Drive shaft bearing for miniature cooling fan for electronic equipment has rotating bearing sector has a spherical surface minimizing in miniature cooling fan

摘要

A shaft rests within and rotates a slip bearing with an axial hole. The shaft (10) has an outer circumference with a rotating bearing sector (11) and a non-spherical sector (21). The rotating bearing sector has a spherical surface extending over more than half of the shaft circumference, and which holds the shaft when this rotates within the bearing (20) axial hole (21).
