Description

Technical Field

[0001] The present invention relates to the technical field of vibration reduction of rotating machinery, and in particular to a connecting rod, a connecting rod assembly, a vibration reduction assembly, a rotating machinery, a compressor, a refrigerator and an air conditioner. Background Art

[0002] Rotating machinery often generates vibration and noise due to swing and / or circumferential rotation vibration during operation due to rotation. Therefore, how to avoid vibration and noise caused by swing and / or circumferential rotation is a technical problem that people have been seeking to solve.

[0003] This technical problem is more common in the field of compressors. For example, the rotary compressor currently used in household air-conditioning systems uses a motor to drive the cam to rotate and compress and inhale the refrigerant. Due to the imbalance of the rotary compressor itself and the periodicity of the internal forces with the rotation angle during operation, its overall structure is accompanied by severe vibration during operation, which not only causes noise problems, but also causes potential stress damage to the external unit pipeline. Therefore, vibration reduction of compression has become an urgent problem to be solved in the field of household air-conditioning. In existing household air conditioners, the main means of reducing vibration of compressors is to set compressor feet at the bottom of the compressor near the bottom shell of the external unit and install foot pads on the compressor feet. The main foot pads are rubber foot pads, spring rubber foot pads, etc., and the vibration reduction characteristics of the rubber foot pads are controlled by changing the outer contour of the rubber foot pads, so as to reduce vibration for different compressors. However, currently the foot pads are all installed at the bottom of the compressor and can only constrain the bottom of the compressor. The compressor is generally a long cylinder (the height is greater than the diameter), which is prone to swinging and rotational vibration during operation. The intake and exhaust ports are both set at the top of the compressor. Therefore, it generally affects the piping of the air conditioner outdoor unit, and the reliability optimization and verification of the outdoor unit pipeline need to be repeatedly performed. Summary of the invention

The rod body 3 is inclined relative to the flat part 2, and the angle between the two is greater than 90 degrees, so the extension range of the peripheral side of the rotating machine body 4 is relatively large, and the constraint range of the peripheral side of the rotating machine body 4 is large, thereby achieving a better constraint effect on the rotating machine body 4.

[0090] Preferably, the upper fixed end has a diameter-changing structure (6, 7, 8), which has the same function as that in the first embodiment.

[0091] Preferably, the flat portion 2 is provided with a through hole 14 for cooperating with a positioning bolt of the rotating machine body 4 to be connected to the base 13 of the rotating machine, which has the same function as that of the first embodiment.

[0092] Embodiment 3

[0093] The present invention provides an embodiment of a connecting rod assembly for a rotating machine, wherein the rotating machine includes a rotating machine body 4 and a base 13 supported below the rotating machine body 4 , and the connecting rod assembly is connected between the rotating machine body 4 and the base 13 to position and reduce vibration of the rotating machine body 4 .

[0094] See also Figure 5 Specifically, the connecting rod assembly embodiment includes four connecting rods, each of which is formed with a rod body 3;

[0095] The upper ends of the rod bodies 3 of the four connecting rods are connected together in pairs to form two upper fixed ends;

[0096] The lower ends of the rod bodies 3 of the four connecting rods form three lower fixed ends, wherein the lower ends of the rod bodies of two connecting rods each form a fixed end independently, and the lower ends of the rod bodies of two adjacent connecting rods are connected together to form a lower fixed end, and the rod bodies of the two connecting rods connected at the lower ends correspond to different upper fixed ends;

[0097] The two rod bodies 3 corresponding to each upper fixed end are forked downward from the upper fixed end; the two rod bodies 3 corresponding to each lower fixed end are forked upward from the lower fixed end;

[0098] The upper fixed end is used to cooperate with the rotating mechanical body 4, and the lower fixed end is used to cooperate with the base 13;

[0099] Each of the lower fixed ends is formed with a flat portion 2 for mating and connecting with the base 13;

[0100] The rod body 3 of each connecting rod is arranged obliquely relative to the flat portion 2, and the angle between the two is greater than 90 degrees.

[0101] Here, "forked" means that the non-fixed ends of the two rod bodies are arranged at a certain angle relative to the connecting ends.

