This range, which complies with the international standards, covers a large variety of applications. CHARACTERISTICS AND ADVANTAGES OF TEXROPE® STB BELTS This handbook specifically covers TEXROPE®’s synchronous belt line, which has long enjoyed an excellent reputation for its outstanding quality/price ratio – both in standard and customised versions. This manual is designed to enable the correct calculation of drives equipped with TEXROPE® synchronous belts. •TEXROPE® STB belt with STB trapezoidal tooth profile The TEXROPE® STB synchronous belt with trapezoidal tooth profile provides a positive drive by the meshing of belt teeth into the pulley grooves, i.e. with no belt slip. The lightness of the belt and the fact that the working tension is only that necessary for the tractive force combined with zero lubrication requirements facilitate a simplified drive design, considerably reducing investment and maintenance costs. •TEXROPE SupraDrive™belt with round tooth profile ® •TEXROPE® ExtraDrive™ belt with curvilinear tooth profile •TEXROPE® LL open-ended belt with STB or HTD® tooth profile •TEXROPE® DF double-sided belt with STB or HTD® tooth profile This manual covers two calculation procedures: one for TEXROPE® STB, TEXROPE® SupraDrive™ and TEXROPE® ExtraDrive™ and one for TEXROPE® LL belts. It gives all the necessary information for a complete calculation procedure. Thanks to their superior performance, TEXROPE® STB, TEXROPE® SupraDrive™ and TEXROPE® ExtraDrive™ belts take a major place in this manual. CONSTRUCTION AND FEATURES • This synchronous belt with standard trapezoidal tooth profile is available in XL, L, H and XH profiles (The XXH profile is available on request). • The tensile member provides tensile strength with virtually no stretch. • The flexible rubber top cover protects the tensile cords. • The precision-moulded teeth provide optimum meshing. • The abrasion-resistant cover protects the teeth in their contact with the pulleys. • The covering also reduces noise. • The belt is resistant to commonly used oils and temperatures between -25°C and +100°C. • The meshing of the teeth prevents belt slip and speed variations, thus ensuring optimum synchronisation and a positive drive. • The absence of metal-to-metal contact and the flexible meshing of the teeth considerably reduce the noise of the synchronous system. • Complies with ISO standard 5296. 1 1 APPLICATIONS The positive belt drive, which uses the tension solely for tractive force, and the wide range of power levels covered by the TEXROPE® STB synchronous belt make drive systems more compact and efficient and reduce maintenance costs. This belt range covers all industrial positive drive applications from hand-held tools to automated production lines and includes machine tools and printing machines, etc. TEXROPE® synchronous belts are characterised by: •a positive drive with high positioning accuracy •capable of high linear velocity and a reduced inertia •a high efficiency (98%) due to a high flexibility and lower tension •no metal to metal contact reducing noise levels •no lubrication or retensioning (minimum maintenance) •a light and compact pulley/belt system TEXROPE® STB ordering code is composed as follows: 120-XL-037 120 XL 037 Pitch length (12") Pitch Width (code) ®: Registered trademark of the Gates Corporation. CHARACTERISTICS AND ADVANTAGES OF TEXROPE® SUPRADRIVE™ BELTS CHARACTERISTICS AND ADVANTAGES OF TEXROPE® EXTRADRIVE™ BELTS The tough synchronous TEXROPE® SupraDrive™ belts are suited for a wide range of applications. They offer superior performances on existing HTD® pulleys and transmit up to 30% more power than TEXROPE® STB belts. TEXROPE® ExtraDrive™ is a universal synchronous belt which covers a large power transmission range. It transmits up to 40% more power than former TEXROPE® HTD®150 belts. It is available in 8M and 14M pitches and can be installed on existing HTD® 8M and 14M pulleys. No need to replace the drive system, TEXROPE® ExtraDrive™ ensures a perfect fit. This belt offers savings in money and energy at reduced noise levels. In addition, TEXROPE® ExtraDrive™ allows more compact drives. CONSTRUCTION AND FEATURES 1 • The tensile member provides tensile strength with virtually no stretch. • The uniform distribution of stress guarantees an excellent tooth jump resistance. • Savings in money and energy. • TEXROPE® SupraDrive™ belts have a round tooth profile and are available in 8 mm and 14 mm pitches. • The teeth are made of a new rubber compound. They are very accurately spaced, engage precisely with the pulley grooves and have a high tooth jump resistance. • The pitch line is stable, thus ensuring a perfectly constant angular velocity. APPLICATIONS TEXROPE® SupraDrive™ 8M and 14M pitch belts can be used for drives up to 400 kW, for example fans, pumps, compressors, mowers, etc. TEXROPE® SupraDrive™ ordering code is composed as follows: 480‑8M‑20 480 Pitch length (mm) 8M 20 CONSTRUCTION AND FEATURES • The curvilinear tooth profile improves stress distribution, enhances load capacity and significantly reduces noise levels. • The belt's teeth are made of a new rubber compound. They are accurately pitched, engage precisely with the pulley grooves and have a high tooth jump resistance. • The anti-abrasion facing protects the contact surfaces and offers improved shear resistance and adhesion. • The glass fibre cords provide the belt with its excellent flex life and resistance to elongation. • It meets anti-static requirements (ISO 9563). 1 APPLICATIONS TEXROPE® ExtraDrive™ belts are suitable for industrial applications with a maximum power of 675 kW and for applications in explosive environments (silos, petrochemical industry, …). In addition, they allow more compact applications.

