摘要： A tensioner for a power transmission system includes two tensioning arms operatively engaged with the strand of the chain or the belt of the power transmission system. The upper end of each tensioning arm is connected to a two way damper which is pivotally mounted between the upper ends of the tensioning arms. When a pre-determined chain tension overload threshold is reached, the amount of torque required to overcome the coefficient of friction the damper allows the tensioner to adjust the tension in the chain with minimal oscillations and minimal phase change variation.

摘要： A tensioner for a power transmission system includes two tensioning arms operatively engaged with a strand of either the chain or the belt of the power transmission system. The upper end of each tensioning arm is connected to a one way rotational clutch which is pivotally mounted between the upper ends of the tensioning arms. The one way clutch rotates in one direction in response to changing chain loads to adjust the tension substantially equally on both strands at the same time. In order to prevent over-tensioning, a damping means is included in the one-way clutch. When a pre-determined overload threshold is reached, the amount of torque required to overcome the coefficient of friction of a spring in the damper allows the one way clutch to slip in the direction opposite from its normal rotational direction, thereby relieving the overload condition on the chain.

摘要： A closed loop chain tensioner system having a drive sprocket, one or more driven sprockets, a first mechanical tensioner located adjacent a slack strand and a second mechanical tensioner located adjacent a tight strand. Each tensioner is independently pivotally mounted to the engine block. The mounting point may be located at any point along the length of each tensioner. The tensioners are then linked to each other by a rigid, solid link. This solid link enables the tensioners to act in unison, thus providing damping across both strands of chain in response to engine torsional variations.

摘要： A belt tensioner apparatus is provided for a pulley assembly having an input pulley rotatably connected to an output pulley via a flexible belt. The tensioner apparatus includes a belt contact device engaged with a first portion of the belt and also engaged with a second portion of the belt different from the first portion of the belt. The belt contact device is coupled to a base so as to enable movement of the belt contact device with respect to the base, such that the belt contact device moves against the second portion of the belt responsive to a tension force created in the first portion of the belt by rotation of the input pulley, to create a tension force in the second portion of the belt.

摘要： A belt tensioner assembly for an internal combustion engine. A pair of tension members such as rollers engages the belt on opposite sides of a driving/driven member, such as a starter/alternator. The tension members are movably secured to the engine block or other device and are spring biased to engage the belt. Engaging the belt at multiple points and on either side of a driving/driven member, a floating tensioning device is created thus facilitating the ability to maintain sufficient minimum tension in the belt to prevent slippage regardless of load conditions.

摘要： A drive belt of an internal combustion engine has a first pulley mounted on a crankshaft of the internal combustion engine, and a second pulley mounted on a shaft of a starter generator of the internal combustion engine. A belt is looped about both pulleys. A tensioner includes two tensioning arms, each of which loading a belt run of the belt and operating either as load-carrying belt run or non-load carrying belt run. Both tensioning arms are disposed to pivot about a rotation axis, with tensioning rollers mounted onto the tensioning arms and spring-biased against the belt. The tensioning arm disposed respectively upon the load-carrying belt run is urged into a stop position by a force applied by the belt.

摘要： A distributor apparatus is disclosed for spreading materials. The apparatus includes a container having a first and a second end and a first and a second side, the ends and the sides defining therebetween an opening for the reception therein of the materials. The container defines an outlet for the distributing therethrough of the materials. A distributing device is disposed in the vicinity of the outlet, the distributing device being pivotally secured to the container about a pivotal axis. The distributing device further includes a frame, a driven device rotatably secured to the frame for ejecting the materials from the container, a driving device for rotating the driven device such that the materials are moved from the container through the outlet by the driven device so that spreading of the materials from the container is permitted, a drive for driving the driving device and a guide for guiding the driving device between the driven device and the drive. The arrangement is such that an approximate sum of a distance travelled by the driving device from the drive to the driven device plus a further distance travelled by the driving device from the guide to the drive remains constant when the distributing device is pivoted between a first location adjacent to the container and a second location of the distributing device away from the container so that slack of the driving device is minimized during pivoting of the distributing device between the locations.
