Double pitch chain

Generally, conveyor chains are operated for longer distances and at lower speeds than transmission chains. Accordingly, although the pins, bushings and rollers are left unchanged, plus the plate pitch is doubled to reduce the number of sprocket teeth engaged using the chain to half, the put on of pins, bushings and rollers is modest since the chain velocity is low. Double Pitch Chains, conform to ANSI conventional and “Ultimate Existence Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains are also obtainable.
Double pitch chain with resin rollers
It is a Double Pitch Chain with R Roller made of resin, which generates much less noise and lighter bodyweight in contrast with steel rollers. Therefore, the chain is appropriate for a conveyor system made to operate quietly and convey light-weight articles or blog posts. Because the elements other than rollers are made from steel, the average tensile strength of the resin roller chain will be the identical as that of a steel roller chain. On the other hand, the “maximum allowable load” with the chain should be stored decrease, as proven from the following table, to avoid damage on the plastic rollers by the strain through the engagement with sprockets.
The “Allowable load of resin rollers” refers for the allowable load acting when conveyed posts press the resin rollers traveling over the floor surface this kind of as guid rails.
Massive roller (R) and compact rollers (S)
Since double pitch chains are frequently made use of for conveying merchandise on the horizontal floor, chains intended for this function have greater roller diameter equal to that of single pitch chains from the identical pitch for improved load capacity and reduce traveling resistance. These rollers with bigger outer diameter are identified as “large rollers”, plus the common rollers are named “small rollers”.
In this catalog, huge rollers are expressed as R Roller, and little rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as during the following instance, based upon the nominal number of the single pitch chain it truly is based upon.
Connecting back links
For that connecting backlinks of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller sized, the spring clip kind (R connecting link) is conventional. For C2080H or larger, the cotter kind (C connecting website link) is regular. Connecting back links with an attachment, leading roller or side roller can also be available.
