Description

Technical Field

[0001] This utility model relates to the field of liner technology, and more specifically, to a novel liner assembly. Background Technology

[0002] A bushing is a tubular structure that is fitted over the outside of a shaft or other component. When used in bearings, it fits tightly around the outer or inner ring of the bearing, providing protection, support, and auxiliary lubrication. For example, in the bearings of motors, bushings prevent external impurities from entering the bearing and avoid wear caused by these impurities. By mating with the bearing housing, bushings evenly distribute the load borne by the bearing, enhancing stability. At the same time, the inner surface of the bushing can be designed with special structures, such as oil grooves, which help the lubricating oil to be distributed more evenly during bearing operation, improving lubrication conditions and extending the bearing's service life.

[0003] However, in actual use, the lubricating oil used in existing liners is easily affected by environmental factors. In high-temperature environments, the viscosity of the lubricating oil decreases, leading to a decline in its lubrication performance. It cannot effectively form an oil film of sufficient thickness between the liner and the contacting parts, increasing the friction coefficient between the parts and thus accelerating the wear of the equipment and shortening its service life. In low-temperature environments, the viscosity of the lubricating oil increases significantly, and its fluidity deteriorates, which may make it difficult to distribute evenly to the parts that need lubrication, resulting in insufficient lubrication in some areas and causing equipment malfunctions. This undoubtedly brings great trouble to actual use.

[0004] Secondly, existing liner assemblies typically rely on lubricating oil to reduce friction between components during actual operation, thereby minimizing wear and ensuring stable operation and long-term use of the equipment. However, as the usage time increases, the performance of the lubricating oil gradually deteriorates, necessitating periodic replacement. The current replacement method has significant drawbacks; the process is extremely cumbersome. When changing the lubricating oil, workers must disassemble the liner. Only by disassembling the liner can the degraded lubricating oil be completely drained, allowing for the replacement with new lubricating oil. This complex process not only consumes substantial manpower, resources, and time but also easily causes accidental damage to the liner and related components during disassembly, affecting the overall performance and service life of the equipment.

[0005] In view of this, we propose a novel liner assembly. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this invention is to provide a novel liner assembly to solve the problems mentioned in the background art.

[0008] 2. Technical Solution

[0009] A novel liner assembly includes a base, a connecting cylinder disposed on one outer wall of the base, a fixing shell disposed on the outer wall of the connecting cylinder, a connecting ring plate welded and fixed to the inner circumference of the connecting cylinder, an outer bushing welded and fixed to the outer wall of the connecting cylinder, an inner bushing welded to the outer wall of the connecting ring plate, an oil inlet pipe and an oil outlet pipe disposed on the outer circumference of the outer bushing, and a fixing cap ring welded between the ends of the inner bushing and the outer bushing.

[0010] Preferably, the outer wall of the base has mounting holes and a through opening.

[0011] Preferably, the interior of the fixed shell is hollow, and an air outlet is provided on the outer wall of the fixed shell.

[0012] Preferably, the outer bushing has an air passage cavity inside, and the outer walls at both ends of the outer bushing have through holes, with the through hole on the right end of the outer bushing corresponding to a plurality of air outlets.

[0013] Preferably, the outer circumferential wall of the inner liner has a slot, and a plurality of the slots are movably engaged with ball bearings, the circumferential surface of the ball bearings extending into the interior of the inner liner.

[0014] Preferably, an oil groove is provided between the outer bushing and the inner bushing, and the oil groove is filled with lubricating oil.

[0015] Preferably, the oil inlet pipe is internally threaded with a threaded post, and a sealing rubber plug is connected to the end of the threaded post.

[0016] Preferably, a fan is fixedly connected to the outer wall of the fixed housing, an electric heating grid is connected to the inner wall of the fixed housing, the fixed housing is in communication with the interior of the connecting cylinder, a temperature sensor is connected to the outer wall of the connecting ring plate, and the sensing end of the temperature sensor extends into the oil sump and contacts the lubricating oil.

