DISTRIBUTOR FOR AN EXHAUST GAS TURBINE WITH AN AXIAL FLOW

摘要

The invention relates to a distributor (5) for modifying the position of the guide blades (6) of a turbocharger exhaust gas turbine with an axial flow. The guide blades (6) are located axially symmetrically to the turbine axis (1) in a flow channel (14) through which exhaust gas (15) passes and can be rotated about a radially guided axis (8), respectively, by a rotating device. A blade shaft (18) which is guided through a housing wall and radially outwards out of the flow channel (14) is joined to each of the guide blades (6). Said blade shaft (18) is mounted in such a way that the part that is guided outwards can rotate about the axis of rotation (8). The rotating device contains an adjusting ring (19) which is located outside of the flow channel (14) and which can rotate about the turbine axis (1) and an adjusting lever (20) which transmits a torque from the adjusting ring (19) to the blade shaft (18) of each guide blade (6). Said adjusting ring (19) is mounted with its outer side on rolling bodies which are each configured in the form of single-armed levers (27) and are rotatably mounted on a part of the housing wall that is configured as a support ring (16).
