Description

Technical Field

[0001] This invention relates to the field of oil distributors, and more particularly to a metering oil distributor for long-distance lubrication. Background Technology

[0002] Industrial machinery requires lubrication at various points. In special environments such as deserts, Gobi, wind power plants, or large production workshops, lubrication points are often far apart. Therefore, to ensure lubricating oil reaches these points smoothly, oil tanks need to be installed near them, which presents a significant structural challenge. Furthermore, when the oil tank and lubrication point are far apart, the large pressure drop limits the distance for long-distance lubrication, reducing the lubrication system's capacity. Additionally, during long-distance lubrication, insufficient oil enters the distributor, resulting in uneven oil distribution across lubrication points and making precise control of the oil level difficult.

[0003] Therefore, there is an urgent need for a long-distance lubrication oil metering device to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide a metering oil dispenser for long-distance lubrication.

[0005] To achieve the above objectives, the remote lubrication oil metering distributor provided by the present invention includes a valve seat, a main shaft, a power output disc, a driven disc, a plunger, and a metering valve. The valve seat has a motion channel, an oil inlet channel, and an oil outlet channel, which are respectively connected to the oil inlet channel and the oil outlet channel. The main shaft is rotatably mounted on the valve seat. The power output disc is mounted on the main shaft, and the driven disc is mounted on the main shaft and can tilt and oscillate on the main shaft. A push head protrudes from one side of the power output disc toward the driven disc, and the push head abuts against the driven disc. The plunger is axially slidably mounted in the motion channel, and one end of the plunger is connected to one side of the driven disc. The metering valve is installed in the oil outlet channel and has at least an oil reservoir. In the oiling and discharging states, the rotation of the main shaft drives the power output disc to rotate, causing the pusher head to press against one side of the driven disc. This causes the driven disc to tilt and sway to one side, pushing the plunger into the motion channel. The plunger pushes the oil in the motion channel towards the discharge channel. The oil opens the metering valve, switching it to the oil storage state for oil storage. The continued rotation of the main shaft drives the power output disc to rotate, causing the pusher head to press against the other side of the driven disc. This causes the driven disc to tilt and sway to the other side, pulling the plunger out of the motion channel. The increased space in the motion channel creates negative pressure, attracting oil from the inlet channel into the motion channel. The metering valve switches to the oil discharging state, cutting off the connection between the motion channel and the discharge channel, and discharging the stored oil.

[0006] Preferably, the metering valve includes a guide tube, a spring, a sealing ring, and a plug. The oil discharge channel has an oil passage, and the plug is configured to selectively open or close the oil passage. The guide tube has an oil discharge flow channel. The sealing ring is installed in the guide tube and can slide along the axial direction of the guide tube. The periphery of the sealing ring abuts against the wall of the oil discharge channel. The spring abuts against the sealing ring and has a constant tendency to push the sealing ring closer to the plug. One end of the guide tube forms an open end and is aligned with the plug. The sealing ring encloses an oil storage space in the oil discharge channel. When the plunger pushes the oil in the movement channel into the oil discharge channel, the plug is pushed open, opening the oil passage and blocking the open end. The oil flows into the oil storage space through the oil passage. The oil pushes the sealing ring away from the plug, causing the volume of the oil storage space to continuously increase. When the plunger is pulled out of the movement channel, the plug is attracted and blocks the oil passage. The spring pushes the sealing ring closer to the plug, causing the volume of the oil storage space to continuously decrease. The oil flows into the oil discharge flow channel.

[0007] Preferably, the sealing ring is slidably fitted onto the conduit.

[0008] Preferably, the pusher head extends in an arc shape along the circumference of the power output plate on one side surface of the power output plate, and the height of the pusher head continuously decreases.

[0009] Preferably, the driven disc is mounted on the spindle via a first bearing.

[0010] Preferably, the plunger includes a plunger body and a connecting rod, the outer wall of the plunger body is adapted to the side wall of the motion channel, one end of the connecting rod is connected to the plunger body, and the other end of the connecting rod is hinged to one side of the driven disc.

[0011] Preferably, the diameter of the plug is larger than the diameter of the connecting rod.

[0012] Preferably, the spring is fitted onto the conduit.

[0013] Preferably, the opening end of the conduit is positioned close to the oil inlet, and a placement space is formed between the two, with the plug placed in the placement space.

[0014] Preferably, the valve seat includes a first valve body and a second valve body, the first valve body is mounted on the second valve body, the first valve body and the second valve body enclose an accommodating space, the power output plate and the driven plate are disposed in the accommodating space, the motion channel, the oil inlet channel and the oil outlet channel are disposed on the second valve body, the main shaft is rotatably mounted on the first valve body through a second bearing, and the main shaft is also rotatably mounted on the second valve body through a third bearing.

