Description

Technical Field

[0001] The invention relates to the field of compressor components, and in particular to a split-type adaptive connecting rod and a compressor. Background Art

[0002] The connecting rod is a key part that connects the crankshaft and the piston in the compressor. The big end and the small end of the connecting rod are connected to the crankshaft and the piston respectively, transmitting the force and motion in the compressor. They are responsible for converting the rotary motion of the crankshaft into the reciprocating motion of the piston to achieve the purpose of compressing gas in the compressor. In the actual installation process of the compressor parts, the connecting rod is required to be perpendicular to the center line of the cylinder seat shaft hole and parallel to the center line of the cylinder seat cylinder hole. However, due to the processing error of the parts, there is an angle deviation between the shaft hole and the cylinder hole of the cylinder seat. This angle deviation causes additional wear during the operation of the compressor parts, increases the power of the compressor, and then reduces the performance of the compressor, affecting the service life of the compressor. The flexible design of the connecting rod can alleviate the additional wear problem caused by the angle deviation of the cylinder seat shaft hole and cylinder hole to a certain extent.

[0003] A Chinese patent (Announcement No. CN202756202U, announcement date 20130227) discloses a split connecting rod for a refrigeration compressor. The U-shaped socket portion on the outside of the connecting rod and the large annular column is equivalent to a cross-shaped universal joint. During the linkage process, once the force on the connecting rod in the vertical direction is unstable, the connecting rod swings slightly in the vertical direction around the connecting rod pin by its plug end to alleviate the uneven vertical force; but its adaptability to the angular deviation of the axis of the hole at both ends of the connecting rod is weak. After the large annular column is coaxially matched with the crank, its axis offset is limited, resulting in it being able to adapt to the offset in a single direction only through the rotation of the connecting rod pin. During the development test or test of the compressor, there is a situation where the axis of the crankshaft matching the connecting rod position and the axis of the piston pin matching the connecting rod position are torsionally offset in multiple directions, resulting in poor parallelism and verticality. The insufficient adaptability of the split connecting rod still leads to abnormal wear of the connecting rod matching the crankshaft position and the connecting rod matching the piston pin position. It is difficult to replace it, which affects the service life of the compressor connecting rod. Summary of the invention

[0004] The purpose of the present invention is to address the defects of the prior art and provide a split adaptive connecting rod and compressor, which adopts a cross joint to connect the crankshaft rod section and the piston rod section to form a split connecting rod, the first shaft rod and the second shaft rod of the cross joint are rotatably connected, and respectively rotatably connect the crankshaft rod section and the piston rod section, so as to form a universal joint at the connection position of the crankshaft rod section and the piston rod section, and set a limit for the rotating pair formed by the first shaft rod parallel to the axis of the hole portion of the rod section. After adapting to the torsional offset, the movement and force transmission requirements between the crankshaft and the piston are met, and the adverse effects of the cross joint position on the transmission process are reduced.

[0005] The first object of the present invention is to provide a split adaptive connecting rod, which adopts the following scheme:

[0006] include:

[0007] A crankshaft rod section, one end of which is provided with a first hole portion matching the crankshaft, and the other end of which is provided with a first groove, first ear plates are respectively provided on both sides of the first groove, and a first shaft hole is opened on the first ear plate, and the axis of the first shaft hole is parallel to the axis of the first hole portion;

[0008] The piston rod section has a second hole portion for matching the piston pin at one end and a second groove at the other end. Second ear plates are respectively provided on both sides of the second groove. A second axial hole is formed on the second ear plate, and the axis of the second axial hole is parallel to the axis of the second hole portion.

[0009] The cross joint includes a first shaft rod and a second shaft rod with vertical axes and rotationally matched. The first shaft rod is rotationally installed in the first shaft hole, and the second shaft rod is rotationally installed in the second shaft hole. The first ear plate is located in the second groove, and the second ear plates on both sides of the first groove constrain the deflection range of the first ear plate.

[0010] Furthermore, the second shaft is provided with a mounting hole which is perpendicular to its axis, and the first shaft is rotatably engaged with the mounting hole.

[0011] Further, the first shaft rod is located between the two second ear plates, and the second shaft rod is located between the two first ear plates.

[0012] Furthermore, the first shaft and the second shaft are rotationally matched via a bearing.

