Double pitch chain

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, as well as 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 conventional and “Ultimate Lifestyle Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains are also accessible.
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 fat in contrast with steel rollers. Therefore, the chain is appropriate to get a conveyor procedure made to operate quietly and convey light-weight articles. Since the components other than rollers are made from steel, the common tensile power of a resin roller chain is the same as that of a steel roller chain. However, the “maximum allowable load” of your chain really should be stored reduce, as proven from the following table, to avoid damage to the plastic rollers through the stress 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 around the floor surface this kind of as guid rails.
Huge roller (R) and little rollers (S)
Since double pitch chains are often employed for conveying products on a horizontal floor, chains built for this goal have increased roller diameter equal to that of single pitch chains on the similar pitch for increased load capability and lower traveling resistance. These rollers with more substantial outer diameter are termed “large rollers”, as well as the regular rollers are called “small rollers”.
On 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 from the following example, determined by the nominal variety of the single pitch chain it truly is dependant on.
Connecting back links
For the 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 style (R connecting link) is conventional. For C2080H or greater, the cotter form (C connecting link) is common. Connecting back links with an attachment, top rated roller or side roller can also be accessible.
