ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Generally these chains are equivalent to ASME/ANSI common merchandise except the pitch is double. They are offered in Transmission Series, Conveyor Series with Standard (compact) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to reasonable speeds, minimal chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 for the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some companies usually do not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 etc. or 2040, 2050 and so on.
Conveyor Series with Normal (tiny) Rollers
This series is usually applied on light to reasonable load materials managing conveyors with or without the need of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. link plates in the up coming more substantial chain size. The chain number is identified by including 2000 for the ASME/ANSI chain number as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess huge rollers so that the chain rolls on the conveyor track cutting down friction. Chain numbers are uncovered during the same way as mentioned over except the last digit about the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Usually sprockets need to be created specially for these chains in accordance for the ASME/ANSI B29.3 and B29.four specifications nevertheless, for Transmission Series and Conveyor Series with Typical (compact) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may well be used presented the amount of teeth is 30 or a lot more.
