Description

Technical Field

[0001] The utility model relates to the field of automatic oil injection equipment, and particularly relates to an intelligent oil adding device for mechanical bearings. Background Art

[0002] An automatic oiler is an automated device for lubricating mechanical equipment. During the operation of the equipment, it can deliver lubricating oil to each lubrication-required part regularly and quantitatively, thus ensuring the normal operation of the equipment and extending its service life.

[0003] However, for existing automatic oilers, whether it is timed oil supply or oil supply at intervals according to the working period of the machine, it is a pre-set oil supply method based on experience. This oil supply method cannot dynamically adjust the oil supply amount of the bearing according to changes in the working conditions of the machine, ambient temperature, etc. Whether the grease in the bearing is sufficient or lacking, it will automatically add grease at regular intervals according to the pre-set time interval. If the bearing lacks grease lubrication before the pre-set time interval arrives, it will cause bearing wear, thus shortening its service life; and when the bearing grease is already sufficient and still automatically adds grease, the excessive grease will also lead to problems such as poor lubrication and temperature rise, resulting in bearing wear, and further shortening its service life.

In practical applications, the electromagnetic coil is electrically connected to the vibration sensor through a wire. The vibration sensor is responsible for monitoring vibration signals and analyzing whether there is a lack of oil in the bearing. Once it is determined that the bearing has abnormal vibration, the vibration sensor will supply power to the electromagnetic coil through the wire. At this time, the magnetic field polarity generated by the electromagnetic coil is the same as that of the magnet bar, generating a repulsive force, causing the end plate on the side close to the electromagnetic coil to tilt up, while the end plate on the side close to the air outlet pipe drops. This action prompts the thimble to press down on the valve nozzle, thereby quantitatively releasing the gas in the air storage cylinder. Subsequently, the high-pressure gas pushes the piston, slowly injecting the grease into the bearing to complete the lubrication process. The collaborative design of the above device realizes the seamless combination of vibration monitoring and automatic lubrication.

During the three stages of before, during, and after grease filling, the vibration sensor continuously analyzes the lubrication state of the bearing to ensure the best lubrication effect. This system ensures that the bearing automatically replenishes grease at the first time when lubrication is required, effectively preventing bearing wear and extending its service life. At the same time, this system also avoids the problem of excessive grease addition caused by timed automatic lubrication.

In this application, by using a wire harness storage box, the wire harnesses of the electromagnetic coil and the pressure detection sensor are integrated and connected through wires, realizing the information exchange between the electromagnetic coil, the pressure detection sensor, and the vibration sensor. This design enables precise control of the specific amount of grease filled during the grease filling process, not only significantly improving the efficiency and accuracy of the grease filling operation, but also ensuring the controllability and traceability of the filling process through a real-time feedback mechanism. Specifically, through the precise control of the electromagnetic coil and the sensitive capture of the pressure change during the filling process by the pressure detection sensor, the system can dynamically adjust the injection rate and amount of grease, avoiding overfilling or underfilling, thereby extending the service life of the equipment and reducing maintenance costs.

[0040] Embodiment:

[0041] An intelligent oil filling device for a mechanical bearing, comprising an oil storage device 10, a gas storage device 20 and a vibration sensor 30. The oil storage device 10 and the gas storage device 20 are detachably connected;

[0042] The oil storage device 10 includes an oil storage cylinder 110 with an open bottom. An oil outlet pipe 120 is provided at the top of the oil storage cylinder 110, and a piston 130 is slidably connected to the inner bottom of the oil storage cylinder 110;

[0043] The gas storage device 20 includes a gas storage cylinder 210. A gas valve and a top contact device 60 are provided on the top surface of the gas storage cylinder 210;

[0044] The top contact device 60 includes an end plate 610 and a support column 620. A top pin 630 and a spring-up component 640 are respectively detachably connected to both ends of the end plate 610. An electromagnetic coil 70 is provided in the spring-up component 640;

[0045] Wherein, the support column 620 is fixed on the top surface of the gas storage cylinder 210. The end plate 610 is hinged to the support column 620. The top pin 630 is located above the gas valve. The electromagnetic coil 70 is electrically connected to a wire harness storage box 50 provided outside the gas storage cylinder 210. The wire harness storage box 50 is electrically connected to the vibration sensor 30 through a wire 40.

