ABSTRACT:
A stator arrangement, or distributor, for a turbine machine is disclosed which includes a guide blade. The blade shaft is supported to be able to pivot around the pivot axis, with a part which is to be guided being situated to the outside. The pivoting device contains a setting ring which is located outside a flow channel and which can be pivoted around the turbine axis, and adjusting levers which transmit torque from the setting ring to the blade shaft of each guide blade. The adjusting lever is slipped with one end onto the blade shaft. The other end can be configured as a ball head, the adjusting levers being guided in a groove of the setting ring. The surface which acts on the ball head of the adjusting lever for transmission of torque from the setting ring to the blade shaft of each guide blade can be configured as a ball socket. Exemplary embodiments can yield a uniform large-area pressure distribution by which the wear of the parts which press on one another can be distinctly reduced.
