Abstract
A reciprocating pump drive is disclosed. The reciprocating pump drive comprises a housing and a transmission mechanism. The transmission mechanism comprising an input shaft rotatably supported in the housing. The input shaft has an input shaft axis. An intermediate shaft is rotatably supported in the housing and coupled to the input shaft. The intermediate shaft has an intermediate shaft axis wherein the input shaft axis is parallel to the intermediate shaft axis. A gear assembly is coupled to the intermediate shaft. An output shaft is coupled to the gear assembly. The output shaft has an output shaft axis wherein the intermediate shaft axis is coaxially aligned to the output shaft axis.
