TECHNICAL FIELD
[0001] The present application relates to the technical field of compressors, in particular to an oil-blocking balance piece and a compressor. BACKGROUND
[0002] The compressor is internally provided with a balance block and an oil-blocking plate. The balance block is used to reduce the radial force generated during the operation of the motor, and the eccentric rotation of the rotating shaft is balanced by adjusting the weight distribution, so as to reduce the vibration and noise. The oil-blocking plate is mainly used to protect the internal components from oil splashing, and to keep the flow of lubricating oil stable.
[0003] In the prior art, the core-pulling rivet type balance block has been gradually replaced by an integrated balance block due to the problem of oil-blocking plate falling off. The manganese steel reverse buckle integrated balance block has problems such as concentricity difference during the assembly of the rotor due to its large mass and high cost. On some small machine types, the balance block is combined with the oil-blocking plate to form an integrated style. In order to better achieve the oil-blocking effect, the height of the lifting part of the oil-blocking plate is generally required to be close to the height of the balance block. However, on large machine types, if the height of the balance block is too high, the lifting part of the oil-blocking plate cannot be stacked high, and cannot be matched with the balance block. The universality of the existing balance block and oil-blocking plate is low, which increases the cost of the compressor. SUMMARY

[0008] In some embodiments, the first protruding block is matched with the notch, the oil-blocking plate body abuts against the upper surface of the second protruding block, and the balance block and the oil-blocking plate body jointly form a circumferential structure.
[0009] In some embodiments, the oil baffle further includes a lifting portion disposed on the side of the oil baffle body near the annular plate; the oil baffle body is provided with a central through hole, and the lifting portion is arranged around the central through hole.
[0010] In some embodiments, the protrusion height of the second protrusion is H1, the height of the annular plate is H2, and the height of the lifting part is H3, satisfying: 0.1mm≤H1+H2-H3≤1mm.
[0011] In some embodiments, the height of the lifting section satisfies: 3.9mm≤H3≤5.9mm.

[0043] To address the problems in the prior art, this invention provides an oil baffle balance component, including an oil baffle plate and a balance block. The oil baffle plate includes an oil baffle plate body, a notch on the outer edge of the oil baffle plate body, and at least one first mounting hole in the circumferential direction of the oil baffle plate body.
[0044] The balance block includes an annular plate, a first protrusion, and a second protrusion. The second protrusion protrudes from the surface of the annular plate near the oil baffle plate, and the first protrusion protrudes from the surface of the second protrusion facing the oil baffle plate. In the axial direction of the oil baffle balance component, the projected area of the first protrusion is smaller than the projected area of the second protrusion, and the second protrusion has at least one second mounting hole.
[0045] When the fastener is placed in the first mounting hole and the second mounting hole, the oil baffle is fixedly connected to the balance block, and the first protrusion is placed in the notch.
[0046] In this technical solution, the assembly of the balance block and the oil baffle is simple, which improves the assembly efficiency of the oil baffle balance component. When the balance block and the oil baffle are assembled together, the first protrusion of the balance block is located in the notch. The notch on the oil baffle can accommodate a variety of first protrusions with different protrusion heights. That is, the oil baffle can be adapted to a variety of balance blocks, with high versatility and wide applicability. It does not require a certain type of balance block to match a certain type of oil baffle. The mold opening requirements for the oil baffle are small, which can reduce the production cost of the oil baffle and reduce the production cost of the oil baffle balance component.
[0047] The oil-blocking balance component provided by the present invention will be explained in detail below with reference to specific embodiments.
[0048] like Figures 1 to 4 As shown, the oil baffle balance component provided in the embodiment of the present invention includes an oil baffle plate 100 and a balance block 200. The oil baffle plate 100 includes an oil baffle plate body 110. A notch 111 is provided on the outer edge of the oil baffle plate body 110. At least one first mounting hole 112 is provided in the circumferential direction of the oil baffle plate body 110.
[0049] The balance block 200 includes an annular plate 210, a first protrusion 220 and a second protrusion 230. The second protrusion 230 protrudes from the surface of the annular plate 210 near the oil baffle 100, and the first protrusion 220 protrudes from the surface of the second protrusion 230 facing the oil baffle 100. In the axial direction of the oil baffle balance component, the projected area of the first protrusion 220 is smaller than the projected area of the second protrusion 230. The second protrusion 230 has at least one second mounting hole 231.
[0050] When the fastener is placed in the first mounting hole 112 and the second mounting hole 231, the oil baffle 100 is fixedly connected to the balance block 200, and the first protrusion 220 is placed in the notch 111.
