PowerGrip® GT®3, HTD® and Timing Belt Drive Selection Procedure – single sided Step 1. Determine design load Service factors between 1.5 and 20 are generally recommended when designing small pitch synchronous drives. Knowledge of drive loading characteristics should influence the actual value selected. A higher service factor should be selected for applications with high peak loads, high operating speeds, unusually severe operating conditions, etc. Lower service factors can be used when the loading is smooth, well defined, etc. and the reliability is less critical. Some designs may require service factors outside the 1.5 to 20 range, depending upon the nature of the application. Contact Gates Product Application Engineering for additional information. Stall torque of the driveR, or peak torque of the driveN unit, may be part of the nameplate data. If not, calculate Torque (Q) by using these formulas: D. Check the Belt Speed, V, of the smaller sprocket selected, using the

following formula: V (fpm) = 0.262 x Sprocket PD (in) x Sprocket RPM V (m/s) = 0.0000524 x Sprocket PD (mm) x Sprocket RPM and, m/s = 0.00508 x fpm NOTE: Belt speeds in excess of 6,500 fpm (33.02 m/s) require special sprocket materials and dynamic balancing. Step 3. Determine belt length and nominal center distance. A. Using the allowable range of center distances required by the drive design, calculate the belt Pitch Length (PL) using the following formula: PL = 2CD + [1.57 x (PD + pd)] + Q (lb - in) = 63,025 x Shaft HP , Shaft RPM Where CD = Drive center distance (in) PD = Large pitch diameter (in) pd = Small pitch diameter (in) Q (lb - in) = 8.85 x Q (N - m) or Q (oz - in) = 16 x Q (lb - in) Peak Design Load = Load x Service Factor NOTE: When performing drive calculations based upon torque loads, drive input/output power is constant but drive input/output torque is not. Drive input/output torque is a function of the speed ratio. Drive designs should be based upon the smaller,

faster sprocket, at the torque load calculated for its operating speed. These critical drive parameters should be used for all engineering calculations. See engineering calculations on Page 103 for additional formulas and unit conversions. Step 2. Determine belt pitch and select sprockets. A. Select Belt Pitch by using the Belt Pitch Selection Guide on pages 25, 41 and 53. B. Determine the speed ratio by dividing the larger speed, Sprocket Pitch Diameter or Sprocket Groove Number by the lesser speed, Sprocket Pitch Diameter or Sprocket Groove Number. C. Refer to the appropriate Sprocket Diameter Tables on pages 29-31, pages 46-49 or page 57-58. Select sprockets based upon speed ratio and drive requirements. Use stock sprocket sizes whenever possible. 12 (PD - pd)2 4CD Using the calculated range of pitch lengths, select a belt of the proper length from the appropriate belt length table. Use a standard length as shown in the tables on pages 15-16, pages 39-40 or pages 51-52, if

possible. B. The approximate nominal center distance for the drive can be calculated using the following formula: Center distance = K + K 2 - 32 (PD - pd)2 16 Where K = 4PL - 6.28 (PD + pd) PD = Large pitch diameter (in) pd = Small pitch diameter (in) PL = Belt pitch length (in) Tables of the proper belt pitch nearest to, but greater than, the peak design load from Step 1. Torque or horsepower ratings for various belt widths can be calculated by multiplying the table rating by the appropriate belt width multiplier. When designing with PowerGrip® GT® 3 or HTD, use the belt length from Step 3 to find the proper belt length factor in the Length Factor Tables included with each Belt Width Selection table. Multiply the torque rating selected above by the belt length factor to obtain the corrected rating. For all designs, the torque or horsepower rating must be equal to, or greater than, the peak design load of Step 1. NOTE: The torque or horsepower ratings are based on 6 or more teeth in

mesh for the smaller sprocket. Calculate the teeth in mesh for the selected drive design using the Teeth In Mesh Formula on Page 104. If the teeth in mesh is less than 6, the drive must be de-rated as indicated, which may require redesign for additional drive capacity. Step 5. Determine proper belt installation tension. Procedures to calculate proper belt installation tension for specific applications are included on pages 65-66. Step 6. Check and specify drive components After the drive system components have been selected and checked against drive system requirements, contact Gates Product Application Engineering before going into production.

