Description

Technical Field

[0001] This invention belongs to the field of horizontal compressor technology, specifically relating to an oil baffle assembly for a horizontal compressor and a horizontal compressor. Background Technology

[0002] Horizontal compressors, with their advantages of horizontal placement, compact structure, and small height footprint, can be used in cold storage, container refrigeration units, and automotive refrigeration units. Unlike vertical compressors, which utilize the centrifugal force of crankshaft rotation to pump oil, the oil pumping method of horizontal compressors is limited by their horizontal layout and typically relies on the principle of pressure differential to achieve the circulation and supply of lubricating oil.

[0003] Therefore, how to achieve effective oil pumping by reasonably controlling the pressure difference has become a core technical challenge affecting the long-term reliable operation of horizontal compressors. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the present invention provides an oil baffle assembly for a horizontal compressor and a horizontal compressor. By cooperating with the crankshaft, the oil baffle plate can isolate the oil outlet channels on the crankshaft from the motor cavity, thereby reducing the pressure at each oil outlet channel on the crankshaft and facilitating effective oil pumping.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0007] The crankshaft is provided with a crankshaft oil passage. One end of the crankshaft oil passage passes through the end face of one end of the crankshaft. The other end of the crankshaft oil passage is a blocked oil passage end. The blocked oil passage end is adjacent to the end face of the other end of the crankshaft. The other end of the crankshaft is the crankshaft blocked end. The crankshaft blocked end extends out of the shaft hole of the motor rotor. The end face of one end of the motor rotor is the first end face of the motor rotor. The first end face of the motor rotor is adjacent to the crankshaft blocked end.

[0008] The oil baffle assembly includes an oil baffle plate, which is disposed on one side of the first end face of the motor rotor and spaced a certain distance from the first end face of the motor rotor. The oil baffle plate is fixedly connected to the motor rotor. The side of the oil baffle plate facing the first end face of the motor rotor is the inner side of the oil baffle plate. Multiple oil outlet channels communicating with crankshaft oil channels are opened on the crankshaft at a position between the inner side of the oil baffle plate and the first end face of the motor rotor. The oil baffle plate is used to isolate each oil outlet channel from the motor cavity.

[0009] Furthermore, a counterweight is provided between the oil baffle and the motor rotor, and the oil baffle, the counterweight, and the motor rotor are fixedly connected by fasteners.

[0010] Furthermore, the oil baffle plate has a circular crankshaft through hole at a position corresponding to the crankshaft sealing end. The diameter of the crankshaft through hole is adapted to the outer diameter of the crankshaft. The crankshaft sealing end passes through the crankshaft through hole and the crankshaft and oil baffle plate are interference fit.

[0011] Furthermore, the side of the oil baffle plate opposite to the inner side of the oil baffle plate is the outer side of the oil baffle plate, and the end face where the oil passage blocking end is located is on the same plane as the outer side of the oil baffle plate.

[0012] Furthermore, the crankshaft sealing end is opposite to the inner side of the oil baffle and does not penetrate the oil baffle.

[0013] Furthermore, the distance between the inner side of the oil baffle and the first end face of the motor rotor along the crankshaft axis is expressed in Hz, and the axial distance between the oil passage blocking end and the crankshaft blocking end is controlled to be 0.1Hz-0.3Hz.

[0014] Furthermore, the multiple oil outlet channels are distributed at circumferential intervals along the crankshaft.

[0015] Furthermore, the circumferential spacing between any two adjacent oil outlet channels is equal along the crankshaft.

[0016] Furthermore, the diameter of the crankshaft oil channel is denoted as Dn, the oil outlet channel is a rectangular oil outlet groove and / or an oil outlet hole, the width of the rectangular oil outlet groove along the crankshaft axis is controlled to be 0.1Dn-0.3Dn, and the diameter of the oil outlet hole is controlled to be 0.1Dn-0.3Dn.

