I. Introduction1. Why preventive maintenance?When compared to chain drives (with constant lubricationproblems), or gear drives (with mechanical problems andhigh costs), belt drives are the most cost-effective and reliablemeans of power transmission. This reliability can however onlybe obtained when belts and drives are properly maintained.The potential for long service life is built into every Gates belt.When coupled to a regular maintenance programme, yourbelts and drives will run relatively trouble-free for a long periodof time. Always inspect belts and drives before they fail. Thiswill reduce costly downtime and production delays.This manual has been designed as aguide to help you install and maintainGates industrial belts, including standardV-belts, multi-ribbed belts and synchronousbelts. Through proper installation andmaintenance, the service life of your beltdrives will dramatically improve — reducingdowntime and production standstills.Sources of drive problemsImproper belt orpulley installationPoor drive designImproper belt storageor handlingDefective drivecomponentsEnvironmental factorsImproper drive maintenance2. Components of a goodmaintenance programmeA complete and effective maintenance programme shouldinclude following elements:• maintaining a safe working environment;• regular belt drive inspections;• proper belt installation procedures;• belt product knowledge;• belt drive performance evaluations;• troubleshooting.All these aspects will be dealt with in the different sectionsof this manual.2
II. A safe working environmentIt is common sense to establish a safe workingenvironment in and around your belt drives.Besides making maintenance easier, thefollowing precautions will ensure safety forthe operator.No loose or bulky clothing.Do not clutter area around belt drive.A properly guarded belt drive.A properly designed guard has following features:• it completely encloses the drive;• it is equipped with grills or vents for good ventilation;• the size of the openings must be adequate, i.e. small enoughto prevent "pinch points";• it is preferably equipped with an automatic shut-off devicewhich deactivates the drive as soon as the guard is removed;• it has accessible inspection doors or panels;• it can easily be removed and replaced if damaged;• where necessary, it should protect the drive from weather,debris and damage.1. Trained personnelAlways have trained personnel working on your belt drives.2. Always turn equipment offTurn off the power to the drive before you start working, evenif you are going for a brief inspection. Lock the control boxand tag it with a warning sign “Down for maintenance. Donot turn power on.” Keep the key in your pocket. For addedsafety, and if possible, remove fuses. Inspecting the driveusually involves watching the machine running - but nevertouch it before it stops.3. Check position of componentsMake sure all machine components are in a “safe” position.Place fly-wheels, counterweights, gears and clutches in aneutral position to avoid accidental movements. Alwaysfollow the manufacturer’s recommendations for safemaintenance practices.4. Wear proper clothingNever wear loose or bulky clothes (e.g. ties, loose sleeves,lab coats) around belt drives. Wear gloves when inspectingpulleys to avoid being cut by nicks or sharply worn pulleyedges.5. Maintain safe access to the drivesKeep the areas around the drive free of clutter, debris andother obstructions. Floors should be clean and free of oil anddebris to ensure good footing and balance of the operatorwhilst working on the machine.6. Drive guardsAlways keep drives properly guarded. Every beltdrive must be completely guarded while in operation.A makeshift, partial guard is often more dangerous, since itgives a false sense of security and encourages unsafe action.Besides being a safety asset, a good guard makes yourmaintenance job easier since it protects thedrive from outside damaging influences.7. Test runBefore you put your drive back into normaloperation, have a "test run" to check whethereverything functions normally. Make anyverifications necessary and take correctiveaction if needed.3
