The mounting ring of the multi-model automatic matching floating oil seal can automatically match the installation ring. CONTENT OF THE INVENTION
[0004] The application aims to solve the problems of the existing mounting ring of the floating oil seal, such as low matching efficiency, easy sliding and loosening during the installation of the floating oil seal, and weakened overall sealing efficiency, and provides the mounting ring of the multi-model automatic matching floating oil seal.
[0005] The technical scheme adopted by the application is as follows: the mounting ring of the multi-model automatic matching floating oil seal, the surface of the floating seal seat is movably mounted with a shape ring, the surface of the shape ring is provided with a mounting groove, and the surface of the mounting groove is movably inserted with a matching ring.
[0006] By adopting the above technical scheme, the mounting ring can float along with the slight displacement of the component during the operation of the equipment, and always keeps a close contact state, so that the sealing effect is ensured. The device is provided with the matching ring in the shape ring, the matching ring can automatically stretch and shrink to adapt to the installation conditions of different sizes. In the non-installation case, the matching ring can adapt to the size of the floating oil seal. The floating oil seal has a certain elasticity, and can adapt to different sizes during the installation process to achieve the sealing effect. The mounting ring is made of silica gel material and has strong plasticity and can stretch and shrink. During the installation process, the mounting ring can adapt to different sizes to adapt to the slight displacement and deformation of the equipment, so that the sealing effect is maintained. The floating oil seal can automatically adjust the position during the operation of the equipment, reduce leakage, and improve the overall performance of the equipment. The shape ring has good wear resistance and will not be easily worn. The shape ring generates a pressing force on the sealing end surface of the floating ring through the deformation after being compressed in the axial direction, so as to prevent external dust, water and sludge from entering and protect the internal lubricating grease from leaking.
[0007] In a preferred embodiment, the surface of the floating seal seat is provided with a floating seal ring adjacent to the shape ring.
[0008] By adopting the technical scheme, the tapered gap inside the contact surface of the floating seal ring is beneficial to the entry of lubricating oil into the sealing surface, and through the centrifugal action during rotation, the capillary suction force and the effect of increased internal pressure after temperature rise in the sealing cavity, a very thin oil film is formed to realize lubrication, cooling and avoid excessive wear of the end surface. In addition, the design of the floating oil seal makes the bright band on the sealing surface slowly move inward, and the stored elastic energy is released during operation to achieve axial compensation, thereby prolonging the service life.
[0009] In a preferred embodiment, a connecting portion is fixedly installed on the surface of the floating seal seat.
[0010] By adopting the technical scheme, the floating oil seal is composed of two floating seal rings and two rubber rings, and industrial adhesive is bonded to the connecting portion to bond the two floating seal seats and install the floating oil seal as a whole.

[0012] By adopting the technical scheme, the L-shaped fixing plate can connect the floating seal seat and the floating seal ring, the spring has a certain elastic force, and the L-shaped fixing plate and the floating seal ring can be tightly connected, thereby achieving the connection of the floating seal seat and the floating seal ring. The tight connection of the floating seal seat and the sealing ring can effectively reduce the leakage of the medium and ensure the sealing effect. Through reasonable structural design, such as multiple sealing technology and strong oil film tension, the leakage of the sealing medium can be effectively prevented, the stable operation of the system can be ensured, the tight connection can ensure that the gap between the sealing ring and the floating seal seat is minimized, thereby forming a stable oil film and reducing friction.
[0013] In a preferred embodiment, an L-shaped fixing plate is fixedly installed at the end of the spring.
[0014] By adopting the technical scheme, the tight engagement connection of the floating seal seat and the sealing ring can ensure the sealing effect and prevent the leakage of the medium. This connection mode ensures the tight cooperation between the sealing ring and the floating seal seat through physical engagement, thereby effectively preventing the leakage of the medium. The tight engagement connection enables the sealing system to remain stable under various working conditions and is not easily affected by external interference, thereby ensuring the long-term stable operation of the equipment.
[0015] In a preferred embodiment, the size of the L-shaped fixing plate matches the size of the limiting groove.
