Abstract: A flexible-drive overrunning alternator pulley includes a shaft that includes a flange disposed at a first end of the shaft; an axle extending from a first side of the flange to a second end of the shaft; a shaft sleeve that includes first splines that include one or more teeth; a spring that includes a first end and a second end; and a bearing that includes: an inner bore extending through the bearing; an upper portion of the bearing including second splines that include one or more teeth; a middle portion of the bearing that includes a roller, wherein the roller is adapted to engage the upper portion of the bearing; and a lower portion of the bearing that includes a chamber adapted to receive a portion of the roller of the middle portion.

Abstract: A tensioner for reducing vibration and noise associated with a vehicle engine includes: a tensioner arm having a cylindrical protrusion extending from a first side of the tensioner arm; the cylindrical protrusion having at least one counter-bore disposed on a surface of the cylindrical protrusion and an inner bore extending through the cylindrical protrusion; an axle adapted to be received by the inner bore, the tensioner arm being adapted to rotate about the axle; a spring disposed proximate a second side of the tensioner arm, opposite the first side, the spring being adapted to bias the tensioner arm in a first direction; and a damping structure that includes a gripping seat adapted to engage a portion of the tensioner arm, in which the damping structure limits rotation of the tensioner arm in a second direction opposite the first direction.

Abstract: An overrunning alternator pulley includes: a shaft including a flange disposed at a first end of the shaft, an axle extending from a first side of the flange to a second end of the shaft, the second end of the shaft being opposed to the first end of the shaft, first splines including one or more teeth, the one or more teeth being disposed on the axle proximate to the flange, a pulley including an inner bore extending through the pulley, and a bearing adapted to engage the first splines, in which the bearing transmits torque when a relative rotation between the pulley and the shaft is in a first direction, and the bearing overruns when the relative rotation between the pulley and the shaft is in a second direction opposite to the first direction.
