A V-ribbed belt drive is composed of an endless belt with a longitudinally ribbed traction surface which engages andgrips, by friction, pulley grooves of similar shape. The belt ribbed surface fits the pulley grooves to make nearly total contact.
Poly Rib V Belt is ideal for high speed ratio drives with shortcenter distances, and it's quite compact with limited vibration.
Belt dimensions( mm)
Profile | PH | PJ | PK | PL | PM |
Rib pitch, Pb | 1.6 | 2.34 | 3.56 | 4.7 | 9.4 |
Rb min. | 0.3 | 0.4 | 0.5 | 0.4 | 0.75 |
Rt max. | 0.15 | 0.2 | 0.25 | 0.4 | 0.75 |
Belt Height,h ≈ | 3 | 4 | 6 | 10 | 17 |
NOTE Belt rib pitch and belt height are shown as reference dimensions only. Cumulative rib pitch tolerance is an important value, however, it is frequently affected by the tension at which the belt operates and the modulus of the tension member. | |||||
