Differential angular adjustment 1

Way to get small angular adjustment.

Relative angle between green gear and yellow cam can be adjusted by turning the cam and fixed by pink key.

N1: number of slots on the gear.

N2: number of slots on the cam.

If N1 = N2 = 6, minimum adjusted angle A = 360/N1 = 60 deg.

If N2 = N1 + 1, minimum adjusted angle B = 360(N1.N2) deg.

In this video: N1 = 6, N2 = 7, B = 360/42 = 8,57 deg.

Compare with ordinary way:

that needs large number of slots to get small adjusted angle.
