01042008 Later demands for more powerful machinery and the growth of large markets such as the automobile industry spurred new belt designs.
V belt design. The Design Power is calculated based on these considerations thus producing more accurate results to ensure that the drive will function more efficiently. Our Application Technology experts offer you free support service regarding the application of our products and also help. The belt also tends to wedge into the groove as the load increasesthe greater the load the greater the wedging actionimproving torque transmission and making the V-belt an effective solution needing less width and tension than flat belts.
Tight side tension pounds HP. The selection of type of V-belt cross-section depends upon two factors namely the design power and the speed of faster pulley. Dimensions of V-belts and pulleys together with basic design data are covered in this manual.
Arc of Contact correction. The v-belts are made of rubber with fabric cords to transmit power and its covered with a protective layer. Dont Forget Sheaves Sheaves are essential V-belt drive com-ponents.
A v-belt is a unique mechanical linkage with a cross-section that resembles an isosceles trapezoid. In a notched V-belt are designed to increase belt flexibility and reduce bending stresses especially on small sheaves. Factors caused by the motor and the application.
The pulleys establish the degree of flexing and the belt speed and In this manual the. A constant for V-belt design 05123 q. If in drive design the centre distance C is not specified then it should be set at around 2D 1 R1 but preferably not less than D 2.
Belt speed feet per minute Slack Side Tension T2 33000 125 - FA x HP FA x V T2. Rotational speed driver pulley n 1. As noted earlier how well a V-belt fits into the sheave determines how much power the belt drive can transmit and how efficiently it oper-ates.
Diameter driver pulley D 1. This manual covers the four classical V-belt cross sections and pulley groove sizes designated A B C D. According to the unique cross-section shape of v-belt the function of the neural layer and strong layer in different place of strong layer can be obtained.
Pitch Length Inside length correction L Li δ For example E 3333 is having C-section belt and 3333 mm inside length. Pulley groove angle β. In a belt drive system a ratio is used to determine the speed relation between two v-belt pulleys.
Select the standard pulleys. V-belt drive design calculator for shaft load software calculator. Design Pulley Speed Ratio.
Button wont be active without checking. If you already have registered User ID and need to download this program againplease input your User ID and password below and click Download. 18102016 V-belts are designed by the symbol of cross section with the inside length of the belt in mm.
20160331 V-belt design program was added. Arc of Contact Tight Side Tension T1 41250 x HP FA x V T1. V-belts with a.
Horsepower HP FA. Slack side tension pounds FA. Gates Super HC Molded Notch V-Belts are designed for use where conventional V-belts drives are impractical where space weight or sheave limitations are present and where increased horsepower capacity of production is required and higher speed are necessary.
Diameter driven pulley D 2. Shape of the belt tracks in a mating groove in the pulley or sheave with the result that the belt cannot slip off. The v-belt and its complementing pulley create the most efficient belt drive known sometimes achieving 98 transmission efficiency.
Arc of Contact correction factor V. The tension in the belts and the diameters of drive be correctly designed. To create new account please read below disclaimer and checking the I agree to the disclaimer.
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. Calculate the required speed ratio and select the pair of pulleys from the standard list so as to give the speed ratio as closer to the. Nominal dimensions of the four cross sections are given in Table 1.
Based on the characteristic of v-belt we can get a new two-layer v-belt and make the. With smaller sheave diameters these belts offer a higher horsepower. The cords transmit the force from the driver to.
The Structure Design of a New V-Belt. Center to center distance. 01122017 Select the type of V-belt cross-section.
V-belt drives are essentially short centre drives. Since the diameters and belt length are discrete variables so also is the theoretical centre distance though in the absence of idlers the nominally fixed.
