Howdy all! In some project I do,I need to design belt transmission,now the tricky part is: On the output of the belt,I have wheel that needs to turn at 700 rpm,and I need to deliver power of 6KW. Now the weird question:I need to design the belt transmission so I will have 20 percent power loss in the belt tranmission ! How do I approach such task? I cant' find any formula that tackles this particular task. Maybe I'll just limit the available transmitted power (given by H=(f1-f2)*V/33000)?But how I set the f1 and f2 forces? P.S. I also need the centers of pulleys to be at some given distance from each other ,does that help? Thanks in advance.
