Page 1 This Manual Guides You in Designing Drives Using These Gates V-Belts Super HC ® V-Belts 3V250 through 3V1400 5V500 through 5V3550 8V1000 through 8V5600 Gates Super HC V-Belts combine modern high capacity material with the revolutionary “narrow” cross section pioneered by Gates. They can transmit up to 3 times the horsepower of conventional V-belts in the same drive space—or the same horsepower in 1/2 to 2/3 the space. Super HC belts can be used on all industrial integral horsepower drives. They are also suitable for low and high speed drives in those speed ranges where conventional belts have limited capacity. In many cases, they can replace high maintenance chain and gear drives. Super HC VBelts have exclusive Gates construction features for extra long drive life. Super HC ® Molded Notch V-Belts 3VX250 through 3VX1400 5VX450 through 5VX2000 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. With smaller sheave diameters, these belts offer a higher horsepower rating than any other V-belts on the market. Super HC ® PowerBand® Belts 2/3V800 through 5/3V1400 2/5V500 through 5/5V3500 3/8V1000 through 5/8V6000 2/3VX250 through 5/3VX1400 2/5VX500 through 5/5VX2000 Gates PowerBand Belts were developed by Gates for drives subjected to pulsating shock loads. These include applications such as compressors, rock crushers, hammers or pug mills. A PowerBand belt is made by joining together two or more Gates V-belts with a permanent, high strength tie band. These readily bend over sheaves as easily as multiple V-belts. However, the tie band keeps the belts running in a straight line into the sheave grooves even under violent pulsating or shock loads. And, these PowerBand belts cannot turn over or jump off the drive. Gates PowerBand belts provide the most advanced V-belt drive system available. Page 2 Click Here for Single Page View ® The Gates Rubber Company This Manual Guides You in Designing Drives Using These Gates V-Belts PredatorTM V-Belts Gates Predator V-Belts are specially reinforced for demanding applications such as those typically found in the wood and lumber processing industry, mining, agriculture, oil field equipment and heavy construction. This new generation PowerBand® Belt is made by joining two or more Gates V-belts with a permanent, high-strength tie-band. It bends as easily as multiple V-belts over sheaves, but the tie-band keeps the belts from bending sideways. This lateral rigidity keeps the belt running in a straight line into the grooves even under violent pulsating or shock loads. It cannot turn over—or jump off. These extra heavy-duty V-belts are constructed with a treated fabric cover, aramid tensile and are oil and heat resistant. Available in narrow and classical profiles, they are precision-matched to optimize performance. Hi-Power ® II V-Belts A24 through A180 B28 through B315 C48 through C420 D105 through D660 Hi-Power II V-Belts feature a composite multipurpose construction. Concave sidewalls fill out, making uniform contact with the sheave groove and distributing wear uniformly. The arched top provides superior strength to prevent “dishing” and distortion of the tensile section. The Flex-Weave® cover protects the core of the belt and its extra flexibility allows the belt to bend easily in even the smallest sheaves. Constructed with special rubber compounds, these belts resist oil and heat, ozone, sunlight weather and aging. Its superior length stability assures that Gates Hi-Power II V-Belts require less retensioning and takeup during their service.

Developed and patented by Gates, these Hi-Power II Powerband Belts pull like multiple V-belts, yet have additional lateral rigidity to eliminate problems caused by whipping belts that turn over or come off the drive. These belts operate in standard V-belt sheaves. The tensile section in each belt strand is within the sheave groove and the tie-band does not touch the bottom of the sheave. As a result, Hi-Power II PowerBand Belts operate without slip at low tension (low tension results in lower bearing loads). Tri-Power® Molded Notch V-Belts AX21 through AX173 BX28 through BX300 CX51 through CX360 Especially suited for drives with smaller diameter sheaves, Gates TriPower Molded Notch V-Belts carry a higher horsepower rating than conventional cross-section belts. A special compound provides oil and heat resistance and helps resist ozone, sunlight, weather and aging. A proprietary material surrounding the tensile members bonds the cords and rubber during vulcanization into a unit that provides long service without cord separation. Special notches molded into the belt during manufacturing reduce bending stress. The edges of Tri-Power Molded Notch V-Belts are precisely cut to exact dimensions to assure uniform fit along the sides of sheave grooves.

