Abstract
A power end includes a monolithic core with a base having a surface configured to mount to a fluid end of the reciprocating pump and a plurality of extensions integral to the base. Each extension of the plurality of extensions includes a ring portion that defines an opening configured to receive a crankshaft of the reciprocating pump. The power end also includes a plurality of plates separate from the monolithic core. Each plate of the plurality of plates extends between a pair of adjacent of extensions of the plurality of extensions to enclose the monolithic core.
Claims20
A power end for a reciprocating pump, the power end comprising:
- a monolithic core comprising:
- a base comprising a surface configured to mount to a fluid end of the reciprocating pump and a plurality of ribs offset from one another along an axis and having a first opening configured to receive a pinion shaft of the reciprocating pump;
- and
- a plurality of extensions, wherein each extension of the plurality of extensions extends from a respective rib of the plurality of ribs and is integral to the base, wherein each extension of the plurality of extensions comprises a ring portion that defines a second opening configured to receive a crankshaft of the reciprocating pump;
- and
- a plurality of plates separate from the monolithic core, wherein each plate of the plurality of plates extends between a pair of adjacent of extensions of the plurality of extensions to enclose the monolithic core.
A power end core for a power end of a reciprocating pump, the power end core comprising:
- a base comprising a surface and a plurality of ribs offset from one another along an axis, wherein each rib of the plurality of ribs comprises a first opening configured to receive a pinion shaft;
- a plurality of extensions integral with the base, wherein each extension of the plurality of extensions extends from a respective rib of the plurality of ribs, and each extension of the plurality of extensions defines a second opening configured to receive a crankshaft of the reciprocating pump such that the pinion shaft facilitates movement of the crankshaft;
- and
- a plurality of apertures formed into the surface of the base for mounting the base to a fluid end of the reciprocating pump, wherein each aperture of the plurality of apertures is formed through the respective rib of the plurality of ribs.
A power end for a reciprocating pump, the power end comprising:
- a base comprising a plurality of ribs offset from one another along an axis, wherein each rib of the plurality of ribs includes a first opening configured to receive a pinion shaft;
- a plurality of extensions integral with the base, wherein each extension of the plurality of extensions extends from a respective rib of the plurality of ribs such that extensions of the plurality of extensions are offset from one another along the axis, and each extension of the plurality of extensions defines a second opening configured to receive a crankshaft of the reciprocating pump;
- a plurality of frames separate from the base and from the plurality of extensions, wherein each frame of the plurality of frames is coupled to the respective rib of the plurality of ribs;
- a base plate configured to couple to an end of the base;
- an enclosure coupled to the base plate and defining a space configured to receive the crankshaft of the reciprocating pump;
- a pinion gear configured to couple to the pinion shaft in the space defined by the enclosure;
- and
- a bull gear configured to couple to the crankshaft in the space defined by the enclosure, wherein the bull gear is configured to engage with the pinion gear such that rotation of the pinion gear via rotation of the pinion shaft drives rotation of the bull gear and of the crankshaft.
