Description

Method, device and system for reducing vibration of rotating system

The specific embodiments of the invention described herein are generally related to reducing vibration, and more particularly to a method, apparatus, and system for reducing vibration in a rotating system, such as a vehicle tire or a vehicle wheel.

Vibration is a major factor in rotating systems, such as vehicle wheels. Vibration negatively affects durability, ie service time as well as life, safety and comfort. Regarding safety, vibration has a direct impact on stability and can cause material fatigue and damage. Regarding comfort, vibration has a direct effect on noise and can increase the amount of noise. In addition, the vibration induced noise can be amplified by an integral system (eg, a vehicle) that includes the rotating system.
The rotating system can, for example, comprise a tire, a frame, a shaft, a bearing, a rotor, or a combination thereof. The main source of vibration in rotating systems is imbalance. The vibrations may comprise vibrations that are typically derived from the rotational speed of the rotating system. Vibration can damage the rolling element bearing (eg, ball or roller bearing) or seal used as, for example, a bearing.
In order to reduce vibration, the rotating system can be initially balanced by selectively removing material from or adding material to the rotating element of the rotating system during production of the rotating system such that its center of gravity (CofG) moves to It is the center of rotation of its pivot (CofR). Removing the material can include wiping (eg, grinding away) the material from the rotating element, or drilling a hole in the rotating element, or a combination thereof. Adding material can include attaching (eg, bonding) material to the rotating element. However, this removal or addition step is an additional step in production, particularly in mass production, requiring time and increasing cost.
In addition, vibrations in the rotating system generally increase over time due to wear and cracking of the rotating system, or accumulation of particles in the rotating system, such as dust. In more detail, due to wear and cracking of the rotating element, its CofG is away from CofR over time, resulting in an imbalance and vibration.

It can be used on the side of the frame without tires. When the frame edge is to be used, the tire is mounted on the side of the frame.
The frame edge can include more than one chamber. The chamber or chambers may extend along a portion of the perimeter of the rim. In the case where multiple chambers are present, the chamber does not need to be filled with the same amount of equilibrium gel.
The chamber can be U-shaped or C-shaped. The chamber is then closed at either end. The chamber can be closed by a cover that is bonded or welded thereto. Thus, the adapter can have a coverage of 100% to 75%, or 90% to 50% or 80% to 45%, or 75% to 25% or 50% to 15 at the center of rotation from which the chamber is located. % of the chamber around the perimeter of the frame.
The balancing material fills the chamber to the extent that the frame edges are sufficiently balanced. The exact amount can be accommodated considering the frame edge and the type of tire combination, for example considering the frame edge and the weight of the tire combination.
The chamber can be sealed when a quantity of balancing material is filled in the chamber. The amount of the balancing substance can be determined using a machine for determining the edge of the frame and the imbalance in the combination of tires.

Without vibration, the shake-density balancing material solidifies again and remains in its position. An amount of the balancing substance 2300 can be inserted into the rotating element 2000 during extrusion.

The opening (not shown) may be self-sealing, vulcanized, or closed by a seal (not shown) attached (e.g., bonded or vulcanized) to the rotating element 2000.

As shown on the right hand side, for a ratio R = 100%, the section can have= b₁₀₀= c₁₀₀/ pi of the diameter of the circle, and therefore with A₁₀₀=(a₁₀₀/ 2)²* pi = (c₁₀₀/ 2)²/ The maximum area of pi. While a circular cross section provides the largest possible area for a given perimeter, other shapes may be used, such as a rectangle, a rounded rectangle, a square, a semicircle, a bell, an ellipse, or an oval. However, the cross-sectional area is available from A₀toAnd continuously different. For example, as shown in the middle, the section can be A₅₀=(a₁₀₀/ 2)²* pi / 2 = (c₁₀₀/ 2)²Rounded rectangle of / (2 * pi) area. Although a rounded rectangular cross section is shown, other shapes can be seen, such as a rectangle, a square, a semicircle, a bell, an ellipse, or an oval.

