[0002] The accessory bracket is generally installed on the flange edge of the casing and is used to support the pipeline components, actuation components and other aero-engine accessories outside the casing. The aero-engine accessories are complex in structure and heavy in mass. The accessory bracket is subjected to a large static load, and superimposed with the vibration load in the engine working state, fatigue cracks are likely to occur, resulting in the fracture failure of the accessory bracket and the dropping of the accessories. For example, the Active Clearance Control component of the high-pressure turbine is welded by multiple sheet metal parts, and the configured accessory bracket has a long cantilever. Fatigue cracks and even fractures often occur in the accessory bracket and the internal structural parts of the accessory within a short service time, which does not meet the high-cycle fatigue life requirements of the engine.

[0065] Now, reference will be made in detail to the embodiments of the present invention, one or more examples of which are shown in the accompanying drawings. Each example is provided to explain the present invention, not to limit the present invention. In fact, it will be obvious to those skilled in the art that various modifications and changes can be made to the present invention without departing from the scope or spirit of the present invention. For example, features shown or described as part of one embodiment can be used with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover these modifications and changes that fall within the scope of the appended claims and their equivalents.

[0066] It should be noted that these and subsequent other drawings are only examples, which are not drawn under the condition of equal proportion, and should not be used to limit the actual protection scope required by the present invention.

[0067] The terms "first", "second", etc. can be used interchangeably to distinguish one feature from another, and are not intended to indicate that each feature must be located at the position shown in the drawings in each embodiment.

[0068] As Figure 1 and Figure 4 shown, the vibration damping support includes a hub mechanism 1, a frame mechanism 2, and a rope net 3. The hub mechanism 1 is connected to one of the vibration source and the vibration-isolated object. As Figures 3 to 5 shown, the hub mechanism 1 can be provided with a first adapter bolt 101. The first adapter bolt 101 protrudes from a housing 201 described later, is located on the axial side of the housing 201, and can be threadedly connected to an aero-engine accessory as the vibration-isolated object. A shoulder 102 can be provided at the root of the first adapter bolt 101. The shoulder 102 protrudes from the housing 201 described later, is located on the axial side of the housing 201. The shoulder 102 limits the vibration source / vibration-isolated object connected by the first adapter bolt 101 to have a gap with the housing 201, ensuring that the vibration source / vibration-isolated object connected by the first adapter bolt 101 does not collide with the housing 201 during the vibration process.

[0069] The frame mechanism 2 is connected to the other of the vibration source and the vibration-isolated object. As Figures 2 to 4 shown, the frame mechanism 2 can be provided with a housing 201. The housing 201 can be provided with a second adapter bolt 202. The second adapter bolt 202 protrudes from the housing 201 described later, is located on the other axial side of the housing 201 relative to the first adapter bolt 101, and can be threadedly connected to the flange of the casing as the vibration source. The second adapter bolt 202 can be provided on the axial end face of the housing 201. The second adapter bolt 202 can deviate from the center of the housing 201 to reduce the distance from the edge of the housing 201, avoiding interference between the edge of the housing 201 and the flange of the casing. An arc-shaped step 203 can be provided on the axial end face of the housing 201 where the second adapter bolt 202 is provided. The arc-shaped step 203 is in mating with the outer edge stop of the flange of the casing. The arc-shaped surface of the arc-shaped step 203 abuts against the arc-shaped outer edge of the flange of the casing to prevent the housing 201 from rotating relative to the flange of the casing.

[0070] As Figures 4 to 7 shown, a plurality of damping components 204 are provided around the frame mechanism 2. The plurality of damping components 204 can be circumferentially distributed. A plurality of rope mounting parts 103 are provided around the hub mechanism 1. The plurality of rope mounting parts 103 can be circumferentially distributed. As Figure 5 and Figure 6 shown, a plurality of rope segments 301 are provided around the rope net 3. The rope net 3 can be provided with a plurality of rope segments 301 in the circumferential direction. This makes the damping components 204, the rope mounting parts 103, and the rope segments 301 have consistency in the circumferential direction, and further makes the vibration damping effect of the vibration damping support have consistency in the circumferential direction.

