具有可轴向移动的导向叶片支架的轴流式涡轮机
摘要：
一种轴流式涡轮机，具有动叶栅；壳体(2)，动叶栅安装在所述壳体中；以及包围动叶栅的且集成在壳体(2)的内侧(3)中的导向叶片支架(19)，并且在形成径向间隙(12)的情况下，导向叶片支架(10)设置成直接相邻于叶尖(8)，其中导向叶片支架(10)平行于轴流式涡轮机(1)的轴线可移动地支承在所述壳体(2)中，并且所述轴流式涡轮机具有调节环(16)，所述调节环支承在壳体(2)和导向叶片支架(10)上且支承在接触面上，并且可围绕轴流式涡轮机(1)的轴线转动，其中，调节环(16)的和壳体(2)的和/或导向叶片支架(10)的接触面相对于与轴流式涡轮机(1)的轴线垂直的平面调整成，使得当调节环(16)围绕轴流式涡轮机(1)的轴线转动时，导向叶片支架(10)可通过调节环(16)轴向移动。
摘要（英）：

An axial turbomachine has a rotor-blade cascade, a housing (2) in which the rotor-blade cascade is installed, and a guide-blade carrier (19) which encloses the rotor-blade cascade and is integrated into the inner side (3) of the housing (2), and the guide-blade carrier (10) is arranged immediately adjacently to the blade tips (8) with the formation of a radial gap (12), wherein the guide-blade carrier (10) is mounted in the housing (2), such that it can be displaced parallel to the axis of the axial turbomachine (1), and has an adjusting ring (16) which is supported on contact surfaces on the housing (2) and on the guide-blade carrier (10) and can be rotated about the axis of the axial turbomachine (1), wherein the contact surfaces of the adjusting ring (16) and of the housing (2) and/or of the guide-blade carrier (10); are set with respect to a plane which is perpendicular to the axis of the axial turbomachine (1), in such a way that, when the adjusting ring (16) is rotated about the axis of the axial turbomachine (1), the guide-blade carrier (10) is displaced axially by the adjusting ring (16).