[0017] 3. Beneficial effects

[0018] Compared to existing technologies, the advantages of this invention are as follows: During actual use, when the inner wall of the inner bushing mates with the shaft, the ball bearings contact the shaft. As the shaft rotates, the ball bearings rotate, coming into contact with and becoming coated with lubricating oil. The lubricant on the ball bearings adheres to the circumferential surface of the shaft along its rotation, achieving lubrication and improving its lubrication performance. During this process, the temperature sensor monitors the temperature of the lubricating oil, thus determining its actual temperature. If the lubricating oil temperature is detected to be too low, the electric heating network can be activated, followed by the airflow generated by the fan entering the connecting cylinder, and then flowing through the connecting cylinder into… The air passage inside the outer bushing allows hot air to heat the lubricating oil, reducing the risk of a significant increase in oil viscosity and decreased fluidity in low-temperature environments, which would otherwise affect lubrication. When the lubricating oil temperature is too high, the electric heating grid can be stopped, and the fan will create a cooling effect. The airflow will quickly dissipate the lubricating oil's temperature, reducing the risk of decreased lubrication performance due to reduced oil viscosity in high-temperature environments. This would prevent the formation of a sufficiently thick oil film between the inner bushing and the contact parts, improving its practicality and flexibility, and reducing the impact of the environment on the lubrication effect.

[0019] When the lubricating oil needs to be changed, the threaded columns inside the multiple drain pipes and inlet pipes can be rotated to remove the multiple sealing rubber plugs. Then, lubricating oil can be injected directly into the inlet pipe, and the lubricating oil can be changed by squeezing. Waste oil can be discharged from the multiple drain pipes at the bottom by squeezing, which can improve the efficiency of personnel changing the lubricating oil. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A novel bushing assembly includes a base 100, a connecting cylinder 120 disposed on one outer wall of the base 100, a fixing shell 121 disposed on the outer wall of the connecting cylinder 120, a connecting ring plate 130 welded and fixed to the inner circumference of the connecting cylinder 120, an outer bushing 200 welded and fixed to the outer wall of the connecting cylinder 120, an inner bushing 300 welded to the outer wall of the connecting ring plate 130, an oil inlet pipe 220 and an oil outlet pipe 230 disposed on the outer circumference of the outer bushing 200, and a fixing cap ring 250 welded between the ends of the inner bushing 300 and the outer bushing 200. The fixing cap ring 250 facilitates the limiting of lubricating oil and reduces its leakage.

[0030] Specifically, the outer wall of the base 100 has mounting holes 110 and through holes.

[0031] Furthermore, the interior of the fixed shell 121 is hollow, and the outer wall of the fixed shell 121 has an air outlet 124 to facilitate the delivery of airflow generated by the fan 122.

[0032] Furthermore, an air passage cavity 210 is provided inside the outer bushing 200, and through round holes 240 are provided on the outer walls at both ends of the outer bushing 200. The through round hole 240 on the outer wall at the right end of the outer bushing 200 corresponds to multiple air outlets 124, so that the airflow generated by the fan 122 can act inside the air passage cavity 210.

[0033] Furthermore, the inner bushing 300 has slots on its outer circumference, and multiple slots are used to engage ball bearings 310. The circumferential surface of the ball bearings 310 extends into the inner bushing 300, which facilitates the use of the ball bearings 310 to provide lubrication.

[0034] It is worth noting that an oil groove is provided between the outer bushing 200 and the inner bushing 300, and the oil groove is filled with lubricating oil 320.

[0035] In some embodiments, lubricating oil 320 is a molybdenum disulfide solid lubricant, which is in the prior art.

[0036] It is worth noting that the oil inlet pipe 220 has a threaded post 222 inside, and a sealing rubber plug 221 is connected to the end of the threaded post 222 to facilitate sealing of the multiple oil drain pipes 230 and the oil inlet pipe 220.

