CARACTERISTIQUES GENERALES 10300 - 1/5 - 10/12 TECHNICAL DATA SHEET Flexible link connecting the motor to the machine to transmit heavy Endless V-belts composed: • (1) by natural and synthetic rubber in a balanced proportion assuring increased and constant dynamic priorities. • (2) by a kevlar cable with a high trading capacity, and a very limited deformation. • (3) a transverse fiber matress composed by two elastomer coated layers enabling a lasting maintaning of the cable in its optimal • (4) the dynamic bi-compound beltis made of an inverted junction on a double wrapping, separated by a rubber pillow coming from the CVT mixes (high elastic compression) General features • antistatic following standardNF T 47 104 • V belt sections following standard E 24 - 213 • resistant to oil projection, hydrocarbure and diluted acids. Approved by API (American Petroleum Institute) • enduring centrifugal strength • good draining of heat at high speed • linear mass: 0,367 kg/ml COLMANT CUVELIER On the VECO 300 EXTREME belt is clearly mentionned: -- the manufacture date (months and years code): 6C - the API mark previously cleared. - the pitch length measured under strength, as well as the: 5000 SPC - Length mark: figure and letter M_ et P_ - the set up of the belts: 3 distance marks as a maximum.

COURROIES VECO 300 EXTREME CARACTERISTIQUES GENERALES 10300 - 3/5 - 10/12 TECHNICAL DATA SHEET Estimate of the corrected power: Apply the power correction ratios below, according to the using frequency, fonction to the type of machine to tract, and of the nature of the driving power. The corrected power is: Pc = installed power x correction ratio. Calculation example: driver pulley = 0250 - =driven pulley = 250 x 2,52 = 0630 Calculating the transmission ratio: High shaft speed (rpm) Distances between axes: If the distance between axes E is not given, use as a minimum: - For a ratio less than...

COURROIES VECO 300 EXTREME® CARACTERISTIQUES GENERALES 10300 – 4/5 – 10/12 Determining drive belt length (L): The following formula must be used: (D - d)2 D+d Lo = 2 E + 3,14 + 4E 2 Calculation example: Lo = 2 x 1560 + 3,14 x (630 + 250)/2 + (630 - 250)2 /(4 x 1560) = 4625 mm Selected length L = 4500 mm Select je standard length L, which is the closest to the calculated length Lo. The new distance between axes thus becomes: L - Lo Lo - L E+ si L > Lo ou E si L < Lo 2 2 Determining the actual powe belt drive : Use the belt transmissible power tables (see technical data sheet n°10300 (5/5)) to...
