ABSTRACT:
A free-floating tensioning device having motion damping capabilities and gyroscopic action stabilizing capabilities for use in a drive system having a flexible drive element is disclosed. The tensioning device includes a tensioning assembly along with a damping member and/or a stabilizing member. The tensioning assembly has first and second tensioning members, each having a contact surface that contacts the drive elements, and a positioning component for securing the tensioning members a selected distance away from one another in order to apply a suitable tensioning force to the drive element. The damping member is connected to the tensioning assembly and is suitable for damping the vibration and oscillation of the tensioning device during operation. The damping member includes a damping material. The stabilizing member is connected to the positioning component and produces a stabilizing torque that is substantially equal and opposite to the gyroscopic torque created by the tensioning members during operation. One preferred embodiment of the stabilizing member is a counterrotating member having a counterrotating contact surface. The rotation of the counterrotating member is driven by contact of the counterrotating contact surface with the contact surface of a tensioning member or with a surface of the drive element. The damping member is suitable for use with a tensioning device having tensioning members with contact surfaces that are fixed in relation to the respective tensioning members. The damping member and the stabilizing member are suitable for use with a tensioning device having tensioning members with contact surfaces that are rotatable about axes which are generally parallel to one another.
