Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, in particular to a sealing structure of a tapered roller bearing. Background Art

[0002] Tapered roller bearings are a commonly used mechanical component, which is mainly used to bear combined radial and axial loads. The current tapered roller bearings are composed of rolling elements, cages and rings, and then connected to the surface of the sealing ring. However, the sealing ring and the bearing are mostly integrated. When the sealing ring is damaged after long-term use, it is difficult to replace it in time, thereby reducing the sealing performance of the tapered roller bearing. The tapered roller bearing needs to be replaced as a whole later. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a sealing structure of a tapered roller bearing, which solves the problem that the sealing ring and the bearing are mostly integrated, and it is difficult to replace the sealing ring in time when it is damaged after long-term use, thereby reducing the sealing performance of the tapered roller bearing, and the tapered roller bearing needs to be replaced as a whole later.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealing structure of a tapered roller bearing, comprising a bearing body, a sealing ring is connected to the outer outer surface of the bearing body, an auxiliary block is connected to the sealing ring, a rotating plate is provided inside the sealing ring, a guide rod is connected to the outside of the rotating plate, a fixed plate is slidably connected inside the auxiliary block, a positioning rod is connected to the fixed plate, a spring is connected to the outer outer surface of the positioning rod, a fixing groove is provided on the rotating plate, and the fixed plate is clamped in the rotating plate.

[0005] As a further solution of the utility model: the positioning rod is slidably connected in the auxiliary block, and the fixing plate is connected in the auxiliary block through a spring.

[0006] As a further solution of the utility model: a threaded hole is provided in the fixing groove, and the guide rod is rotatably connected in the sealing ring.

[0007] As a further solution of the utility model: a bearing member is arranged inside the bearing body, and two grooves are arranged outside the bearing body.

[0008] As a further solution of the utility model: bolts are arranged in the fixing plate, and the fixing plate is connected to the rotating plate through the bolts.

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

[0010] 1. The sealing structure of the tapered roller bearing is provided with a sealing ring, an auxiliary block, a rotating plate, a fixing plate, bolts and a fixing groove. After the sealing ring is sleeved on the surface of the bearing body, a thrust is applied to the rotating plate, and the rotating plate rotates with the guide rod as the center. When the rotating plate is engaged with the auxiliary block, the positioning rod is loosened, and the fixing plate is engaged in the fixing groove and connected to the threaded hole through bolts. The bearing cooperates with the rotating plate, the fixing plate and the bolts, so that the sealing ring and the bearing body can be quickly assembled. When the sealing ring is damaged after long-term use, it can be replaced in time, thereby ensuring the sealing of the tapered roller bearing, and there is no need to replace the tapered roller bearing as a whole later.

[0011] 2. The sealing structure of the tapered roller bearing is provided with a positioning rod and a spring. When the rotating plate rotates, the positioning rod is pulled, and the fixed plate drives the spring to deform when it moves. When the rotating plate is fitted with the auxiliary block, the positioning rod is released, and the fixed plate is reset by the action of the spring. After the reset, the fixed plate is clamped with the rotating plate, thereby playing a certain limiting role in the fixation of the rotating plate and preventing the position of the rotating plate from shifting when it is fixed.

[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 sealing structure of a tapered roller bearing, comprising a bearing body 1, a sealing ring 2 is connected to the outer sleeve of the bearing body 1, an auxiliary block 3 is connected to the sealing ring 2, a rotating plate 6 is arranged inside the sealing ring 2, a guide rod 7 is connected to the outer sleeve of the rotating plate 6, a fixed plate 8 is slidably connected inside the auxiliary block 3, a positioning rod 10 is connected to the fixed plate 8, a spring 11 is connected to the outer sleeve of the positioning rod 10, a fixing groove 12 is provided on the rotating plate 6, and the fixing plate 8 is clamped in the rotating plate 6;

[0019] By providing the guide rod 7, when a thrust is applied to the rotating plate 6, the rotating plate 6 will rotate around the guide rod 7, so that the guide rod 7 plays a certain guiding role in the rotation of the rotating plate 6, thereby preventing the rotating plate 6 from colliding with the sealing ring 2 during rotation;

[0020] The positioning rod 10 is slidably connected in the auxiliary block 3, and the fixing plate 8 is connected in the auxiliary block 3 through the spring 11. By setting the spring 11, when the fixing plate 8 is subjected to thrust or tension, the spring 11 will be driven to deform, so that the spring 11 plays a certain supporting role for the fixing plate 8. When the fixing plate 8 loses resistance, it will be reset by the spring 11;

[0021] A threaded hole 13 is provided in the fixing groove 12, and the guide rod 7 is rotatably connected in the sealing ring 2. By providing the auxiliary block 3, when the positioning rod 10 is pulled, the positioning rod 10 will slide in the auxiliary block 3, so that the auxiliary block 3 plays a certain auxiliary role in the movement of the positioning rod 10, thereby preventing the positioning rod 10 from getting stuck when moving;

[0022] A bearing part 4 is provided in the bearing body 1, and two grooves 5 are provided outside the bearing body 1. Bolts 9 are provided in the fixing plate 8, and the fixing plate 8 is connected to the rotating plate 6 through the bolts 9. By setting a fixing groove 12, when the rotating plate 6 is rotated and clamped with the auxiliary block 3, the fixing plate 8 in the auxiliary block 3 will be clamped in the fixing groove 12, so that the fixing groove 12 plays a certain positioning role for the fixing plate 8, thereby avoiding misalignment of the rotating plate 6 and the auxiliary block 3.

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

[0024] When the tapered roller bearing is in use, the sealing ring 2 can be sleeved on the surface of the bearing body 1, and the sealing ring 2 will be clamped with the groove 5. When a thrust is applied to the rotating plate 6, it will rotate around the guide rod 7. During the rotation, the rotating plate 6 pulls the positioning rod 10, and the positioning rod 10 pulls the fixed plate 8 to slide in the auxiliary block 3. The fixed plate 8 will drive the spring 11 to deform when sliding. When the rotating plate 6 is clamped with the auxiliary block 3, the positioning rod 10 is released, and the fixed plate 8 is reset by the spring 11. The reset fixed plate 8 is clamped in the fixing groove 12, and the fixed plate 8 is connected to the threaded hole 13 through the bolt 9.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. 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.
