How to Choose Automotive Pulleys

2014/12/12This ratio can be found by dividing the diameter of the smaller pulley into the larger one. For example, a 6-inch water pump being driven by a 7-inch crank pulley would yield a 1.16:1 pulley ratio. In this scenario, the water pump pulley spins 1,160 times for every 1,000 turns of the crankshaft pulley. Get price

Pulley Ratio Chart

The pulley ratio is the diameter of the crankshaft pulley divided by the diameter of the alternator pulley. Multiply that number times the engine RPM to get the alternator RPM. For example, a 6 inch crankshaft pulley and a 2 inch alternator pulley equals a pulley ratio of 3:1. Get price

How to calculate motor drive torque for belt and pulley

J p2 = inertia of idler pulley (provide by manufacturer, or calculate) (kgm 2) J l = inertia of load (kgm 2 ) Although we assumed above that the drive and idler pulleys have the same radius, their inertias may be slightly different, since the drive pulley is toothed and, therefore, has a slightly larger radius and higher mass than the idler pulley.

How to Calculate the Speed of Two Different Pulleys

2018/4/24Calculate the pulley ratio by dividing the pulley's pitch diameter by the pitch diameter of the drive pulley. For example, suppose the drive-shaft has a diameter of 2.2 inches, and two pulleys driven by the belt have diameters of 4.4 inches and 2.8 inches. The first Get price

Evaluating Pulley Weights for Home Gyms

2013/12/17Pulley Weights: The Basics The main number to concentrate on is the ratio. The ratio tells you how the weight is handled when you pull the cable along the pulley system. For example, if you have a standard 200-lb. stack, a 4:1 ratio reduces the actual weight Get price

Pulleys and Lifting

Velocity Ratio (sometimes called movement ratio)- is defined as the ratio of the distance moved by the effort to the distance moved by the load. Using the example above. If the load is lifted 2 metres, above the pulley wheel - the rope on the right hand side must be shortened by one metre and this also applies to the left hand side. Get price
