The 14 sizes of common roller chains can be found ranging from 25 to 240 which includes those in conformity with ANSI (American National Standard Institute), and ISO (Global Organization for Standardization).
The chains not only meet the necessities for that minimum tensile strength prescribed by ANSI and ISO, nevertheless they also deliver the leading class high-quality in the planet which includes a substantial fatigue power
Appropriate uses
?Standard use for driving and lifting gear.
?Driving transfer units and other products. For multilevel parking.
Selection of chains
For choice of a chain, see the tables of “Max. Mixture CHAIN Horsepower Ratings” for standard roller chains and “Designing of Chain Transmission”. However, only for any exclusive case of minimal velocity and less shock, “Low-speed selection” system may also be referred to.
Typical roller chains up to five strands are available. The standard process for connecting pins and plates is rivet kind (RP).
The cotter kind (CP) is accessible for normal chains and HK chains of 80 or greater.
The common roller chains might be engaged with typical sprockets of the corresponding nominal numbers. For sprockets, refer to the table of “Dimensions” for every dimension of chain.
Connecting back links and offset links
For connecting back links and offset hyperlinks, refer on the table of “Dimensions” for each size of chain.
The connecting back links are generally R or C connecting back links by which the pins are clearance-fitted using the connecting plate. Because clearance-fitted hyperlinks are inferior towards the base chain in Max. allowable tension as during the case of one-pitch offset backlinks (OJ), “Low-speed selection” cannot be referred to. Because the Max. kilowatt ratings are decided contemplating the strength of connecting links and OJ, the clearance-fitted connecting backlinks and OJ may be made use of in case the chains are chosen according on the “General selection”. When a greater Max. allowable stress is needed for your connecting hyperlink, use the interference-fitted connecting website link (H connecting hyperlink) of the HI-PWR-S chain, and in the case of offset back links, use 2POJ.
