Abstract
The invention relates to a device for support of an adjusting ring which encompasses at a distance a basically circular blade carrier, which adjusting ring is rotatable in the circumferential direction around a center axis which is identical with the blade carrier, in order to adjust radially extending blades of a ring of a turbo-engine, wherein a plurality of levers are provided between the blade carrier and the adjusting ring, which levers are distributed over the circumference, extend tangentially in each case, and which on their free ends have a rotatable roller in each case, which are rollable in the circumferential direction on the adjusting ring or on the blade carrier. According to the invention, the lever is tightly clamped on one side to disclose a wear-free and reliable device for support of an adjusting ring which encompasses at a distance a circular blade carrier.