They run on small diameter sheaves with high horsepower capacities and are precisely manufactured without laps and layers to achieve a uniformity not possible with traditional rubber construction belts. Gates special urethane compound used in Polyflex JB Belts is resistant to fatigue, wear, ozone and environmental conditions. Micro-V ® Belts J Section L Section M Section Gates Micro-V Belts are extremely smooth running and are oil and heat resistant. The truncated rib profile increases flexibility and allows the belt to perform at very high speeds on smaller diameter sheaves. Woven fabric rib surface improves wear resistance and provides a clutching surface. Horsepower ratings exceed RMA standards. Recommended for high-speed applications such as rock crushers, drilling rigs, cranes, road paving equipment and many more.

Page 13 How to Select the Correct V-Belt Drive Using Stock Sheaves and Belts To Design a Drive, Follow These Three Steps: Step 1 Find the Design Horsepower Design Horsepower = (Service Factor) x (Horsepower Requirement) The selection tables for two-sheave speeddown drives, using standard electric motors, start on Page 22. Information includes driveN speed, sheave diameters, speed ratios, belt length, center distance and belt horsepower ratings. A. Select the proper Service Factor from Table No. 2. If your driveN machine is not listed and you cannot find a machine with comparable starting, running and shock load characteristics, turn to Page 266 for assistance in selecting a Service Factor. B. The horsepower requirement of the drive is usually taken as the nameplate rating of the driveR. The actual load requirement of the driveN machine may be used as the horsepower requirement if it is known. This load must be used in those applications where a small auxiliary machine is being driven from a large motor or engine. C. F in d design horsepower by multiplying the horsepower requirement of the drive by the service Factor. Before Selecting a V-Belt Drive, You Need to Know Only These Four Things: 1. The type of application, machine, or work being done. 2. The horsepower rating and speed (RPM) of the driveR. 3. The speed (RPM) of the driveN machine or the required speed ratio. 4. The approximate center distance required. CLUTCHING DRIVES Refer all clutching drive applications to the Product Application Department, The Gates Rubber Company, Denver, Colorado. V-belt drives which use the belt as a clutch require special consideration because the heat generated by belt slip (during engagement and disengagement) on some clutching applications can cause some V-Belt tensile materials to shrink in length. The shrinkage may cause a belt, which is already engaged and driving, to not declutch, or a declutched belt may engage itself and start driving the machine unexpectedly. Depending on the machine and circumstances, either situation could prove dangerous to the machine operator or bystanders. Belts specially designed to minimize or eliminate heat shrinkage may be required.

Page 17 How to Select the Correct V-Belt and PowerBand Belt Drive Using Stock Sheaves and Belts — continued ® Step 3 Step 3 Select the Drive — continued Select the Drive Locate the Proper Drive Selection Table for the Cross Section You Selected. Before following the steps below, refer to paragraph B of Step 3. It provides guidance in the selection process and serves as a final judgment of your selection. B. Final Judgment While selecting or evaluating your drive, consider these facts: 1. If you need to keep sheave face width at a minimum, select the largest diameter drive from the group. 2. Larger diameter sheaves will also keep drive tension, and therefore shaft pulls, at a minimum. A. For Standard Motor Speeds: 1. Read down the driveN speed column which is headed by your motor speed, to an rpm close to the desired driveN machine speed. If you cannot find a driveN speed close enough to meet your requirements, use the Drive Design Section to design with the exact sheave diameters you need. See Page 201. 2. To the right, in the sheave diameter columns, you will find the small and large sheave diameters to order for the drive. These are the two sheaves that will provide the required driveN speeds. Be sure that the motor sheave is equal to or larger than the minimum recommended diameter shown in Table Nos. 3, 4 or 5 on Page 19. 3. Read to the right the center distance value closest to the one specified. The drive components can usually be adjusted to provide for this catalog value. Read up to the top of the column for the correct V-belt for the drive. 4. Immediately below the table, you will find a color key for identifying the horsepower correction factor. Jot down the proper factor for the center distance you have selected. 5. Now continue to the right on the same line to the rated horsepower per belt for your motor rpm. 6. Multiply the rated horsepower per belt by the horsepower correction factor found from the color key to find the horsepower per belt. 3. In addition, larger diameter sheaves will generally give a more economical drive, but you should hesitate to select diameters so large as to require only one belt — you sacrifice multiple-belt dependability. 4. If you have limited space for your drive, consider using the smallest diameter drive from the group. However, sheaves on electric motors must be at least as large as the NEMA minimum from Table Nos. 3, 4 or 5 on Page 19. 5. When your point on the cross section selection chart is near a line, indicating that either of two cross sections can be used, the larger section will generally give a more economical drive. However, in the largest cross sections, this may require the use of standard but nonstock sheaves. In this case the drive using the small cross sections with stock sheaves will usually be more economical. C. Other Drives 1. For drives where driveR speed is other than standard electric motor, see Example on Page 21. For speedup drives, see Example on Page 210. 2. For special drives not explained here (quarter turn, V-flat, idler), see Pages 247 through 254. 7. Divide the design horsepower for the drive by the horsepower per belt to find the number of belts. The answer will usually contain a fraction. Use the next larger whole number of belts. If your drive requires more than the stock number of grooves, there are two possibilities: a. Use the diameters as selected and order the nonstock number of grooves. b. Turn to the drive design section and design a drive using one or two nonstock sheaves. You may be able to design a more economical drive by using larger sheaves (which results in fewer belts) in conjunction with at least one stock sheave. 8. Find the recommended installation and takeup allowances from Table Nos. 38 to 41 on Pages 193 and 194. 9. Calculate the minimum and maximum deflection forces and deflection distance used to statically tension the drive. These values can be found in the Tensioning Section on Pages 212 through 215. Your design is now complete.

