发明名称 Guide vane ring of a turbomachine and associated modification method
摘要 A guide vane ring of a turbomachine, in particular of an axial-throughflow turbine, includes a vane group (6) having a plurality of vanes (2). The vane group (6) has a vane root (11) which has two flanges (12, 13). The vane group (6) is fastened to a vane carrier by means of the flanges (12, 13). In order to reduce stresses in the vanes (2) which occur during deformations of the vane carrier, one flange (13) has on a front end portion (14) and on a rear end portion (15), radially on the inside and radially on the outside, in each case a contact zone (18) which bears against the vane carrier. The other flange (12) has on one end portion (15), radially on the inside, a contact zone (18) which bears against the vane carrier, and is spaced apart from the vane carrier radially on the outside. Moreover, this flange (12) has on the other end portion (14), radially on the outside, a contact zone (18) which bears against the vane carrier, and is spaced apart from the vane carrier radially on the inside. Furthermore, the flanges (12, 13), between their end portions (14, 15), are spaced apart from the vane carrier radially on the inside and radially on the outside.
