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
ATO 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.