Comments Step 1 Results Find the Design Horsepower A. From Table No. 2 on Page 14, Service Factor is 1.2. B. Horsepower requirement of the drive is 10. C. Design Horsepower = 10 hp x 1.2 = 12 hp. Step 2 Belt Section = 3VX Select the Drive A. Turn to the drive selection table for 3VX belts, Table No. 6 on Page 22. 1. Under the column for a motor speed of 1750 rpm, find the driveN speed of 1636, closest one to the desired 1 6 3 5 r p m . T h e r e a r e f o u r s h e a v e d i a m e te r combinations that give this speed. The small sheave d i a m e t e r o f 2 . 2 " i s s m a l l e r t h a n th e N EM A recommended minimum diameter of 3.8", and should not be used. 2. Use the remaining combination of DriveR = 5.6" O.D.; DriveN = 6.0" O.D. The 5.6" DriveR diameter is larger than the NEMA minimum of 3.8". 3. On the same line to the right, the Center Distance nearest to the desired 38" is 38.4". At the top of this column 3VX950 V-belts are specified. This means that using the two sheaves 5.6" O.D. and 6.0" O.D. with V-belt 3VX950, the drive center distance will be 38.4" (See Step 4 below.) 4. The 38.4" center distance lies in the gray area of the table for which the color key at the bottom of Page 23 shows a 1.1 horsepower correction factor. 5. Read to the right, continuing on the same line as the 38.4" center distance, to the column headed 1750 rpm to find the Rated HP per Belt. This value is 7.09. 6. The horsepower correction factor, 1.1 times the rated horsepower per belt, 7.09, is 1.1 x 7.09 = 7.8. This is the horsepower per belt. 7. The design horsepower divided by the horsepower per belt/rib is 12 ÷ 7.8 = 1.5; or 2 belts required for the drive. Step 4 Design Horsepower = 12 Select the Proper V-Belt Section A. From Figure 1 on Page 15, a drive with Design Horsepower of 12 and 1750 rpm of the faster shaft can use a 3VX section Super HC V-Belt. Step 3 Service Factor = 1.2 Pump Speed = 1636 rpm Motor Sheave = 5.6" O.D. Pump Sheave = 6.0" O.D. Center Distance = 38.4" V-Belt Number = 3VX950 Horsepower Correction Factor = 1.1 Rated Horsepower per Belt = 7.09 Horsepower per Belt = 7.8 Number of Belts = 2 Determine Installation and Takeup Allowance A. Center distance allowances for installation and takeup from Table No. 38 on Page 193, are 0.8" for installation and 1.5" for takeup.

