Abstract

A fan using a fluid bearing comprises a fan frame, a support member disposed in the middle of the fan frame, a stator assembly and a rotor assembly disposed in the periphery of the support member. The support member being a single structure includes an axle hole. The rotor assembly comprises a rotation shaft held in the axle hole and a magnet opposite to the stator assembly. The lubricating fluid held between the support member and the rotation shaft.

Description

【Technical field】 [0001] The invention relates to a fan, in particular to a fan using a fluid bearing. 【Background technique】 [0002] At this stage, fluid bearing devices have been increasingly applied to fan motors to reduce the wear of the main shaft, prolong the service life of the motor, and reduce the noise during rotation. [0003] like figure 1 Shown is a fluid bearing device of a conventional fan. The motor of the fan includes a sleeve 81, a main shaft 80 located in the sleeve 81 and having a certain gap with the sleeve 81, and lubricating fluid is stored in the gap to provide Medium of fluid pressure. When there is a certain relative speed between the main shaft 80 and the sleeve 81, the lubricating fluid around the main shaft 80 generates pressure to continuously push the main shaft 80, so that the main shaft 80 does not contact the sleeve 81 in the radial direction during the rotation, and avoids wear and noise generation. In order to obtain a better pressure...
