ABSTRACT:
An arrangement for positioning an inner circular machine part within an outer circular machine part, the parts being for example a guide vane carrier for a turbo-machine which is positioned within an outer housing, and wherein it is desired to adjust the inner machine part within a plane perpendicular to the longitudinal axis of the machine comprises cranked positioning keys which interconnect circumferentially spaced radial recesses in the periphery of the inner machine part with similarly circumferentially spaced non-radial recesses in the outer machine part. The keys are adjustably mounted in the non-radial recesses of the outer machine part, and the center line of the portion of each key engaging the radial recess forms an angle with the center line of the portion of each key engaging the non-radial recess. Longitudinal adjustment of the cranked key in the non-radial recess is provided by a spindle which threadedly engages the portion of the key in the non-radial recess, and the spindle is lockable against rotation by means of a lock nut on a threaded stem on the spindle which draws a collar on the spindle against a plate through which the stem passes, the plate being removably secured to the periphery of the outer machine part and closing off the non-radial recess. By removing the plate the cranked key can be withdrawn.
