Description

Technical Field

[0001] This utility model relates to the technical field of rotary shaft sealing structures, and in particular to a rotary shaft sealing structure. Background Technology

[0002] A rotary shaft seal structure is primarily used in sealing devices within mechanical equipment, especially in applications where leakage of liquids or gases between the rotating shaft and the external environment is required. Rotary shaft seal structures are typically used to prevent leakage of liquids, gases, or solid particles between the rotating shaft and the stationary housing, achieving a better sealing effect, thereby extending the equipment's service life and improving operating efficiency. Mechanical seals are a common type of rotary shaft seal, mainly composed of a stationary ring and a rotating ring. The rotating ring is connected to the rotating shaft, while the stationary ring is fixed to the housing. A spring provides a certain contact pressure between the two, forming a sealing surface to prevent fluid leakage. Mechanical seals are suitable for high-pressure, high-temperature, or harsh working environments. They feature low friction loss, long service life, and high sealing performance.

[0003] However, the existing rotary shaft seal structure is cumbersome to install and disassemble, which increases time costs and workload, resulting in low maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary shaft sealing structure to solve the problem mentioned in the background art that the existing rotary shaft sealing structure is cumbersome to install and disassemble, which increases time costs and workload, resulting in low maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary shaft sealing structure, comprising a base, a sealing assembly fixedly connected to one side of the base, a sealing ring inserted into one side of the sealing assembly, an end cap fixedly connected to one side of the sealing ring, four sets of mounting components slidably connected in a circular array inside the end cap, a rotating shaft rotatably connected inside the base, a heat-resistant silicone sealing sleeve fitted onto the surface of the rotating shaft, the sealing assembly comprising a fixing ring fixedly connected to one side of the base, several sets of support springs fixedly connected in a circular array on the top surface of the fixing ring, and a compression ring fixedly connected to one end of each support spring; the mounting components comprising a sliding rod slidably connected in a circular array inside the end cap, a telescopic spring fitted onto one end of each sliding rod, and a locking block fixedly connected to one end of each sliding rod.

[0006] As a further embodiment of this utility model, one end of the sliding rod is inserted into a socket, and the other end of the sliding rod is fixedly connected to a knob. The knob is used to drive the sliding rod.

[0007] As a further embodiment of this utility model, the socket has a slot inside that matches the locking block. The socket is fitted onto the surface of the base, and the slot facilitates the locking of the locking block.

[0008] As a further embodiment of this utility model, a support plate is fixedly installed on one side of the base by bolts, and two sets of clamps are fitted onto the surface of the heat-resistant silicone sealing sleeve. The clamps serve to fix the heat-resistant silicone sealing sleeve.

[0009] As a further embodiment of this utility model, both ends of the two sets of clamps are provided with threaded holes, and threaded bolts pass through the inside of the threaded holes. The threaded bolts serve to install the clamps.

[0010] As a further embodiment of this utility model, two sets of moving rings are fitted onto the surfaces of both sides of the heat-resistant silicone sealing sleeve. Mounting holes are provided on both sides of the moving rings, and mounting bolts pass through the interior of the mounting holes. The mounting bolts serve to fix the moving rings.

[0011] As a further embodiment of this utility model, two sets of compression springs are fixedly connected to one side of the two sets of moving rings. The moving rings are made of carbon graphite material. The compression springs serve to support the moving rings.

[0012] This utility model provides a rotary shaft sealing structure, which has the following beneficial effects:

[0013] 1. This rotary shaft sealing structure, through the installation component, allows for convenient disassembly and reassembly of the end cover. Pressing the knob causes the knob to move the sliding rod within the sliding hole on the end cover. The telescopic spring contracts under pressure, disengaging the locking block at one end of the sliding rod from the slot in the socket. Rotating the sliding rod then pulls the locking block out of the socket, opening the end cover. For installation, align the sliding rod on the end cover with the socket, insert it, rotate the sliding rod, and release the knob. The telescopic spring then returns to its original deformation, pulling the sliding rod back into place, causing the locking block to engage with the slot. This achieves convenient end cover disassembly and reassembly, simplifying the process, significantly reducing operation time, and improving maintenance efficiency.