[0046] It should be noted that the electromagnetic coil 70, the top contact device 60, and the vibration sensor 30 together constitute an automatic lubrication system. In practical applications, the electromagnetic coil 70 is electrically connected to the vibration sensor 30 through the wire 40. The vibration sensor 30 is responsible for monitoring vibration signals and analyzing whether the bearing is lacking oil. Once it is determined that the bearing has abnormal vibration, the vibration sensor 30 will supply power to the electromagnetic coil 70 through the wire 40. At this time, the magnetic field polarity generated by the electromagnetic coil 70 is the same as the polarity of the magnet bar 6420, generating a repulsive force, causing the end plate 610 on the side close to the electromagnetic coil 70 to tilt up, while the end plate 610 on the side close to the air outlet pipe 220 drops. This action causes the top pin 630 to press down on the valve nozzle 230, thereby quantitatively releasing the gas in the gas storage cylinder 210. Subsequently, the high-pressure gas pushes the piston 130 to slowly inject the grease into the bearing, completing the lubrication process.

[0047] It should be noted that the collaborative design of the above device realizes the seamless combination of vibration monitoring and automatic lubrication. By monitoring the operating state of the bearing, the system can automatically detect problems at the initial stage when the lubrication performance begins to decline, and immediately control the automatic lubrication system to replenish grease in a timely manner. During the three stages of before, during, and after grease filling, the vibration sensor 30 continuously analyzes the lubrication state of the bearing to ensure the best lubrication effect. This system ensures that the bearing automatically replenishes grease at the first moment when lubrication is needed, effectively preventing bearing wear and extending its service life. At the same time, this system also avoids the problem of excessive grease addition caused by timed automatic lubrication. In addition, this automatic lubrication system also has the characteristics of high flexibility and intelligence. The system can automatically adjust the lubrication frequency and grease volume according to the actual operating conditions of the bearing and environmental factors to achieve the optimal lubrication effect. For example, under extreme working conditions, such as high temperature, heavy load, or high-speed operation, the system will automatically increase the lubrication frequency and grease volume to ensure that the bearing is fully lubricated and reduce the risk of wear and failure.

[0048] In combination with the accompanying drawings of the specification Figures 1 - 11 As shown, the popping-up component 640 includes a magnet plate 6410, a magnet rod 6420, and a plug-in board 6430. One end of the plug-in board 6430 is fixed to the end face of the magnet plate 6410 facing the end plate 610, and the other end of the plug-in board 6430 is clamped with a card slot opened on the end face of the end plate 610. Among them, the plug-in board 6430 and the end plate 610 are fixedly connected by a bolt 650. The magnet rod 6420 is connected to the bottom surface of the magnet plate 6410 and is located inside the electromagnetic coil 70. The thimble 630 is screwed to the bottom surface of the end plate 610 and is vertically corresponding to the air valve.

[0049] It is explained that the combined design of the magnet plate 6410 and the magnet rod 6420 enables the top-touch device 60 to respond quickly under the action of the electromagnetic coil 70. When the electromagnetic coil 70 is energized, the generated magnetic field interacts with the magnet rod 6420 to generate a repulsive force, causing the end plate 610 to tilt up. This design ensures that the thimble 630 can accurately squeeze the valve nozzle 230, thereby achieving the purpose of quantitatively releasing gas.

[0050] Specifically, in order to further improve the stability and reliability of the system, the vibration monitoring unit can select a wireless vibration sensor 30 according to the actual situation. It is equipped with a built-in lithium battery and can perform real-time analysis and processing of the vibration signals of the bearings. Among them, both the oil storage device 10 and the gas storage device 20 are made of corrosion-resistant materials. The filling gas inside the gas storage device 20 is nitrogen. Since nitrogen is an inert gas and does not react with other substances, it can effectively protect the substances inside the air outlet cylinder from the influence of oxygen and moisture in the air. Moreover, nitrogen can exclude the oxygen inside the air outlet cylinder, reduce the oxidation reaction of metals or other materials, extend the service life of the equipment, and can also prevent moisture from condensing inside the cylinder, avoiding corrosion or other damages caused by dampness, thereby ensuring the stability and safety of the gas storage device 20 during use.

[0051] Combined with the accompanying drawings of the specification Figures 1 - 11 As shown, the air valve includes an outlet pipe 220 and a valve stem 230. The outlet pipe 220 is arranged on the top surface of the gas storage cylinder 210, and the valve stem 230 is clamped inside the outlet pipe 220. The diameter of the outlet pipe 220 is larger than the diameter of the thimble 630.