[0013] Furthermore, the end of the first shaft rod passes through the first ear plate, and the first shaft rod outside the first groove is matched with a stop pin, and the end of the second shaft rod passes through the second ear plate, and the second shaft rod outside the second groove is matched with a stop pin.

[0014] Furthermore, along the axial direction of the first shaft, the width of the second ear plate is greater than the sum of the widths of the two first ear plates and the first groove, so that the second ear plate can abut against the deflected first ear plate and restrict the deflection range of the first ear plate.

[0015] Furthermore, a cylindrical structure is provided at one end of the crankshaft rod segment, and a through hole in the center of the cylindrical structure forms a first hole portion.

[0016] Furthermore, a cylindrical structure is provided at one end of the piston rod section, and a through hole in the center of the cylindrical structure forms a second hole portion.

[0017] A second object of the present invention is to provide a compressor with a split adaptive connecting rod, utilizing the split adaptive connecting rod as described in the first object.

[0018] Furthermore, the first hole portion of the split adaptive connecting rod cooperates with the crankshaft of the compressor, and the second hole portion cooperates with the piston pin of the compressor cylinder piston.

[0019] Compared with the prior art, the present invention has the following advantages and positive effects:

[0020] (1) In view of the problem of insufficient adaptability of the current compressor connecting rod, a cross joint is used to connect the crankshaft rod section and the piston rod section to form a split connecting rod. The first shaft rod and the second shaft rod of the cross joint are rotatably connected and respectively rotatably connected to the crankshaft rod section and the piston rod section, thereby forming a universal joint at the connection position of the crankshaft rod section and the piston rod section, and a limit is set for the rotating pair formed by the first shaft rod parallel to the axis of the hole portion of the rod section. After adapting to the torsional offset, the movement and force transmission requirements between the crankshaft and the piston are met, thereby reducing the adverse effects of the cross joint position on the transmission process.

[0021] (2) During actual operation, when torsional offsets in different directions occur between the crankshaft and the piston of the compressor, the rotating fit structure allows the cross joint to effectively adapt to such changes, ensuring that force and motion can be smoothly transmitted between the crankshaft rod section and the piston rod section, avoiding problems such as jamming or abnormal stress caused by the inability to cope with angle changes due to structural limitations, and further enhancing the adaptive ability of the entire connecting rod.

[0022] (3) Configuring ear plates on the crankshaft rod section and the piston rod section respectively helps to accurately guide the relative rotation between the components, so that the first shaft rod can rotate smoothly between the two second ear plates and the second shaft rod can rotate smoothly between the two first ear plates according to the design requirements, thereby preventing the shaft rod from excessively shaking or deviating from the normal rotation trajectory; it also provides a suitable space and relative position basis for other subsequent constraint structures (such as stop pins, etc.) to play a role, thereby synergistically improving the reliability and durability of the entire connecting rod.

[0031] Example 1

[0032] In a typical embodiment of the present invention, Figure 1-Figure 6 As shown, a split adaptive connecting rod is provided.

[0033] During the development and testing of the compressor, the existing split connecting rod has the problem of weak adaptability to the angle deviation of the axis of the hole at both ends of the connecting rod, and the axis of the crankshaft matching the connecting rod position and the axis of the piston pin matching the connecting rod position are torsionally offset in multiple directions. Due to the poor adaptability of the split connecting rod, poor parallelism and verticality will result, which will lead to abnormal wear of the connecting rod matching the crankshaft position and the connecting rod matching the piston pin position, and it is difficult to replace it, which affects the service life of the compressor connecting rod. Based on this, this embodiment provides a split adaptive connecting rod structure, which uses a cross joint 3 to form a universal joint at the connection position of the crankshaft rod section 1 and the piston rod section 2, and sets a corresponding limit structure, which solves the problem that the connecting rod in the prior art is difficult to adapt to multi-directional torsional offset, is easily adversely affected by offset, and the resulting abnormal wear, replacement difficulty and service life.

[0034] like Figure 1 As shown, the split adaptive connecting rod includes a crankshaft rod section 1, a cross joint 3 and a piston rod section 2 which are connected in sequence. One end of the crankshaft rod section 1 is used to cooperate with the crankshaft, and the other end cooperates with one of the shaft rods of the cross joint 3. One end of the piston rod section 2 is used to cooperate with the piston shaft, and the other end cooperates with another shaft rod in the cross joint 3, so that the piston rod section 2 and the rod sections can be flexibly adjusted.

