Rotating component balance ring
A balance ring for a gas turbine engine has a ring shaped body with a first radial thickness, an anti-rotation tab extending outward from the body and at least one millable balancing feature connected to the body.
1. A method for balancing a rotating component of a turbine engine comprising the step of:
determining a weight profile of a rotating component of a turbine engine via empirical testing;
adjusting a weight profile of at least one balance ring by milling at least one balance ring counterweight of the at least one balance ring to a desired weight profile, wherein the desired weight profile counteracts an overweight region of the weight profile of the rotating component; and
connecting said balance ring to said rotating component such that said balance ring is maintained in a static position relative to said rotating component.
2. The method of claim 1 , further wherein the step of connecting said balance ring to said rotating component such that said balance ring is maintained in a static position relative to said rotating component comprises receiving an anti-rotation tab of said balance ring in an anti-rotation slot of said rotating component.
3. The method of claim 2 , further comprising the step of receiving a ring-shaped body of said balance ring in a balance ring retention groove of said rotating component.
4. The method of claim 1 , further comprising the steps of:
determining a weight profile of the overweight region of said rotating component; and
determining a weight profile of the at least one balance ring counterweight operable to counter the overweight region of said rotating component based on the weight profile of the overweight region.
