Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission components, specifically a high-precision bearing with oil storage and lubrication function. Background Technology

[0002] Traditional bearings are widely used in industry and machinery to support rotating components and reduce frictional losses. However, existing bearing designs can present some inconveniences in installation and maintenance, limiting their flexibility and efficiency in certain applications. Therefore, a new type of bearing structure with a bearing housing is needed to meet higher performance requirements. The installation process of traditional bearings can be complex, causing workers to spend excessive time and effort on installation and maintenance. Secondly, the stability and reliability of the bearings may be limited, affecting the performance of the overall system. Furthermore, some bearings may be difficult to disassemble, which can cause difficulties during maintenance and replacement.

[0003] Bearings, as indispensable key components in machinery, primarily support rotating or sliding parts and achieve smooth movement by reducing friction. By bearing loads and reducing friction between rotating parts, bearings extend the service life of mechanical equipment and are widely used in various mechanical equipment such as electric motors, automobiles, and home appliances. Their structure typically consists of an outer ring, an inner ring, rolling elements, and a cage. The outer and inner rings respectively mate with the equipment and rotating parts, while the rolling elements, such as steel balls and rollers, move freely between the inner and outer rings, effectively reducing friction. The cage ensures the stable arrangement of the rolling elements, prevents collisions, and improves the stability and lifespan of the bearing. For example, a bearing with lubrication and oil leakage prevention function disclosed in patent announcement number CN217873819U includes a bearing component, two sealing assemblies respectively disposed on both sides of the bearing component, and two first arc plates and two second arc plates symmetrically rotated and connected to the interior of the bearing component. An oil injection assembly is disposed on the bearing component, which includes an outer bearing ring and an inner bearing ring disposed inside the outer bearing ring. A cage is rotatably engaged between the inner ring and the outer ring of the bearing. The outer wall of the cage is symmetrically embedded with multiple rollers in a ring array. By utilizing the arrangement of the bearing components and two sealing assemblies, two first arc plates and two second arc plates can each form a sealing ring, thereby sealing both sides of the bearing components and reducing the rate of lubricant leakage inside the bearing components. However, in the process of oiling and grease application, the sealing gaskets installed on both ends of the inner ring and outer ring of the bearing still need to be removed to expose the cage and rolling elements. Removing the sealing gaskets increases the difficulty of maintenance work. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision bearing with oil storage and lubrication function to solve the problems mentioned in the background art. Although the bearing structure can be well applied, it usually only has one set of ball bearings, which results in general bearing performance. The bearing structure has an oil storage cavity between the retaining ring and the outer ring for grease to be stored. During the oil injection and lubrication maintenance operation, the oil injection gun can inject grease into the oil storage cavity through the one-way valve core, so that the bearing components do not need to be disassembled, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision bearing with oil storage and lubrication function, comprising a bearing base 1, a lower bearing seat 2 fixed at the center of the top of the bearing base 1, an upper bearing seat 3 above the lower bearing seat 2, the bottom end of the upper bearing seat 3 contacting the top end of the lower bearing seat 2, bearings being provided in the circular grooves of the lower bearing seat 2 and the upper bearing seat 3, the bearing comprising an outer ring 6, an inner ring 8 and an oil storage cavity, an array of balls 7 sandwiched between the outer ring 6 and the inner ring 8, retaining rings on both sides of the outer ring 6, the retaining rings being filled with grease, the oil storage cavity being located between the retaining rings and the outer ring 6, and protrusions integrally formed on the front and rear outer walls of the outer ring 6, and a one-way valve core for allowing grease to enter the oil storage cavity 10 is installed inside the protrusions.

[0006] In one embodiment, the bearing base 1 has waist-shaped holes 101 on both sides inside, and both ends of the waist-shaped holes 101 extend to the outside of the bearing base 1.

[0007] In one embodiment, the outer surfaces of both sides of the lower bearing seat 2 are provided with lower bearing plates 4, and the inner wall of the lower end of the lower bearing plate 4 is fixedly connected to the outer surface of the bearing base 1.

[0008] In one embodiment, the outer surfaces of both sides of the upper shaft seat 3 are provided with upper shaft plates 5, and the bottom end of the upper shaft plate 5 touches the top end of the lower shaft plate 4.

[0009] In one embodiment, hexagonal bolts 9 are installed on both sides of the top end of the upper shaft seat 3, and the bottom end of the hexagonal bolts 9 passes through the upper shaft seat 3 and is threadedly connected to the top end of the lower shaft seat 2.

[0010] In one embodiment, the outer ring 6 and the array of balls 7 are provided with two sets of symmetrically distributed balls.

[0011] In one embodiment, the inner ring 8 has two sets of threaded holes, which are symmetrically distributed on both sides of the inner ring 8 in groups of two. The threaded holes are threadedly connected to a locking member, and the upper surface of the locking member has a hexagonal groove.

[0012] Compared with existing technologies, this high-precision bearing with oil storage and lubrication function not only makes the bearing structure perform well under heavy loads or vibration loads, ensuring the smooth operation of the bearing structure, but also improves the convenience of bearing structure maintenance and achieves the purpose of easy positioning and placement of the bearing structure. The outer ring of the bearing is provided with retaining rings on both sides and filled with grease, which helps to reduce friction, lower temperature, effectively prevent the bearing from overheating, improve the bearing's life and performance, and has a strong load capacity. The inner ring, two sets of outer rings and a set of balls can effectively share and bear the load from different directions. This helps reduce the load on each bearing group, lightening its workload and thus improving the overall system's load-bearing capacity. By tightening the hex bolts, the lower end of the hex bolts is unscrewed to the outside of the lower bearing seat, allowing the upper bearing seat to be pulled upwards and removed from the top of the lower bearing seat. The upper bearing plate is then removed from the top of the lower bearing plate, facilitating the disassembly of the bearing outer ring and other related bearing components, thereby improving the convenience of bearing structure maintenance. With the two oblong holes, the bearing base is placed on the mounting platform, and the oblong holes are aligned with the threaded holes reserved on the mounting platform. Then, by using bolts that pass through the oblong holes and screw them into the threaded holes reserved on the mounting platform, the bearing base can be bolted and positioned on the mounting platform, thus achieving the purpose of easy positioning and placement of the bearing structure.
