CHAINS AND SPROCKET

Question 1

Pitch Diameter, D

Answer 1

P/sin(180/T)

T = no. of teeth
P = pitch of chain

Question 2

Center Distance between Sprockets, C

Answer 2

(P/8)[2L - T - t + sqrt[(2L-T-t)^2 - 0.81(T-t)^2]

P = pitch of chain, mm
L = length of chain in pitches
T = no. of teeth of large sprocket
t = no. of teeth of small sprocket

Question 3

Length of Chain, L

Answer 3

2C + (T+t)/2 +(T-t)^2/40C

C = center distance in pitches
T = no. of teeth of large sprocket
t = no. of teeth of small sprocket