[0035] Specifically, Figure 3As shown, one end of the crankshaft rod segment 1 is provided with a first hole portion for matching the crankshaft, and the first hole portion is used to connect with the crankshaft of the compressor to ensure that the two can achieve effective transmission connection. The other end of the crankshaft rod segment 1 is provided with a first groove, and first ear plates 7 are respectively provided on both sides of the first groove. The two first ear plates 7 are relatively spaced and distributed. A first shaft hole is opened on the first ear plate 7, and the axis of the first shaft hole is parallel to the axis of the first hole portion, providing basic structural conditions for subsequent connection with the cross joint 3 and corresponding rotational cooperation.

[0036] The crankshaft rod segment 1 serves as the starting part of the connection between the entire split adaptive connecting rod and the compressor crankshaft. It carries the power input from the crankshaft and transmits it to the subsequent structure. At the same time, it provides support for the assembly and relative movement with the cross joint 3 through its own structure.

[0037] Combination Figure 1 and Figure 3 A second hole portion that matches the piston pin is provided at one end of the piston rod segment 2, so that it can be connected to the piston pin, and then associated with the piston component of the cylinder, to achieve the transmission of force and motion to the piston. A second groove is provided at the other end of the piston rod segment 2, and correspondingly, second ear plates 8 are provided on both sides of the second groove, respectively. The two second ear plates 8 are arranged relatively spaced apart, and a second axial hole is opened on the second ear plate 8, and the axis of the second axial hole is parallel to the axis of the second hole portion, which is similar to the structure of the crankshaft rod segment 1, and meets the structural requirements of connecting the cross joint 3 and rotating relative to it.

[0038] The piston rod section 2 is a structure that connects the split adaptive connecting rod and the piston part. It receives the power and motion transmitted from the front structure and transmits it to the piston, pushing the piston to perform corresponding reciprocating motion, thereby realizing the suction, compression, exhaust and other working processes of the compressor.

[0039] like Figure 1-Figure 6 As shown, the cross joint 3 is composed of a first shaft rod 5 and a second shaft rod 6 whose axes are perpendicular and mutually rotatable. The first shaft rod 5 is rotatably installed in the first shaft hole of the crankshaft rod segment 1, and the second shaft rod 6 is rotatably installed in the second shaft hole of the piston rod segment 2, forming two rotation pairs in mutually perpendicular directions. At the same time, the first ear plate 7 of the crankshaft rod segment 1 is located in the second groove of the piston rod segment 2, and the second ear plates 8 on both sides of the first groove can constrain the deflection range of the first ear plate 7. The structural layout enables the cross joint 3 to achieve flexible multi-directional rotation while limiting the relative motion range between the components to a certain extent.

[0040] The cross joint 3 serves as the core connection and transmission component of the entire connecting rod, and plays a function similar to a universal joint. It can adapt to the torsional offset in different directions between the crankshaft rod section 1 and the piston rod section 2, ensuring that the movement and force transmission between the crankshaft and the piston can be carried out relatively smoothly during the operation of the compressor, reducing the adverse effects caused by structural incoordination.

[0041] Through the special structure of the cross joint 3 and the connection and cooperation between the various components, the connecting rod can better adapt to the torsional offset of the connection position of the crankshaft rod section 1 and the piston rod section 2. It is no longer limited to the offset adaptation in a single direction. It effectively copes with the multi-directional axis angle changes that may occur in actual operation, and improves the adaptability of the entire connecting rod structure to complex working conditions.

[0042] On the basis of adapting to torsional deviation, the movement and force transmission requirements between the crankshaft and the piston are met, ensuring that the normal working process of the compressor can be carried out stably and smoothly, avoiding problems such as power transmission interruption and unsmoothness caused by insufficient adaptability of the connecting rod structure, and helping to improve the overall working efficiency and reliability of the compressor.

[0043] A limit is set for the revolving pair formed by the first shaft 5 parallel to the axis of the hole portion of the rod segment, which reasonably constrains the relative motion range between the components and reduces the adverse effect of the position of the cross joint 3 on the transmission process. For example, abnormal wear caused by excessive deflection can be avoided, thereby extending the service life of the connecting rod and related components and reducing the maintenance cost of the compressor and the frequency of replacing parts.

