DETAILED DESCRIPTION

[0027] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, an oil supply line vibration damping device 10 is provided, comprising a housing 11, which is provided with an oil passage 111. The oil passage 111 has two openings at either end, namely an oil inlet 114 and an oil outlet 115 formed in the housing 11. The oil inlet 114 is connected to the oil pump 20, and the oil outlet 115 is connected to the oil supply line 30. The oil output by the oil pump 20 passes through the oil supply line vibration damping device 10 before entering the oil supply line 30. After being damped by the oil supply line vibration damping device 10, the oil has less fluctuation, thereby reducing the impact damage to the oil supply line 30 caused by the oil flowing through the oil supply line 30.

[0029] When the oil pump 20 is a gear pump, the gear pump draws oil from the oil pump inlet and discharges it from the oil outlet through the gear meshing between the main gear and the auxiliary gear. The periodic meshing of the gears will cause periodic pulses in the oil pumped out by the oil pump 20.

[0030] To this end, the oil supply line vibration damping device 10 further includes a spoiler 12 disposed within the oil passage 111. As the oil flows through the spoiler 12, its pulse waves are disrupted, thereby achieving the purpose of vibration reduction and reducing the degree of damage to the oil supply line 30 caused by the oil flowing through the oil supply line 30. Specifically, in one embodiment, the oil supply line vibration damping device 10 includes multiple spoilers 12 to further enhance the vibration reduction effect.

[0031] Furthermore, the spoiler 12 is movably connected to the housing 11. When oil flows through the spoiler 12, the spoiler 12 can move relative to the housing 11 under the impetus of the oil. Thus, while the spoiler 12 disrupts the oil pulse wave to achieve a vibration reduction effect, it also has a minimal obstruction to the oil flow, thereby preserving the oil flow dynamics as much as possible and maintaining a high oil supply efficiency.

[0032] In some embodiments, the spoiler 12 is rotatably connected to the housing 11, such as Figure 2As shown, the axis of rotation of the spoiler 12 relative to the housing 11 intersects the flow direction of the oil flowing through the spoiler 12. Specifically, in one embodiment, the axis of rotation of the spoiler 12 relative to the housing 11 is perpendicular to the flow direction of the oil flowing through the spoiler 12. As the oil flows through the spoiler 12, the spoiler 12 rotates relative to the housing 11 under the force of the oil.

[0033] Specifically in one embodiment, Figure 2 As shown, the spoiler 12 includes a spiral rod. Optionally, the spoiler 12 can also be in other shapes, which are not specifically limited here.

[0034] The screw rod is rotatably connected to the housing 11 , and the axis of rotation of the screw rod relative to the housing 11 is consistent with the axis of the screw rod.

[0035] In this application, a screw rod refers to a rod-like structure with a spiral pattern on its outer surface. This spiral pattern is recessed within the rod-like structure, and the axis of the screw rod is the axis of the rod-like structure. In some cases, the depth of the recessed spiral pattern is H1, and the radius of the rod-like structure is R1, where H1 is greater than 1 / 2 × R1. In some cases, a screw rod can be understood as a bolt with a deep thread depth.

[0036] The spoiler 12 may be directly rotatably engaged with the housing 11 or the housing 11 may be indirectly rotatably engaged with the spoiler 12 via an intermediate element.

[0037] For example, Figure 2 As shown, in certain embodiments, a support member 13 is provided in the oil passage 111 and is connected to the housing 11. The spoiler 12 is rotatably connected to the support member 13, and the axis of rotation of the spoiler 12 relative to the support member 13 intersects the flow direction of the oil flowing through the spoiler 12. In one specific embodiment, the axis of rotation of the spoiler 12 relative to the support member 13 is perpendicular to the flow direction of the oil flowing through the spoiler 12.

[0038] In one embodiment, Figure 2 As shown, the oil supply line vibration reduction device 10 includes a plurality of spoilers 12. One end of each spoiler 12 is rotatably mounted on a support member 13, and the other end is cantilevered outside the support member 13. The axis of rotation of each spoiler 12 relative to the support member 13 intersects the flow direction of oil flowing through the spoiler 12, and the axial direction of the axis of rotation of each spoiler 12 relative to the support member 13 is consistent with the cantilever direction of the spoiler 12.

[0039] When the oil flows through the oil passage 111 , each spoiler 12 can rotate relative to the support 13 , thereby disrupting the vibration wave of the oil while having little obstruction to the flow of the oil.

[0040] One end of the screw is rotatably connected to the support member 13, and the other end of the screw is suspended outside the support member 13. The axis of rotation of the screw relative to the support member 13 intersects the flow direction of the oil through the screw. The axis of rotation of the screw relative to the support member 13 is consistent with the axis of the screw.

