Abstract
A power end frame of a reciprocating pump includes a plate and a ring configured to couple to the plate in an assembled configuration of the power end frame. The ring and the plate cooperatively define a compartment of an interior of the power end frame configured to enclose a crankshaft of the reciprocating pump, the ring includes a base surface and a flange extending from the base surface such that an interface surface of the flange is offset from the base surface, the base surface faces the compartment of the power end frame, and the interface surface is configured to abut the plate in the assembled configuration.
Claims20
A power end frame of a reciprocating pump, comprising:
- a plate;
- and
- a ring configured to couple to the plate in an assembled configuration of the power end frame, wherein the ring and the plate cooperatively define a compartment of an interior of the power end frame configured to enclose a portion of a crankshaft of a power end of the reciprocating pump, wherein the ring comprises a base surface and a flange, the base surface faces the compartment of the power end frame, and the flange comprises:
- an arcuate portion extending from the base surface;
- and
- an extended portion extending from the arcuate portion such that the ring is curved from the base surface to the extended portion, wherein an interior surface of the extended portion defines at least a portion of the compartment, an exterior surface of the extended portion is disposed opposite the interior surface, and the interior surface and the exterior surface are tapered toward one another to form an interface surface extending therebetween, and the interface surface is configured to abut the plate in the assembled configuration.
A method of manufacture of a power end frame of a reciprocating pump, comprising:
- providing a ring with a flange, wherein the ring comprises a base surface facing a compartment of the power end frame, the flange comprises an arcuate portion extending from the base surface, an extended portion comprising an interior surface defining at least a portion of the compartment and an exterior surface opposite the interior surface, an interface surface extending from the interior surface to the exterior surface, and the interior surface and the exterior surface extend obliquely toward one another to the interface surface to reduce a dimension of the interface surface;
- abutting the interface surface of the flange of the ring against a plate such that the plate is offset from the base surface of the ring;
- and
- applying a weld along the flange to penetrate the interface surface to secure the ring and the plate to one another.
A ring of a power end frame of a reciprocating pump, the ring comprising:
- a base surface;
- and
- a flange comprising:
- an arcuate portion extending from the base surface to form a recess positioned in a compartment of an interior of the power end frame;
- an extended portion extending from the arcuate portion, wherein the extended portion comprises an interior surface defining at least a portion of the compartment, and the extended portion comprises an exterior surface opposite the interior surface:
- and
- an interface surface at where the interior surface and the exterior surface meet, wherein the interface surface is configured to abut a plate of the power end frame, the interface surface is offset from the base surface via the flange, and the interior surface and the exterior surface are slanted toward one another to reduce a dimension of the interface surface, which enables a weld being applied at the flange to penetrate the interface surface to secure the ring to the plate.
