Abstract: The invention relates to a toothed wheel that has a function for compensating tooth flank play in a meshing engagement with a second toothed wheel, using a divided toothing, said toothed wheel having at least one split along which a first toothed wheel half comprising a first section of the divided toothing and a second toothed wheel half comprising a second section of the divided toothing are arranged so as to be able to rotate relative to one another, the toothed wheel halves being arrested relative to one another by means of an anti-rotation system which, when activated, prevents mutual rotation of the toothed wheel halves.
