sõrmusliitmik

Sõrmusliitmik refers to a type of mechanical fastener, commonly known in English as a split ring, snap ring, or circlip. It is a semi-flexible metal ring, typically made of spring steel, with open ends that allow it to be compressed or expanded for insertion into a groove on a shaft or inside a bore. Once fitted into its groove, the ring's spring action holds it securely in place.

There are two primary types of sõrmusliitmik: internal and external. Internal sõrmusliitmikud are designed to fit inside a bore or housing, retaining components on a shaft. They are typically installed by compressing the ring and inserting it into a circular groove. External sõrmusliitmikud are designed to fit onto a shaft, retaining components on the shaft. They are usually expanded and placed into a groove on the exterior of the shaft.

Sõrmusliitmikud are widely used in various mechanical applications, including automotive engines, transmissions, pumps, and industrial machinery, to prevent axial movement of components. They serve as cost-effective and reliable alternatives to more complex retaining systems like nuts and bolts or threaded fasteners in certain situations. Their compact design makes them suitable for applications where space is limited. The selection of the correct size and type of sõrmusliitmik is crucial for ensuring proper function and preventing component dislodgement.
