摘要： The invention relates to an oil-leak proof bearing system, and the system includes a bearing, an oil-leak proof cover and a rotor shaft. The center portion of the oil-leak proof cover defines a through hole, and the inner wall defining the through hole is provided with at least one first guiding groove thereon extended obliquely downward from the upper edge of the inner side face to force oil dispersed by the rotor shaft to flow back into the bearing system. The bottom surface of the oil-leak proof cover, contacting the bearing, is provided with second guiding grooves extending radially approximately from the center thereof. The capillarity of the second guiding grooves guides the oil dispersed by the rotor shaft to flow radially. The design of the first and second guiding grooves prevents the bearing system from leakage of lubricating oil, and provides a closed oil loop for operation.

摘要： A fan housing and a fan have stationary blades for guiding airflow. Each stationary blade has at least one airflow-guiding element extending therefrom along the circumference of the fan. The side wall of the airflow-guiding element changes the direction of the airflow so that the airflow at the outlet is fully introduced toward the heat source. Furthermore, the airflow-guiding element regulates the airflow, restrains the turbulent flow at the outlet and on the curved surface of the stationary blade, decreases the noise arising from the turbulent flow, and prevents foreign matter from entering the fan housing so as to protect the inside elements thereof.

摘要： A motor. The motor includes a stator, a rotor, a top magnetic structure, and a bottom magnetic structure. The stator is disposed in a frame. The rotor is also disposed in the frame, corresponding to the stator. The rotor comprises a shaft, extended axially from the rotor. The shaft does not contact the stator or the frame. The bottom magnetic structure is at the bottom of the frame. The top magnetic structure is on the top of the frame. The top and bottom magnetic structures are opposite to each other in an axial direction. Magnetic attraction generated between the first magnetic structure and the second magnetic structure attracts and positions the shaft therebetween such that the first magnetic structure, the second magnetic structure, and the shaft are coaxially aligned.