[0041] In some embodiments, one end of the spoiler 12 hanging outside the support member 13 is spaced apart from the housing 11 .

[0042] Specifically, if Figure 2 and Figure 3 As shown, in one embodiment, the support member 13 is a support rod, and the plurality of spoilers 12 are spaced apart along the circumference of the support rod. One end of each spoiler 12 is concentrated on the support rod, and the other ends of each spoiler 12 are distributed in a direction away from the support rod. The axial direction of the spiral rod is perpendicular to the axial direction of the support rod.

[0043] Furthermore, in some embodiments, Figure 3 As shown, the oil supply line vibration damping device 10 further includes a screwing member 15. A socket 131 is defined in the support member 13, and the screwing member 15 is partially inserted into the socket 131. Each spoiler 12 extends into the socket 131 from the side, with the screwing member 15 inserted into the socket 131 in a direction perpendicular to the direction in which the spoiler 12 extends into the socket 131. The screwing member 15 is threadedly engaged with the sidewall of the socket 131, and can be screwed relative to the support member 13 until it abuts the spoiler 12.

[0044] During use, the screw member 15 can be rotated as needed to move the screw member 15 relative to the support member 13, thereby adjusting the abutting force exerted by the screw member 15 on the spoiler 12, and thereby adjusting the power required for the spoiler 12 to move relative to the housing 11. The greater the oil flow rate, the greater the force exerted by the screw member 15 to prevent the spoiler 12 from moving.

[0045] In some embodiments, the screw member 15 partially extends outside the housing 11 to facilitate the user's rotation operation.

[0046] In one embodiment, the spoiler 12 includes a spiral rod, each of which extends into the insertion hole 131 from the side of the insertion hole 131, and the screwing member 15 is inserted into the insertion hole 131 in a direction perpendicular to the direction in which the spiral rod extends into the insertion hole 131. The screwing member 15 can be screwed to a position abutting against the spiral rod.

[0047] Furthermore, if Figure 2As shown, in some embodiments, the oil supply line vibration reduction device 10 further includes a separator 14. The separator 14 is located in the oil passage 111 and is connected to the housing 11. The separator 14 divides the oil passage 111 into an upstream passage 1111 and a downstream passage 1112. A portion of the separator 14 is separated from the housing 11 to form a through-hole, connecting the upstream passage 1111 and the downstream passage 1112. The oil inlet 114 and the upstream passage 1111 are located on the same side of the separator 14, and the oil outlet 115 and the downstream passage 1112 are located on the same side of the separator 14.

[0048] The oil entering from the oil inlet 114 needs to first flow along the upstream channel 1111 to the through hole before entering the downstream channel 1112 and then flowing out from the oil outlet 115. The spoiler 12 can be set in the upstream channel 1111, the downstream channel 1112 or the through hole.

[0049] In one embodiment, the flow direction of the oil in the upstream channel 1111 intersects with the flow direction of the oil in the downstream channel 1112. Figure 2 As shown, the spoiler 12 is located at the connection point between the upstream channel 1111 and the downstream channel 1112. The oil contacts each spoiler 12 while changing its flow direction.

[0050] The partition 14 divides the oil passage 111 into an upstream passage 1111 and a downstream passage 1112 , thereby increasing the passage length from the oil inlet 114 to the oil outlet 115 and effectively controlling the overall length of the housing 11 .

[0051] Specific as Figure 2 As shown, in one embodiment, the flow direction of the oil in the upstream channel 1111 is opposite to the flow direction of the oil in the downstream channel 1112 .

[0052] The support member 13 is disposed at the connection point between the upstream channel 1111 and the downstream channel 1112 , and a plurality of spoilers 12 are distributed at the connection point.

[0053] In one embodiment, Figure 2 As shown, the cross-section of the connection between upstream channel 1111 and downstream channel 1112 is fan-shaped, and the central angle of this fan-shaped circle is greater than 180°. The connection between upstream channel 1111 and downstream channel 1112 is a turning channel, which is a cylindrical space with a fan-shaped cross-section. Both upstream channel 1111 and downstream channel connect to this turning channel from the side.

[0054] One ends of all the spoilers 12 are gathered at the center of the sector, and the other ends of all the spoilers 12 are distributed in a direction away from the center.

[0055] When the oil flows through the steering channel, it flows along an arc path under the drainage effect of the housing 11 and passes through each spoiler 12 in sequence.

[0056] In one embodiment, the support member 13 is disposed at the center of the sector, and one end of each of the spoilers 12 is engaged with the support member 13 at the center. The support rods are arranged along the length of the steering channel.

