Optimal speed range is 10007000 ftmin 3002130 mmin.

. D Pitch Diameter Large Pulley. Wide Selection of Industrial Controls In Stock at Allied. The arc of contact correction factor corrects the power rating of the V-belt for pulleys where the arc of the contact differs from 180 degrees.

Ht Height of the tooth on the belt. L Belt Pitch Length. Distance between teeth Cb circumference of belt.

Effective friction coefficient μ μsinβ2- Ratio of belt forces T 1 T 2 expμα- Belt tension load T 1 T 1-T 21-T 2 T 1 N. The number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt.

Input power can be split among several driven pulleys by using a power ratio factor for each pulley. Tb Thickness of belt measured from tooth valley to the flat side of the belt. Featuring quick coupling and sanitary fittings valves and accessories hoses and flexible hoses and.

The forces and torques are calculated accordingly. Dpo Outer Diameter of pulley. Hose Assemblies Fittings Adapters.

V W N V P 1 60 09 10 3 2 where. The RPM of the first driven large pulley is transferred to second set small driver pulley and so on. Multiply the correction factors that you found in step 11 with the power rate to find the corrected power rate of the selected standard v-belt.

D Pitch Diameter Small Pulley. Dpi Inner Diameter of pulley. N Number of teeth on pulley.

The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from. V-BELT DRIVES This technical manual contains all important technical information and methods for the design and calculation of drives with Optibelt V-belts and V-grooved pulleys for industrial applications. The larger sheave is mounted on the driven machine.

To determine whether dynamic balancing is advisable perform the following calculation. Drive force T 1-T 2 Pv. Belt speed v π D 1 n 1.

Arc of contact correction factor c 1. D is Diameter in millimeters F is Face Width in millimeters. Db Diameter of belt.

RPM 15500 DF 12. D is Diameter in inches F is Face Width in inches. Dynamic balancing is strongly recommended in applications running at high speeds.

Hutchinson develops and manufactures complete power transmission system incorporating ribbed belts for HVAC Conveying industrial motors agriculture and energy supply markets. RPM 2554 x 15500 DF 12. V-belts trump flat belts with their small center distances and high reduction ratios.

See Table 2 below for typical values. Pd design power as determined in Section 311 W belt weight per foot of length lb. V-belt pulley design calculation A belt is a flexible power transmission element that seats tightly on a set of pulleys or sheaves.

Shaft load F a. Drive torque P2Ï€n 1 Nm. The preferred center distance is larger than the largest pulley diameter but less than three times the sum of both pulleys.

P Pitch of Belt. Belt drive power transmission. These calculations are mainly for existing installations but you could also put it towards your design if you want to calculate what the length needs to be of the belt as long as you already know the distance between the two pulleys and the size of the pulleys.
