Power delivery devices for reciprocating engines, pumps, and compressors, and related systems and methods

A drive mechanism for generating a rotational motion output from a reciprocating motion input of an assembly of a reciprocating device and/or for generating reciprocating motion output from a rotational motion input, the drive mechanism comprising:

• an axially translating y-axis component configured to reciprocate substantially along a y-axis with the reciprocating motion of the assembly of the reciprocating device relative to a base to which the y-axis component is attached;
• an x-axis component slidingly coupled to and translating with the y-axis component substantially along the y-axis, the x-axis component being:
• i) configured to reciprocate substantially perpendicularly to the y-axis relative to the y-axis component, ii) comprising an orbital output component, and iii) comprising an orbital linking component disposed substantially concentric with the orbital output component;
• and
• a stationary output component rotatably attached to the base in a direction that is substantially perpendicular to both the x-axis and the y-axis, the stationary output engaging with the orbital output component of the x-axis component via a first integral interconnecting link, and
• a stationary linking component rotatably attached to the base in a direction that is substantially concentric with the stationary output component, the stationary linking component interfacing and rotatably engaging with the orbital linking component of the x-axis component via a second integral interconnecting link.

A method of converting an axial force from a reciprocating motion input of a reciprocating element to a torque applied to an output shaft assembly and/or converting a torque applied from the output shaft assembly to an axial force to the reciprocating motion of the reciprocating element, the method comprising:

• applying an axial force to move an axially translating y-axis component configured to reciprocate along a y-axis with the reciprocating motion input of a piston assembly relative to a base to which the y-axis component is slidingly attached;
• transmitting the axial force through an x-axis component which is slidingly coupled to and translating with the y-axis component substantially along the y-axis, the x-axis component being:
• i) configured to reciprocate substantially perpendicularly to the y-axis relative to the y-axis component, ii) comprising an orbital output component;
• transmitting the axial force from the x-axis component to the output shaft assembly via a first interconnecting link integral to the output shaft and rotatably connected to the orbital output component of the x-axis component, transmitting consistently applied torque and vice versa.