[0017] A horizontal compressor includes the oil baffle assembly for a horizontal compressor described above.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The oil baffle assembly for a horizontal compressor in this invention includes a crankshaft oil passage within the crankshaft. One end of the crankshaft oil passage penetrates the end face of one end of the crankshaft, and the other end of the crankshaft oil passage is a blocked oil passage end, which is adjacent to the end face of the other end of the crankshaft. The other end of the crankshaft is the blocked crankshaft end, which extends out of the shaft hole of the motor rotor. The end face of one end of the motor rotor is the first end face of the motor rotor, which is adjacent to the blocked crankshaft end. The oil baffle assembly includes an oil baffle plate, which is spaced a certain distance from the first end face of the motor rotor and fixed thereon. The side of the oil baffle plate facing the first end face of the motor rotor is the inner side of the oil baffle plate. Multiple oil outlet channels communicating with the crankshaft oil passage are provided on the crankshaft between the inner side of the oil baffle plate and the first end face of the motor rotor. The oil baffle plate is used to isolate each oil outlet channel from the motor cavity. This invention, through the cooperation of an oil baffle plate and a crankshaft, can isolate the oil outlet channels on the crankshaft from the motor cavity, while connecting the oil outlet channels to the crankshaft oil passage. In this way, during the high-speed rotation of the motor rotor of the horizontal compressor, the high-pressure refrigerant discharged from the upper muffler into the motor cavity cannot enter the crankshaft oil passage through the oil outlet channels on the crankshaft, thereby reducing the pressure at each oil outlet channel on the crankshaft. Therefore, by effectively utilizing the differential pressure pumping principle, it is easy to pump oil effectively, making the oil supply speed faster and increasing the amount of lubricating oil entering the crankshaft oil passage. This invention can universally solve the problem of difficult oil supply in horizontal compressors in the background art. The lubricating oil in the crankshaft oil passage is indirectly discharged into the motor cavity through the oil outlet channels. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0049] An oil baffle assembly for a horizontal compressor, such as Figures 1-21 As shown, the horizontal compressor includes a housing 1, and a motor and a pump body are provided inside the housing 1. The inner cavity of the housing 1 is divided into a motor cavity 101 and a pump body cavity 102 by the upper cylinder cover 6 of the pump body. The motor includes a motor stator 2 and a motor rotor 3. A crankshaft 4 is inserted and fixed in the shaft hole of the motor rotor 3.

[0050] The crankshaft 4 is provided with a crankshaft oil passage 403. One end of the crankshaft oil passage 403 passes through the end face of one end of the crankshaft 4. The other end of the crankshaft oil passage 403 is a blocked oil passage blocking end 40302. The oil passage blocking end 40302 is adjacent to the end face of the other end of the crankshaft 4. The other end of the crankshaft 4 is a crankshaft blocking end 405. The crankshaft blocking end 405 extends out of the shaft hole of the motor rotor 3. The end face of one end of the motor rotor 3 is the first end face 301 of the motor rotor. The first end face 301 of the motor rotor is adjacent to the crankshaft blocking end 405.

[0051] The oil baffle assembly includes an oil baffle plate 15, which is disposed on one side of the first end face 301 of the motor rotor and spaced a certain distance from the first end face 301 of the motor rotor. The oil baffle plate 15 is fixedly connected to the motor rotor 3. The side of the oil baffle plate 15 facing the first end face 301 of the motor rotor is the inner side 1501 of the oil baffle plate. Multiple oil outlet channels 406 connected to the crankshaft oil channel 403 are opened on the crankshaft 4 at the position between the inner side 1501 of the oil baffle plate and the first end face 301 of the motor rotor. The oil baffle plate 15 is used to isolate each oil outlet channel 406 from the motor cavity 101.

[0052] This invention, through the cooperation of the oil baffle 15 and the crankshaft 4, can isolate the oil outlet channels 406 on the crankshaft 4 from the motor cavity 101, while the oil outlet channels 406 are connected to the crankshaft oil channel 403. In this way, during the high-speed rotation of the motor rotor 3 of the horizontal compressor, the high-pressure refrigerant discharged from the upper muffler 5 into the motor cavity 101 cannot enter the crankshaft oil channel 403 through the oil outlet channels 406 on the crankshaft 4, thereby reducing the pressure at the oil outlet channels 406 on the crankshaft 4. Therefore, by effectively utilizing the differential pressure pumping principle, it is easy to pump oil effectively, making the oil supply speed faster and increasing the amount of lubricating oil entering the crankshaft oil channel 403. This invention can universally solve the problem of difficult oil supply in horizontal compressors in the background art. The lubricating oil in the crankshaft oil channel 403 is indirectly discharged into the motor cavity 101 through the oil outlet channels 406.

[0053] In one embodiment, such as Figures 1-4 , Figures 8-11 as well as Figures 15-19 As shown, a counterweight 16 is provided between the oil baffle 15 and the motor rotor 3. The oil baffle 15, the counterweight 16 and the motor rotor 3 are fixedly connected by fasteners.

[0054] By setting the counterweight 16, the rotational inertia of the crankshaft 4 during its rotation along with the motor rotor 3 can be balanced.

[0055] Preferably, the fastener is a bolt 17.

[0056] During assembly, the oil baffle 15 and the counterweight 16 are first assembled onto the motor rotor 3 using bolts 17, and then the crankshaft 4 is pressed into the shaft hole of the motor rotor 3.

[0057] In one embodiment, such as Figures 1-4 as well as Figures 8-11 As shown, a circular crankshaft through hole 1503 is provided on the oil baffle plate 15 at a position corresponding to the crankshaft blocking end 405. The diameter of the crankshaft through hole 1503 is adapted to the outer diameter of the crankshaft 4. The crankshaft blocking end 405 passes through the crankshaft through hole 1503 and the crankshaft 4 and the oil baffle plate 15 are interference fit.

[0058] By pressing the crankshaft 4 into the oil baffle 15, the installation stability of the oil baffle 15 can be improved.

