ABSTRACT:
A device for adjusting a mutual phase relationship of respective rotational angles of two drive wheels, which are mounted on drive shafts parallel to one another and connected by a continuous transmission drive member to one another, the transmission drive member being deflectable so that the drive wheels are angularly set relative to one another, a first spanner being engageable with a slack strand of the transmission drive member, includes an adjusting lever for deflecting the tight strand of the transmission drive member, the adjusting lever being mounted swivellably with respect to a swivelling axis, and carrying the first spanner, and an adjusting device for swivelling the adjusting lever with respect to the swivelling axis and a spreading device including a guiding system for the second spaner, a spinning device for pressing the second spanner against the slack strand of the transmission drive member, and a counter-bearing for the spring device, the spreading device being braced against the adjusting lever by the spring device.