[0071] As Figures 4 to 7As shown, each damping component 204 includes a movable chute 205 and a sliding member 206. Each movable chute 205 includes a first chute member 207, a second chute member 208, and a closing assembly 209. The groove portion 210 of the movable chute 205 is located between the first chute member 207 and the second chute member 208. The first chute member 207 is provided with a first groove wall 211, and the second chute member 208 is provided with a second groove wall 212. The first groove wall 211 and the second groove wall 212 are opposite to each other, and the groove portion 210 is located between the first groove wall 211 and the second groove wall 212. The sliding member 206 is supported to expand the first chute member 207 and the second chute member 208. The sliding member 206 is located in the groove portion 210. The sliding member 206 is provided with a first sliding wall 213 and a second sliding wall 214. The sliding member 206 is supported between the first chute member 207 and the second chute member 208. The first sliding wall 213 abuts against the first groove wall 211 and can slide relatively. The second sliding wall 214 abuts against the second groove wall 212 and can slide relatively. The sliding member 206 expands the first chute member 207 and the second chute member 208. The first chute member 207 and the second chute member 208 have a gap so that the first chute member 207 and the second chute member 208 have a stroke that can be closed by the closing assembly 209. The closing assembly 209 abuts to close the first chute member 207 and the second chute member 208. The closing assembly 209 can push one of the first chute member 207 and the second chute member 208 towards the other to close. The closing assembly 209 can also push the first chute member 207 and push the second chute member 208 to make the first chute member 207 and the second chute member 208 approach each other to close. The first chute member 207 and the second chute member 208 close to push the sliding member 206 to move in the first direction. When the first chute member 207 and the second chute member 208 close, the groove portion 210 is compressed, the first groove wall 211 and the second groove wall 212 approach each other, the first groove wall 211 pushes the first sliding wall 213 in the first direction, or the second groove wall 212 pushes the second sliding wall 214 in the first direction, or the first groove wall 211 and the second groove wall 212 simultaneously push the first sliding wall 213 and the second sliding wall 214 in the first direction respectively, thereby pushing the sliding member 206 to slide in the first direction. The sliding member 206 moves in the second direction to expand the first chute member 207 and the second chute member 208. The second direction is the reverse of the first direction. When the sliding member 206 moves in the second direction, the first sliding wall 213 pushes the first groove wall 211 in the second direction, or the second sliding wall 214 pushes the second groove wall 212 in the second direction, or the first sliding wall 213 and the second sliding wall 214 simultaneously push the first groove wall 211 and the second groove wall 212 in the second direction respectively. The first groove wall 211 and the second groove wall 212 move away from each other, the groove portion 210 is enlarged, and the first chute member 207 and the second chute member 208 are expanded.It can be understood later that the vibration triggers the sliding member 206 to slide in the second direction, overcoming the contraction of the contraction component 209 to cause the first slot member 207 and the second slot member 208 to be stretched open, and the contraction component 209 contracts the first slot member 207 and the second slot member 208, pushing the sliding member 206 to slide in the first direction, thereby causing the sliding member 206 to slide back and forth in the slot 210 to form damping and achieve vibration reduction.

[0072] like Figures 4 to 7 As shown, each rope segment 301 connects the sliding member 206 and the rope mounting portion 103, each rope segment 301 is connected to the sliding member 206 at one end and connected to the rope mounting portion 103 at the other end, and the rope net 3 composed of multiple rope segments 301 connects the hub mechanism 1 and the frame mechanism 2, supports the hub mechanism 1 at the center of the frame mechanism 2, and the hub mechanism 1 is supported on the frame mechanism 2 only by the rope net 3. The rope net 3 is elastic, and when the vibration source vibrates, the vibration source reciprocates with a small displacement relative to the vibration-isolating object, thereby triggering the hub mechanism 1 to reciprocate with a small displacement relative to the frame mechanism 2. In at least part of the stroke of the hub mechanism 1 reciprocating with respect to the frame mechanism 2, the rope segment 301 is pulled by the hub mechanism 1 and the frame mechanism 2, and the rope segment 301 pulls the sliding member 206 to move in the second direction, triggering the sliding member 206 to reciprocate and slide in the groove 210 to form damping, thereby achieving vibration reduction.

