Thanks to all of you your contributions. I should have also added that the chain drive is on a 45° slope and that I also have only 3" of space for the chain to fit. Please find attached the arrangement I currently have.
Thanks...
Thanks for your responses. Brian I have a problem with the motor bike procedure because it is very subjective. Different people will apply different forces and will consequently get different deflections. I want to specify the force so it doesn't vary from one technician to the other. This chain...
I have a roller chain that drives a mechanism. It actually rotates back and forth about 120°. I have a turnbuckle in the middle to allow for tensioning since it's not a continuous running chain and both sprockets are fixed. My question is how to specify the required tension to the assemblers and...
Thanks a lot for your responses. The turnbuckle seems like a nice idea. I just have to find a size which will work with a size 40 chain.
Thanks again guys.
Thanks Eromlignod. I have already checked the Mcmaster tensioner and its too bulky for my application. I dont have the space. My chain is not going to run continuous. I am only going to be moving back and forth over a 180° angle.
I need to use roller chain to operate a mechanism over a 41 inches center to center distance. Speed is almost negligible, but the force of operation is high. My center distance is fixed with no room for adjustment of chian tension. I will like to be able to find some adaptor for connecting the...
I have a part that sees a lot of impact and torsion during operation. I need to make this part out of some plastic or composite with dielectric strength in the range of 380-450v/mil and below are the anticipated mechanical specs:
Tensile strength: 25000-35000 psi
impact strength 20-30 ft-lb/in...