As shown on the left hand side, for a ratio R = 0%, the section can have a₀= 0 width, b₀= b₅₀= b₁₀₀Fixed length, and therefore have c₀= 2*b₀= 2*b₁₀₀The perimeter and A₀= "Rectangle" of the smallest area of 0. As shown in the middle, for a ratio R = 50%, the section can have a₅₀= a₁₀₀/ 2 width, b₀= b₅₀= b₁₀₀Fixed length, and therefore have c₅₀= 2*(a50 +b50)= a₁₀₀+ 2* b₁₀₀The perimeter and A₅₀= a₅₀* b₅₀= A₁₀₀/ 2 area of the rectangle.

As already described, the rotating system 1000 can be a vehicle tire. The rotating system 1000 can also be a vehicle wheel that includes a vehicle tire and a rim, and the rotating elements 2000, 2010 can be attached (eg, bonded, vulcanized, or welded) on the inside of the rim, the rim On the outside, toward the frame edge of the vehicle tire or toward the frame edge of the rotating shaft 2400. Furthermore, the invention is applicable to any rotating system, including the following (only a part of which) rotating system: an aircraft, such as an aircraft or a rotorcraft such as a helicopter; an object handler such as a washing machine, a washer-dryer, or a dryer , for example, a tumble dryer or a dehydrator; a power transmission system of an engine or motor system or a vehicle (such as a car); an engine, a power train or a power unit, or a wheel set of a linked vehicle; a vessel, such as a ship, such as a cargo ship; Tools such as power tools or machine tools; fans; or power generators such as generators.
In the test series, the vehicle tire 1000 has been adapted according to the modified embodiment of the invention shown in Figure 17. The vehicle tire 1000 is the brand Dunlop (www.dunloptires.com), model Sp Sport Maxx GT, size 96/Y. The first rotating element 2000 and the second rotating element 201 are bicycle brand Schwalbe (www.schwalbe.com), model 26" AV12 32/47-559/97, size 26 x 1,75 inches, having a width of approximately 0.9 mm Wall thickness. Viscose 3000 is the brand RENI-GmbH (www.renia.com), type Colle de Cologne.
Figure 22 shows the time (t) of the vehicle tire (#1) without any balancing system in seconds (s), and the vehicle tire (#2) with metal weight in seconds (s) The time (t) of the unit, and the demonstration of the acceleration (a) of the modified vehicle tire (#3) with two complementary rotating elements without balancing matter with time (t) in seconds (s) It is indicated that the acceleration (a) is accelerated by weight (g) in the pressurizing direction (ie, close to 9.81 m/s).²Acceleration. This representation is derived from experimental data taken at a rate of approximately 1 1/s and up to 240 s coverage.
As indicated by #1 in Figure 22, tires without any balancing system have been tested. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases to approximately 0.04 g and peaks at approximately 0.06 g. From about t = 30 s to about t = 150 s, the peripheral speed is maintained at this level, and the acceleration a is maintained at about 0.055 g. From about t = 150 s to about t = 210 s, the peripheral velocity is reduced to 0 km/h, and the acceleration a is reduced, reaching a peak to about 0.055 g and becoming smaller. This peak is caused by the resonance of the test device (not shown) during acceleration and deceleration.
It is indicated by #2 in Fig. 22 that the tire having the metal weight has been balanced and tested. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases to approximately 0.045 g and peaks at approximately 0.045 g. From about t = 30 s to about t = 150 s, the peripheral velocity is maintained at this level, and the acceleration a is maintained at about 0.04 g. From about t = 150 s to about t = 210 s, the peripheral velocity is reduced to 0 km/h, and the acceleration a is reduced, reaching a peak to about 0.07 g, 0.045 g, and 0.045 g and becoming smaller. This peak is caused by the resonance of the test device (not shown) during acceleration and deceleration.
