Abstract: The invention relates to an oil-suspending and oil-retaining bearing. The bearing has a bore for the spindle of the rotor to penetrate therein. The periphery of at least one end penetrated by the bore is disposed a slotted ring inserted with the absorbent material beforehand. The end of the bearing has a plurality of guiding slots and the periphery of the bearing also has a plurality of guiding slots. Therefore, when lubricating oil seeps and diffuses due to the agitation of the spindle, the rising lubricating oil is collected by the guiding slots and guided into the slotted ring. In addition to blocking and suspending lubricating oil, the absorbent material in the slotted ring not only absorbs and store lubricating oil, but also provides the bearing the timely reuse and circulation of lubricating oil, effectively avoiding the drainage of lubricating oil and prolonging the life cycle of motor.

Abstract: The invention relates to an indirect power-linking device, which are disposed respectively the magnets at the locations where correspond to a power-driving device and a power-driven device that mutually attract. The magnets shall have at least one N pole and one pole. Therefore, when the power-driving device rotates, the magnetic field lines between the magnets of the power-driving device and the power-driven device are distorted to generate a suppressive effect in formation of a rotational torque. The rotational torque can drive the power-driven device and the power-driving device to generate a synchronous and powerful operation.

Abstract: The invention relates to a motor oil leakage protection structure, which includes a shaft tube. The inner wall of the shaft tube is formed at least two cascaded holes with different inner diameters. The hole with smaller inner diameter is disposed a bearing, and the hole with larger inner diameter is disposed a locating ring. Furthermore, the locating ring can isolate the top edge of the gap between the hole with smaller inner diameter and the bearing, and therefore, when the lubricating oil flows along the oil path formed by the gap and keeps rising up, due to the obstruction posed on the oil path, the rising speed of the lubricating oil is lessened so that the lubricating oil can be further absorbed and utilized repeatedly by the bearing to effectively avoid the drainage of the lubricating oil.

Abstract: This invention relates to an oil retaining structure of a spindle, wherein the outer peripheral surface of the spindle is provided with a first oil groove extending spirally along a clockwise direction and a second oil groove extending spirally along a counterclockwise direction. The first oil groove and the second oil groove across each other so as to form a plurality of collecting points. In operation, the oil film formed on the outer peripheral surface of the spindle will collect in the two oil grooves slowly, and the lubricating oil in the two oil grooves will bump into each other at the collecting points and then diffuse. As a result, an interior cycle is formed, which not only prevents the leaking of the lubricating oil but also makes the lubricating oil distribute evenly on the surface of the spindle.