The service factor depends on the motor type, the application and the operating time. 2. CALCULATE THE DESIGN POWER Design power (Pc) = service factor (Fs) x absorbed power (Pa) (or motor power if Pa is not available - Pm) → Pc = Fs x Pa (or Pm) 3. DETERMINE THE BELT PITCH Go to the belt pitch selection guides on page 9. Where, the power rating and the speed ratio of the smaller pulley (highest speed) are used to select the most suitable. 4. CALCULATE THE SPEED RATIO Calculate the speed ratio by dividing the rpm of the faster shaft by the rpm of the slower shaft. rpm faster shaft R = rpm slower shaft The smaller pulley is installed on the faster shaft. As from this step onward, there are two possibilities: the use of standard or non-standard pulleys. A. STANDARD PULLEYS 1 Select the pulley and belt length In the centre distance tables, find the speed ratio that is closest to R and choose the centre distance that is nearest to your requirements. The belt length code is given at the top of the column. B. NON-STANDARD PULLEYS Pulley selection For the speed ratio selected, note the two pulleys that offer the required speed ratio. It suffices to take the minimum pulley diameter into account for each profile. This diameter is equal to the smaller pulley diameter of the standard pulley range. Theoretical belt length calculation For the given pulley diameter and required centre distance, the theoretical belt length is calculated with the following formula: Belt width correction factors Belt width (code) Width factors 40 55 85 115 170 1.00 1.50 2.50 3.48 5.29 Bold figures refer to standard widths.

If you have less than this, you have to make an adjustment (see page 94). 92 In the belt length tables, select the length closest to Lth. 93 1 Centre distance calculation Static tension The approximate centre distance is calculated as follows: E= Tst = 4L – 2 x π (D + d) + [4L – 2 x π (D + d)]2 – 32 (D – d)2 16 Tst=static tension P =power in kW V =belt linear velocity in m/sec E =centre distance L =belt length = velocity large pulley (rpm) x N x pitch 60000 The formula below allows to calculate the centre distance more precisely, but an iterative calculation has to be made. 1 E= 2 x sin where: ß = 2 x cos { ( ) ß 2 L– ]} [ Recommended deflecting forces π ß x (D + d) + (1 – ) x (D – d) 180 2 (D2 x– Ed ) Maximum deflection force: FdMax. = P x 60 (Newton) V Minimum deflection force: FdMin. = P x 25 (Newton) V Theoretical width factor calculation For the basic power rating, Pb (power rating at the intersection of the speed ratio row and the pulley column in the power rating tables), determine the belt theoretical width factor.

This width factor allows to determine the standard belt width for the application. 94 95 CALCULATION EXAMPLE Test with a 1778 mm belt Given Electric motor: 60 kW at 1460 rpm DriveN: machine tool Speed: 860 rpm Service: 16 to 24 h daily Normal torque Required centre distance: 530 mm Calculation of the theoretical centre distance E = 4 x 1778 - 2 x π (285.2 + 169.34) + [4 x 1778 - 2 x π (285.2 + 169.34)] 2 - 32 ( 285.2 -169.34)2 16 E = 528,8 mm This belt length allows a centre distance relatively near to the required centre distance.

