  • Multi-piece pinion shaft assembly
    Patent number: 11859664
    Abstract: A pinion shaft assembly for operation in a power end of a reciprocating pump includes a tubular member coupled to first pinion gear member via an interference coupling extension, possibly having a protruding alignment key operable to engage a slot formed on an inner wall of the first end of the tubular member to ensure correct rotational orientation of the first pinion gear member and the tubular member and to help prevent rotation of the first pinion gear member relative to the tubular member. The tubular member is also coupled to a second pinion gear member via an interference coupling extension, possibly having a protruding alignment key operable to engage a slot formed on an inner wall of the second end of the tubular member to ensure correct rotational orientation of the second pinion gear member and the tubular member and to help prevent rotation of the second pinion gear member relative to the tubular member.
    Type: Grant