As indicated by #3 in Fig. 22, the two supplemental rotating elements 2000, 2010 have been used without modifying the tire to modify the tire. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases to approximately 0.045 g and peaks at approximately 0.06 g. From about t = 30 s to about t = 200 s, the peripheral speed is maintained at this level, and the acceleration a is maintained at about 0.065 g. From about t = 200 s to about t = 240 s, the peripheral velocity is reduced to 0 km/h, and the acceleration a is reduced, reaching a peak to about 0.15 g and 0.06 g and becoming smaller. This peak is caused by the resonance of the test device (not shown) during acceleration and deceleration.
A comparison of #1 and #2 shows that the balance tire with metal weight will accelerate from 0.055 g to 0.04 g, so vibration can be expected.
A comparison of #1 and #3 shows that the tire 1000 modified by adding two supplemental rotating elements 2000, 2010 without a balancing substance will increase the acceleration from 0.055 g to 0.065 g, so vibration can be expected.
Subsequently, each chamber 2100, 2110 has been filled with 150 g of a shake-balanced substance by an opening (not shown) in the rotating elements 2000, 2010, the shake-density balancing substance comprising 97% by weight according to the international patent application The balance material of composition No. 6 in Table 1 of PCT/EP2009/065058, and 3% by weight of polytetrafluoroethylene (PTFE) nanoparticles according to International Patent Application No. PCT/EP2010/065125. The opening (not shown) has been closed using a seal 2600 that is bonded to the rotating element 2000, 2010. However, this amount of the balancing substance is not uniformly distributed after filling.
Figures 23 through 27 show an exemplary representation of vehicle tires with two supplemental rotating elements accelerating over time in five consecutive cycles, each supplemental rotating element containing the amount of balancing material. This representation is derived from experimental data taken at a rate of approximately 1 1/s and up to 360 s coverage.
Figure 23 shows an exemplary representation of acceleration of the vehicle tire with two supplemental rotating elements over time in the first cycle, each supplemental rotating element at the same ratio as in Figure 22 (#4-1( 0.0-0.15)) and the balance substance of this amount is contained in another ratio (#4-1 (0.0-0.6)) reduced by the factor of four.
For the first cycle, indicated in #23 in #23 (0.0-0.6), tires having two supplemental rotating elements 2000, 2010 have been tested, each supplemental rotating element containing this amount of balancing substance 2300, 2310. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases and peaks at approximately 0.55 g. From about t = 30 s to about t = 330 s, the peripheral velocity is maintained to this extent, and the acceleration a decays exponentially from about 0.58 g to about 0.12 g. From about t = 330 s to about t = 360 s, the peripheral speed is reduced to 0 km/h and the acceleration a is reduced to a peak of about 0.08 g.
For convenience, #4-1(0.0-0.15) also shows the first period in Fig. 23 in the same ratio as in Fig. 22; however, the acceleration above 0.15 g is outside this presentation.
The peak is caused by the resonance of the test device (not shown) during acceleration and deceleration. The decay of the index is caused by the rapid distribution of the rheologically balanced material in the chamber.
Figure 24 shows an exemplary representation of the acceleration of the vehicle tire with two supplemental rotating elements over time in the second cycle, each supplemental rotating element containing the amount of balancing substance in the same ratio as in Figure 22 (#4-2).
In Fig. 24, #4-2 indicates a second period of testing with two tires supplementing the rotating elements 2000, 2010, each supplemental rotating element containing the amount of balancing substance 2300, 2310. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases and peaks at approximately 0.09 g. From about t = 30 s to about t = 330 s, the peripheral velocity is maintained to this extent, and the acceleration a is slightly reduced from about 0.11 g to about 0.105 g. From about t = 330 s to about t = 360 s, the peripheral speed is reduced to 0 km/h, and the acceleration a is reduced to a peak of about 0.07 g.
