Description

Technical Field

[0001] The present application relates to the technical field of bearings, and more particularly to a flange bearing with grease storage. Background Art

[0002] A flanged bearing is a special type of bearing with a flange. It typically consists of an outer ring, an inner ring, rolling elements, and a cage. The flange design facilitates mounting the bearing on mechanical equipment, providing additional support and stability. Flange bearings can withstand radial and axial loads. The rolling elements roll between the inner and outer rings, reducing friction and achieving efficient rotational motion. They are widely used in various industrial fields, such as machinery manufacturing, the automotive industry, and automated equipment, providing critical support and transmission functions for stable operation.

[0003] In traditional flange bearing applications, lubrication is usually done by adding grease once during installation or use. The grease added once will gradually consume after the bearing has been running for a period of time, especially at high speeds, high loads or harsh working environments, where the grease consumption rate is faster. When the grease is insufficient, the friction coefficient inside the bearing will increase, resulting in increased wear and heat, thereby reducing the bearing's service life and working efficiency.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] Reference Figure 1-Figure 5 A flange bearing with grease storage includes a bearing body 1 and a flange 12. A plurality of rollers 2 are provided inside the bearing body 1. A cavity 3 is provided inside one side of the bearing body 1. A storage component is provided inside the cavity 3.

[0029] The storage component includes an oil storage bag 4, and a lubrication unit is provided on one side of the oil storage bag 4. The oil storage bag 4 is used to store grease. The lubrication unit includes a leakage net 7 and a connecting belt 9. The leakage net 7 and the connecting belt 9 are used to timely lubricate multiple rollers 2 when the bearing body 1 is working.

[0030] Reference Figure 1-Figure 5 The oil storage bag 4 is located inside the cavity 3, and a plurality of openings 8 are opened on the inner wall of one side of the oil storage bag 4. The plurality of openings 8 are arranged corresponding to the plurality of rollers 2. A fixing ring 5 is provided on one side of the interior of the bearing body 1. A plurality of oil leakage holes 6 are opened inside the fixing ring 5. The plurality of oil leakage holes 6 are arranged corresponding to the plurality of rollers 2. The number of leakage nets 7 is set to multiple, and the plurality of leakage nets 7 are respectively arranged inside the corresponding oil leakage holes 6. The number of connecting belts 9 is set to multiple, and the plurality of connecting belts 9 are all arranged between the oil storage bag 4 and the fixing ring 5. One end of each connecting belt 9 is respectively connected to the corresponding opening 8, and the other end of each connecting belt 9 is respectively connected to the corresponding oil leakage hole 6. The material of the oil storage bag 4, the leakage net 7 and the connecting belt 9 are all made of elastic material.

[0031] The oil storage assembly can continuously lubricate the roller 2 when it is working. The specific lubrication method is that the oil storage bag 4 is located inside the cavity 3 of the bearing body 1 and is used to store grease. When the bearing body 1 is working, the roller 2 rolls between the inner and outer rings to generate friction. Since a plurality of openings 8 are provided on the inner wall of one side of the oil storage bag 4, and these openings 8 are arranged corresponding to the roller 2, a plurality of oil leakage holes 6 corresponding to the roller 2 are also provided on the fixing ring 5 on one side of the inner side of the bearing body 1. A leakage net 7 is provided inside each oil leakage hole 6. The oil storage bag 4 and the fixing ring 5 are connected by a plurality of connecting belts 9 made of elastic material. One end of the connecting belt 9 is connected to the opening 8 of the oil storage bag 4, and the other end is connected to the oil leakage hole 6;

[0032] During the operation of the bearing body 1, with the rotation of the roller 2 and the frictional heat generated, the oil storage bag 4 will be subject to certain pressure and temperature changes. Since the oil storage bag 4, the leakage net 7 and the connecting belt 9 are all made of elastic materials, the internal temperature of the bearing body 1 will increase during operation. Through thermal expansion and contraction and pressure, the grease in the oil storage bag 4 will enter the connecting belt 9 through the opening 8, and then flow along the connecting belt 9 to the corresponding oil leakage hole 6. When the grease passes through the leakage net 7, it will seep out in a relatively uniform manner and drip directly onto the working roller 2, providing continuous lubrication for the roller 2. The elastic material oil storage bag 4, the leakage net 7 and the connecting belt 9 can automatically adjust the outflow speed and flow rate of the grease according to the pressure change, ensuring that the roller 2 can be lubricated in time and in an appropriate amount under different working conditions, thereby reducing the friction between the roller 2 and the inner and outer rings, and improving the service life and working efficiency of the bearing body 1.

