V-belt can be converted
to Hutchinson ribbed belt.

WHY SWITCH FROM V BELT TRANSMISSION 
TO RIBBED BELT TRANSMISSION ?

Here are the main advantages of this conversion: 

THE EFFICIENCY OF THE TRANSMISSION

  • Higher power transmission by continuous and uniform cord. 

  • A larger contact surface than V belts.

Technical studies have revealed that at the same tension and with the same geometry the Poly V compared to V-Belt has an upper yield : it is situated on average around 98 %, a fact that reduces electricity consumption and the size of the motor.

THE COMPACTNESS OF THE TRANSMISSION

  • Higher transmission ratio 

Ribbed belt 1: 60 vs V belt 1: 20.
Avoids the need for staged pulleys. 

  • Reduced diameter of the pulleys

The minimum diameters of ribbed profiles are smaller than those of V-Belt profiles. 

  • Reduced weight of the transmission

No need for a tensioner. 

  • Reduced belt width for a given geometry and the same power transfer (small ribbed pulley).

Moreover, the Poly V can operate in flexion and counter flexion with the following benefits:

  • A single belt can drive several accessories: serpentine belt installation.
  • Driving accessories from the back of the belt. 

 

EFFICIENCY

Stable tension: compared to V-Belt no need for matching thanks to the monobloc belt and no differential flapping.

The aging of the belt does not result in any loss of power. 

 

COST REDUCTIONS

PURCHASE:

  • Reduced diameter and pulley width.
    Compared to V-Belt no need for a tensioner with the Flexonic®
  • Lighter transmission 
  • Reduced belt length 
  • No need for inertia flywheels in some cases 
  • Machining of pulleys is facilitating: the Poly V can be used on smooth pulleys (receivers).

MAINTENANCE:

  • Rapid set up : 1 PM Poly V can replace up to 25 SPB V belts. 
  • No need for matching 
  • Increased lifespan 
  • No need for re-tensioning and verification operations on the range of elastic belts 
  • The tension of the Flexonic® can be stabilised after just a few minutes in dynamic performance mode.
    Tension will not change throughout the lifetime of the belt.

TIME AND PRODUCTIVITY:
Simpler factory installation of the Flexonic®: time savings and productivity gains.

  • Installed on fixed center distance with standard grooved pulleys 
  • Automatic tensioning


OPERATIONS:

  • Reduced energy costs (better transmission effi ciency) 
  • Increased lifespan of the belt. 


STORAGE:

  • Standardisation and rationalisation of references.
