Abstract

PURPOSE:To reduce an amount of lubricating oil flowing out from a delivery pipe and prevent seizure of a slide part by a method wherein a centrifugal separating plate is mounted on a shaft positioned between a motor in a closed casing and the upper bearing of a machine part. CONSTITUTION:A centrifugal separating plate 24 is positioned between a motor 2 and an upper bearing 4 and secured on a shaft 9. Oil finishing lubrication of a slide part between a lower bearing 3 and the upper bearing 4 and blown out through a gap between the upper shaft 4 and the shaft 9 is collided with the centrifugal plate 24. The oil is flied in the direction of an outer periphery and flows downward along the wall of a closed casing 1, resulting in reduction of an amount of oil flowing out from a delivery pipe 17 and the possibility to prevent seizure of a slide part.

Problem to be Solved by the Invention However, in the above configuration, the lower bearing 3. After lubricating the sliding parts of the upper bearing 4, the oil blown out from the gap between the upper bearing 4 and the shaft 9 hits the balance weight 23 of the rotor 21 and is stirred into a mist, which flows through the discharge hole of the discharge cover 8. The problem is that the oil mixes with the refrigerant discharged from the refrigerant 8a and flows out from the discharge pipe 17 into the refrigeration cycle, causing oil depletion and seizing of the sliding parts.

According to the above-described structure, the present invention has the above-mentioned configuration, so that when the sliding parts of the lower bearing and the upper bearing have been lubricated, the oil blown out from the upper part of the gap between the upper bearing and the shaft hits the centrifugal separator plate and scatters toward the outer periphery of the sealed casing wall. Since the oil flows downward along the rotor, the balance weight of the rotor increases the agitation, reduces oil leakage from the discharge pipe, and prevents seizure of the sliding parts.

According to this embodiment, after the sliding parts of the lower bearing and the two bearings have been lubricated, the oil blown out from the upper part of the gap between the upper bearing and the shaft hits the centrifugal plate and flies toward the outer circumference, and flows along the wall of the sealed casing. Since the oil flows downward, the amount of oil flowing out from the discharge pipe is reduced, and seizure of the sliding parts can be prevented.

After the sliding parts of the lower bearing and upper bearing have been lubricated, the oil that blows out from the upper part of the gap between the upper bearing and the shaft hits the centrifugal separation plate, flies toward the outer periphery, and flows down along the wall of the sealed casing, causing oil to flow out from the discharge pipe. Oil spillage is reduced and sliding parts can be prevented from burning out.
