関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hermetic compressor, and particularly to a hermetic compressor suitable for collecting ferrous and non-ferrous foreign substances mixed in refrigerating machine oil.

石の厚みより小なる間隙を形成したものである。The conventional hermetic compressor of this type is
As shown in Publication No. 3, a magnet is fitted and attached to a pin protruding from at least one of the lower end surface of the compressor pump part or the inner bottom of the sealed case, and the tip of the pin and the inner bottom of the sealed case or the inner bottom of the sealed case are fitted. A gap smaller than the thickness of the magnet is formed between the magnet and the lower end surface of the compressor pump section.

あった。The above-mentioned conventional technology can attract ferrous foreign matter such as welding spatter and wear powder around the magnet, but it also attracts ferrous foreign matter such as welding spatter and abrasion powder around the magnet, as well as ferrous foreign matter that is not close to the magnet, grinding wheel powder, casting sand, and oxide scale that are mixed in the refrigerating machine oil. It was difficult to capture non-ferrous foreign substances such as

る。When refrigerating machine oil passes through the inner hole of the rotating shaft of a hermetic compressor,
Since the centrifugal force is applied as the rotating shaft rotates, foreign matter in the refrigerating machine oil moves into the blind hole perpendicular to the inner hole of the rotating shaft and is captured.

ーン７は往復運動する。FIG. 1 is a longitudinal cross-sectional view of a hermetic compressor showing an embodiment of the present invention, FIG. 2 is a cross-sectional view of the main part thereof, and FIG. 3 is an enlarged cross-sectional view of the main part shown in FIG. 2. In the figure, an electric part and a pump part are arranged inside a closed container 1. The electric part is composed of a stator 2 and a rotor 2', and the pump part is composed of a main bearing 3, a rotating shaft 4, a cylinder 5, a roller 6, a vane 7, a sub-bearing 14, and the like. The status is fixed to the closed container 1 by shrink fitting or the like, and the main bearing 3 is fixed to the closed container 1 by welding or the like. The rotor 2' is fixed to the rotating shaft 4 by press fitting or the like. The vane 7 is pressed against the roller 6 by a spring 16. As the rotating shaft 4 rotates, the roller 6 rotates eccentrically, and the vane 7 reciprocates.

の如く給油管１１を通り。This eccentric rotation of the rotor 6 performs suction, compression, and discharge pumping actions. Also, due to the reciprocating movement of the vane 7 and the difference in resistance between both ends of the oil supply piece 8, the refrigerating machine oil 15 passes through the oil supply pipe 11 as shown by the arrow.
回転軸４の中空内孔部１２に供給される。It is supplied to the hollow inner hole 12 of the rotating shaft 4.

凍機油中に戻る確率は非常に少ない。また比重の大きい
鉄系異物を効率的に捕捉することかできる。A hole, for example, a blind hole 9, perpendicular to the hollow inner hole 12 is bored in the eccentric part of the rotating shaft 4, and foreign matter 13 in the refrigerating machine oil is caught in the blind hole 9 by centrifugal force, and is further trapped inside the blind hole 9. There is a very low probability that foreign matter that has passed through the cylindrical piece 10 will return to the circulating refrigerating machine oil. In addition, it is possible to efficiently capture iron-based foreign substances with high specific gravity.

確率を低減し、信頼性を向上させるという効果を奏す。According to the present invention, it is possible to capture ferrous and non-ferrous foreign substances contained in the refrigerating machine oil supplied to the sliding parts, and to prevent the sliding surface from getting stuck due to foreign substances entering the sliding parts. This has the effect of reducing the probability of damage such as wear and improving reliability.
