Pinion 7 rotates about fixed axis B and meshes with two racks, 11 and 12, which slide in fixed guides C-C and D-D. Rack 11 is integral with rack 9 which meshes with pinion 10. Pinion 10 is rigidly2 attached to disk 2 which rotates about fixed axis A. Rack 1 carries cam 8. Link 5 slides in guides F-F and carries roller 13 which rolls along the working surface of cam 8. Roll 4 rotates about fixed axis E-E. The rotation of pinion 7 is transmitted to disk 2 of the integrator and further through balls 3 held in carriage 14 to roll 4. Carriage 14 has supplementary traverse along a radius of disk 2 due to the action of cam 8 whose profile corresponds to the given function of the angle of rotation a₂ of the integrator disk: y=f(a₂). With no slippage, the instrument provides for the following relationship between the rotation of disk 2 and roll 4: α₄=α₄₀+(1/r₄)*∫(f(α₂))dα₂; with limits [α₂₀,α₂] where α₄ and α₄₀ are angles of rotation of roll 4 and r₄ is the radius of roll 4.