[0102] Embodiment 4

[0103] See also Figure 2 The present invention provides a vibration reduction assembly for a rotating machine, the rotating machine comprising a rotating machine body 4 and a base 13 supported below the rotating machine body 4, the vibration reduction assembly is used to be connected between the rotating machine body 4 and the base 13 to position and reduce vibration of the rotating machine body 4, the vibration reduction assembly comprises a connecting rod and an upper connecting portion 1 and a lower connecting portion relatively arranged at the upper and lower ends of the connecting rod; wherein the upper connecting portion 1 is used to connect the connecting rod with the rotating machine body 4, and the lower connecting portion is used to connect the connecting rod with the base 13;

[0104] When the vibration reduction assembly is connected between the rotating machine body 4 and the base 13 for use, the connecting rod is arranged to be inclined relative to the axis of the rotating machine body 4 .

[0105] In this embodiment, the connecting rod plays a rigid connecting role for the upper connecting part 1 and the lower connecting part. Through the coordinated use of the upper connecting part 1, the connecting rod and the lower connecting part, a multi-dimensional effective constraint can be formed on the upper part of the rotating machinery body 4 including the top, the surrounding side and the lower part, and the swing and circumferential rotation vibration of the rotating machinery body 4 during operation can be effectively suppressed and attenuated, thereby reducing the impact on the external machine pipeline, effectively avoiding excessive pipeline strain during operation and start-up and shutdown, and noise problems caused by vibration of the rotating machinery and pipeline.

[0106] Among them, the upper connecting part 1 is fixed to the outer periphery of the upper end cylinder body of the rotating machinery body 4, the lower connecting part is equivalent to the flat part 2 in Example 1, and is fixed with the positioning bolts in the rotating machinery body 4 through the through hole. The upper and lower ends of the rod body 3 are fixedly connected to the upper connecting part 1 and the lower connecting part respectively. The rod body 3 can effectively resist and attenuate the swing and circumferential rotation vibration of the rotating machinery body 4 during the operation, start-up and shutdown, and transportation of the rotating machinery body 4, greatly improving the stress and noise problems of the pipeline.

[0107] The rod body 3 is tilted relative to the axis of the rotating mechanical body 4. The positions of the upper connecting part 1 and the lower connecting part determine the horizontal projection of the rod body 3 on the cross section of the rotating mechanical body 4. The height of the rotating mechanical body 4 and the upper end position of the rod body 3 determine the projection of the rod body 3 on the longitudinal cross section of the rotating mechanical body 4. The above positional relationships jointly determine the tilt angle of the rod body 3 relative to the axis of the rotating mechanical body 4. The tilted setting of the rod body 3 can effectively improve the ability of the rotating mechanical body 4 to resist circumferential rotation.

[0108] Among them, "swing" refers to: upward rotation around the plane passing through the axis of the rotating mechanical body 4; "circumferential rotation" refers to: rotation around the axis of the rotating mechanical body 4.

[0109] With regard to the relationship between the above-mentioned connecting parts and the lower connecting parts, preferably, n upper connecting parts 1 are provided, m lower connecting parts are provided, and F connecting rods are provided;

[0110] At least two of the F connecting rods are connected at their upper ends, and at least two are connected at their lower ends so that the F connecting rods form n upper connecting ends and m lower connecting ends;

[0111] The n upper connection ends are connected to the n upper connection parts 1 in a one-to-one correspondence; the m lower connection ends are connected to the m lower connection parts in a one-to-one correspondence, n≥2, m≥n+1≥3, F≥n+2, F≥m+1;

[0112] Each connecting rod is inclined relative to the axis of the rotating machine body 4, and the projection of each upper connecting end and upper connecting part 1 in the axis direction of the rotating machine body 4 is located between the projections of the lower connecting ends and lower connecting parts of the two connecting rods connected thereto.

[0113] As a specific example, Figure 2 As shown in the embodiment, when the number of n, m, and F is set, the upper connecting parts 1 are provided with two (n=2), the lower connecting parts are provided with three (m=3), the connecting rods are provided with four (F=4), the upper connecting ends are provided with two, and the lower connecting ends are provided with three;

[0114] The two upper connecting parts include a first upper connecting part and a second upper connecting part;

[0115] The three lower connecting parts include a first lower connecting part, a second lower connecting part, and a third lower connecting part;

[0116] The two upper connecting ends include a first upper connecting end and a second upper connecting end;

[0117] The three lower connecting ends include a first lower connecting end, a second lower connecting end, and a third lower connecting end;

[0118] The four connecting rods include a first rod body 301, a second rod body 302, a third rod body 303 and a fourth rod body 304 which are arranged in sequence;

[0119] in

[0120] The upper ends of the first rod body 301 and the second rod body 302 are connected to form a first upper connecting end, which is connected to the first upper connecting portion. The upper ends of the third rod body 303 and the fourth rod body 304 are connected to form a second upper connecting end, which is connected to the second upper connecting portion. The lower ends of the second rod body 302 and the third rod body 303 are connected together to form a second lower connecting end connected to the second connecting portion. The lower connecting end of the first rod body 301 is the first lower connecting end connected to the second lower connecting portion, and the lower connecting end of the fourth rod body 304 is the third lower connecting end connected to the third lower connecting portion.