Determine the belt pitch An 85 mm width belt has a width factor of 2.5. Determine the belt pitch using the belt pitch selection guide on page 9. In this example the design power exceeds the 8M belt capacities and we will have to use a 14M pitch belt. In order to optimise the drive, design will be done with a TEXROPE® ExtraDrive™ 14M belt. Note The same design with a TEXROPE® SupraDrive™ belt would have given a width of 170 mm. rpm faster shaft R = rpm slower shaft 1460 = = 1.69 860 Belt installation tension Statique tension per strand Tst = 600 x P = 600 x 60 = 2780 Newton V 12.95 A. Drive design with standard pulleys 1 In the centre distance tables on pages 76-81, you will find the combination of 38 and 64 teeth with a speed ratio of 1.68.

Span 1: FG = m x g 2. Calculate the effective tension Span 2: FG = M x g The diameter of the pulley is calculated by combining the required speed of movement and the speed of the motor. Design force = (see page 103) Minimum width factor = (Tas = allowable working tension) Minimum width factor < belt width factor (see the respective charts for the corresponding pitches) 4. Check the minimum breaking load Maximum belt tension = Te + installation tension in belt span (see “Engineering data” on page 118). Maximum belt tension x S2 < minimum breaking load S2 depends on type of application. For the minimum breaking load, refer to the respective charts for the corresponding pitches. 2 FG Fb Fb = m x b FG - Fb = M x (g - b) Fb = M x b 3. 1. Starting forces (fig. 3) Span 1: FG = m x g 4.

Determine the belt width FG Fa Fa = M x a Te = (acceleration force and deceleration force) + m x g x μ Total mass = 2 x mp(R) + mb + M Te = Max {Fa, Fb} + FR The lifting force (m x g) is zero. M FG + Fa = M x (g + a) 2. Deceleration forces (fig. 2) m span 2 Make a first estimation of the effective tension (Te) by taking only the mass of the weight (M) into account. M Fa = m x a Span 2: FG = M x g 1. Determine the belt pitch m FG - Fa = m x (g - a) span 1 span 2 Span 1: FG = m x g span 1 1. Starting forces (fig. 1) span 2 Mass M goes up span 1 mL span 1 1. Calculate the effective tension Fa = M x a 2. Deceleration forces (fig. 4) Span 1: FG = m x g Fb = m x b Span 2: FG = M x b FG - Fb = m x (g - b) FG + Fb = M x (g + b) Fb : M x b Te = span 2 – span 1 The highest value of effective tension Te is the one used for calculation. Rule of thumb: multiply the biggest mass of the system (m or M) by the sum of g and the biggest acceleration value (a or b). This gives you Te. 2. Determine the belt pitch Choose the belt pitch using the belt pitch selection guides on page 99. 3. Determine the belt width The diameter of the pulley is calculated by combining the required speed of movement and the speed of the motor.

Inaccurate manufacture or reboring may result in poor drive performance. Permissible tolerances for bore (∆A) and for outside diameters (∆DE) are important and are shown in the tables on this page. Pitch accuracy The table on this page shows the pitch accuracy tolerance (∆p).

Draft The maximum permissible draft is 0.01 mm per 10 mm of face width, but it must not exceed the outside diameter tolerance.

It ensures a minimum force on the slack strand, which allows a perfect meshing of the pulley grooves. The belt installation tension is defined by the functional requirements of the drive as well as by the service life and power ratings of the synchronous belt. The best installation tension is the one best corresponding to all requirements. The installation tension of endless belts is calculated according to the formulae on page 95. For open-ended belts, tests have proven that installation tension is 1.1 – 1.2 Te on the shaft, which corresponds to a tension force of 0.55 – 0.6 x Te on each strand. However, for the following two drives, you have to take into account a tension force of 1.1 – 1.2 x Te on each strand; 1. Omega drives 2. drives requiring a positioning accuracy and subject to frequent loads. Too high a tension could damage the shafts and lead to premature wear of the belt. Elongation of the belt can be reduced by using the minimum values of the recommended tensions. For lifting applications a tensile safety factor (S2) of at least 10 is normally recommended. In all cases the end user requirements should be complied with. a A b d D Def E Ed Fa Fb Fd FDes FdMax. FdMin.
