calculation of chain transmission forces

[Gigagighen]

Hello everyone,
I'm currently taking some weight to the current dynamis team single-seater.
my task is to remove as much weight from the back, more precisely differential compartment.
For this reason, I would like to have some opinions on the calculation of the forces deriving from the transmission of the chain that I need to replace the bearings with other lighter. I've already checked on the web, but I haven't found what I need, or complicated things or things that have nothing to do with it.

Thanks and I hope I haven't replicated another topic (I've already tried to look for but I haven't found anything that interests me!) :smile:

I don't understand anything, but you have a chain drive and you want to mount lighter bearings and you want to calculate the forces due to chain transmission.


Since I don't know what you're talking about if cars or trays move, I'd say if you want answers, you need to post a pattern of what you want us to analyze.


If you have only two axes with two crowns and a chain, I would say that the theory is written and very public domain. at the end there is the shooting speech on supports. It all works as a dented synchronous belt, where one branch is tense and the other is not. if you have speed and what variables you will get big bumps on the trees.


if all this is true and if possible by regulation replace with synchronous belt and aluminum pulley.



I guess it's something related to university.... the parallel world. for us working out, prototypes are other things, other problems, we build plants, industrial machinery, molds, there are those who make ships, etc. so give us more details, because in the end the mechanics is all the same.

especially thanks to the answer. You're right, but you see, I can't say everything openly because of copyright issues.
for this reason I will cease to make the matter as simple as possible:
This is a competition prototype, intended for competitions between Italian, European or world universities.
is a car with monocoque carbon frame and frame in rear frame connected to the monocoque through brackets and bolts; all for about 280kg car more pilot (paste plate more, pasta dish less:tongue.
to the rear wheel is bolted an opening motor sxv 550cc and the rear axle, consisting of differential support, eccentric for the regulation of the chain throw, from the turns bearings and from the solid crown to the differential but mounted to swing on the differential by means of a flange door crown.
the differential is connected by means of seeds trees to the wheels.

My problem is this: How do I calculate the forces that discharge on the differential bearings due to the transmission chain? since that is the force that urges differential support with its components.

I have done so: since there are 2 branches, one tense and the other lasco, I have taken as a reference model the method of calculation of the forces for the dentate straps, in which the forces that press the supports are due to tension in order to ensure the transmission of power and avoid slippages, which is equivalent to 3xforzatg (the one that gives moment).

here taking as reference this method, I have taken into account a force that stresses the supports of 1.5xforzatg(what gives moment).

What do you think? I don't need someone to make my calculations, but someone who can give me some tips
