ABSTRACT:
A double gear wheel of a turning device on printing presses comprises an adjustment gear wheel (4). On the adjustment gear wheel a conical seat (7) is formed, which conical seat (7) is engaged in a conical recess (9) formed on the corresponding stationary gear wheel (2), when the two gear wheels (2, 4) are clamped to one another by means of a clamping body (5). The double gear wheel described above has a compact construction, is easy to manufacture with a high degree of precision, and without the requirement for any additional elements essentially guarantees a frictional engagement which reliably prevents the mutual rotation of the two gear wheels (2, 4) during operation of the printing press, even on printing presses which consist of a large number of printing mechanisms.
