Double pitch chain

by | Jan 6, 2021 | Product Catalog

Generally, conveyor chains are operated for longer distances and at decrease speeds than transmission chains. Accordingly, while the pins, bushings and rollers are left unchanged, and the plate pitch is doubled to reduce the number of sprocket teeth engaged with all the chain to half, the dress in of pins, bushings and rollers is modest because the chain speed is reduced. Double Pitch Chains, conform to ANSI standard and “Ultimate Existence Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains can also be offered.
Double pitch chain with resin rollers
This can be a Double Pitch Chain with R Roller made from resin, which generates much less noise and lighter weight compared with steel rollers. So, the chain is appropriate for a conveyor program made to operate quietly and convey light-weight content articles. Since the parts apart from rollers are made of steel, the common tensile power of a resin roller chain is definitely the very same as that of a steel roller chain. On the other hand, the “maximum allowable load” of your chain must be stored reduce, as shown while in the following table, to prevent damage for the plastic rollers by the stress in the engagement with sprockets.
The “Allowable load of resin rollers” refers towards the allowable load acting when conveyed articles or blog posts press the resin rollers traveling about the floor surface this kind of as guid rails.
Huge roller (R) and smaller rollers (S)
Due to the fact double pitch chains are often utilised for conveying products on a horizontal floor, chains designed for this objective have improved roller diameter equal to that of single pitch chains with the same pitch for increased load capacity and reduced traveling resistance. These rollers with bigger outer diameter are termed “large rollers”, and also the standard rollers are called “small rollers”.
Within this catalog, big rollers are expressed as R Roller, and small rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as from the following illustration, dependant on the nominal amount of the single pitch chain it is actually determined by.
Connecting backlinks
To the connecting links of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller, the spring clip sort (R connecting website link) is conventional. For C2080H or more substantial, the cotter form (C connecting link) is common. Connecting hyperlinks with an attachment, top roller or side roller may also be readily available.
