Corrected power P c is given by: (see table 1 page 6) which considers into account the P c = P C c The graphs gives a guiding criterion for the section of the belt. TRANSMISSION RATIO Transmission ratio is calculated as follows: n i = 1 D = n 2 d where D is the pitch diameter of larger pulley and d is the pitch diameter of the smaller pulley. 4

TECHNICAL CALCULATION Peripheral speed of the belts is determined by v = d n 1 19 If the drive being calculated is of the V/flat type (one V pulley and one flat pulley) it is necessary to find the corresponding pitch diameter of the flat pulley. The pitch diameter of the flat faced pulley is obtained by increasing its external diameter by the amount in millimetres shown in the following table: FLAT FACED PULLEYS - PITCH DIAMETER CALCULATION Z A B C D E 19 8 10 14 24 33 16 15 19 The face width of the flat pulley should be increased by twice the top width of the V-Belt selected. PITCH LENGTH OF THE BELT AND CORRECT CENTER DISTANCE Whenever the shaft center distance I is not predetermined by the layout of the drive, the optimum distance may be chosen as follows: (i+1) d 1<i<3 I +d³ 2 i>3 I D The pitch is determined by: L ~ =2 I+1,57 (D+d)+ (D-d)2 4I From the list of belt sizes, should be selected the belt pitch lenght Lp nearest to the value of L above calculated. Since L L p the center distance I may be varied by subtracting half L - L p. Therefore the effective center distance of the drive will be: I e = I- L -L p 2 NUMBER OF BELTS The basic performance P b is the power which a single belt transmits under the following conditions: i = 1 This configuration corresponds to 180 arc of contact belt on both pulleys; i 1 The difference of kw-rating P d is the power which the belt transmits in excess of P b because i 1 in service conditions. The actual kw-rating P a is the power which the belt transmits in operating conditions and is obtain ed by means of: P a = (P b + P d ) x Cg x C L Table 4 (see belt family pages) gives the values of P b according to and d (smaller diameter) and the values of P d according to and i. 5

TECHNICAL CALCULATION Table 2 (bottom of this page) and 3 (see belt family pages) give values of the coefficients Cγ and C L taking into account the operating conditions. The arc of contact g of the belt on the smaller pulley is determined by: γ = 180-57 D-d I e The number of belts Q necessary for the transmission of the power Pc is determined by: Q = P c P a The number of belts actually is obtained in general by rounding up Q to the next highest whole number.

TRANSMISSION RATIO The transmission ratio can be calculated as follows: n i = 1 1 = = 1,82 n 2 660 Considering diameter d = 0 for the smaller pulley, the pitch diameter of the larger pulley is: D = i d = 1,82 0 = 455 Peripheral speed of the belts is determined by d v = n 1 2 ; v = 0 1 = 15,7 m/s 19 19 BELT PITCH LENGTH AND CORRECT CENTER DISTANCE For i = 1,82 (i.e. 1<i<3) the center distance is given by: (i+1) I d +d so I = 610 4 The pitch of the belt is determined by: (D-d) L = 2 I+1,57 (D+d)+ 2 ; 4 I (455-0) 2 L = 2 610+1,57 (455+0)+ = 2344 4 610 From the list of belt sizes (see table on belt family pages), should be selected the belt pitch lenght L p nearest to the value of L previously calculated. The center distance I may be varied by subtracting half L -L p. Therefore the effective centre distance of the drive will be: L -L I e = I- p 2 Having selected B 91 (L p = 2355 ), the actual shaft center distance is calculated by: I e = 610-2344-2355 2 = 615,5 8

LENGTH MEASURING AND GROOVE PULLEYS BELT LENGTH MEASURING The first and easiest way for measuring the V-belt is by placing the belt on a flat surface, giving the belt a circular shape and finally measuring the internal L i by means of a measuring tape. Adding i and after e (see belt families pages) to this, it s possible to calculate respectively L p and L e. This measuring way is not very precise, even if practically easy and feasible with a tape only. The correct way for measuring the V-belt is by means of pulleys and dynamometer. The belt is put on 2 pulleys, specific for the family and size of the belt and having the same pitch diameter. One is fixed while the second can move on a linear graduated scale. Depending on the belt, a certain force is applied to the second pulley in order to put the complete system under tension. The correct force is tabled the relevant standards referring to the belt family. To stabilize the system, at least 3 rotations of the pulleys are required. The pitch L p is given by the pulleys pitch diameter D and center distance a in the formula: Lp = 2 a * D Subtracting i and adding e (see belt families pages) it s possible to calculate respectively L i and L e. GROOVE PULLEYS Groove pulleys for V-belts must be manufactured with care and be made of good quality steel or engineering cast iron. It is most important that the flanks of the grooves shall be perfectly smooth and show no visible sign of machining, that all sharp corners of the grooves shall be rounded off and chamfered and that the external diameter of the face shall be constant overall. All pulleys must also be statically balanced. Dynamic balancing is required for speeds over 30 m/second. Profile and dimension of pulley should be in accordance to DIN 2211, BS 3790, ISO, RMA depending on the belt relevant standard. In tha drawing are shown the main characteristics and dimensions of groove pulleys for V-belts (example referring to Oleostatic belts). lp k h α d e f = pitch width = minimum height of groove above the pitch line = minimum depth of groove below the pitch line = groove angle = pitch diameter = distance between the axes of the sections of two grooves = distance between the axis of the section of the outer groove and the rim of the pulley 10

