Chains Flashcards
1
Q
Pitch circ diam. chains
A
d = N p / pi
2
Q
Power adjustment factor eqs
A
Ps = f1 f2 P
3
Q
What is f1 in the Power adjustment factor eqs
aka
A
f1 = characteristic of driver vs characteristic of driven
aka application factor
4
Q
What is f2 in the Power adjustment factor eqs
what is the N1
aka
A
f2 = 19 / N1
N1 = no. of teeth on driver
aka tooth factor
5
Q
Arc of contact in rads for chains
A
θ1 = pi - 2 sin^-1[ (p(N2 - N1) / pi) / 2 c]
6
Q
Define pitch in chains
A
Length of one link
7
Q
Chain length in pitches eqs
How can you iterate to find the real length
A
L = [N1 + N2 / 2] + 2C / p + [ ( N2 - N1 / 2pi )^2 p/C ]
Assuming a C value and then rounding to the nearest pitches (as you can’t have half a pitch for eg)
8
