| Title of Invention | A BELT DRRVE SYSTEM FOR A POWER PLANT |
|---|---|
| Abstract | A belt drive system for a power plant of the type having:a crankshaft pulley (24),an accessory pulley (18/20/22),a motor/generator pulley (14) in mechanical communication with a otor/generator, a belt tensioner (26),a belt tensioner pulley (28), and a power transmission belt (30) trained about said crankshaft pulley, said accessory pulley, said motor/generator pulley, and said belt tensioner pulley, said power transmission belt (30) having spans defined by terminations proximate to each of said pulleys, including intermediate spans beginning at said crankshaft pulley (24) and ending at said motor/generator pulley (14) following the direction of belt travel in normal operation, further including a first span (32) of said intermediate spans having a first termination end proximate said crankshaft pulley (24) and last span (34) of said intermediate spans having a last termination end proximate said motor/generator pulley (14), said tensioner pulley (28) being proximate a termination on end of an intermediate span not being either said first termination end or said last termination end, said belt tensioner (26) being asymmetrically biased by means of bias in a direction tending to cause said power transmission belt (30) to be under tension, said asymmetrical biasing being such that biasing at a level no more than that provided by a spring rate bias, when external forces acting upon said belt tensioner (26) and said tensioner pulley are less than necessary to overcome said spring rate bias, would thereby tend to cause said tensioner pulley to move in an increasing belt tension direction, and that biasing that results from said spring rate bias and a direction reversal resistance, when said external forces acting upon said tensioner and said tensioner pulley are greater than that necessary to overcome said spring rate bias, would thereby tend to cause said tensioner pulley to move in a decreasing belt tension direction, characterised in that said direction reversal resistance is intermittently applied in response to operation mode of said motor/generator. |
