Abstract
Crankshaft and connecting rod assemblies for hydraulic fracturing pumps and related methods may enhance the flow of fracturing fluid into a wellhead during a high-pressure fracturing operation. The assemblies and methods may include a crankshaft having a crankpin between first and second journals. The crankpin may include first and second longitudinally spaced ridges at least partially extending circumferentially around the crankpin. The assemblies and methods further may include first and second connecting rods connected to the crankpin. The first connecting rod may include first and second crankpin connectors connected to the crankpin and at least partially defining therebetween a connecting rod clearance between and positioned to at least partially receive therein an end of a second connecting rod. The assemblies and methods also may include first and second rod clamps connected to the first crankpin connector, thereby to rotatably connect the first and second connecting rods to the crankpin.
