DIVIDED TOOTHED WHEEL

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. When said anti-rotation system is activated, the first and second sections of the divided toothing at least approximately engage with one another in a flush manner whereas, when the anti-rotation system is not activated, said first and second sections of the divided toothing are arranged to be offset to one another, both sections being tensioned relative to one another by means of a resilient element, and the inactive anti-rotation system remaining in the toothed wheel while said wheel is in operation. The invention also relates to a method for installing a divided toothed wheel.
