Abstract (en)

[origin: WO2010136018A2] The invention relates to a clearance control system for adjusting a running clearance (L) between a rotor (12) having rotor blades (10) of a turbomachine (14), especially a gas turbine, and a casing (18) which surrounds at least sections thereof and comprises at least two segments (16a-d). The clearance control system comprises at least one adjusting gear (20) which can be coupled to at least one segment (16a-d) of the casing (18) and which is used to radially move the at least one segment (16a-d) relative to a rotational axis (D) of the rotor (12) to adjust the running clearance (L), every segment (16a-d) of the casing (18) being coupled to at least three adjusting devices (20) of the clearance control system. The invention further relates to a turbomachine (14), especially a gas turbine, and to a method for adjusting a running clearance (L).