[0015] Compared to existing technologies, in this invention, as the spindle rotates continuously, the metering valve constantly switches between an oil storage state and an oil dispensing state. Since the amount of oil stored in the metering valve is essentially the same when it is in the oil storage state, the amount of oil dispensed when it is in the oil dispensing state is also essentially the same, thus enabling metered oil dispensing. Furthermore, the metering valve of this invention is not directly connected to the oil tank. Instead, a movement channel is provided within the valve seat. Oil flows from the inlet channel into the movement channel for temporary storage, and the temporarily stored oil is then pumped out to the outlet channel by a plunger. Therefore, the inlet channel does not need to maintain a constant pressure, allowing the metering distributor of this invention to be connected to the oil tank remotely for remote oil pumping.

[0021] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] like Figure 1 As shown, this invention discloses a long-distance lubrication oil metering dispenser 100, which includes a valve seat 10, a main shaft 20, a power output disc 30, a driven disc 40, a plunger 50, and a metering valve 60. The valve seat 10 has a motion channel 11, an oil inlet channel 12, and an oil outlet channel 13, with the motion channel 11 communicating with both the oil inlet channel 12 and the oil outlet channel 13. The main shaft 20 is rotatably mounted on the valve seat 10. The power output disc 30 is mounted on the main shaft 20, and the driven disc 40 is mounted on the main shaft 20 and can tilt and oscillate on the main shaft 20. A push head 31 protrudes from one side of the power output disc 30 toward the driven disc 40, and the push head 31 abuts against the driven disc 40. The plunger 50 is slidably mounted in the motion channel 11, with one end of the plunger 50 connected to one side of the driven disc 40. The metering valve 60 is installed in the oil outlet channel 13. The metering valve 60 has at least... Figure 5 The oil storage status shown and Figure 4The oiling state is shown. The rotation of the main shaft 20 drives the power output disc 30 to rotate, causing the push head 31 to press against one side of the driven disc 40, causing the driven disc 40 to tilt and sway to one side, pushing the plunger 50 into the motion channel 11. The plunger 50 pushes the oil in the motion channel 11 to the oil discharge channel 13, and the oil pushes open the metering valve 60, causing the metering valve 60 to switch to the oil storage state for oil storage. The continued rotation of the main shaft 20 drives the power output disc 30 to rotate, causing the push head 31 to press against the other side of the driven disc 40, causing the driven disc 40 to tilt and sway to the other side, pulling the plunger 50 out of the motion channel 11. The space in the motion channel 11 increases, creating a negative pressure that attracts oil from the oil inlet channel 12 into the motion channel 11. At this time, the metering valve 60 switches to the oiling state, disconnecting the connection between the motion channel 11 and the oil discharge channel 13, and expelling the stored oil.

[0023] In this invention, as the main shaft 20 rotates continuously, the metering valve 60 continuously switches between an oil storage state and an oil dispensing state. Since the amount of oil stored in the metering valve 60 when it is in the oil storage state is essentially the same, the amount of oil dispensed when it is in the oil dispensing state is also essentially the same, thus enabling metered oil dispensing. Furthermore, the metering valve 60 of this invention is not directly connected to the oil tank, but rather a movement channel 11 is provided within the valve seat 10. Oil first flows from the inlet channel 12 into the movement channel 11 for temporary storage, and then the plunger 50 dispenses the temporarily stored oil into the outlet channel 13. Therefore, the oil supply metering distributor 100 of this invention does not require multiple oil tanks; multiple lubrication areas only need one oil source and one oil circuit. Equipped with one oil supply metering distributor 100 of this invention, precise metered lubrication can be achieved. The reciprocating motion of the plunger 50 provides a large suction force, and the inlet channel 12 is connected to the oil source, drawing lubricating oil / grease into the movement channel 11. The oil is pumped out to the drain channel 13, allowing the oil supply metering distributor 100 of this invention to be connected to the oil tank at a distance, realizing long-distance oil pumping. This improves the stability of long-distance oil supply, avoids lubrication failure caused by high-pressure rupture of the oil pipeline, extends the service life of the oil pipeline, simplifies the lubrication system, reduces the use of other components, lowers the failure rate of the lubrication system, realizes interrupted oil power supply for terminal lubrication, increases the uniformity of oil supply, ensures the accuracy of oil supply, and improves the reliability of the lubrication system. It can adapt to harsh working conditions, appropriately control the speed of the spindle 20, and adjust the oil supply frequency and the amount of oil supplied per unit time. The oil supply metering distributor 100 of this invention can be used for centralized lubrication of multiple devices in harsh environments such as deserts and Gobi, such as wind power generation, docks, and large production workshops.

