摘要： A tensioning system including a base and an arm pivotally coupled to the base, the arm having an engagement surface and being configured to pivot relative to the base about a pivot axis. The system further includes a biasing mechanism operatively coupled to the arm to bias the arm relative to the base, and a seal assembly sealingly positioned between the arm and the base. The seal assembly is coaxial with the pivot axis and configured to accommodate relative axial movement between the base and the arm and relative radial movement between the base and the arm while still maintaining a seal therebetween.

摘要： A tensioner may be part of a power system to tension an endless power transmitting element. The tensioner includes an arm having an arm arbor with a slot therethrough that is rotatable about a first axis, a bushing having a sleeve that includes a cut-out and a removable sleeve-segment that has a protrusion thereon, the sleeve-segment being receivable in the cut-out with the protrusion in the slot, and a spring coupled to the arm for rotation of the arm about the first axis into tensioning engagement with a power transmitting element. The spring is positioned where it can radially expand into contact with the protrusion of the bushing, at least the protrusion on the sleeve-segment, as the arm is rotated in a direction opposite the direction of tensioning engagement such that the bushing is urged radially outward relative to the arm arbor to provide frictional damping.

摘要： A pulley assembly for use in an automobile accessory drive system includes a shaft engaging hub, a pulley member, a nut treaded onto the shaft engaging hub, and a brake member interposed between the pulley member and the nut. The shaft engaging hub is engaged with an accessory input shaft for rotation therewith. Frictional engagement between the pulley member, the brake member, and the nut transfers torque from the pulley member to the input shaft. The pulley member includes an inner coupling surface and a peripheral belt-engaging surface. The nut includes an outer coupling surface. The brake member includes a first coupling surface in frictional engagement the outer coupling surface of the nut and a second coupling surface in frictional engagement with the inner coupling surface of the pulley member. When torque is applied to the nut in a first direction the out coupling surface of the nut couples to the inner coupling surface of the brake member such that the hub and the nut rotate with the pulley member. The outer coupling surface of the nut and the inner coupling surface of the brake member decouple when torque applied to the nut is in a second direction opposite the first direction such that the hub rotates relative to the pulley member.

摘要： Disclosed is a pulley assembly including a pulley having an axis of rotation a pulley shell, and a bearing; a shaft having a pulley-receiving end that receives the pulley; and a first bearing shield disposed at the pulley-receiving end of the shaft. The pulley shell includes an annular wall that defines an opening for housing the bearing. The bearing is housed therein and has an inner race, outer race, and a rolling element. The first bearing shield includes a deflected sealing member biases against at least one of the outer race of the bearing and the pulley shell as a first contact seal to protect the bearing from contaminants.

摘要： A pulley assembly for an automobile accessory drive system includes a shaft engaging hub, a nut threaded onto the shaft engaging hub, an annular bushing, and one or more brake shoes positioned around the outside of the annular bushing all housed with a pulley member. The nut is capable of axial translation relative to the annular bushing and the annular bushing is capable of expanding radially outward in response to the axial translation of the nut in a first direction to provide frictional engagement between the inner coupling surface of the pulley member and the outer coupling surface of the brake shoes, which transfers torque from the pulley member to the input shaft. The nut includes a generally frustoconical outer surface, opposite its inner threaded surface, for seating the nut in the annular bushing.

摘要： A tensioner for an endless power transmitting element in a drive system is disclosed that includes an arm rotatable about an axis and having a sleeve that includes a ramp face or contoured face, a damper cup having a protrusion and a plate, a spring case that houses the sleeve of the arm and the damper cup with the damper cup's plate mated with the ramp face or contoured face of the sleeve. During wind-up of the tensioner, a normal force is applied to the damper cup's protrusion that moves the plate along the ramp face or contoured face in a first direction, and in the first direction the ramp face or contoured face pushes the damper cup generally radially outward into the spring case to provide frictional damping.
