Figure 3
Exploded view of the variable cam mechanism. The crystal (light cyan) rotates around axis R1, while the cam axis is R2. R3 is a moving axis defined by two flexure hinges and connects the cam to the oscillating table. Part A (pink) is the axis of the cam; the slit (S) on its front side is used to attach it to part B (blue). Part B moves up when part A moves towards the left of the picture. The DC motor used to rotate the cam is represented on the left (D). |
