Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] Such as figure 1 As shown, a fan using an oil-impregnated bearing includes a casing 1, an oil-impregnated bearing, a sealing oil cover 2, a stator 3, and a rotor 4 that can rotate relative to the stator. The casing 1 includes a shaft seat 8, and the stator 3 is set on the shaft seat 8 Peripherally, the oil bearing is accommodated in the shaft seat 8, the oil seal cover 2 is located at the bottom of the oil bearing, and the lubricating fluid in the oil bearin...

Abstract

The invention provides a fan provided with an oil bearing. The fan provided with the oil bearing comprises a casing, the oil bearing, a sealing oil cover, a stator and a rotator which can rotate relative to the stator; the casing comprises a shaft seat; the stator is sleeved to the periphery of the shaft seat; the oil bearing is accommodated inside the shaft seat; the sealing oil cover is arranged at the bottom of the oil bearing; lubricating fluid inside the oil bearing is sealed inside the shaft base; the rotator comprises a hub, fan blades and a rotating shaft which is arranged inside the oil bearing and can rotate relative to the oil bearing; the hub is arranged on the periphery of the stator; the fan blades are arranged on the periphery of the hub in a ring mode; the rotating shaft vertically extends towards the shaft base from the hub center; a plurality of sinking grooves are formed in the bottom of the outer circumference of the oil bearing. The fan provided with the oil bearing has the advantages of prolonging the service life due to the facts that part of spare lubricating oil is stored inside the sinking grooves which are formed in the bottom of the outer circumference of the oil bearing and the spare lubricating oil is automatically supplied when immersion oil precipitation inside the oil bearing is deficient.

Description

technical field [0001] The invention relates to a fan, in particular to a fan using an oil-impregnated bearing. Background technique [0002] The fan is a key component of the computer cooling system. Improving the operating life and reliability of the fan is very important to ensure the stable operation of the computer system. The bearing lubrication of the fan plays a decisive role in improving the service life of the fan and reducing noise. [0003] Most of the existing fans use ball bearings or oil-impregnated bearings, wherein ball bearings belong to rolling friction. This design has a small friction coefficient and a relatively high speed, so it can bring better heat dissipation effect, but the disadvantage is that the price is higher; the oil-impregnated bearing belongs to sliding friction, and the noise is small. By absorbing and conserving lubricating oil, it reduces wear, but with The falling dust and volatilization of the oil will increase the noise of the beari...