[0073] like Figure 5 and Figure 6 As shown, each rope segment 301 overlaps at least one other rope segment 301 to form damping by mutual friction. When the hub mechanism 1 reciprocates relative to the frame mechanism 2, the overlapping rope segments 301 in the rope net 3 rub to form damping to achieve vibration reduction.

[0074] The vibration-damping bracket is provided with two-stage damping vibration reduction, and the friction damping between the sliding member 206 and the movable slide groove 205 and the friction damping of the rope net 3 are used to achieve vibration reduction, thereby improving the vibration reduction effect and reducing the transmission of vibration load between the vibration source and the object to be isolated. The vibration-damping bracket is suitable for reducing the vibration load of six degrees of freedom. In addition, heat is transferred between the hub mechanism 1 and the frame mechanism 2 through the rope net 3. Due to the slender shape of the rope segment 301, the rope net 3 has a small heat transfer volume and a large heat transfer resistance, thereby reducing the transmission of heat load between the vibration source and the object to be isolated.

[0075] like Figure 4 , Figure 5 and Figure 7As shown, the first groove member 207 can be located on the axial side of the second groove member 208. The groove portion 210 is located axially between the first groove member 207 and the second groove member 208. The first groove member 207 and the second groove member 208 are axially closed and opened. This enables the multiple first groove members 207 of the multiple movable chutes 205 to be circumferentially adjacent to form an integral first disk member 215, the multiple second groove members 208 of the multiple movable chutes 205 to be circumferentially adjacent to form an integral second disk member 216, the multiple groove portions 210 of the multiple movable chutes 205 to be circumferentially independent of each other and be circumferentially distributed around the first disk member 215 and the second disk member 216. The multiple closing components 209 of the multiple movable chutes 205 can be circumferentially adjacent to form an integral component. Compared with setting multiple independent first groove members 207, multiple second groove members 208 and multiple closing components 209, the number of parts is reduced, the structure is simplified, and the integral closing component 209 closes synchronously at each circumferential position. The first disk member 215 and the second disk member 216 close and open synchronously at each circumferential position, and the multiple circumferential groove portions 210 are compressed and expanded synchronously, improving the synchronism and integrity.

[0076] As Figure 4 and Figure 7 shown, the damping component 204 can be located inside the housing 201. The housing 201 can be provided with an installation opening 217 on one axial side. The damping component 204, the rope net 3 and the rope installation portion 103 of the hub mechanism 1 are installed inside the housing 201 from the installation opening 217, which is convenient for installation. The housing 201 can be provided with an axial end wall 218 on the other axial side. The outer peripheral wall of the second disk member 216 can be attached to the inner peripheral wall of the housing 201, and the axial end wall of the second disk member 216 can be attached to the axial end wall 218 of the housing 201 and be axially supported by the axial end wall 218 of the housing 201. The axial end wall 218 of the housing 201 can be provided with a plurality of sector-shaped bosses 219 circumferentially distributed on the inner wall surface. The sector-shaped bosses 219 can axially protrude from the inner wall surface of the axial end wall 218 of the housing 201. The axial end wall of the second disk member 216 can be provided with a plurality of sector-shaped grooves 220 circumferentially distributed. The sector-shaped grooves 220 can axially recess from the axial end wall of the second disk member 216. The sector-shaped bosses 219 are inserted into the sector-shaped grooves 220 to clamp the second disk member 216 and prevent the second disk member 216 from rotating circumferentially. The outer peripheral wall of the first disk member 215 can be attached to the inner peripheral wall of the housing 201. The first disk member 215 can be axially supported by the sliding member 206. The sliding member 206 is located axially between the first groove member 207 and the second groove member 208. There is an axial gap between the axial end wall of the first disk member 215 and the axial end wall of the second disk member 216 so that the first disk member 215 and the second disk member 216 have an axial stroke that can be axially closed by the closing component 209. Further referring to Figure 5, when the damping assembly 204, the netting 3, and the hub mechanism 1 are loaded into the housing 201 from the installation opening 217, the first disk member 215, the second disk member 216, and the sliding member 206 are clamped and fixed by the elastic tooling clamp 223. The two jaws of the elastic tooling clamp 223 respectively clamp the axial end wall of the first disk member 215 and the axial end wall of the sector-shaped groove 220 of the second disk member 216. An axial gap can be provided between the axial end faces of the sector-shaped boss 219 and the sector-shaped groove 220 to avoid the jaws of the elastic tooling clamp 223 and allow the jaws of the elastic tooling clamp 223 to withdraw radially from this axial gap after being installed in place. The elastic tooling clamp 223 is removed radially from the first disk member 215 and the second disk member 216.