[0059] This includes the initial oil level of the horizontal compressor in the oil baffle assembly of this embodiment. Figure 22 After 90 cycles of operation, the amount of lubricating oil in crankshaft oil passage 403 is sufficient. Figure 23 This demonstrates that the technical solution adopted in this embodiment facilitates efficient oil pumping.

[0060] For the horizontal compressor including the oil baffle assembly in this embodiment, the average pressure P1 in the motor cavity 101 is greater than the average pressure P2 in the pump body cavity 102 within one cycle, but the average pressure P3 at each oil outlet channel 406 on the crankshaft 4 is less than the average pressure P2 in the pump body cavity 102. Figure 24 Therefore, it is convenient to pump oil effectively.

[0061] In one preferred embodiment, such as Figures 1-2 as well as Figures 8-9 As shown, the side of the oil baffle 15 opposite to the inner side 1501 of the oil baffle is the outer side 1502 of the oil baffle, and the end face where the oil passage blocking end 40302 is located is on the same plane as the outer side 1502 of the oil baffle.

[0062] In another preferred embodiment, the oil baffle 15 is annular, and the axis of the crankshaft through hole 1503 coincides with the axis of the oil baffle 15.

[0063] In one embodiment, such as Figures 15-19 As shown, the crankshaft sealing end 405 is opposite to the inner side 1501 of the oil baffle plate and does not pass through the oil baffle plate 15.

[0064] In a first preferred embodiment, the distance between the inner side surface 1501 of the oil baffle plate and the first end face 301 of the motor rotor along the crankshaft 4 axis is expressed in Hz, and the axial distance between the oil passage blocking end 40302 and the crankshaft blocking end 405 is controlled to be 0.1Hz-0.3Hz.

[0065] More preferably, the axial distance between the oil passage blocking end 40302 and the crankshaft blocking end 405 is 0.2 Hz.

[0066] In a second preferred embodiment, the oil baffle 15 is circular, and the axis of the crankshaft 4 coincides with the axis of the oil baffle 15.

[0067] In the third preferred embodiment, such as Figures 15-16 As shown, each oil outlet channel 406 is located on the crankshaft 4 near the oil channel blockage end 40302.

[0068] In one embodiment, such as Figures 3-7 , Figures 10-14 , Figures 17-18 as well as Figures 20-21 As shown, multiple oil outlet channels 406 are distributed at intervals along the circumference of the crankshaft 4.

[0069] Preferably, the spacing between any two adjacent oil outlet channels 406 along the crankshaft 4 circumferential direction is equal.

[0070] In one embodiment, the diameter of the crankshaft oil passage 403 is denoted as Dn, and the oil outlet passage 406 is a rectangular oil outlet groove and / or an oil outlet hole, see Figures 1-18 as well as Figures 20-21 The width of the rectangular oil outlet groove along the crankshaft axis is controlled to be 0.1Dn-0.3Dn, and the diameter of the oil outlet hole is controlled to be 0.1Dn-0.3Dn.

[0071] A horizontal compressor includes the aforementioned oil baffle assembly for a horizontal compressor.

[0072] The pump body of the horizontal compressor also includes an upper muffler 5, an upper cylinder 7, an intermediate plate 8, a lower cylinder 9, a lower cylinder head 10, and a lower muffler 11; the crankshaft 4 passes sequentially through the shaft hole of the upper cylinder head 6, the cavity of the upper cylinder 7, the shaft hole of the intermediate plate 8, the cavity of the lower cylinder 9, and the shaft hole of the lower cylinder head 10. The part of the crankshaft 4 located in the cavity of the upper cylinder 7 is the upper eccentric part 401, and the part located in the cavity of the lower cylinder 9 is the lower eccentric part 402. An upper piston 12 is fixedly fitted on the outer side of the eccentric part 401, and a lower piston 13 is fixedly fitted on the outer side of the lower eccentric part 402; an upper cylinder head external flow hole is provided at the outer edge of the upper cylinder head 6 of the pump body, which connects the motor cavity 101 and the pump body cavity 102; an oil suction port 40301 at one end of the crankshaft oil passage 403 is connected to the pump body cavity 102 through an oil suction pipe 14; a vane 404 is provided in the crankshaft oil passage 403 near the oil suction port 40301.

[0073] The lubricating oil in the pump body cavity 102 is sequentially drawn into the crankshaft oil passage 403 through the oil suction pipe 14 and the oil suction port 40301. Under the action of the rotating vane 404, the lubricating oil in the crankshaft oil passage 403 is indirectly discharged into the motor cavity 101 through each oil outlet passage 406. The lubricating oil in the motor cavity 101 enters the pump body cavity 102 through the upper cylinder head external flow hole at the lower part of the upper cylinder head 6. The lubricating oil in the pump body cavity 102 then enters the oil suction pipe 14 to form a circulation.

[0074] In summary, by cooperating with the crankshaft 4, the present invention can achieve the isolation between each oil outlet channel 406 on the crankshaft 4 and the motor cavity 101, thereby reducing the pressure at each oil outlet channel 406 on the crankshaft 4 and facilitating effective oil pumping.

[0075] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
