of casted alloy steel. Eccentric ring gear, connection rod and bearing are mounted on it. The eccentric ring gear is herringbone. When assembly, the herringbone bore and crankshaft are of interference fit and fastened with bolts and lock nuts. Big ends of connection rod are mounted on three eccentric straps of the crankshaft via single row cylindrical roller bearings. Small ends are mounted on crosshead pin via double row cylindrical roller bearing. Double row radial spherical roller bearings are mounted at either end of the crankshaft.