[0044] like Figure 4 and Figure 6 As shown, the second shaft rod 6 is provided with a mounting hole which is perpendicular to its axis, and the first shaft rod 5 is rotatably fitted in the mounting hole, thereby constructing a mutually perpendicular and rotatable relationship between the two shaft rods in the cross joint 3, so that the first shaft rod 5 can flexibly rotate around the axis of the mounting hole relative to the second shaft rod 6, laying a precise mechanical structure foundation for realizing the function of the universal joint.

[0045] During actual operation, when torsional offsets in different directions occur between the crankshaft and the piston of the compressor, the rotating matching structure allows the cross joint 3 to effectively adapt to such changes, ensuring that force and motion can be smoothly transmitted between the crankshaft rod section 1 and the piston rod section 2, avoiding problems such as jamming or abnormal stress caused by the inability to cope with angle changes due to structural limitations, and further enhancing the adaptability of the entire connecting rod.

[0046] The first shaft 5 is located between the two second lugs 8, and the second shaft 6 is located between the two first lugs 7, forming a mutually nested and mutually constrained layout, making the coordination between the various components more compact and orderly, and reasonably limiting the shaft and lugs in terms of spatial position, which helps to ensure the stability and integrity of the entire connecting rod structure during movement.

[0047] On the one hand, it helps to accurately guide the relative rotation between the components, so that the first shaft rod 5 can rotate smoothly between the two second ear plates 8 and the second shaft rod 6 can rotate smoothly between the two first ear plates 7 according to the design requirements, preventing the shaft rod from excessively shaking or deviating from the normal rotation trajectory; on the other hand, it also provides a suitable space and relative position basis for other subsequent constraint structures (such as the stop pin 4, etc.) to play a role, thereby synergistically improving the reliability and durability of the entire connecting rod.

[0048] like Figure 5 and Figure 6 As shown, the first shaft rod 5 and the second shaft rod 6 are rotationally matched through bearings. Bearings are used to achieve the rotational match of the first shaft rod 5 and the second shaft rod 6. The bearings can significantly reduce the friction resistance of the two shaft rods during relative rotation, making the rotation more flexible and smooth, and can withstand certain axial and radial loads, thereby improving the load-bearing capacity and service life of the rotating pair.

[0049] During the long-term reciprocating motion of the compressor, the rotation action at the cross joint 3 is frequently involved. The use of bearings can ensure that the rotation between the first shaft 5 and the second shaft 6 always maintains a good state, reducing the energy loss and component wear caused by friction, and ensuring that the entire connecting rod structure can stably adapt to the movement and force transmission requirements between the crankshaft and the piston for a long time, thereby improving the working efficiency and operating stability of the entire compressor.

[0050] The end of the first shaft rod 5 passes through the first ear plate 7, and the first shaft rod 5 outside the first groove is matched with a stop pin 4. The end of the second shaft rod 6 passes through the second ear plate 8, and the second shaft rod 6 outside the second groove is matched with a stop pin 4. Specifically, after the end of the shaft rod passes through the ear plate, a stop pin 4 is set on the corresponding shaft rod outside the groove, adding a limit structure to the axial movement of the shaft rod. The stop pin 4 can prevent the shaft rod from axial movement due to various forces (such as inertia force, impact force, etc.) during the rotation process, so that the shaft rod always rotates within the position range required by the design.

[0051] From the perspective of the operation of the entire connecting rod, the stop pin 4 enhances the stability of the structure and avoids the disorder of the assembly relationship between the components caused by the axial movement of the shaft, thereby ensuring the normal function of the cross joint 3 and the accuracy of the movement and force transmission between the crankshaft rod section 1 and the piston rod section 2, reducing abnormal wear and transmission failure caused by abnormal displacement of the shaft, and extending the service life of the connecting rod.

[0052] In the axial direction of the first shaft 5, the width of the second ear plate 8 is greater than the sum of the widths of the two first ear plates 7 and the first groove, so that the second ear plate 8 can abut against the first ear plate 7 after deflection and restrict the deflection range of the first ear plate 7. The larger width of the second ear plate 8 is utilized to provide the physical conditions for restricting the deflection range of the first ear plate 7. Through reasonable spatial layout, when the first ear plate 7 deflects due to various reasons, the second ear plate 8 can abut against it in time and restrict its further deflection, forming a mechanical limit mechanism.