[0052] It is explained that the design of the air valve ensures the smooth flow and precise control of the gas. Among them, the diameter of the outlet pipe 220 is larger than the diameter of the thimble 630, so that the thimble 630 will not be overly obstructed during the process of pressing down the valve stem 230, thus ensuring the smooth release of the gas. At the same time, the clamping method of the valve stem 230 enables it to be quickly replaced, facilitating maintenance and adjustment.

[0053] Combined with the accompanying drawings of the specification Figures 1 - 11 As shown, an outer connector 250 is arranged on the bottom surface of the oil storage cylinder 110 along its circular edge. The inner wall surface of the outer connector 250 is provided with internal threads. An inner connector 140 is arranged on the top surface of the gas storage cylinder 210 along its circular edge. The outer wall surface of the inner connector 140 is provided with external threads. The oil storage cylinder 110 is threadedly connected to the gas storage cylinder 210. A first step is formed at the connection between the oil storage cylinder 110 and the outer connector 250, and a second step is formed at the connection between the gas storage cylinder 210 and the inner connector 140. A first sealing ring 150 and a second sealing ring 240 are respectively installed on the first step and the second step. Among them, the top surface of the outer connector 250 abuts against the second sealing ring 240, and the inner connector 140 abuts against the first sealing ring 150.

[0054] It is explained that the threaded connection design between the oil storage cylinder 110 and the gas storage cylinder 210 ensures the sealing performance and stability of the device. By installing sealing rings on the corresponding steps of the outer connecting piece 250 and the inner connecting piece 140, it can effectively prevent the leakage of grease and gas at the connection. The first sealing ring 150 and the second sealing ring 240 are in close contact with the top surface of the outer connecting piece 250 and the inner connecting piece 140 respectively, forming a reliable sealing effect. This design not only ensures the sealing performance of the lubrication system, but also facilitates disassembly and maintenance, improving the operability of the system.

[0055] Specifically, the threaded design of the outer connecting piece 250 at the bottom of the oil storage cylinder 110 and the inner connecting piece 140 at the top of the gas storage cylinder 210 enables the oil storage device 10 and the gas storage device 20 to be easily disassembled and connected. This design allows for quick operation when the oil storage cylinder 110 or the gas storage cylinder 210 needs to be replaced, without the need for complex tools or procedures. At the same time, this design also facilitates the replacement of the oil storage cylinder 110 and the gas storage cylinder 210 with different capacities or specifications according to different lubrication requirements in practical applications, increasing the flexibility of the system.

[0056] Combined with the accompanying drawings of the specification Figures 1 - 11 As shown, the oil storage device 10 further includes a sealing cover 160 and a handle 170. The sealing cover 160 is screwed onto the outside of the oil injection pipe opened on the top surface of the oil storage cylinder 110. Among them, the handle 170 is arranged on the top surface of the oil storage cylinder 110, facilitating the upward lifting of the piston 130 to facilitate the injection of grease into the oil storage cylinder 110. The design of the sealing cover 160 not only ensures the sealing of the oil storage cylinder 110, but also facilitates the replenishment and replacement of grease. The setting of the handle 170 enables the operator to easily lift the piston 130, thereby injecting grease into the oil storage cylinder 110 to ensure the normal operation of the lubrication system.

[0057] It is explained that the combined design of the sealing cover 160 and the handle 170 makes the operation of the oil storage device 10 more convenient. The screwing method of the sealing cover 160 ensures that there is no leakage during the injection of grease, and it is also convenient for disassembly and cleaning. The design of the handle 170 enables the operator to easily lift the piston 130 without using additional tools, thus improving work efficiency.

[0058] Combined with the accompanying drawings of the specification Figures 1 - 11As shown, a pressure detection sensor 80 is further provided on the top surface of the air storage cylinder 210. The pressure detection sensor 80 is electrically connected to the wire harness storage box 50. By using the wire harness storage box 50, the wire harnesses of the electromagnetic coil 70 and the pressure detection sensor 80 are integrated and connected through the wire 40, realizing the information exchange between the electromagnetic coil 70, the pressure detection sensor 80, and the vibration sensor 30. This design enables precise control of the specific oil injection volume during the grease filling process, not only significantly improving the efficiency and accuracy of the grease filling operation, but also ensuring the controllability and traceability of the filling process through a real-time feedback mechanism. Specifically, through the precise control of the electromagnetic coil 70 and the sensitive capture of the pressure change during the filling process by the pressure detection sensor 80, the system can dynamically adjust the injection rate and volume of the grease, avoiding overfilling or underfilling, thereby extending the service life of the equipment and reducing the maintenance cost.

[0059] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