The smaller peak than before is caused by the resonance of the test device (not shown) during acceleration and deceleration. The reduction is caused by the further distribution of this amount of shake-balanced material in the chamber.
Figure 25 shows an exemplary representation of the acceleration of the vehicle tire with two supplemental rotating elements over time in the third cycle, each supplemental rotating element containing the amount of balancing substance in the same ratio as in Figure 22 (#4-3).
In Fig. 25, #4-3 indicates a third period of testing with two tires supplementing the rotating elements 2000, 2010, each supplemental rotating element containing the amount of balancing substance 2300, 2310. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases and peaks at approximately 0.07 g. From about t = 30 s to about t = 330 s, the peripheral velocity is maintained to this extent, and the acceleration a is slightly increased from about 0.08 g and then decreased to about 0.065 g. From about t = 330 s to about t = 360 s, the peripheral speed is reduced to 0 km/h and the acceleration a is reduced to a peak of about 0.04 g.
Again, the smaller peak than before is caused by the resonance of the test device (not shown) during acceleration and deceleration. The reduction is caused by the further distribution of this amount of shake-balanced material in the chamber.
Figure 26 shows an exemplary representation of the acceleration of the vehicle tire with two supplemental rotating elements over time in the fourth cycle, each supplemental rotating element containing the amount of balancing substance in the same ratio as in Figure 22 (#4-4).
In Fig. 26, #4-4 indicates a fourth period of testing of the tires having two supplemental rotating elements 2000, 2010, each supplemental rotating element containing the amount of balancing substance 2300, 2310. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases and peaks at approximately 0.045 g. From about t = 30 s to about t = 330 s, the peripheral velocity is maintained to this extent, and the acceleration a is slightly increased from about 0.045 g and then decreased to about 0.03 g. From about t = 330 s to about t = 360 s, the peripheral speed is reduced to 0 km/h and the acceleration a is reduced to a peak of about 0.04 g.
Again, the smaller peak than before is caused by the resonance of the test device (not shown) during acceleration and deceleration. The reduction is caused by the further distribution of this amount of shake-balanced material in the chamber.
Figure 27 shows an exemplary representation of the acceleration of the vehicle tire with two supplemental rotating elements over time in the fifth cycle, each supplemental rotating element containing the amount of balancing substance in the same ratio as in Figure 22 (#4-5).
In Fig. 27, #4-5 indicates a fifth cycle of testing with two tires supplementing the rotating elements 2000, 2010, each supplemental rotating element containing this amount of balancing substance 2300, 2310. From t = 0 s to approximately T = 30 s, the peripheral speed increases from 0 km/h to approximately 180 km/h, and the acceleration a increases and peaks at approximately 0.045 g. From about t = 30 s to about t = 330 s, the peripheral velocity is maintained to this extent, and the acceleration a is further reduced from about 0.023 g to a minimum of about 0.01 at about 120 s, and then increased to about 0.03 g. From about t = 330 s to about t = 360 s, the peripheral speed is reduced to 0 km/h and the acceleration a is reduced to a peak of about 0.06 g.
Again, the peak is caused by the resonance of the test device (not shown) during acceleration and deceleration. The reduction is caused by the further distribution of this amount of shake-balanced material in the chamber. At a minimum, this amount of shake-density balancing material has a distribution within the rotating element such that vibration is reduced or minimized. However, the subsequent increase is caused by the seal 2600 being accidentally detached from the rotating element 2000 and the balancing material leaking uncontrollably into the tire 1000.
Furthermore, a comparison of Figures 22 and 27 shows that the balancing system according to an embodiment of the present invention substantially reduces the vibration of a vehicle tire having two complementary rotating elements as compared to a vehicle tire balanced by metal weight. Each supplemental rotating element contains a balance material in an amount from about 0.04 g to about 0.01 g, which is a relative reduction of 75%.