Determine belt width Belt Width Selection Tables on pages 18-21, pages 42-43 and page 54 show the load ratings for the stock widths of each of the stock belt

pitches. Using the smaller sprocket groove number and rpm as determined in Step 2, locate a torque or horsepower rating in the Belt Width Selection ® Polígono Indutrial O Rebullón s/n. 36416 - Mos - España - rodavigo@rodavigocom PowerGrip® GT®3 Belt Drives Belt Construction 3. Neoprene Teeth PowerGrip® GT® 3 drives provide positive, troublefree power transmission in low-speed high-torque applications and offer many advantages over conventional chain, gear and other belt drives. Advantages: • Higher capacity 4. Nylon Facing • Improved registration • Reduced noise • No lubrication required 1. Tensile Member • Minimal elongation due to wear • Corrosion resistance 2. Neoprene Backing • Excellent abrasion resistance • Clean operation • Long trouble-free service Construction Features The tooth design substantially improves stress distribution and allows heavy loading. The molded teeth enter and leave the sprocket grooves smoothly with negligible

friction – functioning in much the same way as teeth on a gear. Construction consists of these components: 1. Tensile Member – Provides high strength, excellent flex life and high resistance to elongation. 2. Neoprene Backing – Strong Neoprene bonded to the tensile member for protection against grime, oil and moisture. It also protects from frictional wear if idlers are used on the back of the belt. 1. 2. 3. Neoprene Teeth – Shear-resistant Neoprene compound is molded integrally with the Neoprene backing. They are precisely formed and accurately spaced to assure smooth meshing with the sprocket grooves. 4. Nylon Facing – Tough nylon fabric with a low coefficient of friction covers the wearing surfaces of the belt. It protects the tooth surfaces and provides a durable wearing surface for long service. 3. 4. ® Polígono Indutrial O Rebullón s/n. 36416 - Mos - España - rodavigo@rodavigocom 13 PowerGrip® GT®3 Belt Drives Single Sided Belt Drive Systems Gates 2mm,

3mm and 5mm pitch PowerGrip® GT® 3 belts have helically-wound fiberglass tension members embedded in a Neoprene body with the belt teeth faced with a tough wear-resistant nylon fabric. As shown below, three principal dimensions of a belt (Pitch, Pitch Length and Width) in millimeters are used to specify a PowerGrip® GT® 3 belt: 300 3MGT 09 Pitch Length Pitch Width Belt pitch is the distance in millimeters between two adjacent tooth centers as measured on the pitch line of the belt. Belt pitch length is the total length (circumference) in millimeters as measured along the pitch line. The theoretical pitch line of a PowerGrip® GT®3 belt lies within the tensile member. Three principal dimensions of a sprocket – number of grooves, pitch and belt width in millimeters – are used to specify a PowerGrip® GT® 3 sprocket as shown below: 3MR 22S 09 Pitch Number of Grooves Belt Width PowerGrip® GT® 3 drives have a higher load capacity than PowerGrip® HTD® and

PowerGrip® Timing drives. They also feature equivalent or better backlash characteristics when compared to PowerGrip® Timing drives. These attributes make PowerGrip® GT® 3 the drive of choice for today’s design engineers. Add 0.080” (203mm) to sprocket OD for approx diameter over belt dimension. Add 0.168” (427mm) to sprocket OD for approx diameter over belt dimension. PowerGrip® GT® 3 belts must run in PowerGrip® GT®2 sprockets. PowerGrip® GT® 3 belts are not compatible with PowerGrip® HTD® sprockets, or any other sprockets available on the market. Add 0.120” (305mm) to sprocket OD for approx diameter over belt dimension. 14 ® www.gatescom/drivedesign Polígono Indutrial O Rebullón s/n. 36416 - Mos - España - rodavigo@rodavigocom PowerGrip® GT®3 Belt Drives PowerGrip® GT®3 Belt Lengths and Widths 2mm Pitch Belt Lengths Description 2MR-74 2MR-76 •2MR-100 •2MR-112 •2MR-124 •2MR-126 •2MR-130 •2MR-132 •2MR-134 •2MR-136 •2MR-140
