Definitions
- a baffle and damper assembly includes end plates for closing the opening between adjacent blade shanks, a connecting member extending between the end plates, retaining means to lock the assembly to its adjacent blades against the urging of centrifugal force, and at least one damper weight movably secured to the connecting member and adapted to bear against the blade platforms under the urging of centrifugal force.
- This invention relates to turbomachinery and, more particularly, to a combined damping and sealing arrangement for use in turbomachinery rotor assemblies.
- the invention herein described was made in the course of or under a contract, or a subcontract thereunder, with the United States Department of the Air Force.
- turbomachinery rotor assemblies of the type having a plurality of blades extending radially from a rotor wheel or disc, it is generally important that a seal be provided between the wheel rim and the blade platform to reduce fluid leakage axially across the wheel, so as to forestall efficiency loss of the turbomachine.
- US. Pat. No. 3,112,915 assigned to the assignee of this application, discloses a rotor assembly air baffle which includes axially spaced end plates which are interconnected by axially extending connecting members.
- the end plates close the space between adjacent blade shanks while one of the connecting members is suitably shaped so as to bear against the underside of weight of the baffle increases, the baffle may, under the urging of centrifugal force, assume a fixed position against one or both of the blade platforms. When this occurs, the damping function is lost or substantially dimished and, from a vibration standpoint, the baffle acts as an integral part of one or both of the blades.
- This invention is concerned with an improved air baffle structure which retains the advantageous features of the above-mentioned patent while avoiding the foregoing problem.
- One object of this invention is to provide an improved sealing and blade damping structure for use in a turbomachinery rotor assembly.
- Another object of this invention is to provide an air baffle for sealing between adjacent turbomachinery blade shanks which carries at least one damper weight which is movably affixed thereto and is adapted to bear against the adjacent blade platform, under the urging of centrifugal force, and clamp vibration through the mechanism of heat-producing relative slip.
- a baffle and damper assembly comprising spaced, axially facingend plates sized to generally close the opening between adjacent blade shanks in a turbomachinery rotor assembly, with a connecting member extending between and joining the end plates.
- Support means in the form of dovetails, are integrally formed with the connecting member adjacent each end plate and are sized for engagement with a dovetail slot which is cooperatively formed by oneor more axial corrugations projecting from each blade shank readily outwardly of the rotor disc periphery so as to retain the baffle and damper assembly against the urging of centrifugal force in the same manner that each blade is retained to the rotor disc.
- One or more damper weights are movably or floatingly secured to the connecting member in a position where they will bear againstthe underside of the adjacent blade platforms to provide the desired damping through themechanism of heat-producing relative slip.
- FIG. 2 is a cross-sectional view taken along lines 2- 2 of FIG. 1;
- FIG. 4 is an enlarged partial cross-sectional view of the baffle and'damper assembly of this invention taken along lines 4+4 of FIG. 2.
- a baffle and damper assembly 24 is provided between peripherally adjacent blades 14 to retard motive fluidleakage axially across the disc 12 in the area of thebladeshanks 19, and, at the same time,-to damp vibration between the blades 14 and between each blade 14 and the disc
- each baffle and damper assembly 24 includes spaced, axially facing end plates 26, 28 which are interconnected by an axially extending connecting member 30.
- the end plates 26 and 28, the connecting member 30 and the retaining means or dovetails 32 may be conveniently formed as an integral, cast member.
- the damper weights 40 may be formed with the legs 48 separated as shown by the dotted lines of FIG. 4. With the legs 48 so formed, each weight may be secured to the connecting member 30 by simply bending the legs 48 toward each other until the tabs 46 engage the slot 50.