[0077] As Figure 4 and Figure 7 shown, the folding assembly 209 can be provided with an elastic element 221, and the elastic element 221 pushes one of the first groove member 207 and the second groove member 208 against the other. The circumferentially adjacent folding assembly 209 can be provided with a corrugated spring 222. The corrugated spring 222 can be fixed inside the housing 201, on the axial side of the first disk member 215, and abuts against the axial end face of the first disk member 215. The corrugated spring 222 is always in an axially compressed state and always axially pushes the first disk member 215 against the second disk member 216. The first disk member 215 and the second disk member 216 always have a tendency to axially fold. The circumferentially adjacent folding assembly 209 can also be provided with a snap ring 224 and an annular gasket 225. The snap ring 224 can be inserted and fixed in the annular groove of the annular side wall of the housing 201. The snap ring 224 protrudes from the annular side wall of the housing 201 towards the inner circumference. The annular gasket 225 is arranged axially between the snap ring 224 and the corrugated spring 222. The corrugated spring 222 abuts against the first disk member 215 on one axial side and abuts against the annular gasket 225 against the snap ring 224 on the other axial side, so as to be fixed inside the housing 201. The structure of the above folding assembly 209 is simple and reliable, and also presses the first disk member 215, the second disk member 216, and the sliding member 206 inside the housing 201 for fixation.

[0078] As Figure 4 and Figure 7As shown, the groove 210 can be provided with a large end and a small end, the size of the groove 210 at the large end is larger than the size of the groove 210 at the small end, and the distance from the first groove wall 211 to the second groove wall 212 at the large end is larger than the distance from the first groove wall 211 to the second groove wall 212 at the small end.

The second direction is from the large end of the groove 210 to the small end, that is, from the large end of the sliding member 206 to the small end. The sliding member 206 slides from the large end to the small end in the groove 210, pushing the first groove wall 211 and the second groove wall 212 away from each other, and the first groove member 207 and the second groove member 208 are spread apart. Further, the first disk member 215 can be located on the axial side of the second disk member 216, the first groove wall 211 and the second groove wall 212 can be axially opposite, the groove 210 is located between the first groove wall 211 and the second groove wall 212 axially, the axial dimension of the groove 210 at the large end is greater than the axial dimension of the groove 210 at the small end, and the axial distance from the first groove wall 211 to the second groove wall 212 at the large end is greater than the axial distance from the first groove wall 211 to the second groove wall 212 at the small end.

The second direction is from the outer circumference to the inner circumference, and the sliding member 206 slides from the outer circumference to the inner circumference in the groove 210, pushing the first groove wall 211 and the second groove wall 212 away from each other axially, and the first disk member 215 and the second disk member 216 are axially spread apart. The structure is simple and reliable.

