GENERAL INFORMATION PRACTICAL ADVICE The reliability and longevity of a chain, whatever its application, depends not only on its own qualities and characteristics, but also on the care given to the design of the installation as a whole, as well as to its construction, lubrication and maintenance. GENERAL DESIGN OF THE INSTALLATION 1 – TRANSMISSION The centerline of the sprockets O1O2 should be horizontal or have a small inclination to the horizontal, Where the angle of inclination exceeds 60°, and where a vertical drive cannot be avoided, precautions must be taken to ensure proper chain-to-sprocket...

GENERAL INFORMATION PRACTICAL ADVICE 3 – CONVEYING • Number of teeth per wheel: conveyor chains generally have a pitch large enough to enable accessories to be fitted to the plates, hence the designer will want to reduce the number of teeth on the wheel in order to limit its dimensions. The polygonal effect becomes noticeable when the wheel contains 12 teeth or less, or perhaps more when the rotation speed is significantly high. For particular cases consult us. • Adjustment of shaft center: The shaft center should be adjustable in order to make chain assembly simpler, to adjust the slack on a...

2 - LIFTING • Defects in the alignment and parallelism of fixings and counter motion apparatus should be reduced as much as possible. 3 - CONVEYING • Defects in wheel alignment (with b1 : inner width of the inner link of the chain) : b1+2 for lengths below 10 meters and b1 for lengths above 10 meters • Defects in the parallelism of tooth plane:The wheels must be parallel (< 40'). • When two chains are working in parallel and are joined together with cross bars or with accessories, the chains should be ordered MATCHED. Lubrication 1 - THE ROLE OF LUBRICATION • To introduce lubricating fluid...

general information PRACTICAL ADVICE5 - WHERE LUBRICATING ? • Longitudinally, in an area where the chain load is low in order to help the lubricant penetration, • Transversally, between the plates to feed the lubricant towards the joints and between the inner plates, the rollers and the wheels. 6 - SUITABLE LUBRICANTS ACCORDING TO OPERATING CONDITIONS In general a good quality clean mineral oil, free from detergent is suitable. Its viscosity must suit the ambient temperature shown in the table hereafter. The operator must achieve a compromise between a low viscosity lubricant which would centrifuge...

GENERAL INFORMATION PRACTICAL ADVICE 3 – OPERATION Before starting-up, check: • the connecting link assembly, the fitting of spring clips with the closed end pointing in the direction of chain travel, that nuts are properly tightened and that there are no tight joints. • the absence of nuts, tools and spanners on the chain or trapped in the installation. Upon starting-up: • start off slowly and gradually, keeping a close watch during the first revolution or first cycle of the process, • run the drive under a light load or none at all for a while, • check the complete drive after a few hours or...

GENERAL INFORMATION PRACTICAL ADVICE CHAIN LENGTH ADJUSTMENT - SHORTENING If the installation does not involve adjusting the shaft center of the slack section, chain adjustment should be carried out either at the beginning, or after normal wear has occured. Leaf chains and conveyor chains do not contain offset link. Read directly «chains with an even number of pitches». Chains with an even number of pitches Chains with an odd number of pitches SHORTENING BY ONE PITCH ○ Chain up to and including 25,4 mm pitch. first remo- ve four pitches of chain from one end, that is two inners and two outers...