[0053] During the operation of the compressor, although the cross joint 3 must have a certain degree of adaptive ability to cope with torsional offset, it is also necessary to properly control the relative motion range of each component to prevent excessive deflection from causing structural damage or transmission abnormality. In this embodiment, this control function is achieved by using the mutual constraint between the ear plates, ensuring that the cross joint 3 works within the allowable angle variation range, optimizing the adaptability of the entire connecting rod structure to multi-directional torsional offset, and also helping to maintain good matching accuracy between the components and reduce problems such as abnormal wear caused by excessive deflection.

[0054] One end of the crankshaft rod section 1 is provided with a cylindrical structure, and the through hole in the center of the cylindrical structure forms a first hole portion, and one end of the piston rod section 2 is provided with a cylindrical structure, and the through hole in the center of the cylindrical structure forms a second hole portion. In this embodiment, the cylindrical structure can provide a better containment and positioning effect for the connecting parts (such as the crankshaft and the piston pin), making it easier to achieve the precision requirements such as coaxiality during the assembly process, and it is also conducive to the uniform transmission of force during the subsequent operation process.

[0055] In the actual assembly and operation of the compressor, the hole can ensure the reliability and stability of the connection between the connecting rod and the crankshaft and piston pin, ensure that the force can be accurately transmitted along the designed path, reduce problems such as uneven force and looseness caused by unreasonable connection parts structure, maintain the normal working order of the entire compressor and extend the service life of related parts. The split adaptive connecting rod effectively solves many problems existing in the existing technology through the coordinated cooperation of various parts of the structure, and has achieved remarkable technical effects.

[0056] Example 2

[0057] In another typical embodiment of the present invention, Figure 1-Figure 6 As shown, a compressor with a split adaptive connecting rod is provided, which utilizes the split adaptive connecting rod as in Example 1.

[0058] The split adaptive connecting rod is composed of a crankshaft rod section 1, a piston rod section 2 and a cross joint 3. The crankshaft rod section 1 is provided with a first hole portion matching the compressor crankshaft at one end, and a first groove and a corresponding first ear plate 7 and a first shaft hole and other structures at the other end; the piston rod section 2 is provided with a second hole portion matching the piston pin shaft of the compressor cylinder piston at one end, and a second groove and a matching second ear plate 8 and a second shaft hole and other structures at the other end; the cross joint 3 is respectively rotatably matched with the shaft holes of the crankshaft rod section 1 and the piston rod section 2 through its first shaft rod 5 and second shaft rod 6, and has a series of fine structural designs such as rotational matching between shaft rods through bearings, setting of stop pins 4 to limit the axial movement of the shaft rod, and using the width of the ear plate to constrain the swing range, so as to achieve a function similar to a universal joint and adapt to multi-directional torsional offset conditions.

[0059] In the compressor, the split adaptive connecting rod connects the compressor crankshaft and the cylinder piston, transmitting the crankshaft's rotational motion and power to the piston. Through its own adaptive structural characteristics, it ensures that when complex working conditions such as various torsional offsets occur between the crankshaft and the piston, the motion and force can still be transmitted stably and smoothly, thereby ensuring the normal operation of the compressor.

[0060] It can be understood that the compressor crankshaft is the power input component of the compressor, which transmits the rotational power from the external power source (such as a motor, etc.) to the split adaptive connecting rod. It has certain strength and rigidity requirements to drive the connecting rod to drive the piston to reciprocate and realize gas compression and other working processes.

[0061] The compressor cylinder piston is located inside the compressor cylinder and can do reciprocating motion in the cylinder. By changing the volume in the cylinder, it can realize operations such as gas suction, compression and discharge. The piston pin is used to connect the piston and the piston rod section 2 of the split adaptive connecting rod, so that the movement of the connecting rod can be accurately transmitted to the piston, driving the piston to perform corresponding actions, and it must be able to withstand various forces generated during the movement to ensure the reliability of the connection.

[0062] In this embodiment, the compressor adopts the one-piece adaptive connecting rod as in Embodiment 1, and utilizes the characteristics of the connecting rod that can adapt to multi-directional torsional deviation, effectively solving a series of problems caused by the poor adaptation of the connecting rod to the axis angle deviation, including abnormal wear at the fitting, reduced component life, compressor failure, and high maintenance costs, thereby ensuring the stable and reliable operation of the compressor under complex working conditions. The compressor can better cope with the complex stress and torsional deviation caused by various internal and external factors (such as different installation environments, changes in working conditions, etc.) during actual operation, broadening the range of conditions under which the compressor can work stably, improving the compressor's adaptability to different application scenarios, and helping it to be reliably applied in more fields.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