FIG. 28 schematically illustrates the adapter 3000 and the frame edge 3100. The adapter 3000 is for attachment to the bezel 3100. The adapter 3100 includes a ring portion 3150 and an attachment portion 3200. The ring portion 3150 is wheel-shaped and abuts the frame edge 3100. The ring portion 3150 is hollow, forming a chamber. The chamber is unobstructed so that the balancing material can flow freely into the chamber. When used, the chamber contains a balancing substance. The balancing material is preferably the equilibrium gel discussed above. The balancing material is preferably a shake denatured gel as discussed elsewhere in this specification. Not illustrated here, the frame edge 3000 is rotatable about a rotational axis. As mentioned above, the center of rotation and the uncorrected center of gravity will cause the frame edge and the tire combination to oscillate or vibrate because the frame edge and the tire system will then be unbalanced.
The tire for mounting on the rim 3000 may be a pneumatic tire and contain a pressurized gas or gas mixture, such as an atmosphere (not shown). The tire can be intended for use in motorized vehicles such as automobiles, buses, light trucks, heavy trucks or motorcycles, or aircraft.
The attachment portion 3200 includes a portion 3250 for abutting the bezel 3100, with some openings or holes for allowing the embolic or screw to attach the combined adapter 3000 and the bezel 3100 to the vehicle. This combination can be used in connection with automobiles, trucks, trucks, vans or the like as mentioned above.
The adapter 3000 is used to reduce the imbalance in the rim 3100 and the tire combination. As previously discussed, this reduces the wear of not only the tire but also the connecting elements (ie the shaft and possibly the engine), since the vibrations originating from the vibration of the tire and the vibrations are transmitted from the wheel via the shaft, and Further access to the vehicle.
The ring portion 3150 has a circular cross section. The ring portion 3150 has a fixed radius. The amount of equilibrium gel required depends on the size of the frame 3100 and the combination of tires and weight. The amount of equilibrium gel required can be determined using a balance or based on the tire and the type of frame group or characteristics of the tire. In some embodiments, the loop portion 3150 has an opening for adding or removing some or all of the equilibrium gel. In some embodiments, the loop portion 3150 is sealed such that the amount of equilibrium gel is substantially fixed and isolated from the surroundings.
When the adapter and the rim are mounted on the vehicle, the adapter 3000 is placed on the side of the frame that faces away from the vehicle.
Figure 29 illustrates an adapter 3300 mounted on the side of the frame. The adapter 3300 includes a hook 3350 adapted to engage an opening portion of the bezel. The hook 3350 is attached using a screw. The adapter 3300 includes a number of hooks. The number of hooks can be selected based on the size of the adapter 3300. Larger adapters for trucks or trucks may require more hooks than adapters for cars with relatively small bezels.
Figure 30 is an enlarged view of the portion of the adapter 3300 of Figure 29 with hooks 3350 attached to the frame edges.
Figure 31 illustrates an adapter 3400. The adapter 3400 has a full surface contact portion 3410 for establishing intimate contact between the adapter 3400 and the frame edges, not illustrated. The adapter 3400 has a chamber or ring portion 3450 similar to the adapter of Figure 29. When properly attached, some embosses secure the adapter 3400 to the side of the frame that faces away from the vehicle.
The adapter 3400 can be made of steel or high alloy steel and mounted to the side of the steel frame or to the side of the aluminum frame. In some embodiments, the adapter 3400 can be made of plain steel, lacquered or chromed, stainless steel, aluminum or plastic.
In general, the adapters illustrated herein can be attached to the rim using embosses. In some embodiments, however, the adapter can be welded to the rim, which is from steel or aluminum.
The adapter 3500 is illustrated in FIGS. 32 and 33. In Fig. 32, a front view is exemplified. In Fig. 33, an isometric view is illustrated. The adapter 3500 includes a wheeled chamber 3510 similar to that illustrated in FIG.