LENGTH MEASURING AND GROOVE PULLEYS The use of idlers in V-belt drives is not recoended. However, due to particular drive requirements and limitations, use of idlers may be absolutely necessary. For using idlers, requirements are as follows: 1. Providing take-up for fixed center drives. 2. Turning corners (as in mule pulley drives). 3. Breaking up long spans where belt whip may be a problem. 4. Maintaining tension, when idler is spring-loaded or weighted. A power corretcion (see below) is required. OUTSIDE IDLER 1. An outside idler should be at least one and one-third times as large as the smallest pulley on the drive, unless drive has unusually large pulleys. 2. An outside idler must be flat and without any crown. 3. To find the face width of a flat idler (between flanges if flanged) add 1 ½ times the nominal belt top width to the face width of the grooved pulley used. 4. An outside idler pulley should be located as close as possible to the preceding pulley. This is because V-belts move back and forth slightly on a flat pulley and locating it as far away from the next pulley minimizes the possibility of the belt entering that pulley in a misaligned condition. 5. Idler pulleys should be located only on the slack side of a drive. Increased arc of cont. RECOMMENDED NOT RECOMMENDED INSIDE IDLER 1. An inside idler will decrease the arc of contact. 2. An inside idler should be at least as large as the smallest pulley on the drive, unless the drive has unusually large pulleys. 3. An inside idler should better be a grooved pulley. In alternative, flat pulleys can be used. 4. A grooved inside idler pulley may be located anywhere along the span, preferably so that it gives nearly equal arcs of contact on the two adjacent pulleys. 5. Idler pulleys should be located only on the slack side of a drive. Decreased arc of cont. RECOMMENDED NOT RECOMMENDED RATED POWER CORRECTION Because idlers impose an additional bending stress point on the V-belt, the transmittable power is reduced. The smaller the idler diameter, the greater the bending stress, which results in a greater reduction in rated power and belt life. To compensate this loss, the design power of the drive must be increased. The following table gives the approximate correction factors according to the number of pulleys in the drive. The normal power rating should be multiplied by this factor. No. of pulleys in drive 2 3 (one idler) 4 (two idlers) Rating Correction Factor 1,00 0,90 0,80 Note: As stated, the above listed factors are only approximate values and apply only when idler diameters and their location is in accordance with the above recoendations. 11

STORAGE MAINTENANCE AND USEFUL ADVICES HOW TO STORE BELTS In order to store V-Belts correctly, it is advisable to hang them on "saddles" or on large-diameter tubular brackets. This diameter should be at least ten times the height of belts cross section. Long belts can be stacked to save space, provided that they are correctly coiled (see figures). Short belts can be stored on shelves, but be aware that stacks should not be more than 300 high, as the bottom belts may be otherwise deformed. Finally, hooks and nails are unsuitable for suspending the belts. CONDITIONS OF STORAGE Rubber V-belts can be stored for several years without causing any performance or reliability loss. For a correct storage, some prescription have to be taken into account. - Environment The storage premises should be cool, dry and well ventilated but not draughty. - Temperature Storage temperature should be within +5 and +30 C. Lower temperatures causes stiffening in the belt but are accepted in the storage. In order to avoid damages in the startup, it becomes necessary to heat the belt up to around before making it run on the machine. Higher temperatures due to heating are to be avoided. Distance from heating sources should be at least 1 meter. - Light Belts should be protected from light, especially direct sunlight and artificial light with high ultraviolet rays (neon light). - Ozone Equipments generating ozone, like high voltage electrical machines or fluorescent light sources, should not be installed in the storage. Also combustion gases and vapours, that can cause ozone, should be avoided. - Chemicals Flaable materials, lubricants, acids and any other aggressive material should not be kept in the storage. Belts elastomers may be affected or even irreparably damaged by such agents. CLEANING Never clean V-belts. If you need, for any reason, to clean belts use a dry towel or one soaked with a glycerine/alcohol mixture in the ratio 1:10. Other solvents such as petrol or benzene must not be used. Sharp-edged objects must not be used for cleaning V-belts. 12

BELT INSTALLATION To ensure a long service life and high performances, it is important to design correctly the application and to take care of correct installation, maintenance and storage of the belt. A drive must be designed in such a way to make proper provision for both installation and tensioning of the V-belts. For this purpose a take-up device is necessary; a slide adjuster on the motor is recoended to simplify installation and permit optimum tensioning. Table 5 (see belt family pages) provides minimum variation of center distance permitted for installation and tensioning of the belts. X = Take up allowance y = Installation allowance I = Center distance Furthermore, the following rules must always be observed: Y 1) check the alignment of the drive pulleys; 2) make sure that the flanks of the grooves are clean; 3) adjust the tensioner to stretch the belts sufficiently; 4) check the tension (see following section); 5) check correct diameter for tensioning pulley; 6) protect belt from oil and other chemicals; 7) when installing belts, slack off tensioner and avoid using tools or implements which may damage the belts. X Pulleys with large diameters increase belt life. They must be statically balanced up to the speed of 30 m/s and dynamically balanced over this value. TENSIONING SYSTEM The satisfactory performance of a transmission equipped with V-belts depends on the correct fitting tension. It is therefore necessary to proceed in the following way, using the slide adjuster: Belt tension control by deflection method The approximate relation among deflection force, belt deflection and belt tension is given by: F T s _~ t 4 f Imposing a belt deflection f= t 64 the deflection force should be in the range F min _~F = T s 16 F max _~F = 1,5 T s 16 where: Symbol Unit Definition F N perpendicular deflection force f belt deflection t free span T s N/strand static belt tension (see page 9) t Belt tension control by vibration method Belt vibration frequency: F r = T s 4 m t 2 Symbol Unit Definition F r Hz natural frequency of belt m kg/m specific belt mass t m free span T s N/strand static belt tension (see page 9) 13
