摘要： Provided is a crossbow cam comprising: a first cam axis; a second cam axis parallel to and offset from the first cam axis; a first power cord channel extending from the first surface along a first helical path having a first helix axis coincident with the first cam axis; and a second power cord channel extending from the second surface along a second helical path having a second helix axis coincident with first cam axis. The crossbow cam may further comprise a plate normal to the first cam axis, and defining a first plane therethrough, the plate having a first surface, a second surface opposite the first surface, and a perimeter surface extending between the first surface and the second surface, the perimeter surface defined by a bowstring channel extending around the first cam axis to define a path of varying radius about the first cam axis.