[0037] In addition, a fan 122 is fixedly connected to the outer wall of the fixed housing 121, an electric heating grid 123 is connected to the inner wall of the fixed housing 121, the fixed housing 121 is connected to the inside of the connecting cylinder 120, a temperature sensor 131 is connected to the outer wall of the connecting ring plate 130, and the sensing end of the temperature sensor 131 extends into the oil tank and contacts the lubricating oil 320.

[0038] In some embodiments: the temperature sensor 131 is a device capable of sensing temperature changes and converting them into an output signal. Common temperature sensors, such as thermistors, operate on the principle that the resistance of semiconductor materials changes significantly and regularly with temperature. When the external temperature changes, the resistance of the thermistor changes accordingly. The circuit converts the resistance change into a voltage or current change, which, after processing by a signal conditioning circuit, outputs an electrical signal corresponding to the temperature, thereby achieving accurate temperature measurement and monitoring. This is existing technology, and commonly available models can be selected. The fan 122 consists of a motor blade and a housing, which is also existing technology. The heating mesh 123 typically consists of a heating wire, an insulating layer, and a metal mesh. Its structural design involves evenly winding the heating wire around the insulating layer. The insulating layer isolates the current and ensures safe use. The metal mesh supports and fixes the heating wire and enhances the stability of the overall structure. The working principle is based on the thermal effect of current. When current passes through the heating wire, due to the resistance of the heating wire, electrical energy is converted into heat energy, thereby raising the temperature of the heating wire and generating heat. Heat is transferred to the surrounding environment through thermal conduction, thermal convection and thermal radiation to heat the surrounding space or objects. Temperature sensor 131, fan 122 and electric heating grid are all electrically connected in series with an external controller to facilitate the control of the temperature of the lubricating oil 320. Secondly, they can all be powered by an external power supply. All of the above belong to the prior art.

[0039] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0040] Working principle: In actual use, when the inner wall of the inner bushing 300 mates with the shaft, it can contact the shaft through the ball bearings 310. During the rotation of the shaft, the ball bearings 310 rotate, and the ball bearings 310 come into contact with and become stained with the lubricating oil 320. The lubricant 320 on the ball bearings 310 will adhere to the circumferential surface of the shaft along the rotation of the shaft, thereby achieving a lubrication effect and improving its lubrication performance. During this process, the temperature sensor 131 can monitor the temperature of the lubricating oil 320 to determine its actual temperature. When the temperature of the lubricating oil 320 is detected to be too low, the electric heating network 123 can be activated, and then the airflow generated by the fan 122 enters the interior of the connecting cylinder 120, and then enters through the connecting cylinder 120. The hot air passes through the air passage 210 inside the outer bushing 200 to heat the lubricating oil 320, reducing the situation where the viscosity of the lubricating oil 320 increases significantly and its fluidity decreases in low-temperature environments, thus affecting the lubrication effect. When the temperature of the lubricating oil 320 is too high, the electric heating grid 123 can be stopped, and the fan 122 will create a cooling effect. The airflow will quickly dissipate the temperature of the lubricating oil 320, reducing the decrease in viscosity of the lubricating oil 320 in high-temperature environments, which would lead to a decrease in its lubrication performance and prevent the formation of a sufficiently thick oil film between the inner bushing 300 and the contact parts. This improves its practicality and flexibility in use and reduces the impact of the environment on the lubrication effect of the lubricating oil 320.

[0041] When it is necessary to replace the lubricating oil 320, the threaded post 222 inside the multiple drain pipes 230 and the inlet pipe 220 can be rotated to remove the multiple sealing rubber plugs 221. Then, lubricating oil 320 can be injected directly into the inlet pipe 220, and the lubricating oil 320 can be replaced by squeezing. Waste oil can be discharged from the multiple drain pipes 230 at the bottom by squeezing, which can improve the efficiency of personnel replacing the lubricating oil 320.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