[0121] Among them, the four connecting rods form a continuous isosceles triangle arrangement, and the two upper connecting ends are located on the concentric circles of the circles where the four lower connecting ends are located; this arrangement is more suitable for matching with existing rotating machinery, such as compressors. Existing compressors are generally long cylinders (the height is greater than the diameter), and the three lower connecting parts are respectively connected to the three base feet on the rotating machinery base 13, and the two upper connecting parts 1 are connected to the outer wall of the long cylinder. The upper and lower ends of the four rod bodies 3 are connected to the upper connecting part 1 and the lower connecting part in a manner of adjacent rods, and surround the outside of the long cylinder, thereby forming a multi-dimensional effective constraint on the upper part of the compressor including the top, the circumference and the bottom. The compressor is very prone to swing and rotational vibration during operation, and the intake and exhaust ports are both set at the top of the compressor, resulting in more severe vibration at the top, and will affect the air-conditioning outdoor unit piping. The vibration reduction component as a whole can effectively suppress and attenuate the swing and circumferential rotational vibration of the compressor during operation, thereby reducing the impact on the external unit pipeline, effectively avoiding excessive pipeline strain during operation and start-up and shutdown, and noise problems caused by rotating machinery and pipeline vibration.

The main connecting frame 101, the first foot pad 102, and the second foot pad 103 are all connected to the upper connecting end of the rod body 3. A partition 1011 is arranged inside the main connecting frame 101. The partition 1011 separates an upper slot 1012 and a lower slot 1013 in the main connecting frame 101. The first foot pad 102 and the second foot pad 103 are respectively connected to the upper slot 1012 and the lower slot 1013, and the first foot pad 102, the second foot pad 103 and the partition are all provided with a positioning through hole 5. The upper connecting end of the rod body 3 is sequentially penetrated by the second foot pad 103, the positioning through hole 5, and the first foot pad 102 from the lower slot 1013, and extends out from the upper slot 1012.

[0124] The outer wall of the main connecting frame 101 and the upper part of the outer wall of the rotating machine body 4 can be connected by a fixed connection method of welding. The arrangement of the first foot pad 102 and the second foot pad 103 makes the connection between the upper connecting part 1 as a whole and the rotating machine body 4 and the connecting rod more tight, thereby more effectively restraining the top of the rotating machine body 4, and effectively suppressing and attenuating the swing and circumferential rotation vibration of the rotating machine body 4 during operation, thereby reducing the impact on the external machine pipeline, effectively avoiding excessive pipeline strain during operation and start-up and shutdown, and noise problems caused by vibration of the compressor and pipeline.

[0125] The arrangement of the upper slot 1012 and the lower slot 1013 can better support the first foot pad 102 and the second foot pad 103, making it more convenient and firm to position the first foot pad 102 and the second foot pad 103 on the upper and lower sides of the main connection frame 101.

[0126] For further information, see Figure 7 The first foot pad 102 includes a first connecting block 1021 and a column 1022 located on the first connecting block 1021. The second foot pad 103 is a block structure. The first connecting block 1021, the column 1022, the partition 1011 and the second foot pad 103 are all provided with positioning holes 5. The upper connecting end of the rod body 3 is composed of a positioning boss 6, a middle positioning section 7 and an upper positioning section 8. The positioning boss 6 and the upper positioning section 8 are respectively provided with a first locking nut 901 and a second locking nut 902. The first locking nut 901 and the second locking nut 902 limit the first foot pad 102, the main connecting frame 101 and the second foot pad 103 in sequence along the vertical direction on the middle positioning section 7.

[0127] The column base 1022 is a hollow cone. The column base 1022 serves as the upper end part of the upper connecting part 1, and the second foot pad 103 serves as the lower end part of the upper connecting part 1. The upper connecting part 1 is fixed as a whole on the connecting rod by the first locking nut 901 and the second locking nut 902. This fixing method can effectively avoid the situation where the first foot pad 102 and the second foot pad 103 are not properly installed, such as being too loose or too tight.