Desired fan speed, 1100 rpm. Desired center distance about 43". Comments Step 1 Results Find the Design Horsepower A. From Table No. 2 on Page 14, the Service Factor is 1.3. B. Horsepower requirement is 75. C. Design horsepower = 75 x 1.3 = 97.5 Step 2 Belt Section = 5V or 5VX Select the Drive A. Sheave and Belt Size 1. Calculate the Speed Ratio; 2000 rpm ÷ 1100 rpm = 1.82. 2. Turn to the Drive Selection Tables for 5V/5VX belts. Table No. 7 on Page 44. Read down the Speed Ratio column to find a value of 1.82. 3. The stock sheaves giving this speed ratio are 10.3" and 18.7" O.D. 4. Turn to Formula No. 2 on Page 204 and check sheave rim speed of the driveR. This is approximately 5500 ft./min. which is satisfactory. (Less than 6500 ft./min.) 5. Reading across the same row containing the 10.3" and 18.7" sheaves, find a center distance of 43.0", with belt 5VX1320. B. Determine Number of Belts Required 1. Find rated horsepower per belt = (Basic + Add-on) x Correction Factor. (a) Turn to Table No. 10 on Page 71 and find Basic Horsepower of 37.2 for sheave size of 10.3" and speed of 2000 rpm. On the same line across, find add-on horsepower of 1.4 for speed ratio of 1.82. Total is 37.2 + 1.4 = 38.6. (b) Determine Correction Factor. At the bottom of Page 44 where belts and sheaves were selected, note correction factor of 1.0 for C.D. of 43". Therefore the 38.6 horsepower from (a) above is unchanged. c) Rated horsepower per belt = 38.6. 2. Divide the Design Horsepower by the Rated Horsepower per Belt/Rib: 97.5 ÷ 38.6 = 2.5 or 3 belts. Step 4 Design Horsepower = 97.5 Select the Proper V-Belt Section A. From Figure No. 1 on Page 15, a drive with a Design Horsepower of 97.5 and 2000 rpm of the faster shaft requires a 5V or 5VX Section belt, Super HC Type. The belt section finally selected will depend on length required. Step 3 Service Factor = 1.3 Speed Ratio = 1.82 Engine Sheave = 10.3" Fan Sheave = 18.7" Sheave Rim Speed = 5500 ft./min.

However, its extremely important to evaluate the structural integrity of the sheave. The forces due to the actual power being transmitted as well as centrifugal forces (especially on drives over 6,500 feet per minute), should be checked before selecting a material.

However, its extremely important to evaluate the structural integrity of the sheave. The forces due to the actual power being transmitted as well as centrifugal forces (especially on drives over 6,500 feet per minute), should be checked before selecting a material. Nonferrous and nonmetallic materials should be avoided due to poor wear resistance. Nonmetallic material also lacks thermal properties for good heat dissipation.

Under favorable storage conditions, good quality belts retain their initial serviceability and dimensions. Conversely, unfavorable conditions can adversely affect performance and cause dimensional change. Good storage facilities and practices will allow the user to achieve the most value from belt products. Power transmission belts should be stored in a cool and dry environment with no direct sunlight. When stacked on shelves, the stacks should be small enough to avoid excess weight on the bottom belts which may cause distortion. When stored in containers, the container size and contents should be sufficiently limited to avoid distortion, particularly to those belts at the bottom of the container. Some things to avoid: Do not store belts on floors unless a suitable container is provided. They may be susceptible to water leaks or moisture or otherwise damaged due to traffic. Do not store belts near windows which may permit exposure to sunlight or moisture. Do not store belts near radiators or heaters or in the air flow from heating devices. Do not store belts in the vicinity of transformers, electric motors or other electrical devices that may generate ozone. Also avoid areas where evaporating solvents or other chemicals are present in the atmosphere. Do not store belts in a configuration that would result in bend diameters less than the minimum recommended sheave or pulley diameter for normal bends. Equipment using belts is sometimes stored for prolonged periods (six months or more) before it is put in service or during other periods when it is idle. It is recommended that the tension on the belts be relaxed during such periods and that equipment storage conditions should be consistent with the guidelines for belt storage. If this is not possible, the belts should be removed and stored separately. Handling of Polyflex JB belts is also important. Due to the high performance characteristics of Polyflex JB belts, do not crimp or tightly bend the belt. Belts should not be bent inside tighter than the smallest recommended sheave diameter for that particular cross section (See Chart A on left). Backside bending should be limited to the values specified in Chart B on left. Minimum Diameter Belt Cross Section (In.) (mm) 5M 7M 11M 2.9 4.9 6.4 74 125 163 The belt may be cleaned by wiping with a rag slightly dampened with a light nonvolatile solvent. Soaking or brushing on such solvent is not advisable. The belt must be completely dry before using on the drive. More obviously, sanding or scraping the belt with a sharp object to remove grease or debris is not recommended.
