Description

Technical Field

[0001] This utility model relates to the field of water pump bearing technology, specifically to a self-lubricating water pump bearing that prevents impurities. Background Technology

[0002] Self-lubricating water pump bearings are innovative core components of water pumps, achieving highly efficient self-lubrication through a unique structural design. These bearings feature an annular oil reservoir and oil guide holes. The reservoir stores lubricating oil, which flows through the guide holes to the contact points between the rolling elements and the inner and outer rings. This eliminates the need for an additional lubrication system, ensuring continuous and effective lubrication during operation and significantly reducing frictional resistance.

[0003] For example, patent CN217502301U discloses a self-lubricating bearing, including an inner bearing ring and an outer bearing ring; ball grooves are formed on the outer side of the inner bearing ring and the inner side of the outer bearing ring, and balls are rotatably arranged inside the ball grooves. A spiral first oil reservoir is formed on each ball; sealing mechanisms are connected to both sides of the inner and outer bearing rings. However, existing water pump bearings are prone to impurity intrusion during operation. These impurities, such as mud, sand, and rust, enter the bearing, accelerating wear and causing significant frictional resistance during operation. This not only increases energy consumption but also reduces the bearing's service life, and in severe cases, can even lead to pump failure and shutdown. Furthermore, it is difficult to continuously add lubricating oil; when adding lubricating oil, the bearing must be removed, which is inconvenient.

[0004] Therefore, in order to solve such problems, we propose a self-lubricating water pump bearing that is resistant to impurities. Utility Model Content

[0005] The purpose of this invention is to provide a self-lubricating water pump bearing that prevents impurities from entering, in order to solve the problem mentioned in the background art where impurities, such as mud, sand, and rust, enter the bearing and accelerate wear, resulting in greater frictional resistance during operation. This not only increases energy consumption but also reduces the bearing's service life, and in severe cases, can even cause the water pump to malfunction and shut down. Furthermore, it is difficult to continuously add lubricating oil, and when adding lubricating oil is needed, the bearing must be removed, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating water pump bearing that prevents impurities, comprising a base, a top seat on the top of the base, a sleeve penetrating through the middle of the top surface of the top seat, an annular groove on the inner wall of the sleeve, an oil inlet channel movably connected inside the sleeve, annular rubber blocks uniformly fixedly connected to the outer wall of the oil inlet channel, an oil inlet cavity inside the oil inlet channel, an oil storage body fixedly connected to the top of the oil inlet channel, an oil storage cavity inside the oil storage body, a circular hole at the rear of the top of the oil storage body, the circular hole communicating with the oil storage cavity, and an oil delivery pipe fixedly connected inside the circular hole.

[0007] Furthermore, a shaft is fixedly connected to the groove at the top of the base, and an oil inlet hole is provided in the middle of the top surface of the shaft, which is connected to the inner hole of the sleeve.

[0008] Furthermore, fixing blocks are fixedly connected to both outer walls of the base and the top seat, and threaded bolts are threadedly connected to the fixing blocks, and the base and the top seat are fixedly connected by the threaded bolts.

[0009] Furthermore, a mounting plate is fixedly connected to one side of the top sleeve of the top seat, and a vertical plate is rotatably connected to the mounting plate. A sliding groove is opened on the side of the vertical plate near the sleeve, and a slider is movably connected in the sliding groove. A connecting plate is fixedly connected to the outer end of the slider, and a threaded rod is threadedly connected to the side of the connecting plate away from the slider. A threaded cylinder is threadedly connected to the threaded rod, and the bottom of the threaded rod is fixedly connected to the top of the top seat.

[0010] Furthermore, a base plate is fixedly connected to the bottom of the base, and fixing bolts are movably connected to the four corners of the base plate.

[0011] Furthermore, the slider is movably sleeved on the outer wall of the slide rod fixedly connected inside the slide groove, and the upright plate and the connecting plate are slidably connected to the slider through the slide groove.

[0012] Furthermore, the annular groove and the annular rubber block are the same size, and the sleeve and the oil inlet channel are sealed to the annular rubber block through the annular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the impurity-resistant self-lubricating water pump bearing adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The impurity-proof self-lubricating water pump bearing has a tight fit between the annular groove and the annular rubber block, which is like installing a solid protective barrier for the oil inlet channel. It can effectively resist the intrusion of impurities such as mud, sand and rust, preventing them from entering the shaft body. This greatly reduces the wear of the shaft body and alleviates the problem of increased frictional resistance caused by impurities. As the frictional resistance decreases, energy consumption also decreases, and the service life of the bearing is significantly extended. This not only reduces the number of times the water pump fails and stops, but also improves the stability and reliability of the water pump operation, ensuring that it can work continuously and efficiently.

[0015] (2) The impurity-proof self-lubricating water pump bearing, through the oil reservoir and oil delivery pipe, has an oil storage chamber inside the oil reservoir that can store a sufficient amount of lubricating oil, and the oil delivery pipe connected to it is connected to an external oil tank. During the operation of the water pump, when the shaft needs to be replenished with lubricating oil, there is no need to disassemble the entire bearing. The lubricating oil in the oil reservoir can be easily and conveniently delivered to the various parts of the bearing that need lubrication through the oil delivery pipe, so as to achieve continuous lubrication of the bearing, ensure that the bearing is always in good working condition, effectively reduce friction loss, and improve the overall operating efficiency and stability of the water pump.

