Roller Ghain - Double pitch

169 Views, 6 Replies
07-02-2013 09:59 AM

I am using the Roller Cain generator to design a chain drive. I wish to use ASME B29.3 Double-Pitch Power Transmission Roller Chain #2050. The generator says the pitch is 1.125.

 

If I look up the same chain from US Tsubaki, they are giving me a pitch of 1.250.

 

Whos is correct?

 

I am using Inventor 2013.

 

thanks

I would go with the data from the chain supplier that you will be using.

In fact, I'm curious where they get 1.125 from, because 2040 is 1.0"...
