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 for tensioning a belt includes a support housing that defines, at least in part, a spring cavity and an arm pivotably attached to the support housing. A spring is disposed in the spring cavity and is operatively connected to the arm and support housing to bias the arm to pivot relative to the support housing. The spring is a round wire coil spring having an unloaded axial height and wherein the spring cavity has a height greater than the unloaded axial height of the spring.

摘要： A tensioner for tensioning a belt includes a support housing at least in part defining a spring cavity. A damping member having a first friction bearing surface is at least partially disposed in the spring cavity. An arm pivotally attached to the support housing has a second friction bearing surface. A spring is located in the spring cavity and operatively connected to the arm and damping member to pivot the damping member about a pivot location such that the first friction bearing surface of the damping member is biased against the second friction bearing surface of the arm to dampen relative movement between the arm and the support housing.

摘要： A belt tensioner is provided for mounting on a mounting surface of a structure. The tensioner comprises a body, which defines a cavity, and a drain hole that is in communication with the cavity. The drain hole is located on the body so as to be facing the mounting surface of the structure when the tensioner is mounted on the structure. In this manner it is more difficult for contaminants to enter the body than to exit the body.

摘要： A vibration damper for controlling the torsional and bending vibrations in a rotating shaft is provided. The vibration damper includes a hub, an inertia element, and an elastic element that possess a first shear modulus in a first direction and a second shear modulus in a second direction. The hub is adapted to be coupled to the shaft for rotational movement. The inertia element is concentric with the hub and has a mass. The elastic element is adapted to non-rigidly couple the hub and the inertia element. The elastic element may be a non-isotropic composite material having a plurality of fibers dispersed therein.

摘要： A vibration damper and/or isolator for a rotating shaft is provided comprising a hub, an inertia element, a magneto-rheological elastic element interposed between the hub and the inertia element to non-rigidly couple the inertia element to the hub, and an electromagnet operable to produce a magnetic field across the elastic element when energized. The magneto-rheological elastic element, which may comprise a composite of magnetic-responsive particles dispersed within an elastic material, possesses a variable shear modulus that is dependent, at least in part, on the strength of a magnetic field applied to the elastic element.
