本発明は二重反転プロペラで推進する船舶用のプロペラ
軸軸受装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in propeller shaft bearing devices for ships propelled by counter-rotating propellers.
第1図は、従来の二重反転プロペラ装置の軸受の構成例
を示すものである。FIG. 1 shows an example of the configuration of a bearing in a conventional counter-rotating propeller device.
同図で、01は内軸、02は外軸、03は船体。In the same figure, 01 is the inner shaft, 02 is the outer shaft, and 03 is the hull.
04I″i内軸に固定の船尾側プロペラ、05は外軸に
固定の船首側プロペラ、06は外軸の内周面に固定の内
軸支持用すべり軸受、07は船体に固定の外軸支持用す
べり軸受、08はシール装置、矢印Aは内袖のlす1転
方向、矢印11. it:外軸の回転方向をそれぞわ示
す。04I''i Stern side propeller fixed to the inner shaft, 05 is the bow side propeller fixed to the outer shaft, 06 is a sliding bearing for supporting the inner shaft fixed to the inner peripheral surface of the outer shaft, 07 is an outer shaft support fixed to the hull 08 indicates the sealing device, arrow A indicates the direction of rotation of the inner sleeve, and arrow 11.it indicates the direction of rotation of the outer shaft.
内軸01は、外軸02の内周面に固定のすべり軸受06
で支持され、外軸02は、船体08に固定のすべり軸受
07で支持さJする。The inner shaft 01 has a sliding bearing 06 fixed to the inner peripheral surface of the outer shaft 02.
The outer shaft 02 is supported by a sliding bearing 07 fixed to the hull 08.
このとき、内11ilb o lは矢印式で示す回転方
向1(又は逆)、1AIl!1l102は矢印Bで示す
回転方向(又は逆)に図示しない主機により同同転数で
逆方向の回転が与えられる。At this time, 11ilb o l is the rotation direction 1 (or the opposite) indicated by the arrow type, 1AIl! 11102 is rotated in the opposite direction at the same rotation speed by a main engine (not shown) in the direction of rotation shown by arrow B (or in the opposite direction).
しかし9以上に述べた従来の二重反転プロペラの軸受装
置には9次の致命的な欠点がある。However, the conventional counter-rotating propeller bearing device described above has the ninth fatal drawback.
すなわち、内軸01を支持するすべり軸受06が外軸0
2の内周面に固定さJl、外軸02が内軸01と同回転
で逆向きに回る場合、内軸01と内袖すべり軸受06と
の摺動部には油膜は理論的に発生1〜得す、軸受として
の用を成さないということである。この場合の解決策と
して軸受の形状および油溝の形状を工夫すること等か考
えられるが。In other words, the sliding bearing 06 supporting the inner shaft 01 supports the outer shaft 0.
If the outer shaft 02 is fixed to the inner circumferential surface of the inner shaft 01 and rotates in the same direction as the inner shaft 01, an oil film will theoretically occur on the sliding part between the inner shaft 01 and the inner sleeve sliding bearing 06. -The advantage is that it is of no use as a bearing. A possible solution to this case would be to modify the shape of the bearing and the shape of the oil groove.
これとて根本的な解決策には成り得ない。This cannot be a fundamental solution.
そこで従来の船舶用二重反転プロペラ装置の軸受の欠点
を解消し、内軸支持軸受に負荷能力を持たせ軸系全体と
しての信頼性向上のために内軸支持軸受にころがり軸受
を採用することをシー
想)11シた。ころがり軸受の場合は、すべり軸受の場
合に油膜形成が不可となる同回転数、逆回転の条件は軸
受としての負荷能力を保有するに問題にはならない。す
なわち2本発明の船舶用二重反転プロペラ装置の軸受で
内軸の支持は。Therefore, we adopted a rolling bearing for the inner shaft support bearing in order to eliminate the drawbacks of the bearings of conventional counter-rotating propeller units for ships, give the inner shaft support bearing a load capacity, and improve the reliability of the shaft system as a whole. (I thought) 11 times. In the case of a rolling bearing, the conditions of the same rotation speed and opposite rotation, which would prevent oil film formation in the case of a sliding bearing, do not pose a problem in maintaining the load capacity of the bearing. In other words, the inner shaft is supported by the bearing of the contra-rotating propeller device for ships according to the present invention.

面により本発明の船舶用二重反転プロペラ装置の軸受に
ついて説明すると、第2図は本発明の装置の一実施例を
示す図であって。The rolling bearing fixed to the inner peripheral surface of the outer shaft and the bearing of the counter-rotating propeller device for ships of the present invention will be explained with reference to the following nine drawings. Fig. 2 is a diagram showing one embodiment of the device of the present invention. And.
1は内軸、2は外軸、3は船体、4は内軸に固定の船尾
側プロペラ、5は外軸に固定の船首側プロペラ、6は外
軸の内周面に固定の内軸支持用ころがり軸受、7は船体

A;内軸の回転方向、矢印13ル外輔の回転方向である
。1 is the inner shaft, 2 is the outer shaft, 3 is the hull, 4 is the stern propeller fixed to the inner shaft, 5 is the bow propeller fixed to the outer shaft, 6 is the inner shaft support fixed to the inner peripheral surface of the outer shaft 7 is a sliding bearing for supporting the outer shaft fixed to the hull; 8 is a foil seal; arrow A; direction of rotation of the inner shaft; arrow 13, direction of rotation of the outer shaft.
内佃11はa、 ’IIII+ 2の内周面に固定のこ
ろがり軸受6で支持さね外軸2は船体3に固定のすべり
軸受7で支長さねる。The inner shaft 11 is supported by a rolling bearing 6 fixed on the inner circumferential surface of a, 'III+2, and the outer shaft 2 is supported by a sliding bearing 7 fixed to the hull 3.
内軸1は矢印Aで示す回転方向(又は逆向き)。The inner shaft 1 rotates in the direction indicated by arrow A (or in the opposite direction).
外軸2け矢印13で示す回転方向(又は逆向き)に9図
示しない主イ幾により同回転数で逆方向の回転が力えら
ノ9るか、内軸1の支持軸受がころがり軸受であるため
、内・外軸が同回転数で逆向きに回転しても内軸支持軸
受としての負荷能力は問題なく保有、糺持さねる。The support bearing of the inner shaft 1 is a rolling bearing. Therefore, even if the inner and outer shafts rotate in opposite directions at the same rotation speed, the load capacity as an inner shaft support bearing is maintained without any problem.
