One or more embodiments of modular crankshafts may also include individual connecting rod journals that are attached to individual main bearing journals using a plurality of fasteners.
Claims17
An apparatus, comprising:
- a crankshaft, comprising:
- a first main bearing journal positioned in a side-by-side relationship with a second main bearing journal, the first and second main bearing journals each comprising:
- a cylindrical body with opposed first and second sides;
- a first connection element on the first side;
- and
- a second connection element on the second side;
- a rod journal having opposed first and second sides connected by an exterior surface, the first side having an opening configured to receive the first connection element of the first main bearing journal and the second side having an opening configured to receive the second connection element of the second main bearing journal, wherein the first opening and second opening are connected by a through-passage;
- and
- a fastener installed in the through-passage of the rod journal, the fastener having first and second threaded ends, each of the first and second threaded ends being configured for threaded connection to a selected one of the first and second connection element.
