Double pitch chain

On the whole, conveyor chains are operated for longer distances and at reduce speeds than transmission chains. Accordingly, although the pins, bushings and rollers are left unchanged, as well as plate pitch is doubled to reduce the amount of sprocket teeth engaged with all the chain to half, the put on of pins, bushings and rollers is compact since the chain speed is low. Double Pitch Chains, conform to ANSI regular and “Ultimate Existence 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 weight compared with steel rollers. Therefore, the chain is suitable to get a conveyor process made to operate quietly and convey light-weight posts. Since the components apart from rollers are made of steel, the average tensile strength of a resin roller chain is definitely the exact same as that of the steel roller chain. On the other hand, the “maximum allowable load” from the chain needs to be stored lower, as proven in the following table, to stop injury for the plastic rollers through the pressure from the engagement with sprockets.
The “Allowable load of resin rollers” refers for the allowable load acting when conveyed articles press the resin rollers traveling about the floor surface such as guid rails.
Huge roller (R) and modest rollers (S)
Given that double pitch chains are usually used for conveying goods on a horizontal floor, chains created for this goal have increased roller diameter equal to that of single pitch chains of the identical pitch for enhanced load capacity and reduce traveling resistance. These rollers with greater outer diameter are termed “large rollers”, plus the normal rollers are known 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 during the following example, according to the nominal variety of the single pitch chain it is based on.
Connecting hyperlinks
For 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 variety (R connecting link) is typical. For C2080H or greater, the cotter kind (C connecting link) is common. Connecting hyperlinks with an attachment, top roller or side roller can also be offered.
