Help with calculation for dynamometer build?

Click For Summary
Calculating the torque transferred to couplings and belts in a dynamometer build requires understanding the power and torque specifications of the system. The rollers have a diameter of 315 mm, with a maximum torque of 1000 NM and a power output of 1000 HP at 5000 RPM. The couplings and belt must be rated to handle the maximum power, which is 1000 HP, while the specific torque handling capacity needs clarification. Additional details, such as system drawings and specific coupling and belt types, will aid in providing accurate calculations. Clear communication of requirements and system specifications is essential for effective assistance.

I'm looking for someone who can help me calculate the torque there will be transferred to my couplings between the rollers and to my belt connecting the 2 set of rollers.
I have drawings of it all including inventor pro 2011 drawings/file of it all putted together without the belt and couplings.
The size of my rollers are 315 mm in diameter and the max torque the car will have is 1000 NM, so how much is my couplings and belt supposed to manage ?

Hope someone can help me, i have a few more questions that i will post afterwards :)

Thanks alot.

Lots of online calculators for belts & pulleys; This one seems relevant to your case given the little information you gave.

Just let me know what info you will need.

The first thing will be to know what you are actually looking for. The best that someone can tell you based on you original question, i.e.:

is to tell you that what will be transferred through your belt is power. So your couplings and belt must be able to handle 1000 hp. They usually also have some upper limits for rpm and torque. But those limits differ from pulley & belt types and from one manufacturers to another.
 
I'm looking to find the torque numbers my belt and couplings are supposed to manage.
The hp doesn't matter and the rpms are covered only the torque i need to know if possible?
 

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
