V-Belt Drive Selection Handbook THE BALDOR•MASKA® SELECTION HANDBOOK www.baldor.com - www.maskapulleys.com Introduction This reference guide for selecting V-Belt drive components is for those that prefer, or need to do, a manual selection. Engineers, designers, mechanics, distributors - all will be able to rapidly find a drive for their application. For specific designing, please refer to our on-line selection program (see below). Is it a new engineering drive? Or does a piece of equipment need to be redesigned? Or a distributor simply needs to verify replacement parts? The Baldor•Maska® Reference Booklet provides all the necessary information to define the required parts. NOTE: An original aspect of this guide pertains to the power rating calculation. The basic power rating is evaluated according to the size of the sheave & the speed of the drive. A length correction factor and an arc correction factor have to be applied to adjust this basic power rating depending on the ratio and the center distance. In the Drive Selection Tables, the adjusted power rating is presented including both correction factors, compared to existing tables that only show basic horsepower values. You will find the following herein: • Selection Tips • Most commonly used engineering formulas in the PT Industry (Ratio, Rim speed, Power, Torque and Dynamic Balancing) • Drive selection tables for Classical (A, B, C, D) and Narrow (3V, 5V, 8V) V-belts • Other useful information on Baldor•Maska® V-belt sheaves (pertaining to QD bushings, face width, standard number of grooves) Choosing the correct Baldor•Maska® sheaves and belts for your drive application will be more accurate and easier! For on-line use, please try our "Drive Selection Program". Build your own Drive Selection directly on our web site or download the program onto your computer. www.maskapulleys.com Recommended Drive Selections are designed for use with Baldor•Maska® components (sheaves, bushings and V-belts) which meet or exceed MPTA & RMA standards. The use of lesser quality products can affect the life expectancy of the drive. Selections are as accurate as possible; Baldor is not responsible for ANY design errors.

To evaluate a selection quickly, simply go through these steps. 1 2 3 4 5 6 7 8 9 Determine your drive requirements. How much power do you need to transmit and at what speed? Based on Table 1 (pg. 6), choose the Service Factor for your particular application. Determine the design horsepower using the Design Horsepower formula (see below). Based on your results, determine which belt section would be appropriate for your drive according to Figure 1 or Figure 2 (pg. 7). Narrow belt sheaves are more compact than Classical belt sheaves. Some belts are more appropriate for specific applications. Determine the ratio of your drive application based on the Ratio formula (see pg. 5) and find the closest value in the Drive Selection Tables for your selected belt section (see Index). A centre distance has been pre-selected based on the drive size (see pg. 18). Find the number of belts required by dividing the design horsepower by the belt/HP listed in the table. Verify the validity of this drive by consulting the number of grooves available in these sheave sizes in Table 8 (pg. 13). Verify if dynamic balancing is needed for each sheave based on the Dynamic or Two-Plane Balancing formula (pg. 5). Note that Standard Face Width dimensions can be found in Table 9 (pg. 13). Consult our “Useful Information” section for complementary helpful details concerning V-belt drive applications.