The adapter 3500 has two openings 3510 disposed proximate the center of the adapter 3500 and two additional openings 3520 disposed at a greater distance from the center. These openings 3510 and 3520 provide cooling of the rims as they allow air to pass through. Moreover, the openings 3510 and 3520 provide rigidity to the adapter 3500 as compared to a fully closed adapter.
Figure 34 illustrates an adapter 3600. The adapter 3600 includes an annular portion 3610. Five attachments 3620 extend from the annular portion 3610 toward the center of the adapter 3600. The attachment is in the form of a label. The attachment 3620 is for attachment to the bezel via a set of rim embossments. The attachment 3620 ensures that the adapter 3600 is securely secured to the vehicle along with the rim. In addition, a relatively large portion of the bezel to which the adapter 3600 is attached will be exposed to airflow that will help cool the bezel and the vehicle's brakes. In Fig. 35, the attachment 3620 is shown joined on one side of the annular portion 3610, curved so that they can contact the bezel and allow the annular portion 3610 to bear the bezel.
Figure 36 illustrates an adapter 3600 mounted on a frame edge 3630.
Figure 37 illustrates an adapter 3700 having ten attachments 3710 and of a type similar to that illustrated in Figures 34-36. The number of attachments in a particular embodiment depends on the type of rim to which the adapter is attached.
Figure 38 illustrates an embolic protection cover integrated with the adapter 3800. The adapter has an annular portion 3810 having a wheeled chamber that is at least partially filled with a balancing substance.
Four embolic attachment portions 3820 extend from surface 3830. When the embossed protective cover is installed, the embossing passes through the opening 3840, extending through the yoke attachment portion 3820 and the rim to attach the embossing cover integrated with the adapter 3800 and the rim to The vehicle.
Figure 40 illustrates the back side of the adapter 3800 integrated with the embossed protective cover. In this field of view, the embolic attachment portion 3820 can be seen to extend from the surface 3830.
Figure 41 illustrates a cross-sectional view of the chamber 3900. The chamber 3900 is partially filled with a balancing substance 3910. An adapter having such a chamber 3900 can be more suitable for some frame geometry. It allows such an adapter to carry a larger surface than the toroidal adapter. The ring adapter, such as the adapter of Figure 39, can accommodate the bulging portion of the rim, but for some rim geometry, this is not possible.
Figures 41 and 42 illustrate an embolic protection cover integrated with an adapter having a geometry such as that illustrated in Figure 40.
In other embodiments, the adapter can have a chamber that does not form a circular or continuous chamber. The chamber can be U-shaped or C-shaped. The chamber is then closed at one end by a lid that is bonded or welded to the upper portion. Thus, the adapter can have a coverage of 100% to 75%, or 90% to 50% or 80% to 45%, or 75% to 25% or 50% to 15 at the center of rotation from which the chamber is located. % of the chamber around the perimeter of the frame. Multiple adapters can be used to cover the perimeter of the frame edge.
The adapters discussed above can be used in a method for reducing vibration in a rotating system. The method can include providing a wheel frame having a perimeter, an adapter member including a chamber having a cross-section and a quantity of balancing material, the wheel frame and the chamber having a rotational axis, the method comprising Attaching the wheel frame and the adapter to a vehicle.
A bezel for the vehicle may be provided, wherein the bezel has a chamber that may be partially filled with a balancing substance that distributes itself during rotation of the bezel. The frame edge can have more than one chamber, each chamber being filled with a balancing substance to some extent. The plurality of chambers do not need to have the same exact amount of balancing material. The balancing material can be a rheologically modified material as discussed above.
Such a frame edge is illustrated in Fig. 44, in which a section of a portion of the frame edge is shown. Here, the hollow space allows a quantity of balancing material to be located within the frame edge, i.e., in the hollow space. This ensures that a quantity of balancing material is present to compensate for the change in the rim and the balance of the tire combination.