[0079] like Figure 4 and Figure 7As shown, the first groove wall 211 and the second groove wall 212 can both be straight walls, the first groove wall 211 can be inclined toward the first side relative to the center line of the groove portion 210, the second groove wall 212 can be inclined toward the second side relative to the center line of the groove portion 210, the second side is the opposite side of the first side, forming the large end and the small end of the groove portion 210, and the groove portion 210 is roughly V-shaped. The first sliding wall 213 and the second sliding wall 214 can both be straight walls, the first sliding wall 213 can be inclined toward the first side relative to the center line of the sliding member 206, the second sliding wall 214 can be inclined toward the second side relative to the center line of the sliding member 206, forming the large end and the small end of the sliding member 206, and the sliding member 206 is roughly trapezoidal. The first slot member 207 and the second slot member 208 are retracted, the first slot wall 211 and the second slot wall 212 are close to each other, the first slot wall 211 pushes the first sliding wall 213, and the second slot wall 212 pushes the second sliding wall 214, so that the sliding member 206 slides in the first direction in the slot portion 210. The sliding member 206 slides in the second direction in the slot portion 210, the first sliding wall 213 pushes the first slot wall 211, and the second sliding wall 214 pushes the second slot wall 212, so that the first slot wall 211 and the second slot wall 212 are separated from each other, and the first slot member 207 and the second slot member 208 are spread apart. Compared with the push of a single set of walls, the simultaneous push of the two sets of walls has a larger driving force, a larger driving stroke, a better damping effect, and a better vibration reduction effect. In addition, the two straight walls fit together to facilitate relative sliding, thereby preventing the sliding member 206 from getting stuck in the slot portion 210. Further, the first disk member 215 may be located on the axial side of the second disk member 216, the first groove wall 211 may be inclined toward one axial side, the first sliding wall 213 may be inclined toward the same axial side, the second groove wall 212 may be inclined toward the other axial side, and the second sliding wall 214 may be inclined toward the same axial side. The inclination angles of the second groove wall 212 and the second sliding wall 214 may be greater than the inclination angles of the first groove wall 211 and the first sliding wall 213.

[0080] like Figure 4 and Figure 7 As shown, the groove portion 210 can be blocked on the outer peripheral side by the annular side wall of the shell 201, and the annular side wall of the shell 201 prevents the sliding member 206 from continuing to move toward the outer peripheral side. The groove portion 541 can be blocked on the inner peripheral side by the inner peripheral walls of the first groove member 207 and the second groove member 208, and the inner peripheral walls of the first groove member 207 and the second groove member 208 prevent the sliding member 206 from continuing to move toward the inner peripheral side. The inner peripheral wall of the sliding member 206 is spaced from the inner peripheral walls of the first groove member 207 and the second groove member 208, and the outer peripheral wall of the sliding member 206 is spaced from the annular side wall of the shell 201, so that the sliding member 206 has a stroke in the groove portion 210 that can slide in the first direction and the second direction.

[0081] like Figures 4 to 7As shown, each rope mounting portion 103 may be provided with an outlet 104. A rope segment 301 protrudes from the outlet 104 to connect to the sliding member 206. The outlets 104 of multiple rope mounting portions 103 may be located in the same plane, which restricts the multiple rope segments 301 led out from the multiple outlets 104 from approaching each other, so that the rope segments 301 overlap. The plane where the multiple outlets 104 are located coincides with the plane where the multiple sliding members 206 are located, which restricts the multiple rope segments 301 connecting the outlets 104 and the sliding members 206 from being located in the same plane and approaching each other, so that the rope segments 301 overlap. The outlets 104 of multiple rope mounting portions 103 may be located in the same radial plane, the multiple groove portions 210 may be located in the same radial plane, the multiple sliding members 206 may be located in the same radial plane, and the radial plane where the multiple outlets 104 are located coincides with the radial plane where the multiple sliding members 206 are located. This restricts the multiple rope segments 301 connecting the outlets 104 and the sliding members 206 from being located in the same radial plane. At this time, the rope segments 301 have the shortest length. When the vibration-triggering hub mechanism 1 moves axially relative to the frame mechanism 2, regardless of whether the axial movement direction makes the hub mechanism 1 approach or move away from the frame mechanism 2, the rope segments 301 are pulled to have a longer length, which will necessarily trigger the rope segments 301 to pull the sliding member 206 to move in the second direction, thereby triggering the sliding member 206 to reciprocate and friction-slide in the groove portion 210 to form damping. At the same time, it will necessarily trigger the overlapping rope segments 301 to form damping by friction, achieving vibration reduction.