Engineering formulas Design Horsepower Adding a Service Factor to the required power to be transmitted, called nominal horsepower, ensures the efficiency of a drive. This nominal horsepower refers to the motor horsepower or required horsepower for the application. A Service Factor takes into account such situations as power losses due to vibration, shocks, heat and other related factors caused by the motor and the application. The Design Power is calculated based on these considerations thus producing more accurate results to ensure that the drive will function more efficiently. HP’ = SF x HP SF is service factor HP is basic horsepower HP’ is design horsepower 4 Engineering formulas A ratio is a proportional factor between two similar objects of different sizes. In a belt drive system, a ratio is used to determine the speed relation between two v-belt pulleys. The speed ratio would be stable if slippage did not occur; however as belt slip is inevitable, the ratio varies and is therefore only theoretical. If the speed ratio is < 1 (ex. 1:4), we refer to a speed up system; if the ratio is > 1 (ex. 4:1 ), it’s a speed reduction system. In both cases, the ratio is obtained using the dimensions of the input drive (driver) pulley and the output (driven) pulley. In the following ratio, RS is the speed ratio, D1 the diameter of the driver pulley, D2 the diameter of the driven pulley: D2 D1 Speed & Velocity With reference to a belt drive system, the formula to find rim speed, or belt speed, is: Rim Speed [ft/min] = Pulley Diameter [in] x π x RPM x 1/12 [ft/in] OR FPM = Pulley Diameter [in] x 0.2618 x RPM Power In mechanical engineering, power is a measure of performance or capacity and is defined as the amount of work performed in a given time. The most work accomplished in the least amount of time, equals greater power. This formula also shows the relation between torque and HP. Power in hp (HP) can be calculated using the following formulas: OR HP can be converted to kilowatts as follows: HP = Kilowatts X 1.341 Dynamic or Two-Plane Balancing Dynamic balancing is strongly recommended in applications running at high speeds. To determine whether dynamic balancing is advisable, perform the following calculation. D is Diameter in inches F is Face Width in inches D is Diameter in millimeters F is Face Width in millimeters The resultant RPM is the maximum recommended operating RPM for a sheave or pulley with a single plane balance (static balancing). Note: If the sheave or pulley is to be operated at a higher speed, a two plane balance is recommended. 5 DESIGN FACTORS According to RMA Standards The selection of a V-belt drive for any application should be based on the nature of the load and the type of driving unit. Service Factors for different kinds of driven machines combined with different types of driving units are shown in Table 1 below. The driven machines are representative examples only. Select a driven machine whose load characteristics most closely ressemble those of the machine being considered. Multiply the rated motor power or power demand of the driven unit by the selected service factor to obtain the “design power”.

Occasional inspection however, will ensure optimal drive efficiency, and one sign of wear to look for, that is often overlooked, is the rounding or deepening of V-belt pulley (hereafter referred to as sheaves) grooves. Signs to look for: One sign of worn grooves is that it cause one or more belts to ride lower than the others, known as “differential driving”, resulting in premature wearing of belts and reduced performance levels (Image 1). Are one or more of the belts slack, while others are tight in a proper tensioned drive? This is a sign some may be riding higher than others due to rounded grooves. Or, is the bottom of the groove shiny? Then this indicates that the sheave, the belt or both are very worn and the belt is “bottoming”. Belts, depending on the type, can ride at or above the highest point of the sheave, but they should never be allowed to touch the bottom of the groove. If they do, the sheave should be replaced immediately. How to be sure? A handy, inexpensive tool to have on hand is a Sheave Gage (Part #006346). For use with all classical, narrow and A/B combination sheaves, choose the proper key based on the belt section and the size of the sheave. Insert it into the groove (Image 2) until the rim touches the flange, and if there is more than 1/32" of wear, the time has come to replace the part. If the wearing is premature, it could be caused by misalignment between the sheaves, thus forcing the belts in and out at an angle to the groove. The cost of replacing the sheave is soon offset by the number of belts that will be quickly ruined if the sheave sidewalls are rounded, if they “touch bottom” and slip or burn, or through decreased performance levels as a result of reduced wedging action and less gripping power. 16 DRIVE SELECTION TABLES 17 DRIVE SELECTION TABLES POWER RATING NOTICE In the following tables, the power rating calculation is based on RMA/MPTA standards. Here are some considerations when consulting the tables. Adjusted power rating The basic power rating is evaluated according to the size of the sheaves and the speed of the drive. A length correction factor and an arc correction factor have to be applied to adjust this basic power rating depending on the ratio and the center distance. In the following tables, the adjusted power rating is presented, including both correction factors, compared to other existing tables that only show basic horsepower values. When different center distances than those suggested (*) To simplify these tables, a typical center distance has been evaluated for each sheave combination. For other center distances than those suggested in the tables, here are certain factors that should be taken into consideration: Longer center distances mean slightly higher power ratings and inversely, shorter center distances mean lower power ratings. For high ratio drives, small center distance changes may affect the power rating considerably. Minimum recommended diameter According to the RMA, there are minimum recommended sheave diameters depending on the belt used. Drives not adhering to this standard have been calculated but are shown with a shaded area for practical purposes. Maximum sheave rim speed Standard Maska sheaves are designed to operate up to 6,500 FPM as per industry standards. Drives exceeding this speed require a ductile iron construction and are shown with a “-” sign in the table.
