Generally, conveyor chains are operated for longer distances and at reduced speeds than transmission chains. Accordingly, even though the pins, bushings and rollers are left unchanged, along with the plate pitch is doubled to reduce the amount of sprocket teeth engaged together with the chain to half, the wear of pins, bushings and rollers is compact because the chain velocity is low. Double Pitch Chains, conform to ANSI standard and “Ultimate Existence Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains are also obtainable.
Double pitch chain with resin rollers
This can be a Double Pitch Chain with R Roller made from resin, which generates significantly less noise and lighter weight compared with steel rollers. Hence, the chain is appropriate to get a conveyor system intended to operate quietly and convey light-weight posts. Because the components apart from rollers are manufactured from steel, the common tensile power of a resin roller chain will be the exact same as that of a steel roller chain. Nevertheless, the “maximum allowable load” of your chain need to be stored reduced, as shown from the following table, to prevent damage towards the plastic rollers by the stress from the engagement with sprockets.
The “Allowable load of resin rollers” refers on the allowable load acting when conveyed posts press the resin rollers traveling around the floor surface such as guid rails.
Massive roller (R) and little rollers (S)
Since double pitch chains are regularly utilised for conveying goods on a horizontal floor, chains designed for this function have elevated roller diameter equal to that of single pitch chains with the similar pitch for elevated load capability and lower traveling resistance. These rollers with more substantial outer diameter are called “large rollers”, along with the normal rollers are known as “small rollers”.
In this catalog, huge rollers are expressed as R Roller, and tiny rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as during the following example, based upon the nominal amount of the single pitch chain it can be based on.
Connecting links
For your connecting back links of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller sized, the spring clip style (R connecting link) is standard. For C2080H or greater, the cotter style (C connecting link) is typical. Connecting links with an attachment, major roller or side roller may also be obtainable.
