Double pitch chain

In general, conveyor chains are operated for longer distances and at lower speeds than transmission chains. Accordingly, while the pins, bushings and rollers are left unchanged, and also the plate pitch is doubled to reduce the quantity of sprocket teeth engaged with the chain to half, the put on of pins, bushings and rollers is small since the chain velocity is minimal. Double Pitch Chains, conform to ANSI standard and “Ultimate Lifestyle Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains may also be out there.
Double pitch chain with resin rollers
This can be a Double Pitch Chain with R Roller manufactured from resin, which generates significantly less noise and lighter bodyweight compared with steel rollers. Thus, the chain is ideal for any conveyor method designed to operate quietly and convey light-weight content articles. Since the elements aside from rollers are made from steel, the common tensile power of a resin roller chain may be the identical as that of the steel roller chain. Having said that, the “maximum allowable load” with the chain needs to be stored lower, as shown from the following table, to avoid harm to the plastic rollers by the pressure from the engagement with sprockets.
The “Allowable load of resin rollers” refers towards the allowable load acting when conveyed articles press the resin rollers traveling over the floor surface such as guid rails.
Massive roller (R) and compact rollers (S)
Considering the fact that double pitch chains are frequently utilized for conveying goods on a horizontal floor, chains made for this function have enhanced roller diameter equal to that of single pitch chains in the same pitch for increased load capability and lower traveling resistance. These rollers with larger outer diameter are referred to as “large rollers”, along with the regular rollers are known as “small rollers”.
In this catalog, substantial rollers are expressed as R Roller, and little rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as from the following illustration, according to the nominal amount of the single pitch chain it’s dependant on.
Connecting links
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 kind (R connecting hyperlink) is normal. For C2080H or more substantial, the cotter kind (C connecting website link) is common. Connecting backlinks with an attachment, top rated roller or side roller are also obtainable.