[0082] As Figure 4 , Figure 5 and Figure 7 shown, the multiple outlets 104 are adjacent to form an integral slit 105. The size of the slit 105 is narrow, which restricts the multiple rope segments 301 led out from approaching each other so that the rope segments 301 overlap, and is convenient for processing. The slit 105 may be an annular slit, surrounding the outer periphery of the hub portion 106 of the hub mechanism 1 and may be recessed radially.

[0083] As Figures 4 to 7 shown, each rope mounting portion 103 may be provided with a rope winding portion 107. Further referring to Figure 6, a plurality of ropes 302 are arranged along the periphery of the rope net 3. One end of each rope 302 is connected to a sliding member 206, the middle part of each rope 302 bypasses and constricts the rope winding part 107, and the other end of each rope 302 is connected to another sliding member 206. One rope 302 is connected to two sliding members 206 at both ends, bypasses and constricts the rope winding part 107 in the middle. The rope winding part 107 divides one rope 302 into two aforementioned rope segments 301. The rope 302 can slide on the surface of the rope winding part 107. A plurality of rope winding parts 107 can be circumferentially distributed on the hub part 106. Each groove part 210 can extend substantially in the radial direction but deflect a certain angle relative to the radial direction to point to one rope winding part 107, so that the connected rope segments 301 are straightened. The two sliding members 206 connected by the rope 302 bypassed by each rope winding part 107 are located in two groove parts 210. Each rope winding part 107 corresponds to two groove parts 210. Every two groove parts 210 point to one rope winding part 107. The groove part 210 located on the clockwise side of the corresponding rope winding part 107 is called the first groove part 226, and the groove part 210 located on the counterclockwise side of the corresponding rope winding part 107 is called the second groove part 227. The first groove part 226 and the second groove part 227 are arranged at intervals in the circumferential direction. Starting from the second groove part 227 of one rope winding part 107 in the clockwise direction, first passing through the first groove part 226 of the rope winding part 107 adjacent to it counterclockwise, then passing through the second groove part 227 of the rope winding part 107 adjacent to it clockwise, and finally reaching the first groove part 226 of this rope winding part 107. This makes the rope segment 301 on the clockwise side of this rope winding part 107 cross-lap the rope segment 301 on the counterclockwise side of the rope winding part 107 adjacent to it clockwise, and the rope segment 301 on the counterclockwise side of this rope winding part 107 cross-lap the rope segment 301 on the clockwise side of the rope winding part 107 adjacent to it counterclockwise, thus forming a rope net 3 with cross-lapped rope segments 301. The pointing of the groove part 210 can be achieved by Figure 5 the two parallel side walls shown.

[0084] As Figures 4 to 7 shown, a pin shaft 108 can be arranged on the rope winding part 107. The pin shaft 108 can penetrate through the hub part 106 and through the slit 105. A wear-resistant bushing is arranged on the shaft section of the pin shaft 108 located in the slit 105. The wear-resistant bushing is sleeved on the outer peripheral side of the shaft section of the pin shaft 108 in the slit 105. The rope 302 bypasses and constricts the wear-resistant bushing and can slide on the surface of the wear-resistant bushing to reduce the wear of the pin shaft 108. The rope 302 can be a metal rope, and further can be a steel wire or a superalloy wire. It can have a circular cross-section and can be coated with a wear-resistant coating at the overlapping position to reduce the wear of the rope 302. The rope 302 can be knotted at both ends and welded to the sliding member 206. The sliding member 206 can be made of L605 superalloy. As Figure 5 and Figure 6 shown, the hub part 106 can be provided with lace to facilitate the threading and weight reduction of the rope 302. All sharp edges of each part in contact with the rope 302 are rounded to prevent the rope 302 from being cut.
