Latest Patents

Juhani Kuusela's latest patents include cutting-edge designs for slide ring seals. The first patent describes a slide ring seal specifically designed for sealing a shaft that rotates with respect to a wall. This invention features a body portion along with seal rings equipped with slide rings, arranged in such a way that maintains the sealing slide faces pressed against each other while allowing them to rotate. Each slide ring is securely fastened in its respective seal ring using a shrink fit, ensuring that the pressure acts precisely on the centroid of the slide ring's cross-sectional area. The design also incorporates a convex surface on at least one engaging face to maintain optimal force application.

The second patent introduces another slide ring seal with unique characteristics aimed at improving wearability and sealing effectiveness. In this invention, the seal ring consists of two ring portions that are fastened together through a radial shrinkage fit. The slide ring is designed in an L-shape cross-section with multiple supporting surfaces, ensuring a robust connection between the slide ring and seal ring. A radial clearance is maintained to enhance the operational capacity of the seal assembly.
