Abstract
A dynamically vented crankshaft seal and systems and methods thereof can include a seal assembly comprised of a wear sleeve; a main seal; a dust seal; and a plurality of vents circumferentially spaced from each other. Each of the vents can be formed by at least a channel. The channel may be formed in or by the wear sleeve, which can be a primary wear sleeve or a secondary wear sleeve. Further, each of the vents can extend from a first side of the seal assembly to between the main seal and the dust seal. An angle between a channel length axis of the channel and a trajectory of circumferential motion can be ninety degrees, acute, or obtuse for each of the channels.
