What is a damped laptop spindle?

A damped laptop spindle is simply a connecting element between a component that needs to rotate and a substrate. It includes a laptop spindle and a laptop sleeve, wherein a polygonal elastic sleeve is set between the annular gaps where the spindle and sleeve are connected, and is provided with an open groove along the axial direction, and is a wear-resistant part made of an elastic metal material. It is also possible to provide a coaxial arcuate surface that projects outward in both axial directions in the center part of the prismatic surface of the polygonal elastic sleeve.
