  • Patent number: 11391189
    Abstract: A link component (150) with an oil hole (150E) is attached to a crankshaft (106) of an internal combustion engine (E), and the oil hole (150E) allows communication from an outside to the crankshaft (106) side. The oil hole (150E) has an inclined surface (150F) along an opening rim on the crankshaft (106) side. A surface other than the oil hole (150E) has a carbon concentration of 0.5 wt % or more. The inclined surface (150F) has a carbon concentration within a range of 0.7 wt % or more and 0.9 wt % or less. Production cost is suppressed, and at the same time, damage is prevented by increasing resistance of the oil-hole part on which stress is liable to concentrate.

  • Patent number: 9133932
    Abstract: Reciprocating motion can be converted to rotary motion through a crankshaft and a connecting rod. In a connecting rod that is primarily in compression, two opposing connecting rods can be coupled to a single journal. Two bearing shell portions are placed over the journal with a pushrod placed over each bearing shell portion. The pushrods are normally in compression. To overcome the potentiality of the pushrods briefly being in tension, retainers can be coupled to the pushrods. Because both pushrods are coupled in-line, the width of the journal that can accommodate these pushrods is shorter than for a journal on which the two pushrods are side by side. The crankshaft can be shorter, stronger, and lighter weight.

  • Patent number: 7331548
    Abstract: Systems and methods for implementing control linkages that may be employed to produce synchronous motion in two adjacent controlled devices controlled by a common input. In one example implementation, a semi-rigid modified constant velocity (CV) joint control linkage may be provided that is laterally self-stabilizing. The modified constant velocity CV joint control linkage may include an input push rod assembly that is self-aligning, deflectable and of an adjustable length. The CV joint may be configured with a central cage that is allowed to skew to allow for alignment of the controlled devices.

  • Patent number: 4236416
    Abstract: A power transmission for engines, motors, pumps and the like comprises a power shaft mounted to rotate about a fixed axis, an eccentric in the form of a tapered bar having arcuate ends secured on the power shaft to turn therewith, a power transmission ring having a circular internal bearing surface contacting the arcuate ends of the eccentric, a plurality of cranks connected to the power transmission ring by crankpins, each crank having a crankshaft journaled to turn about a fixed axis which is parallel to the power shaft. Power may be applied to any of the crankshafts by a motor coupled to the crankshaft or power may be applied to any crankpin by a pitman connecting the piston of an internal combustion engine or fluid motor to the crankpin. In either case, the power applied imparts non-rotary, planetary motion to the power transmission ring to turn the eccentric about the axis of the power shaft, thereby rotating the power shaft at the same speed at which each of the cranks is rotated but with more torque.

  • Patent number: 4194404
    Abstract: A crank assembly for coupling a plurality of connecting rods to a common crank pin of a crankshaft includes an articulation member journaled on the crank pin. The articulation member carries a plurality of knuckle pins arranged in a radial array about the crank pin. Auxiliary cranks interconnect the articulation member and the body of the machine to limit freedom of movement of the articulation member and to assure that it does not rotate in space as it moves with the crank pin in a circular path around the axis of the crankshaft. The described assembly is particularly useful with reciprocating piston machines of the type having a radial array of cylinders with pistons movable in the cylinders, and permits the use of identical connecting rods, each drivingly connecting a separate one of the knuckle pins and a separate one of the pistons. Moreover, each of the auxiliary cranks can be used either as an additional power transmission input or output for the system.
