Double pitch chain

Usually, conveyor chains are operated for longer distances and at decrease speeds than transmission chains. Accordingly, while the pins, bushings and rollers are left unchanged, along with the plate pitch is doubled to cut back the quantity of sprocket teeth engaged with the chain to half, the wear of pins, bushings and rollers is little since the chain pace is very low. Double Pitch Chains, conform to ANSI typical and “Ultimate Lifestyle Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains are also available.
Double pitch chain with resin rollers
This can be a Double Pitch Chain with R Roller made of resin, which generates less noise and lighter excess weight in contrast with steel rollers. So, the chain is suitable for any conveyor process developed to operate quietly and convey light-weight content articles. Because the components besides rollers are made of steel, the common tensile power of a resin roller chain is definitely the same as that of a steel roller chain. Nonetheless, the “maximum allowable load” in the chain really should be kept reduced, as proven inside the following table, to avoid damage towards the plastic rollers through the stress from your engagement with sprockets.
The “Allowable load of resin rollers” refers to the allowable load acting when conveyed articles press the resin rollers traveling about the floor surface this kind of as guid rails.
Big roller (R) and modest rollers (S)
Due to the fact double pitch chains are commonly applied for conveying goods on a horizontal floor, chains created for this objective have improved roller diameter equal to that of single pitch chains of the same pitch for elevated load capability and lower traveling resistance. These rollers with larger outer diameter are referred to as “large rollers”, as well as the standard rollers are referred to as “small rollers”.
On this catalog, large rollers are expressed as R Roller, and compact rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as from the following instance, depending on the nominal amount of the single pitch chain it’s depending on.
Connecting backlinks
To the connecting hyperlinks of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller sized, the spring clip type (R connecting link) is common. For C2080H or greater, the cotter style (C connecting hyperlink) is conventional. Connecting hyperlinks with an attachment, major roller or side roller are also readily available.