[0128] For further information, see Figure 2 The side wall of the main connection frame 101 connected to the upper part of the rotating machine body 4 is an arc-shaped wall. The setting of the arc-shaped wall allows a larger connection area between the main connection frame 101 and the rotating machine body 4, thereby ensuring that the connection between the main connection frame 101 and the rotating machine body 4 is more secure.

[0129] In summary, regarding the upper connecting part, the arrangement of the first foot pad 102 and the second foot pad 103 makes the connection between the upper connecting part 1 as a whole and the rotating mechanical body 4 and the connecting rod more secure, thereby more effectively constraining the top of the rotating mechanical body 4. The upper connecting part 1 is fixed to the connecting rod as a whole by the first locking nut 901 and the second locking nut 902. This fixing method can effectively avoid the situation where the first foot pad 102 and the second foot pad 103 are not properly installed.

[0130]

Lower connection

[0131] like Figure 1-5As shown, in this embodiment, each of the lower connecting portion embodiments includes a flat portion 2 extending laterally from the connecting rod, and the connecting rod is inclined relative to the flat portion 2, and the angle between the two is greater than 90 degrees. The flat portion 2 in embodiments 1 and 2 and their arrangement and effects are the same as those in this embodiment.

[0132] The flat part 2 is formed integrally with the corresponding connecting rod. The connecting rod and the flat part 2 are integrally formed, which is not only firmly connected but also easy to process.

[0133] See also Figure 1 , 11 , 12, the flat part 2 is provided with a through hole, and the lower connecting part further includes a positioning bolt 11 and a third foot pad 10, and the positioning bolt 11 is fixedly connected with the base 13 of the rotating machine by penetrating the through hole and the third foot pad 10. The flat part 2 can be more conveniently placed on the base foot and the third foot pad 10 provided by the rotating machine body 4, and the flat part 2 is fixedly connected with the base foot and the third foot pad 10 provided by the rotating machine body 4 through the through hole by the positioning bolt 11 on the rotating machine body 4, and there is no need to drill a new hole on the base 13 of the rotating machine body 4, so as to avoid damaging the rigidity of the base 13.

[0134] Embodiment 5 (providing another method for setting the number of upper connecting parts, lower connecting parts and connecting rods)

[0135] Different from the fourth embodiment, this embodiment provides another design idea for the upper connecting part and the lower connecting part for the fourth embodiment, such as the upper connecting part 1, the lower connecting part and the connecting rod are each provided with n; each rod body 3 forms a lower connecting end and an upper connecting end, each upper connecting end is connected to a corresponding upper connecting part, and each lower connecting end is connected to a corresponding lower connecting part, and n≥1.

[0136] Specifically, Fig.11 In the example, the number of n is 1, that is, n=1. The number of upper connecting part 1, lower connecting part and connecting rod is 1, which makes the overall structure of the vibration reduction assembly simpler and more compact, and is suitable for use on rotating machinery with lower power. A single lower connecting part is connected to a foot on the rotating machinery base 13, a single upper connecting part 1 is connected to the upper part of the outer wall of the rotating machinery, and the upper end and lower end of a single connecting rod are connected to the upper connecting part 1 and the lower connecting part, forming a multi-dimensional effective constraint on the top, circumference and bottom of the rotating machinery, effectively suppressing and attenuating the swing and circumferential rotation vibration during the operation of the rotating machinery. It can be understood by those skilled in the art that when the number of n is greater than 1, a plurality of unit groups composed of a single upper connecting part 1, a lower connecting part and a connecting rod can be arranged along the circumference of the rotating machinery, so as to achieve the vibration reduction effect on the rotating machinery.

[0137] Embodiment 6

[0139] by Figure 1 The application shown is a compressor with a connecting rod as shown in Example 1 and Fig.11 The compressor shown in the application of the connecting rod shown in the embodiment 3 is taken as an example. The compressor includes a compressor body 4 and a base 13. The compressor body 4 is provided with a vibration reduction assembly.

[0141] See also Figure 1 , 11 In the present compressor, by setting the vibration reduction assembly, the upper part of the compressor body 4 including the top, the lower part and the peripheral side can be effectively constrained in multiple dimensions, and the swing and circumferential rotation vibration of the compressor body 4 during operation can be effectively suppressed and attenuated, thereby reducing the impact on the external machine pipeline, effectively avoiding excessive pipeline strain during operation and start-up and shutdown, and noise problems caused by vibration of the compressor and pipeline.

Fig.13 , 14 In the monitoring points of the intake bend 1 and the exhaust bend 1, the maximum strain response of the vibration reduction component embodiment of the present application is reduced by 41.7% and 49.5% respectively compared with the control example.
