Introduction
The labyrinth seal is an important part of a bearing box and can effectively prevent bearing box from dust, liquid and gas intrusion. Labyrinth seal also called airtight seal, because of its unique structure and sealing effect, is widely used in automobile and machinery fields. Labyrinth seal applied on bearing box is called bearing box floating type labyrinth seal, which has the advantage of floating elastically in the bearing box.
Operation Principle
The working principle of bearing box floating type labyrinth seal is using the mechanical structure of the labyrinth sealing occasion. The axial clearance of the bearing box outer ring determines the position and size of the labyrinth seal. The construction of the labyrinth seal is exactly the opposite of the smooth bore seal, so that the pressure of the media on the same side of the labyrinth seal will produce corresponding force, thus shouldering the sealing pressure of bearing box. This type of labyrinth seal is not only suitable for high-speed and high-speed rotating parts, but also can be applied to static and low-speed rotating parts.
Features
The bearing box floating type labyrinth seal has a lot of advantages comparing with traditional bushing bearing seal. Firstly, it has a high degree of sealing. The combination of axial clearance and floating seal effectively form a multi-edge dynamic sealing structure, thus it has a better sealing effect than the traditional bushing seal. Secondly, it is easy to assemble and has a simple structure. The axis clearance of the bearing box outer ring determines the position and size of the labyrinth seal, so it is easy to assemble and release, thus greatly reducing the assembly cost. Thirdly, it has excellent floating capability. Its unique floating design can protect the bearing box environment in a full range, making it is suitable for long time lubricating and maintaining work.
Application areas
Due to its excellent sealing performance and assembly convenience, the bearing box floating type labyrinth seal has a wide application range, such as automobile, agricultural machinery and other related fields. For example, it can be used in ball bearings and rod end bearings, and it can also be used in the sealing of pipe flanges, as well as the sealing of rotating parts.
Conclusion
In conclusion, bearing box floating type labyrinth seal has excellent sealing performance and assembly convenience, which makes it be widely used in automotive, agricultural machinery and other fields. Its unique design can protect bearing box environment in a full range, making it the ideal sealing product for long term lubrication and maintenance work.
