  • Automatic tension adjuster for fan belt
    Patent number: 5290207
    Abstract: An automatic tension adjuster for a fan belt which automatically adjusts the tension of a fan belt even at the time of sudden decrease in speed of an associated engine so as to prevent slip, so-called "creak" or the like from occurring between the fan belt and a crank pulley. For this purpose, there is provided an adjusting means (30) for automatically adjusting an amount by which a lever (5) swings in a direction opposite to that in which it has pushed a tension pulley (4) against the fan belt (8) when the rotational speed of the crank pulley (1) suddenly lowers. This adjusting means includes the lever (5), a yoke (10), an adjusting bolt (13), a lock nut (14) and a fixing bracket (20).
