Abstract
A conjugate drive mechanism of a motion converter includes a conjugate driver, which is rotatably mounted on a crankpin, and a bearing conjugate, which is mounted on a linearly movable shuttle. The conjugate drive mechanism is lubricated by supplying lubricating fluid from a pressurized source to an interface between trackable profiles of the bearing conjugate and the conjugate driver. The trackable profiles, which are in continuous conjugating engagement, have equal circumferential lengths.
Claims47
A lubrication system for a conjugate drive mechanism of a scotch yoke type motion converter, comprising a linearly movable shuttle;
- a crankpin positioned within an aperture in said shuttle and rotatable in a circular path;
- a bearing conjugate having a trackable profile, which forms a portion of a peripheral boundary of said aperture and which has a first circumferential length;
- a conjugate driver positioned within said aperture and rotatably mounted about said crankpin, at least a portion of said conjugate driver being located between said crankpin and said bearing conjugate and having a tracking profile, which has a second circumferential length equal to said first circumferential length, said tracking profile and said trackable profile engaging each other continuously in conjugation as said crankpin rotates such that motion is transferable between said crankpin and said shuttle;
- and conveying means for conveying lubricating fluid from a source of pressurized lubricating fluid to an interface between said tracking profile and said trackable profile.