[0057] The spoiler 12 comprises a spiral rod, one end of each spiral rod is gathered at the center of the circle of the sector, and the other end of each spiral rod is distributed in a direction away from the center of the circle. For example, the axial direction of each spiral rod is consistent with a radial direction of the sector.

[0058] Furthermore, if Figure 2 and Figure 4 As shown, in certain embodiments, the side surface of the separator 14 that forms the upstream channel 1111 with the housing 11 is a first side surface, and the direction along the first side surface from a position close to the oil inlet 114 to the through hole is a first drainage direction, which is consistent with the oil inlet direction of the oil inlet 114. The oil entering from the oil inlet 114 will continue to flow along the initial direction when entering the upstream channel 1111.

[0059] The separator 14 is provided with multiple oil drain slots 141, each connecting the upstream channel 1111 and the downstream channel 1112. If the oil in the upstream channel 1111 is considered as a single entity, it forms a columnar structure. This columnar structure has a tendency to expand outward. In other words, the outer portion is squeezed outward by the inner portion. Therefore, under the action of pressure, the oil entering the upstream channel 1111 will partially and rapidly flow directly from the oil drain slots 141 into the downstream channel 1112, releasing some of the pressure.

[0060] like Figure 2 and Figure 4 As shown, the separator 14 is a separator plate, the length of which is the first flow direction. The oil drain slit 141 runs through both sides of the separator plate, thereby connecting the upstream channel 1111 and the downstream channel 1112. The two long sides of the separator plate are arranged along the first flow direction and are both connected to the housing 11. The short side of the separator plate near the oil inlet 114 is connected to the housing 11, and the short side of the separator plate away from the oil inlet 114 is separated from the housing 11 to form a via.

[0061] like Figure 1 As shown, the housing 11 includes a top plate 112, a bottom plate and a side plate 113. The top plate 112 and the bottom plate have the same shape and are arranged opposite to each other. The side plate 113 is arranged between the top plate 112 and the bottom plate and along the edge of the top plate 112, so that the top plate 112, the bottom plate and the side plate 113 form an oil passage 111, and an oil inlet 114 and an oil outlet 115 are formed on the side plate 113.

[0062] The support member 13 is arranged along the spacing between the top plate 112 and the bottom plate. Specifically, in one embodiment, the axial direction of the support rod aligns with the spacing between the top plate 112 and the bottom plate. The cross-section at the junction of the upstream channel 1111 and the downstream channel 1112 is taken perpendicular to the axial direction of the support rod. The screw member 15 extends through the top plate 112 or the bottom plate and out of the housing 11.

[0063] The two long sides of the partition plate are respectively connected to the top plate 112 and the bottom plate of the shell 11, a short side of the partition plate close to the oil inlet 114 is connected to the side plate 113 of the shell 11, and the other short side of the partition plate is spaced apart from the side plate 113 of the shell 11 to form a process.

[0064] like Figure 2 As shown, in some embodiments, the oil supply line vibration reduction device 10 further includes a vibration reduction hose 16, which is connected to the oil inlet 114. The housing 11 can be connected to the oil pump 20 through the vibration reduction hose 16 to further reduce vibration transmitted from the oil pump 20.

[0065] In yet another embodiment, a chiller is provided, such as Figure 5 As shown, it includes an oil pump 20, an oil supply pipeline 30 and the above-mentioned oil supply pipeline vibration damping device 10, the oil discharge port of the oil pump 20 is connected to the oil inlet 114 in the oil supply pipeline vibration damping device 10, and the oil outlet 115 in the oil supply pipeline vibration damping device 10 is connected to the oil supply pipeline 30.

[0066] During operation, the oil inlet 114 communicates with the oil pump 20, and the oil outlet 115 communicates with the oil supply line 30. The lubricating oil pumped by the oil pump 20 flows through the vibration damping device and into the oil supply line 30. The disruptor in the oil passage 111 disrupts the pulse waves of the lubricating oil entering the passage 111, thereby reducing vibration and minimizing the impact of the lubricating oil on the oil supply line 30. Furthermore, the disruptor 12 is movably connected to the housing 11. Therefore, while disrupting the pulse waves of the lubricating oil and dampening vibration, it also reduces resistance to the flow of the lubricating oil, allowing the lubricating oil to flow smoothly and rapidly, minimizing vibration while preserving the lubricating oil's circulation dynamics.

[0067] Specifically, the vibration-reducing hose 16 is connected between the oil inlet 114 and the oil outlet of the oil pump 20 , and the end of the oil supply line 30 away from the oil outlet 115 can be connected to the oil tank 40 . The vibration-reducing hose 16 can be welded to the oil pump 20 .