[0024] like Figure 1 , Figure 4 and Figure 5As shown, the metering valve 60 includes a conduit 61, a spring 62, a sealing ring 63, and a plug 64. The oil drain channel 13 has an oil passage 131, and the plug 64 is configured to selectively open or close the oil passage 131. The conduit 61 has an oil drain channel 611. The sealing ring 63 is installed in the conduit 61 and can slide axially along the conduit 61. The sealing ring 63 abuts against the wall of the drain channel 13. The spring 62 abuts against the sealing ring 63 and constantly pushes the sealing ring 63 close to the plug 64. One end of the conduit 61 forms an open end 612 aligned with the plug 64. The sealing ring 63 encloses an oil storage space 132 in the oil drain channel 13. When the plunger 50 pushes the oil in the movement channel 11 towards the drain channel 13, the plug 64 is pushed open, opening the oil port 131 and blocking the opening end 612. The oil flows into the oil storage space 132 through the oil port 131. The oil pushes the sealing ring 63 away from the plug 64, causing the volume of the oil storage space 132 to continuously increase. When the plunger 50 is pulled out of the movement channel 11, the plug 64 is attracted and blocks the oil port 131. The spring 62 pushes the sealing ring 63 closer to the plug 64, causing the volume of the oil storage space 132 to continuously decrease, and the oil flows into the drain channel 611. Preferably, the sealing ring 63 is slidably fitted onto the guide tube 61, allowing the sealing ring 63 to slide smoothly and stably along the guide tube 61. Preferably, the spring 62 is fitted onto the guide tube 61 to enhance the installation stability of the spring 62.

[0025] like Figure 1 and Figure 2 As shown, the push head 31 extends in an arc shape along the circumference of the power output plate 30 on one side surface of the power output plate 30, and the height of the push head 31 continuously decreases. This design allows the power output plate 30 to smoothly and orderly push the driven plate 40 to tilt and swing.

[0026] like Figure 1 As shown, the driven disk 40 is mounted on the main shaft 20 via the first bearing 41 so that the driven disk 40 is stably mounted on the main shaft 20.

[0027] like Figure 1 As shown, the plunger 50 includes a plunger body 51 and a connecting rod 52. The outer wall of the plunger body 51 is adapted to the side wall of the motion channel 11. One end of the connecting rod 52 is connected to the plunger body 51, and the other end of the connecting rod 52 is hinged to one side of the driven disc 40. Preferably, the diameter of the plunger body 51 is larger than the diameter of the connecting rod 52.

[0028] like Figure 4 and Figure 5As shown, the open end of the conduit 61 is positioned close to the oil inlet 131, forming a placement space 65 between them. The plug 64 is disposed within the placement space 65. It is worth noting that the width of the placement space 65 is not large, but it allows the plug 64 to slide within a certain range. Due to the limited width of the placement space 65, the plug 64 is also restricted from detaching from the placement space 65.

[0029] like Figure 1 As shown, the valve seat 10 includes a first valve body 14 and a second valve body 15. The first valve body 14 is mounted on the second valve body 15, and the first valve body 14 and the second valve body 15 enclose a receiving space 16. The power output disc 30 and the driven disc 40 are disposed in the receiving space 16. The motion channel 11, the oil inlet channel 12, and the oil outlet channel 13 are disposed on the second valve body 15. The main shaft 20 is rotatably mounted on the first valve body 14 via a second bearing 70, and the main shaft 20 is also rotatably mounted on the second valve body 15 via a third bearing 80.

[0030] In the embodiments provided by the present invention, in order to realize multi-point oil pumping, multiple sets of plungers 50 are provided, and correspondingly multiple sets of motion channels 11, oil inlet channels 12 and oil outlet channels 13 and other supporting structures are provided.

[0031] The following is a brief description of the working process of the long-distance lubrication oil metering distributor 100 of the present invention: The rotation of the main shaft 20 drives the power output disk 30 to rotate, and the push head 31 moves to the position where... Figure 1 At the indicated position, the pusher head 31 presses against one side of the driven plate 40, thereby pushing the plunger 50 into the motion channel 11. The plunger 50 pushes the oil temporarily stored in the motion channel 11 in the previous round towards the drain channel 13, opening the metering valve 60 and allowing the oil to flow into the storage space 132. The main shaft 20 continues to rotate, driving the power output plate 30 to rotate, causing the pusher head 31 to press against the other side of the driven plate 40. The driven plate 40 tilts and sways to the other side, pulling the plunger 50 out of the motion channel 11. The increased space in the motion channel 11 creates a negative pressure, attracting oil from the inlet channel 12 into the motion channel 11. At this time, the metering valve 60 switches to the oil-filling state, preventing oil from flowing into the storage space 132. The spring 62 presses the sealing ring 63 against the plug 64, reducing the volume of the storage space 132. The oil flows into the guide tube 61 through the open end 611 and finally flows out.

[0032] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
