Claims11
A method of manufacture of a power end frame of a reciprocating pump, comprising:
- aligning a plurality of rings with one another to define an interior of the power end frame configured to enclose a portion of a crankshaft of a power end of the reciprocating pump, wherein each ring, including a first ring and a second ring, of the plurality of rings comprises a flange, and aligning the plurality of rings with one another provides a space between the flange of the first ring of the plurality of rings and the flange of the second ring of the plurality of rings;
- positioning a sleeve within the space between the flange of the first ring and the flange of the second ring;
- inserting a rod through the plurality of rings;
- and
- securing the plurality of rings together with the rod such that the sleeve abuts the flange of the first ring and the flange of the second ring.
