STRUCTURERibs: compound of high resistance elastomer drives the pulley by wedging in the grooves. Their geometry optimizes the contact surface.
Cord: Made of polyester or aramid; it is the belt’s textile reinforcement.
The polyester cord is suitable for most applications.
The aramid cord can handle greater tension and increase power transfer by around 30%. (Please contact us for more information about the dynamic properties of these two cord materials.)
Backing: the backing protects the cord and the radial stability of the monobloc structure. It can also transfer power onto the smooth pulley.
CHARACTERISTICS Molding process: less waste and guaranteed thickness consistency.
Signifi cant fl exion and counter fl exion capacity (minimum diameter = 9 mm/PH profi le).
Compounds available for temperature ranges from -45°C to +120°C (EPDM).
Improved linear speed (up to 80m/s).
Absorption of torque spikes.
Profi le complies with ISO9982 standard.
Possible use on smooth pulley (receiver)(transmission ratio > 4).
POWER RANGE From 0.1 kW to several hundred kW.

CONTACTS
The Poly V® is a power transmission belt featuring multiple longitudinal ribs.It transmits the torque by contact of the belt rib fl anks and the pulley grooves.
Its monobloc design guarantees: Compactness
Noise reduction Tension stability and reliability
High power transmission Reduced costs
POLY V®
THE BELT FOR ALL APPLICATIONS
COMPACTNESSThe Poly V® has been designed with a larger contact surface area than V belts or fl at belts.
NOISE REDUCTIONThe Poly V® is molded. Its profi le is regular and its thickness is constant. It has been sized to guarantee under 2% slipping. This results in:
Less temporary noise (start up, etc.).
Less chassis vibration.
No diff erential belt fl apping between V belts (a single Poly V® replaces several V belts).
Reduced noise levels (see opposite).
HIGH OUTPUTSmaller carbon footprint
Iso-tension and iso-geometry technical tests show that the Poly V® can achieve an output several percent higher: over 98%, which can reduce energy consumption and sometimes even engine size.
REDUCED COSTSBenefi ts:
Reduced diameter and pulley width.
Reduced belt length.
No need for inertia fl ywheels in some cases.
Machining of pulleys is facilitated: the Poly V® can be used on smooth pulleys (receivers).
Maintenance:
Rapid set up (1 Poly V® can replace up to 15 V belts).
No need for matching.
Increased lifespan.
Operating:
Reduced consumption due to high output.
TENSION STABILITY AND RELIABILITYThe uniform positioning of the cord across the entire width of the belt also guarantees tension stability and consistency.
No need for matching thanks to the monobloc belt.
No diff erential fl apping thanks to monobloc belt.
Reduced maintenance: no need to adjust the tension a� er the belt has been run in.
Increased lifespan (up to 4 times longer than a V belt).
The Poly V® works with identical power transfer and geometry and lower tensions than those required for V belts.
POLY V®
1 belt2 "standard" pulleys
Moreover, the Poly V® can operate in fl exion and counter fl exion with the following benefi ts:
A single belt can drive several accessories: serpentine belt installation.
Driving accessories from the back of the belt.
The Poly V® has multiple application benefi ts:
Improved transmission ratio is possible (Poly V® 1: 60 vs V belt 1: 20). Does away with the need for stepped pulleys.
Reduced diameters (diameters up to 9mm with the H profi le compared to 50mm with V belts).
Reduced belt width for a given geometry and the same power transfer (small ribbed pulley) .
