V Belt Alignment Process Description

1. V-BELT ALIGNMENT

2. BELT MISALIGNMENT & CORRECTION  Parallel Misalignment :  (A) Measuring parallel  Angular Misalignment:  (B) Using a straight edge  (C) Using a piece of string  Correct Alignment:  (D) Correct alignment means that the grooves of the pulleys are aligned

3. BELT ALIGNMENT  Accurate belt alignment can help to:  Increase bearing life  Increase machinery uptime, efficiency and productivity  Reduce wear on pulleys and belts  Reduce friction and thereby energy consumption  Reduce noise and vibration  Reduce costs of replacing components and machinery downtime

4. BELT REPLACEMENT & ALIGNMENT PROCEDURE

5. SAFETY FIRST  LOTO procedure to be followed

6. RELIEVE BELT TENSION  Loosen the drive and move the pulley closer together to facilitate the removal of the old belts and to insure installation of the new belts without damage

7. INSPECT DRIVE ELEMENTS  Inspect and replace faulty or damaged machine elements such as Pulley , worn bearing or bent shaft  Pulley should be cleaned

8. INSPECT SHEAVES  Pulley condition  Never install new belts without inspection of Pulley  Look for worn groove sidewalls, shiny Pulley groove bottom, wobbling and damaged Pulley

9. SELECT REPLACEMENT BELTS  Never mix new and used belts  Never mix belts from different manufacturer  Always replace with the right type of belt

10. INSTALLING NEW BELTS  Place the new belts on the pulleys  Do not force the belts on the pulleys by using:  S crew driver  By rolling the pulleys

11. CHECK SHEAVE ALIGNMENT  The straight-edge should make contact at two points along the outside perimeter of both pulleys  V-Belt pulley alignment should be within a tolerance of 0.624mm per 100 mm of drive center distance (span)

12. CHECK BELT DEFLECTION / TENSION  Belt deflection / tension should be 1.54mm per 100mm

13. CHECK BELT DEFLECTION / TENSION
