optichain-CC Chain Control – Automatic chain tensioning systemDesign and operationThe Optichain-CC standard construction consists of two shaped guidesconnected on either side by punched, adjustable bands.Because of the large radius of the shaped guides and because thetensioner rides directly on the chain it absorbs jerks and vibrations. Thisensures the chain runs smoothly and reduces noise and chain wear.The Optichain-CC requires no fixed mounting points and thereforeeliminates the need for complicated and expensive bracketry. The twospans of the chain drive are pressed towards each other by the twoguides. As the chain stretches the chain controller moves towards on ofthe two sprockets (where i =l 1 towards the smaller sprocket). Thisincreases the wrap of the chain on the sprocket which in turn takes up theadded length of the chain. The life of belts the chain and the sprocketsbenefits from the improved meshing.Optichain-CC offers the following advantages:● simple and quick installation● light weight● no mounts or brackets required● reduced chain and sprocket wear● correct and constant chain tension● economic componentsFurther more errors in axial alignment are compensated for by the guideswhich constributes considerably to the life improvement of both chainsand sprocket.CharacteristicsThe chain guides are made from ultra high modecular weight polyethylene(UHMW) with a very high degree of polymerisation. Due to its highmodecular weight this material combines several technically importantproperties desirable in this particular application:● strength (impact value) even at low temperatures● stability of shape in hot conditions● resistance to stress corrosion● resistance to friction at high temperatures● high degree of shock absorption● resistance to wearPlease ask for further information.107