[0033] The oil storage component can provide continuous lubrication for the roller 2, so that the roller 2 and the inner and outer rings always maintain a good lubrication state, reduce the friction coefficient, reduce wear and heat, and ensure the stable operation of the bearing body 1. For example, in mechanical equipment that runs continuously for a long time, continuous lubrication can avoid failure of the bearing body 1 due to insufficient lubrication, improve the reliability of the equipment, and make the bearing run smoother and reduce energy loss, which helps to improve the working efficiency of the mechanical equipment and reduce energy consumption. Through timely lubrication of the oil storage component, the degree of wear on the surface of the roller 2 can be reduced, and the accuracy and shape of the roller 2 and the inner and outer rings can be maintained, thereby extending the service life of the bearing body 1.

[0034] Reference Figure 4 Slide bars 10 are provided on both sides of the outer wall of the oil storage bag 4, and slide grooves 11 are provided on both sides of the inner wall of the cavity 3. Each slide bar 10 is slidably connected to the corresponding slide groove 11.

[0035] The oil storage bag 4 can be quickly positioned and accurately installed in the cavity 3 of the bearing body 1 through the slide bar 10 and the slide groove 11, thereby improving the installation efficiency.

[0036] Reference Figure 2 The outer wall of each roller 2 is provided with a collar 13 , and a connecting piece 14 is provided between every two collars 13 .

[0037] The multiple collars 13 are connected together by connecting pieces 14 so that the spacing between the rollers 2 can be kept relatively stable.

[0038] Reference Figure 1 The bottom of the cover 15 is snap-fitted to the top of the cavity 3 , and a plurality of extension blocks 16 are provided on one side of the cover 15 . A positioning pin 17 is provided on one side of each extension block 16 , and each positioning pin 17 is connected to the bearing body 1 through the corresponding extension block 16 .

[0039] By means of the snap connection and the arrangement of the positioning pins 17 , the cover 15 can be easily installed.

[0040] Working principle: When the bearing body 1 is working, the roller 2 rolls between the inner and outer rings to generate friction. Since a plurality of openings 8 are provided on the inner wall of one side of the oil storage bag 4, and these openings 8 are arranged corresponding to the roller 2, a plurality of oil leakage holes 6 corresponding to the roller 2 are also provided on the fixing ring 5 on one side of the inner side of the bearing body 1. A leakage net 7 is provided inside each oil leakage hole 6. The oil storage bag 4 and the fixing ring 5 are connected by a plurality of connecting belts 9 made of elastic material. One end of the connecting belt 9 is connected to the opening 8 of the oil storage bag 4, and the other end is connected to the oil leakage hole 6.

[0041] During the operation of the bearing body 1, with the rotation of the roller 2 and the frictional heat generated, the oil storage bag 4 will be subject to certain pressure and temperature changes. Since the oil storage bag 4, the leakage net 7 and the connecting belt 9 are all made of elastic materials, the internal temperature of the bearing body 1 will increase during operation. Through thermal expansion and contraction and pressure, the grease in the oil storage bag 4 will enter the connecting belt 9 through the opening 8, and then flow along the connecting belt 9 to the corresponding oil leakage hole 6. When the grease passes through the leakage net 7, it will seep out in a relatively uniform manner and drip directly onto the working roller 2, providing continuous lubrication for the roller 2. The elastic material oil storage bag 4, the leakage net 7 and the connecting belt 9 can automatically adjust the outflow speed and flow rate of the grease according to the pressure change, ensuring that the roller 2 can be lubricated in time and in an appropriate amount under different working conditions, thereby reducing the friction between the roller 2 and the inner and outer rings, and improving the service life and working efficiency of the bearing body 1.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
