Fan motor
First Claim
1. An apparatus for a fan motor comprising:
- a base;
a cylindrically-shaped bearing housing integrally formed from the base;
a pair of bearings set in an interior of the bearing housing;
a rotational shaft supported by the pair of bearings;
a shield part integrally formed on the bearing housing at an end opposite the base and which extends in a radial direction towards the rotational shaft; and
a retainer cap set through an aperture in the base.

Abstract
An apparatus to render the shield of a bail bearing unnecessary and to improve the lubricity inside a fan motor is presented. A bearing housing is integrally formed with a base of the fan motor, and a shield part is formed at one end of the bearing housing. A ball bearing, spacer and sleeve bearing are set inside from the other end of the bearing housing, and these are fixed in place by pressing in a retainer cap. The interior of the bearing housing is then shielded at each end by the shield part and the retainer cap, making the need for a shielded ball bearing unnecessary. A rotational shaft, to which a rotor and impeller are attached, is supported by the ball bearing and the sleeve bearing. Inside the bearing housing, lubricating oil passes back and forth between the ball bearing and sleeve bearing, thereby enabling the elimination of insufficiencies in lubricating oil, and improving lubricity.

17. An apparatus for a fan motor, comprising:
-
a bearing housing, having a hollow interior and a first and a second open end;
a shield part integrally formed on the first end of the bearing housing and which extends towards the interior of the bearing housing; and
a retainer cap that fits onto the second end of the bearing housing, wherein the interior of the bearing housing is thus shielded by the shield part and the retainer cap. - View Dependent Claims (18, 19, 20)