[0016] By adopting the technical scheme, a magnetic attraction device is installed in the limiting groove, and the L-shaped fixing plate also adopts a magnetic attraction structure. When the floating oil seal is maintained, the L-shaped fixing plate can be pulled at the limiting groove to observe and replace the matching ring, thereby ensuring good sealing performance of the floating oil seal.
[0017] Therefore, by means of the technical scheme, the application has the following beneficial effects:
[0018] In the application, the installation ring can float with the slight displacement of the component during the operation of the equipment, and always maintains the adhering state, thereby ensuring the sealing effect. The matching ring is installed in the O-shaped ring, and can automatically expand or contract to adapt to the installation conditions of different sizes. In the non-installation condition, the matching ring can adapt to the size of the floating oil seal. The floating oil seal has a certain elastic force, and can adapt to different sizes during the installation process to achieve the sealing effect. The installation ring itself is made of silica gel material, has strong plasticity, and can expand or contract. During the installation process, it can adapt to different sizes to adapt to the slight displacement and deformation of the equipment, thereby maintaining the sealing effect. It can automatically adjust the position during the operation of the equipment, reduce the leakage, and improve the overall performance of the equipment. The O-shaped ring has good wear resistance and will not be easily worn. The O-shaped ring generates a pressing force on the sealing end surface of the floating ring through the deformation after being compressed in the axial direction, thereby preventing the entry of external dust, water, sludge and the like, and protecting the internal lubricating grease from leaking.
[0019] The tapered gap inside the contact surface of the floating seal ring is beneficial to the entry of lubricating oil into the sealing surface. Through the centrifugal effect during rotation, the capillary suction effect and the effect of increased internal pressure after temperature rise in the sealing cavity, a very thin oil film is formed to realize lubrication, cooling and avoid excessive wear of the end surface. In addition, the design of the floating oil seal makes the bright band line on the sealing surface slowly move inward, and the stored elastic energy is released during the operation process, thereby playing an axial compensation role and prolonging the service life.

[0028] The installation ring can float along with the slight displacement of the component during the operation of the equipment, and always maintains the adhering state, thereby ensuring the sealing effect. The matching ring 6 in the O-shaped ring 2 can automatically stretch and shrink to adapt to the installation conditions of different sizes. In the non-installation condition, the matching ring 6 can adapt to the size of the floating oil seal. The floating oil seal has a certain elastic force, which can adapt to different sizes during the installation process to achieve the sealing effect. The installation ring itself is made of silica gel material, has strong plasticity, and can stretch and shrink. During the installation process, it can adapt to different sizes to adapt to the slight displacement and deformation of the equipment, thereby maintaining the sealing effect. It can automatically adjust the position during the operation of the equipment, reduce leakage, and improve the overall performance of the equipment. The O-shaped ring 2 has good wear resistance and will not be easily worn. The O-shaped ring 2 generates a pressing force on the sealing end surface of the floating ring through the deformation after being compressed in the axial direction, thereby preventing external dust, water, sludge, and the like from entering and protecting the internal lubricating grease from leaking.
[0029] The floating seal ring 4 is arranged at the adjacent position between the surface of the floating seal seat 1 and the O-shaped ring 2. The tapered gap in the contact surface of the floating seal ring 4 is beneficial to the entry of lubricating oil into the sealing surface. Through the centrifugal action during rotation, the capillary suction force, and the effect of the increase in internal pressure after the temperature rise in the sealing cavity, a very thin oil film is formed to realize lubrication, cooling, and avoid excessive wear of the end surface. In addition, the design of the floating oil seal makes the bright band on the sealing surface slowly move inward, the stored elastic energy is released during the operation process, thereby playing an axial compensation role to prolong the service life.
[0030] The connecting portion 3 is fixedly installed on the surface of the floating seal seat 1. The floating oil seal is composed of two floating seal rings and two rubber rings. The connecting portion is bonded with industrial adhesive, which can bond the two floating seal seats 1 and install the whole floating oil seal.
