Formula to calculate v-belt length?
The answer is: L = pi x (D + d)/2 + 2 x ( C x Cos(a) + a x (D-d)/2) where a = arcsin(D-d)/(2 x C) in radians. Where C is the center distance, D is the large pulley diameter, and d is the small pulley diameter.

A belt runs a pulley of radius 6 cm at 80 rpm a what is the angular velocity of the pulley in radians per second b what is the linear velocity of the blt in centimeters per second?
-- 80 rpm = 160 pi per minute = (160 pi / 60) = (8/3 pi) radians per second.-- Circumference = 2 pi R = 12 pi centimeters.Linear velocity = (circumference x RPM) or (radius x angular velocity).Let's use the second one, since we already calculated the angular velocity, and it's in seconds.Linear velocity = (radius) x (angular velocity) = (6 x 8/3 pi) = 16 pi = 50.27 cm/sec (rounded)
If A gear of radius 0.4 m and a gear of radius 1.2 m are connected by a belt as in the following figure if the smaller gear is rotating with an angular velocity of 10rad find the angular velocity?
# We usually use belts to connect PULLEYS; Chains to connect SPROCKETS. Gears have teeth and usually directly mesh together without belts. However, there are gear-like pulleys that have teeth on them but require belts that also have teeth. Possibly what your thinking of... but the math problem is the same with or without a belt. # The key is to recognize the ratio between the pulleys (or sprockets or gears.) 1.2m / 0.4m = 3 ... so the ratio is 3:1 # If the smaller pulley (gear) is the drive, then the driven (bigger) one will turn 1/3 times for each turn of the small one, for a ratio of 3:1. If the big pulley (gear) is the drive, then the driven (smaller) one would turn 3 times for each single turn of the big one. # You did not state the time of rotation. (per second? per minute?) Regardless, the the big pulley (gear) will have 1/3 (one third) the angular velocity of the small pulley (gear.) So (ANSWER) your BIG pulley (or gear) will have angular velocity of 3.333333... (three and one third) radians per time unit.
What is the velocity ration of a pulley?
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.
What is velocity ratio of a pulley?
The ratio for a simple pulley (not a pulley block), using an inelastic string, is 1.
What is velocity ratio of single fixed pulley?
The velocity ratio of a single fixed pulley is 1. This means that the input and output speeds are equal. The pulley simply changes the direction of the force applied.
How do you calculate velocity ratio in a pulley?
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.
What pulley drives alternator belt What is wrong if this pulley isn't turning?
the pulley on the harmonic balance drives the alternator belt. this is the pulley at the bottom of the engine ,on the front of the crank shaft if this pulley is not turning you have a problem. this means either the key is missing or the crankshaft is broken
Why crowning in pulley is necessary?
to avoid the slip , increase the velocity ratio and increase belt and pulley life... thanku..:)
What simple machine is turning on a sprinkler?
a gear or a pully
Squeal from a pully from under the hood when motor is running on a C5 corvette?
if there isn't anything wrong with the belt the pulley is turning, check to see if the pulley is stuck, you might need to replace the pulley ( about $30 )
How do you remove the crankcase pulley without it turning?
Use a pneumatic or electric impact wrench.
A ball of mass m is tied to a string that is wrapped around the outside of a pulley. The pulley which is a uniform solid disk also has a mass m and the pulley rotates without friction about the axle t?
The tension in the string will be equal to the centripetal force required to keep the ball in circular motion. This tension will then cause the pulley to rotate. The angular acceleration of the pulley can be determined by utilizing torque equations with the moment of inertia of the pulley and the tension in the string.
