#CMT# #/CMT# The system (61) has an annular balance clamp (52) with through passages (78), and a balance weight (54) mounted on the clamp by a screw/nut assembly (56) crossing the passages. The clamp has recesses (94, 98) on respective surfaces (90, 92) for each passage. The recesses pass through a radial top (80) of each passage and extend on both sides of a junction zone (74). The recess (94) is not in contact with a nut (88) and a screw head (86), where the nut and the head are supported against the surface (90). The recess (98) is not in contact with the weight supported against the surface (92). #CMT#USE : #/CMT# System for balancing a rotor of a module such as high pressure turbine and high pressure compressor, of a turbomachine (all claimed) e.g. jet engine, in an aircraft. #CMT#ADVANTAGE : #/CMT# The recess is not in contact with the nut and the screw head supported against the surface of the clamp, thus preventing the generation of axial constraints on passage's radial top stressed tangentially by centrifugal and thermal effects, and hence limiting the risk of deterioration of the clamp. The life duration of the clamp is therefore improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a rotor balancing system with balance weight and an assembling unit. 52 : Annular balance clamp 54 : Balance weight 56 : Screw/nut assembly 61 : Balancing system 74 : Junction zone 78 : Through passages 80 : Radial top 86 : Screw head 88 : Nut 90, 92 : Surfaces 94, 98 : Recesses. |
