Abstract

The invention provides a fan device with an oil bearing. The fan device comprises a base and the oil bearing, wherein the base is provided with a middle pipe and a shaft barrel extending from the middle pipe to one side; a bearing hole is formed in the shaft barrel; at least one butt joint portion is arranged in the position, opposite to the bearing hole, of the middle pipe; the oil bearing is provided with at least one assembling-connecting portion assembled on the butt joint portion. Therefore, the oil bearing is fixedly arranged in the bearing hole through mutual assembly of the assembling-connecting portions and the butt joint portions, and the situation that operation is affected by close-fitting interference and difficult control over dispensing can be avoided.

Description

technical field [0001] The invention relates to a fan device of an oil-impregnated bearing, in particular to an oil-impregnated bearing fan device which can effectively fix the oil-impregnated bearing and can avoid affecting operation due to interference tight fitting and uncontrollable glue dispensing. Background technique [0002] Press, the use of electronic information products (such as: computers, etc.) is becoming more and more popular and more widely used. Due to the rapid development of electronic information industry technology driven by demand, electronic information is developing towards the trend of increasing computing speed and increasing access capacity. The parts and components in the aforementioned electronic information products are often accompanied by high temperature during high-speed operation. [0003] Taking a computer mainframe as an example, the heat generated by its internal central processing unit (CPU) accounts for the majority. In addition, when...
