I AM TRYING TO MATCH PULLEY'S TO TURN A GENERATOR SHAFT 3600 RPMS.I AM USING A V-6 3.7AUTO ENGINE.THE ENGINE WILL BE IDLING ABOUT 700 RPMS.THE ENGINE PULLEY IS 7 INCHES IN DIAMETER.I CAN USE ANY LENGTH VBELT.WHAT DIAMETER PULLEY NEEDS TO BE ON GENERATOR SHAFT?

The ratio of pulley diameters is inverse to the ratio of the rotational speeds. The speed ratio is 700/3600, The small pulley will then be (700/3600)*7 = 1.36" It is unlikely that a vbelt that fits a 7" pulley will fit a 1.36" pulley. This may have to be done with an intermediate pulley. Also, the closest you may be able to get in a standard pulley is probably 1.5" in which case the shaft speed will be 3267rpm

There are over 6 billion human beings on our planet. to think of that there is in basic terms one which you will have a functional relationship with is slightly naive. while you're fortunate, you nonetheless discover the guy ideal after the honeymoon era, and something is paintings to maintain that going. A "soul mate" is an incredible theory, yet i do no longer think of that is in any respect lifelike.
