Something about carry idler
To operate most efficiently and with minimum belt wear the tension of the belt must be periodically adjusted to an optimum tension range sufficiently high to efficiently transmit power without excessively stretching and wearing the belt. To accomplish this belt tensioning it has become common to utilize carry idler mechanisms comprising an idler pulley positioned between the driving and driven pulleys to engage and apply tension to the drive belt. The more sophisticated idler mechanisms employ a tensioning idler pulley which is resiliently biased into tensioning engagement with the drive belt. By resiliently biasing the idler pulley many shortcomings associated with rigidly mounted idler mechanisms are overcome and the mechanism is better able to compensate for many operational variations which affect belt tension, such as variations in load and belt wear.
