Hollow shaft, hexagonal connection with hub. Materials and torque on the shaft are known and I'm trying to find out how big the diameters and hexagon length 'b' should be. Surface pressure between shaft and hub also.
Only formula I found was for max. torque, shown in picture. I'm not sure how...
Thanks for the formula, chicopee. I've already forgotten everything I learnt in school.
israelkk,
I have a very simple cylinder with a pile of disc springs inside. Number of springs and stacking order are known and always the same. The spring pile has to be pre-loaded to force F meaning that...
Thanks for help so far. Iteration is the easiest way and Schnorr handbook really contains a lot of information, but the equation is always used to calculate F.
I still wonder how the same thing is written 's=...' Looks simple, but after two hours of trying, no success.
Spring force equation for disc spring. F= spring force at deflection s. I know the spring force F and all the other values, but s is unknown.
How do you write the same equation: s=...?
You have my word for it ;) I haven't seen this kind of example in any book - it's always the p(max) which is calculated. I actually got this problem at work with real brakes. Nobody had ever thougt about how the surface pressure changes over the whole lining area.
There's also a more difficult...
Hi All,
I have a problem concerning band brake surface (contact) pressure. Formulas and examples are given in textbooks and they look simple, but direction of the forces is difficult to understand. I think the basic equation is called capstan equation and it's used often in rope and belt...
