Circle1 with radius
intersects with Circle 2 with radius
. The Circle 1 has center
, and Circle 2 has the center
at the initial point. When the Circle 1 rotates with an angle θ, the Circle 2 that is attached to the Circle 1 change its coordination of the centre from
to$(-d\cos\theta, -d\sin\theta)$.

Not clear from the second drawing what the dl of interest is.
Let's assume dl is the distance between the left edge of each circle.
Then
d_l = -r_1 - (-d cos \theta - r_2)
Therefore
d_l / d_\theta = d sin \theta
