The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
In a movable pulley system, the other effort comes from the gravity acting on the load being lifted. This allows the load to be raised with less force applied by the person pulling on the rope.
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
The driver pulley is the pulley connected to the power source (like a motor), while the driven pulley is connected to the driven load (like a conveyor belt). The driver pulley transfers rotational force to the driven pulley through a belt or chain, allowing the load to be moved or operated.
In a pulley system in equilibrium, the forces acting on the pulley must be balanced. This means that the tension in the rope pulling on each side of the pulley is equal, resulting in a state where the pulley is not moving. This equilibrium condition is reached when the net force acting on the pulley is zero.
No it is a lever because you are pushing it forward. If it was a pulley, you would pull it and the object would come down.
The pulley needs to be removed before you can extract the pump, you can get the pulley removal tool at a car parts store.
You may need a pulley (aka gear) puller to pull it off of the crank. The puller comes usually with bolts or claws you can ancor onto the pulley...
That depends on how the pulley is mounted on the motor. If the pulley is welded then no most likely you will have to cut it to get it off. However, if the pulley is fixed to the motor using a bolt/s or other fasteners then yes. Warning: The pulley could be press fit onto the motor. If this is the case it can come off but might not be able to ever go back on.
crankshaft pulley bolt is left hand thread,so it will come out opposite direction to normal bolts
Loosen the tensioner pulley. When the tensioner pulley is loose the belt will come off. Put the new belt on and tighten the tensioner pulley.
Most bolts turn counterclockwise to come off. Year, make, model and which pulley would be helpful.
You can change the serpentine belt on your Chevrolet trailblazer, by loosening the tensioner pulley. With the loosened tensioner pulley the belt will come off easily. Tighten the new belt with the tensioner pulley.
The belt tensioner pulley is held in place by a retaining bolt. The retaining bolt is in the center of the pulley. Remove the retaining bolt and the pulley will come off. Reverse the process to install the new pulley.
Loosen the tensioner pulley on your 1988 Chevrolet Corsica. When the tensioner pulley is loose the serpentine belt will easily come off. Put the new serpentine belt on and tighten the tensioner pulley.
there should be 3 or 4 bolts that hold pulley on, just remove these bolts a pulley should come off. but remove belt first ! if pulley keeps turning while removing bolts. you can hold it stationary with a scredriver or similar.
cause the tensen pulley could be going bad an my need to be replaced or even your alternater pulley can be getting ready to go bad
