GUIDE VANE RING AND TURBOMACHINE

摘要

The invention is directed to a guide vane ring for a turbomachine, in which a vane bearing is produced in the inner ring via platform plates of the vanes and reliability against disintegration is produced via journals that extend radially inward from the platform plates, as well as a turbomachine.

主权项

1. A guide vane ring (1) for a turbomachine, having a plurality of rotatable guide vanes (2) that are borne radially outward in the radial direction, and having an inner ring (4) for the radially inner stabilizing of the guide vanes (2), wherein each of the guide vanes has an inner platform plate (8), and by the cylindrical surface (12) of this plate, the vanes are guided by sliding in an uptake (14) of the inner ring (4), wherein a journal (10) extends radially inward from the platform plate (8) in each case, the journal having a minimum length (I) that is greater than a minimum depth (t) of the uptake (14), and being disposed without contact in a journal borehole (16) without relative axial offset, between the inner ring (4) and the guide vanes (2), this borehole passing through a bottom segment (18) of the respective uptake (14).
