Chains

Question 1

Pitch circ diam. chains

Answer 1

d = N p / pi

Question 2

Power adjustment factor eqs

Answer 2

Ps = f1 f2 P

Question 3

What is f1 in the Power adjustment factor eqs

aka

Answer 3

f1 = characteristic of driver vs characteristic of driven

aka application factor

Question 4

What is f2 in the Power adjustment factor eqs

what is the N1

aka

Answer 4

f2 = 19 / N1

N1 = no. of teeth on driver

aka tooth factor

Question 5

Arc of contact in rads for chains

Answer 5

θ1 = pi - 2 sin^-1[ (p(N2 - N1) / pi) / 2 c]

Question 6

Define pitch in chains

Answer 6

Length of one link

Question 7

Chain length in pitches eqs

How can you iterate to find the real length

Answer 7

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)