[0016] Furthermore, a sophisticated adjustment mechanism is constructed through the cooperation of the connecting plate, threaded rod, and threaded cylinder. The threaded rod provides a stable support structure for the entire adjustment process, while the threaded cylinder is tightly connected to the threaded rod via threads. Utilizing the principle of threaded transmission, precise linear movement is achieved. In actual operation, when it is necessary to install or remove the oil inlet channel, simply rotate the threaded cylinder. As the threaded cylinder slowly rotates on the threaded rod, it moves smoothly axially according to the guidance of the threads, thereby driving the connecting plate to move synchronously. Since the connecting plate and the annular rubber block are interconnected, the annular rubber block will precisely adjust its position under this driving force, enabling more easy and faster completion of related operations and significantly improving maintenance efficiency. This not only reduces downtime required for equipment maintenance and lowers maintenance costs but also provides a strong guarantee for the long-term stable operation of the water pump.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides the following technical solution: a self-lubricating water pump bearing that prevents impurities.

[0026] Example 1: A self-lubricating water pump bearing that prevents impurities, using components such as annular groove 21 and annular rubber block 221 to seal the oil inlet channel 22, preventing mud, rust, etc., from entering the shaft body 11, which would accelerate the wear of the shaft body 11. Figure 1 - Figure 4As shown, a self-lubricating water pump bearing with impurity prevention includes a base 1, a top seat 12 on the top of the base 1, a sleeve 2 penetrating through the center of the top surface of the top seat 12, an annular groove 21 on the inner wall of the sleeve 2, an oil inlet channel 22 movably connected inside the sleeve 2, annular rubber blocks 221 uniformly fixedly connected to the outer wall of the oil inlet channel 22, an oil inlet cavity 222 inside the oil inlet channel 22, an oil reservoir 23 fixedly connected to the top of the oil inlet channel 22, an oil reservoir cavity 231 inside the oil reservoir 23, and a circular hole at the rear of the top of the oil reservoir 23. 232, the round hole 232 is connected to the oil storage chamber 231, the round hole 232 is fixedly connected to the oil supply pipe 24, the groove at the top of the base 1 is fixedly connected to the shaft 11, the top surface of the shaft 11 is provided with an oil inlet hole 111, and the oil inlet hole 111 is connected to the inner hole of the sleeve 2, the bottom of the base 1 is fixedly connected to the base plate 4, and the four feet of the base plate 4 are movably connected to the fixing bolts 41, the annular groove 21 and the annular rubber block 221 are the same size, and the sleeve 2 and the oil inlet channel 22 are sealed to the annular rubber block 221 through the annular groove 21.

[0027] First, fix the base plate 4 in the required position using the fixing bolts 41 at the four feet. Fix the shaft 11 in the groove at the top of the base 1. The oil inlet hole 111 in the middle of the top surface of the shaft 11 is connected to the inner hole of the sleeve 2. Then, place the top seat 12 on the top of the base 1. Fix the two together using the threaded bolts 131 on the fixing blocks 13 on both sides of the base 1 and the top seat 12. The annular groove 21 on the inner wall of the sleeve 2 and the annular rubber block 221 uniformly fixed to the outer wall of the oil inlet channel 22 are the same size. The two fit tightly to achieve a sealed connection, preventing impurities such as mud and rust from entering the shaft 11. The lubricating oil is stored in the oil storage chamber 231 of the oil storage body 23. The round hole 232 at the rear of the top of the oil storage body 23 is connected to the oil storage chamber 231. The oil supply pipe 24 fixedly connected in the round hole 232 can be used to add lubricating oil. The lubricating oil flows through the oil inlet chamber 222 of the oil inlet channel 22 and through the oil inlet hole 111 of the shaft 11 to the parts that need lubrication, thus achieving a self-lubricating function.

[0028] Example 2: Unlike Example 1, the connection between the connecting plate 32, threaded rod 321, and threaded cylinder 33 allows for adjustment of the position of the annular rubber block 221 on the oil inlet channel 22, making the installation and disassembly of the oil inlet channel 22 more convenient. Figures 5-6As shown, fixing blocks 13 are fixedly connected to both outer walls of the base 1 and the top seat 12. Threaded bolts 131 are threaded onto the fixing blocks 13, and the base 1 and the top seat 12 are fixedly connected by the threaded bolts 131. A mounting plate 3 is fixedly connected to one side of the top sleeve 2 of the top seat 12. A vertical plate 31 is rotatably connected to the mounting plate 3. A sliding groove 311 is provided on the side of the vertical plate 31 near the sleeve 2. A slider 312 is movably connected in the sliding groove 311. A connecting plate 32 is fixedly connected to the outer end of the slider 312. A threaded rod 321 is threadedly connected to the side of the connecting plate 32 away from the slider 312. A threaded cylinder 33 is threaded onto the threaded rod 321, and the bottom of the threaded rod 321 is fixedly connected to the top of the top seat 12. A base plate 4 is fixedly connected to the bottom of the base 1, and fixing bolts 41 are movably connected to the four feet of the base plate 4.

[0029] When performing position adjustment operations such as installation or disassembly of the oil inlet channel 22, only the threaded cylinder 33 needs to be rotated slightly. The threaded connection between the threaded cylinder 33 and the threaded rod 321 allows the threaded cylinder 33 to move smoothly in a straight line along the threaded rod 321 when it rotates. This movement will synchronously drive the connecting plate 32 connected to it, causing the connecting plate 32 to move as well. The connecting plate 32 is tightly connected to the slider 312, which is precisely installed in the groove 311 of the vertical plate 31. In this way, when the connecting plate 32 moves, the slider 312 will slide smoothly in the groove 311, thereby accurately adjusting the position of the annular rubber block 221 on the oil inlet channel 22. This greatly simplifies the installation and disassembly process of the oil inlet channel 22 and significantly improves work efficiency.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
