ABSTRACT:
A wire ring bearing for an actuating guide apparatus for a gas turbine comprising two bearing rings concentrically arranged for relative motion with respect to one another between which is a plurality of rolling elements which are rollably supported on wire rings mounted in pairs respectively provided in circumferentially extending slots in the two bearing rings. One of the bearing rings comprises a plurality of individual ring elements which jointly define the slot in the corresponding bearing ring. A fastener secures the ring elements together with a spring interposed between the fastener and one of the individual ring elements. The fastener is engaged in a sleeve having a flange bearing against the head of the fastener and the spring has one end bearing against the flange and an opposite end bearing against the associated individual ring element. In this way any differential thermal expansions taking place between the individual ring elements will be taken up by displacement of the ring elements against the action of the spring thereby preventing stresses in the bearing which could interfere with movement of the other ring.