[0031] The surface of the floating seal seat 1 is provided with a limiting groove 8, and the surface of the limiting groove 8 is bonded with a spring 9. The L-shaped fixing plate 7 can be connected with the floating seal seat 1 and the floating seal ring 4, and the spring 9 has a certain elastic force, which can tightly connect the L-shaped fixing plate 7 with the floating seal ring 4, thereby achieving the connection effect of the floating seal seat 1 and the floating seal ring 4. The tight connection of the floating seal seat and the seal ring can effectively reduce the leakage of the medium and ensure the sealing effect. Through reasonable structure design, such as multiple sealing technology and strong oil film tension, the leakage of the sealing medium can be effectively prevented, the stable operation of the system can be ensured, the tight connection can ensure that the gap between the seal ring and the floating seal seat is minimized, thereby forming a stable oil film and reducing friction.
[0032] The end of the spring 9 is fixedly provided with the L-shaped fixing plate 7. The tight interlocking connection of the floating seal seat and the seal ring can ensure the sealing effect and prevent the leakage of the medium. This connection mode ensures the tight cooperation between the seal ring and the floating seal seat through physical interlocking, thereby effectively preventing the leakage of the medium. The tight interlocking connection enables the sealing system to maintain stability under various working conditions and is not easily disturbed by the outside world, thereby ensuring the long-term stable operation of the equipment.
[0033] The size of the L-shaped fixing plate 7 matches the size of the limiting groove 8. The limiting groove 8 is provided with a magnetic attraction device, and the L-shaped fixing plate 7 also adopts a magnetic attraction structure. When the floating oil seal is maintained, the L-shaped fixing plate 7 at the limiting groove 8 can be pulled to observe and replace the matching ring 6, thereby ensuring good sealing performance of the floating oil seal.
[0034] The implementation principle of the installation ring of the multi-model automatic matching floating oil seal embodiment of the application is as follows:
[0035] The installation ring can float along with the slight displacement of the component during the operation of the equipment through the structure design, and always maintains the adhering state, thereby ensuring the sealing effect. The device is provided with the matching ring 6 in the 0-shaped ring 2. The matching ring 6 can automatically stretch and shrink to adapt to the installation conditions of different sizes. In the non-installation condition, the matching ring 6 can adapt to the size of the floating oil seal. The floating oil seal has a certain elastic force, which can adapt to different sizes during the installation process, thereby achieving the sealing effect. The installation ring itself is made of silica gel material, has strong plasticity, and can stretch and shrink. During the installation process, it can adapt to different sizes to adapt to the slight displacement and deformation of the equipment, thereby maintaining the sealing effect. The device can automatically adjust the position during the operation of the equipment, reduce the leakage, and improve the overall performance of the equipment. The 0-shaped ring 2 has good wear resistance and will not be easily worn. The 0-shaped ring 2 generates a pressing force on the floating ring sealing end face through the deformation after being compressed in the axial direction, thereby preventing the entry of external dust, water, sludge and the like, and protecting the internal lubricating grease from leaking.
[0036] The tapered gap inside the contact surface of the floating seal ring 4 facilitates the entry of lubricating oil into the sealing surface. Through the effects of centrifugal force during rotation, capillary suction, and increased internal pressure due to temperature rise in the sealing cavity, a very thin oil film is formed, achieving lubrication, cooling, and preventing excessive wear of the end surface. In addition, the design of the floating oil seal causes the bright band on the sealing surface to slowly move inward, releasing the stored elastic energy during operation, which serves as axial compensation, thereby extending the service life.
[0037] The L-shaped fixing plate 7 can connect the floating seal seat 1 and the floating seal ring 4. The spring 9 has a certain elastic force, which can tightly connect the L-shaped fixing plate 7 and the floating seal ring 4, thereby achieving the connection of the floating seal seat 1 and the floating seal ring 4. The tight connection between the floating seal seat and the sealing ring can effectively reduce medium leakage and ensure sealing effect. Through reasonable structural design, such as multiple sealing technology and strong oil film tension, leakage of sealing medium can be effectively prevented, ensuring stable operation of the system. The tight connection can ensure that the gap between the sealing ring and the floating seal seat is minimized, thereby forming a stable oil film and reducing friction.
