Fan bearing fixing anti-slip structure

Abstract

A fan bearing fixing and anti-slip structure includes a fan frame, a shaft core, two bearings, and a first spring. The fan frame has a base with a protruding bearing sleeve on the air outlet side; the shaft core is disposed within the bearing sleeve; the two bearings are respectively installed within the bearing sleeve and mounted on the shaft core, each bearing including an inner ring that mates with the shaft core and an outer ring that mates with the bearing sleeve; the first spring is sleeved on the shaft core and located between the inner rings of the two bearings, generating an axial force for elastic support between the two inner rings, fixing the two inner rings in a predetermined position, thereby limiting radial relative sliding between the inner rings of the two bearings and the shaft core, improving the stability of the two bearings and extending their service life.
