Flange-bolts with pinhole fit are used for connecting crosshead to extension rod. This rigid connection ensures the concentricity of extension rod andcrosshead. Coupling is used for connecting extension rod to crosshead. Light coupling enables the extension rod and the crosshead to connect to each otherwith ease and reliableness.

3. Pinion Shaft:

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

When assembly, the herring bone 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 crankshaftvia single row cylindrical roller bearings. Small ends are mounted on crossheadpin via double row cylindrical roller bearing. Double row radial spherical roller bearings are mounted at either end of the crankshaft.
