The belt runs from the drive pulley to a driven pulley. Economical cost per HP transmitted. This formula also shows the relation between torque and HP.
Special circumstances such as space limitations may lead to a choice of belt cross section different from that indicated in the chart. If you know any 3 values Pulley sizes or RPM and need to calculate the 4th enter the 3 known values and hit Calculate to find the missing value. The Gates Heavy Duty V Belt Drive Design manual shows that a A.
The most work accomplished in the least amount of time equals greater power. Dimensions of V-belts and pulleys together with basic design data are covered in this manual. V-belt is the rubber belt that drives things such as the alternator air conditioning compressor power steering pump and waterpump.
V-belt drive design calculator for shaft load software calculator. Polyband Double-V hex and FHP belts available. Since one horsepower HP 33000 ft-lbsmin required conveyor drive power may be expressed in HP as follows Te in lbs x V in fpm33000 ft-lbsminHP HP After calculating Te it is important to calculate T2 slip slack side tension required to resist slippage of the belt.

The force T required to move the load is the sum of the resultant force R plus the. In order to calculate horsepower it is necessary to determine the resultant force R due to the weight W acting at incline angle a Force R equals Weight W multiplied by sine a. HP d p r k 1004 - 1652 d p - 15747 x 10-4 d p r 2 - 02126 log d p r 1652 r.
The easiest method to calculate a belts HP rating is by using our software Design Flex Pro or. Diameter driven pulley D 2. The driven pulley is 6 inches in radius and is.
Long dependable performance oil resistance and static conducting Full range of Classical A B and C and D-V Wedge 3V 5V and 8V belts. Power in hp HP can be calculated using the following formulas. A handcrank is attached to a drive pulley of 2 inches in radius.
N m - speed driver rpm d m - diameter driver mm in d f - diameter follower mm in Horsepower. This manual does not apply to automotive and agricultural drives. A ratio of 14 to one would be signified by 251.
18022013 V-belt ratings increase as wrap increases. Tension calculator for V-belt. Sprocket Ratio Calculator Hydraulic Cylinder Push-Pull Calculator V-Belt Length Calculator.
Derate non-linearly for smaller diameter. Power Calculations V-Belt. Longer belts have higher HP ratings because they are used with larger pulleys andor larger center distances which decreases bending fatigue in the belt.
V-belt section will transmit about 22 HP per belt for a minimum pulley OD of 3. For example if your small pulley is 80mm diameter and spins at 1000 RPM and you need to find the second pulley size to spin it at. The belt also tends to wedge into the groove as the load increases - the greater the load the greater.
Pulley groove angle β. Basic Horsepower Rating Formulas. 11012008 One with a calculator can reconstruct these figures working from HP transmitted to driving pulley diameter and RPM.
