Double pitch chain

Usually, conveyor chains are operated for longer distances and at decrease 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 using the chain to half, the put on of pins, bushings and rollers is tiny since the chain speed is reduced. Double Pitch Chains, conform to ANSI regular 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 is a Double Pitch Chain with R Roller made from resin, which generates significantly less noise and lighter fat compared with steel rollers. Therefore, the chain is suitable for a conveyor technique built to operate quietly and convey light-weight content articles. Since the components other than rollers are made from steel, the average tensile strength of a resin roller chain may be the same as that of a steel roller chain. On the other hand, the “maximum allowable load” with the chain ought to be kept reduced, as shown while in the following table, to prevent injury to the plastic rollers from the pressure in the engagement with sprockets.
The “Allowable load of resin rollers” refers to the allowable load acting when conveyed posts press the resin rollers traveling around the floor surface this kind of as guid rails.
Big roller (R) and modest rollers (S)
Considering that double pitch chains are regularly applied for conveying products on a horizontal floor, chains made for this goal have enhanced roller diameter equal to that of single pitch chains from the same pitch for enhanced load capability and reduce traveling resistance. These rollers with bigger outer diameter are identified as “large rollers”, as well as common rollers are referred to as “small rollers”.
In this catalog, big rollers are expressed as R Roller, and little rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as inside the following example, according to the nominal quantity of the single pitch chain it truly is according to.
Connecting links
For your connecting hyperlinks 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 regular. For C2080H or more substantial, the cotter form (C connecting hyperlink) is regular. Connecting backlinks with an attachment, best roller or side roller are also obtainable.
