FIELD: machine tool manufacture, in particular, working of internal combustion engine cam shafts or parts having cams with similar or different profiles. SUBSTANCE: drive for irregular rotation of feeler spindle has set of pairs of noncircular tooth gears, with number of tooth gear pairs being equal to that of feeler spindle cams. Angular position of driven gear of each pair of tooth gears corresponds to that of one cam of feeler spindle. Torque is transmitted to drive output shaft through electromagnetic couplings, with number of couplings being equal to that of pairs of tooth gears. Construction of drive allows indexing mechanism to be obviated. EFFECT: simplified construction, wider operational capabilities and enhanced reliability in operation. 1 dwg
