On the whole, conveyor chains are operated for longer distances and at reduced speeds than transmission chains. Accordingly, although the pins, bushings and rollers are left unchanged, and also the plate pitch is doubled to cut back the number of sprocket teeth engaged using the chain to half, the put on of pins, bushings and rollers is little because the chain speed is low. Double Pitch Chains, conform to ANSI standard and “Ultimate Life Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains can also be readily available.
Double pitch chain with resin rollers
It is a Double Pitch Chain with R Roller made from resin, which generates significantly less noise and lighter bodyweight compared with steel rollers. Thus, the chain is suitable for any conveyor program intended to operate quietly and convey light-weight content articles. Since the parts besides rollers are made from steel, the common tensile strength of a resin roller chain will be the similar as that of a steel roller chain. Even so, the “maximum allowable load” on the chain ought to be kept reduced, as shown inside the following table, to prevent harm to your plastic rollers from the strain from the engagement with sprockets.
The “Allowable load of resin rollers” refers to the allowable load acting when conveyed posts press the resin rollers traveling on the floor surface such as guid rails.
Large roller (R) and tiny rollers (S)
Given that double pitch chains are regularly utilised for conveying solutions on a horizontal floor, chains created for this objective have enhanced roller diameter equal to that of single pitch chains of the similar pitch for improved load capability and lower traveling resistance. These rollers with bigger outer diameter are identified as “large rollers”, plus the standard rollers are known as “small rollers”.
In this catalog, large rollers are expressed as R Roller, and small rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as within the following illustration, based on the nominal number of the single pitch chain it truly is based on.
Connecting links
For your 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 type (R connecting hyperlink) is standard. For C2080H or greater, the cotter variety (C connecting link) is standard. Connecting hyperlinks with an attachment, leading roller or side roller are also obtainable.