[0014] 2. This rotary shaft sealing structure, through the arrangement of the sealing components and sealing ring, allows the sealing ring to be inserted into the compression ring when the end cover is installed on the base. Since the fixing ring is fixed on one side of the base, the compression ring is pressed against the support spring. The support spring deforms under force, generating elastic force, which pushes the compression ring tightly against the sealing ring, thereby achieving the effect of sealing the gap between the end cover and the base. This prevents dust or dirt from entering the gap between the end cover and the base, which could cause structural damage and improve the service life of the rotary shaft sealing structure.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a rotary shaft sealing structure, including a base 1, with a sealing component 2 fixedly connected to one side of the base 1. Through the arrangement of the sealing component 2 and the sealing ring 3, the gap between the end cover 4 and the base 1 is sealed, preventing dust or dirt from entering the gap and causing structural damage, thus improving the service life of the rotary shaft sealing structure. A sealing ring 3 is inserted into one side of the sealing component 2, and an end cover 4 is fixedly connected to one side of the sealing ring 3. Four sets of mounting components 5 are slidably connected in a circular array inside the end cover 4. The mounting components 5 facilitate convenient assembly and disassembly of the end cover 4. The installation and disassembly process has been streamlined, significantly reducing operation time and improving maintenance efficiency. The base 1 is internally connected to a rotating shaft 6, and the surface of the rotating shaft 6 is fitted with a heat-resistant silicone sealing sleeve 7. The sealing assembly 2 includes a fixing ring 201 fixedly connected to one side of the base 1. The top surface of the fixing ring 201 is fixedly connected to several sets of support springs 202 in a ring array. One end of the support springs 202 is fixedly connected to a compression ring 203. The mounting assembly 5 includes a sliding rod 501 slidably connected to the inside of the end cover 4 in a ring array. One end of the sliding rod 501 is fitted with a telescopic spring 502, and one end of the sliding rod 501 is fixedly connected to a locking block 503.

[0023] One end of the sliding rod 501 is connected to a socket 8, and the other end of the sliding rod 501 is fixedly connected to a knob 9. The knob 9 is used to drive the sliding rod 501.

[0024] The socket 8 has a slot inside that matches the card block 503. The socket 8 is fitted onto the surface of the base 1. The slot facilitates the insertion of the card block 503.

[0025] A support plate 10 is fixedly installed on one side of the base 1 by bolts. Two sets of clamps 11 are fitted onto the surface of the heat-resistant silicone sealing sleeve 7. The clamps 11 are used to fix the heat-resistant silicone sealing sleeve 7.

[0026] Both ends of the two sets of clamps 11 are provided with threaded holes, and threaded bolts 12 pass through the inside of the threaded holes. The threaded bolts 12 serve to install the clamps 11.

[0027] Two sets of moving rings 13 are fitted onto the surfaces of both sides of the heat-resistant silicone sealing sleeve 7. Mounting holes are provided on both sides of the moving rings 13, and mounting bolts 14 pass through the interior of the mounting holes. The mounting bolts 14 serve to fix the moving rings 13.

[0028] Two sets of compression springs 15 are fixedly connected to one side of each of the two sets of moving rings 13. The moving rings 13 are made of carbon graphite. The compression springs 15 support the moving rings 13.

[0029] In this invention, the working steps of the device are as follows:

[0030] First step: When the end cap 4 is installed on the base 1, the end cap 4 drives the sealing ring 3 to insert into the compression ring 203. Since the fixing ring 201 is fixed on one side of the base 1, the compression ring 203 is pressed against the support spring 202. The support spring 202 deforms under force and generates elastic force, pushing the compression ring 203 tightly against the sealing ring 3 in the opposite direction.

[0031] Second step: When it is necessary to remove the end cover 4, press the knob 9 so that the knob 9 drives the sliding rod 501 to slide in the sliding hole on the end cover 4. The telescopic spring 502 is compressed by force, and then the locking block 503 at one end of the sliding rod 501 disengages from the slot in the socket 8. Rotate the sliding rod 501 so that the locking block 503 is pulled out from the socket 8, thereby opening the end cover 4.

[0032] Third step: When installation is required, align the sliding rod 501 on the end cover 4 with the socket 8 and insert it. Then rotate the sliding rod 501 and release the knob 9 so that the telescopic spring 502 pulls the sliding rod 501 to restore its deformation, and then the locking block 503 is locked into the slot.
