The tensioning pulley arrangement for a belt drive in an engine, is provided. In one example, the tensioning pulley arrangement includes a first tensioning pulley and a second tensioning pulley tensioning a belt with a spring force and a spring preload force generated by a first spring device coupled to the first and second tensioning pulleys. The tensioning pulley arrangement further includes an intensifying device that decreases belt tension during low belt load conditions and increases belt tension during high belt load conditions. In this way, friction losses during low belt loads may be reduced and belt slippage caused by high belt loads and/or dynamic shifts in belt loads may also be reduced.

There is provided a belt tension adjusting device for an engine having a chain cover; a mount attaching portion; and a driving belt. An arm is swingably supported about a hinge pin fixed to the engine. A tensioner pulley is supported by the arm to be in contact with the driving belt. An auto tensioner is connected to the arm and configured to press the arm. The auto tensioner is arranged in a space, which is overlapped with the chain cover as viewed from a front side of the engine and located between the mount attaching portion and a crank pulley.

Based on further ingenuity, it is possible to support a heavy and large electric motor on an engine body with sufficient strength while driving the electric motor with a belt without slipping, thereby providing a more streamlined industrial hybrid engine. The industrial hybrid engine is provided with an endless rotation band wound around a drive pulley of a crankshaft and a motor pulley of an electric motor for motive power. The electric motor is attached to an engine case in a position-fixed state using one support bracket. The support bracket includes first and second support portions for attaching the electric motor, and attachment portions positioned between the first and second support portions for attaching the electric motor to the engine case.

A method and apparatus that circumvents belt path obstacles in a Corvette C8 engine for transferring auxiliary power from the engine crankshaft output pulley to a supercharger input pulley by using a drive path transfer apparatus including a transfer input pulley located in the same plane as the crankshaft pulley and connected to it with the main drive belt, a transfer output pulley in a second plane spaced inboard of the first plane including the supercharger pulley, a secondary belt joining the transfer output pulley and the supercharger pulley, and a coupling shaft having the transfer input pulley at one end and the transfer output pulley at the other end, the coupling shaft being rotationally mounted in a two-piece installable bracket secured on the engine block in a location to the side of the obstruction, thereby transferring power from the engine to the supercharger without interference from the obstruction.

An implement coupler for a work vehicle includes a support frame having a drive opening and an array of electric machine mounts arranged about the drive opening. A gearbox is mounted on the support frame and has a gearbox shaft extending through the drive opening. At least one drive pulley is coupled to the gearbox for rotation. At least one endless member is disposed about the drive pulley for rotation therewith. A first electric machine is mounted on the support frame at a first of the electric machine mounts and having a first input pulley coupled to the drive pulley by the at least one endless member.

A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element configured to receive a screw, a rotating outer element that is mounted to rotate coaxially about the fixed inner element and is intended to cooperate with the transmission element, and an annular protective flange bearing against a lateral surface of the fixed inner element. The fixed inner element provides a sleeve axially protruding from the lateral surface. The flange provides an inner axial portion mounted securely on an outer surface of the sleeve.

A tensioner includes a base, a tension arrangement rotatable at the base, a damping member being rotated in a loading direction by the tension arrangement, and an elastic member biasing against the damping member. The position of the damping member depends by the layout geometry of the specific application and is directly in opposition to the hub load. The reaction force of the cylindrical surface of the base on the damping member is very near to the plan of the external forces represented by the hub load to minimize the deflection of the shaft. The tension arrangement is rotated to push the damping member for generating a first positive tension between the damping member and the base, and to expand the elastic member radially for generating a second positive tension between the elastic member and the damping member, so as to enhance a damping force of the tensioner.

A pulley device comprising a pulley and a bearing. The pulley has at least one “C-shaped” pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. The outer cylindrical surface of outer ring is provided with at least one recess having in cross-section, a concave internal profile. The pulley part is provided with at least one protruding portion which inwardly extends beyond the inner cylindrical surface of inner portion. The protruding portion is received in a corresponding recess of outer ring so as to block the pulley part with respect to the outer ring in both axial directions.
