Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, in particular to a spherical roller bearing with a lubrication function. Background Art

[0002] Spherical roller bearings are a type of bearing with strong radial and axial load capacity. They are a type of rolling bearing that can withstand large impact loads and vibrations and are suitable for environments with relatively harsh operating conditions. Currently, spherical roller bearings are mainly composed of a combination of rings and rolling elements, which are then used in combination with bearing seats. However, most spherical roller bearings do not have a lubrication structure, and it is difficult to lubricate the inside of the spherical roller bearing during use. The increase in friction can easily lead to an increase in the temperature of the spherical roller bearing during operation. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a spherical roller bearing with a lubrication function, which solves the problem that most spherical roller bearings do not have a lubrication structure, it is difficult to lubricate the inside of the spherical roller bearing during use, and the increase in friction easily leads to an increase in temperature of the spherical roller bearing during operation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-aligning roller bearing with lubrication function, comprising a seat body, a ferrule connected to the seat body, a sealing ring clamped in the seat body, a bearing body rotatably connected in the ferrule, a roller provided in the bearing body, an oil cylinder connected to the bearing body, an oil pipeline connected to the outside of the oil cylinder, a sponge plug connected to the oil cylinder, a push rod slidably connected in the oil cylinder, a connecting plate connected to the push rod, a fixed plate connected to the outside of the oil cylinder, a moving rod connected under the connecting plate, and a spring connected to the outer shell of the moving rod.

[0005] As a further solution of the utility model: the sealing ring is overlapped outside the ferrule, and the moving rod is slidably connected inside the fixed plate.

[0006] As a further solution of the utility model: the connecting plate is connected to the fixed plate through a spring, and a fixed plate is connected under the moving rod.

[0007] As a further solution of the utility model: the sealing ring is externally connected with an L-shaped plate, and the L-shaped plate is clamped outside the seat body.

[0008] As a further solution of the utility model: bolts are arranged in the L-shaped plate, and the L-shaped plate is connected to the seat body through the bolts.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The spherical roller bearing with lubrication function is provided with an oil cylinder, an oil delivery pipe, a push rod, a connecting plate, a moving rod and a spring. After the lubricating oil is delivered to the oil cylinder through the oil delivery pipe, the connecting plate is pressed. When the lubricating oil is under pressure, it will flow out through the sponge plug. When the moving rod slides in the fixed plate, it will drive the spring to deform. When the lubricating oil is delivered, the connecting plate is released and the push rod is reset by the action of the spring. The spherical roller bearing cooperates with the connecting plate, the moving rod and the spring so that the push rod can realize the function of reciprocating movement in the oil cylinder, and can evenly deliver the lubricating oil in the oil cylinder to the bearing body, thereby avoiding the phenomenon that the temperature of the spherical roller bearing increases due to long-term friction, and effectively ensuring the adaptability of the spherical roller bearing.

[0011] 2. The spherical roller bearing with lubrication function is provided with a sealing ring, an L-shaped plate and bolts. When the bearing body is connected with the ferrule, the sealing ring will fit with the ferrule when it is snapped into the seat body, and the L-shaped plate will be connected to the seat body by bolts, so that the sealing ring can play a certain sealing role on the spherical roller bearing and prevent dust in the air from entering the interior of the bearing body.

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-4As shown, the utility model provides a technical solution: a self-aligning roller bearing with lubrication function, including a seat body 1, a ring 2 is connected inside the seat body 1, a sealing ring 3 is clamped inside the seat body 1, a bearing body 4 is rotatably connected inside the ring 2, a roller 5 is arranged inside the bearing body 4, an oil cylinder 6 is connected outside the bearing body 4, an oil pipeline 7 is connected outside the oil cylinder 6, and a sponge plug 14 is connected inside the oil cylinder 6;

[0019] The sealing ring 3 is connected to an L-shaped plate 15 on the outside, and the L-shaped plate 15 is clamped on the outside of the seat body 1. Bolts 16 are arranged inside the L-shaped plate 15, and the L-shaped plate 15 is connected to the seat body 1 through the bolts 16. By providing the L-shaped plate 15 and the bolts 16, when the sealing ring 3 is clamped in the seat body 1, the L-shaped plate 15 will be connected to the seat body 1 through the bolts 16, so that the sealing ring 3 and the seat body 1 can achieve a function of rapid assembly, and the sealing ring 3 is easy to replace later;

[0020] A push rod 9 is slidably connected inside the oil cylinder 6, a connecting plate 10 is connected to the push rod 9, a fixed plate 8 is connected to the outside of the oil cylinder 6, a moving rod 11 is connected below the connecting plate 10, and a spring 13 is connected to the outer surface of the moving rod 11. By setting the fixed plate 8, when the connecting plate 10 is subjected to a thrust or a pull, the connecting plate 10 will drive the moving rod 11 to slide inside the fixed plate 8, so that the fixed plate 8 plays a certain guiding role in the movement of the moving rod 11, thereby preventing the moving rod 11 from getting stuck when moving;

[0021] The sealing ring 3 is overlapped outside the ferrule 2, the moving rod 11 is slidably connected in the fixed plate 8, and the connecting plate 10 is connected to the fixed plate 8 through the spring 13. By setting the spring 13, when the connecting plate 10 is pressed to move, the connecting plate 10 will drive the spring 13 to deform, so that the spring 13 plays a certain supporting role for the connecting plate 10, and when the connecting plate 10 loses resistance, it will be reset by the spring 13;

[0022] A fixed plate 12 is connected under the movable rod 11. By setting the fixed plate 12, when the connecting plate 10 is pulled, the connecting plate 10 will drive the movable rod 11 to slide in the fixed plate 8. When the movable rod 11 moves to an appropriate position, the fixed plate 12 will contact the fixed plate 8, so that the fixed plate 12 plays a certain limiting role on the position of the connecting plate 10, thereby preventing the connecting plate 10 from falling off when being pulled.

[0023] The working principle of the utility model is:

[0024] When the spherical roller bearing is in use, the bearing body 4 can be connected to the ring 2, and then the sealing ring 3 can be clamped in the seat body 1. When the sealing ring 3 and the ring 2 are fully fitted, the L-shaped plate 15 on the side will contact the seat body 1, and the L-shaped plate 15 will be connected to the seat body 1 through the bolt 16. When the spherical roller bearing is in operation, the lubricating oil can be delivered to the oil cylinder 6 through the oil pipe 7, and then when the connecting plate 10 is pressed, the connecting plate 10 will drive the push rod 9 to slide in the oil cylinder 6, and the lubricating oil in the oil cylinder 6 will flow out through the sponge plug 14 when it is under pressure, and the moving rod 11 will drive the spring 13 to deform when it slides in the fixed plate 8. When the lubricating oil is delivered, the connecting plate 10 is released, and the push rod 9 will be reset by the action of the spring 13.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
