Double pitch chain

Normally, conveyor chains are operated for longer distances and at lower speeds than transmission chains. Accordingly, although the pins, bushings and rollers are left unchanged, as well as the plate pitch is doubled to reduce the amount of sprocket teeth engaged with the chain to half, the put on of pins, bushings and rollers is smaller since the chain velocity is lower. Double Pitch Chains, conform to ANSI common and “Ultimate Life Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains may also be obtainable.
Double pitch chain with resin rollers
This is a Double Pitch Chain with R Roller made of resin, which generates much less noise and lighter excess weight in contrast with steel rollers. So, the chain is ideal for a conveyor method made to operate quietly and convey light-weight articles or blog posts. Because the components apart from rollers are made of steel, the average tensile power of the resin roller chain would be the same as that of a steel roller chain. However, the “maximum allowable load” of the chain should be stored reduced, as proven inside the following table, to avoid injury to your plastic rollers by the pressure through the engagement with sprockets.
The “Allowable load of resin rollers” refers for the allowable load acting when conveyed articles or blog posts press the resin rollers traveling about the floor surface such as guid rails.
Big roller (R) and compact rollers (S)
Given that double pitch chains are frequently made use of for conveying goods on a horizontal floor, chains designed for this purpose have greater roller diameter equal to that of single pitch chains on the same pitch for improved load capability and lower traveling resistance. These rollers with greater outer diameter are called “large rollers”, plus the frequent rollers are referred to as “small rollers”.
In 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 within the following example, based upon the nominal number of the single pitch chain it truly is based upon.
Connecting backlinks
For that connecting back links of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller, the spring clip variety (R connecting hyperlink) is typical. For C2080H or larger, the cotter style (C connecting hyperlink) is typical. Connecting links with an attachment, prime roller or side roller may also be readily available.