[0051] The oil baffle 100 and balance block 200 are simple to assemble, which can improve the efficiency of assembly. The notch 111 on the oil baffle 100 can accommodate a variety of first protrusions 220 with different protrusion heights. That is, the oil baffle 100 can be adapted to a variety of models of balance blocks 200. It has high versatility and wide applicability. It does not require a certain model of balance block to match a certain type of oil baffle 100. The mold opening requirements of the oil baffle 100 are small, which can reduce the production cost of the oil baffle 100 and the production cost of the oil baffle balance component.
[0052] Furthermore, such as Figures 1 to 4As shown, in this embodiment, the first protrusion 220 of the balance block 200 is adapted to the notch 111. When the oil baffle 100 and the balance block 200 are assembled as a whole, the oil baffle body 110 abuts against the upper surface of the second protrusion 230, and the balance block 200 and the oil baffle body 110 together form a circumferential structure. Setting the balance block 200 and the oil baffle body 110 to form a circumferential structure facilitates the processing of the shape of the first protrusion 220 and the shape of the notch 111 of the balance block 200.
[0053] For further information, please continue to refer to [link / reference]. Figures 1 to 4 The oil baffle 100 also includes a lifting part 120, which is located on the side of the oil baffle body 110 near the annular plate 210; the oil baffle body 110 is provided with a central through hole 113, and the lifting part 120 is arranged around the central through hole 113.
[0054] Furthermore, such as Figure 3 As shown, the protrusion height of the second protrusion 230 is H1, the height of the annular plate 210 is H2, and the height of the lifting part 120 is H3, satisfying the condition: 0.1mm≤H1+H2-H3≤1mm. By reasonably setting the heights of the second protrusion 230, the annular plate 210, and the lifting part 120, the oil baffle balance component is well assembled and has high reliability.
[0055] Furthermore, the height H3 of the lifting section 120 satisfies: 3.9mm≤H3≤5.9mm.
[0056] For further information, please refer to [link / reference]. Figures 1 to 4 The balance block 200 also includes a support column 240, which protrudes from the surface of the annular plate 210 near the oil baffle 100. The height of the support column 240 is equal to the height of the second protrusion 230, and the support column 240 is provided with a second mounting hole 231. The support column 240 is provided to provide more mounting positions when assembling the oil baffle 100 and the balance block 200, thereby improving the connection stability between the two.
[0057] Furthermore, such as Figures 1 to 4As shown, the oil baffle body 110 has a plurality of evenly arranged first mounting holes 112 on its circumference, and the second protrusion 230 has second mounting holes 231 at both ends. The first mounting holes 112 correspond to the second mounting holes 231 of the second protrusion 230 and the second mounting holes 231 of the support column 240. It should be noted that the position of the second mounting holes 231 on the second protrusion 230 is not limited to the ends of the second protrusion 230 as described above. They can also be set in the middle of the second protrusion 230 or other positions, depending on actual needs. When assembling the oil baffle 100 and the balance block 200, firstly, the first mounting holes 112 on the oil baffle 100 are aligned with the second mounting holes 231 on the balance block 200. Then, fasteners are used to pass through the first mounting holes 112 and the second mounting holes 231, thereby fixing the oil baffle body 110 and the balance block 200 together. It should be noted that, due to the presence of the second protrusion 230 and the support column 240, the oil baffle body 110 does not directly contact the annular plate 210, but a certain gap is reserved.
[0058] Furthermore, the fastener in this embodiment is any one of a rivet, bolt, or screw, and can be specifically set according to actual needs.
[0059] This invention also provides a motor rotor, comprising:
[0060] The oil-blocking balance component as described above;
[0061] The rotor core has oil-blocking balance components at both axial ends.
[0062] Since the motor rotor includes the aforementioned oil-blocking balance component, it can achieve all the technical effects of the oil-blocking balance component, which will not be elaborated here.
[0063] This invention also provides a compressor, including a motor, wherein the motor includes a motor rotor as described above. Since the compressor includes the aforementioned motor rotor, all the technical effects of the motor rotor can be achieved, and will not be elaborated further here.
[0064] In summary, the oil-blocking balance component and compressor provided by this invention have the following advantages:
[0065] The assembly of the balance block and the oil baffle is simple, which improves the assembly efficiency of the oil baffle balance component. When the balance block and the oil baffle are assembled together, the first protrusion of the balance block is located in the notch. The notch on the oil baffle can accommodate a variety of first protrusions with different protrusion heights. That is, the oil baffle can be adapted to a variety of balance block models, with high versatility and wide applicability. It is not necessary for one model of balance block to match one type of oil baffle. The mold opening requirements for the oil baffle are small, which can reduce the production cost of the oil baffle and the production cost of the oil baffle balance component.
[0066] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
