pulley for what?
Pulley machine type of many! Machine have many pulley, many pulley machine! Type machine, many pulley type. Pulleys, type pulley machine many type. Machine.
The simple pulley was invented in ancient times by an unknown person. The compound pulley was invented by Archimedes.
IMA of a pulley= the number of ropes supporting the load. An easier way is to count how many times the rope wraps around the wheel. :)
Fixed Pulley and Compound Pulley.
To remove a pulley, you typically need to use a pulley puller tool. First, release tension on the belt connected to the pulley. Then, follow the specific instructions for your vehicle or equipment to use the pulley puller to gently remove the pulley without damaging surrounding components.
It would depend on what you want to use the belt and pulley for
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
This all depends on what type of supercharger it is. If you have an Eaton supercharger it is possible that it might be a pressed on pulley. If this is the case then you will need a pulley puller. If the supercharger is a Vortech, Paxton, or ProCharger they all use key ways. So all you need to do is take the bolt off and the pulley might come off. Some times the pulley will not slide off so a pulley puller will work. Or you can heat up the shaft which will cause the pulley to expand and it will then slide right off. DO NOT use a screw driver or any force to pry it off. This can cause damage to the bearings.
To measure pulley size, you would typically need the diameter of the pulley, which is the distance across the center of the pulley through its widest point. This measurement is important for determining the speed ratio between pulleys and calculating mechanical advantage in systems that use pulleys.
