従来の横軸形のすべり軸受装置はオイルディスクが回転軸と一体になって回転 し、軸受箱内のすべり軸受に潤滑油を供給し、そして潤滑油はヒートパイプで冷 却するものが現われている。 In the conventional horizontal shaft type sliding bearing device, an oil disk rotates together with the rotating shaft to supply lubricating oil to the sliding bearing inside the bearing housing, and the lubricating oil is cooled by a heat pipe. There is.
【0003】[0003]
上記従来構造では、すべり軸受に給油後、熱くなった油がすぐにまたオイルデ ィスクで、汲み上げられるため、回転軸(2)の冷却が十分でない問題があった 。 In the above-mentioned conventional structure, after the lubrication bearing is lubricated, the heated oil is immediately pumped up again by the oil disc, so that the rotating shaft (2) is not sufficiently cooled.
【0004】 本考案の目的は、すべり軸受に給油後、熱くなった油を十分に冷却してから、 オイルディスクに供給して、すべり軸受の冷却を良好にして適用限界を高めたす べり軸受装置を提供することにある。An object of the present invention is to lubricate a plain bearing and then cool the hot oil sufficiently, and then supply it to an oil disk to improve the cooling of the plain bearing and increase the limit of application of the plain bearing. To provide a device.

上記目的を達成するために、本考案においては、軸受箱内の潤滑油をヒートパ イプで冷却し、オイルディスクで潤滑油を汲み上げてすべり軸受を潤滑する軸受 装置において、軸受を潤滑して熱くなって落下した油をヒートパイプの受熱部に 循環してからオイルディスクに到達する循環路を形成する仕切板を設ける。 In order to achieve the above object, in the present invention, in the bearing device in which the lubricating oil in the bearing housing is cooled by the heat pipe and the lubricating oil is pumped up by the oil disk to lubricate the slide bearing, the bearing is lubricated and becomes hot. A partition plate is provided to form a circulation path that circulates the oil that has fallen off to the heat receiving part of the heat pipe and then reaches the oil disc.
【0006】[0006]
上記の構成にすると十分に冷却された潤滑油がすべり軸受に供給されるので、 回転軸とすべり軸受の冷却が良好になり、適用限界を高めることができる。 With the above configuration, the sufficiently cooled lubricating oil is supplied to the slide bearing, so that the rotary shaft and the slide bearing are cooled well, and the application limit can be increased.
【0007】[0007]
以下、本考案の一実施例について、図1ないし図3を参照して説明する。オイ ルディスク(1)を備えた回転軸(2)は、潤滑油(3)を入れた軸受箱(4) 内の支持板(4a)を介したすべり軸受(5)に支承される。軸受箱(4)の上 半部は蓋(4b)になっており、ヒートパイプ(6)を取付け、受熱部(7)は 潤滑油(3)中に挿入しておく。すべり軸受(5)の下部は潤滑油(3)に浸漬 し、その中央部に油吸込口(8)を開ける。オイルディスク(1)は油吸込口( 8)の上方に位置し、すべり軸受(5)内にてディスクパット(9),(10) に挟まれる。また、すべり軸受(5)の上部にはオイルディスク(1)で汲み上 げた余分の油を排出する孔(11)を明け、排油パイプ(12)をすべり軸受( 15)の端部側面迄配設する。そして支持板(4a)の下端に通油孔(13)を 設け、すべり軸受(5)の油吸込口(8)と、支持板(4a)の無い側の軸受端 とを仕切る仕切板(14)を設ける。また、仕切板(14)のヒートパイプの受 熱部(7)側の端部と、前記ヒートパイプの受熱部(7)との間を、軸方向両端 下部のみ通油孔(15)を設けた仕切板(16)を設ける。以上によって、軸受 を潤滑して熱くなって落下した油をヒートパイプの受熱部に循環して冷却されて からオイルディスクに到達する矢印で示す循環路(17)を形成する。 An embodiment of the present invention will be described below with reference to FIGS. The rotary shaft (2) provided with an oil disk (1) is supported by a slide bearing (5) via a support plate (4a) in a bearing housing (4) containing a lubricating oil (3). The upper half of the bearing box (4) is a lid (4b), a heat pipe (6) is attached, and the heat receiving part (7) is inserted into the lubricating oil (3). The lower part of the plain bearing (5) is immersed in the lubricating oil (3), and the oil suction port (8) is opened in the central part. The oil disc (1) is located above the oil suction port (8) and is sandwiched between the disc pads (9) and (10) in the slide bearing (5). In addition, a hole (11) for discharging the excess oil pumped up by the oil disk (1) is opened in the upper part of the slide bearing (5), and the oil drain pipe (12) is extended to the end side surface of the slide bearing (15). Arrange. An oil passage hole (13) is provided at the lower end of the support plate (4a) to partition the oil suction port (8) of the plain bearing (5) from the bearing end on the side where the support plate (4a) is not present (14). ) Is provided. Further, between the end of the partition plate (14) on the heat receiving portion (7) side of the heat pipe and the heat receiving portion (7) of the heat pipe, oil passage holes (15) are provided only at the lower ends of the axial direction. A partition plate (16) is provided. As described above, the circulating path (17) shown by the arrow that reaches the oil disk after the oil that has lubricated the bearing and becomes hot and drops is circulated to the heat receiving portion of the heat pipe and cooled is formed.
【0008】 上記のように構成すると、油吸込口(8)から粘性により潤滑油(3)はオイ ルディスク(1)によって汲み上げられ、すべり軸受(5)を冷却する。そして 、すべり軸受(5)から出た熱い油は、ヒートパイプ(6)によって冷却されて からオイルディスク(1)に到達する循環路(17)を仕切板(14)、(16 )(支持板(4a)も仕切板の役目を果す)によって形成されるので、回転軸( 2)とすべり軸受(5)の冷却作用が大幅に向上し、すべり軸受装置の適用限界 を高めることができる。With the above structure, the lubricating oil (3) is pumped up by the oil disk (1) due to the viscosity from the oil suction port (8), and cools the slide bearing (5). Then, the hot oil discharged from the slide bearing (5) is cooled by the heat pipe (6) and then reaches the oil disk (1) through the circulation path (17) which is divided into partition plates (14), (16) (support plate). Since (4a) also functions as a partition plate, the cooling action of the rotary shaft (2) and the slide bearing (5) is significantly improved, and the application limit of the slide bearing device can be increased.
【0009】[0009]
以上説明したように、本考案によれば、潤滑によって高温になった油を冷却し て低温にし、仕切板によって低温の潤滑油のみをオイルディスクへ循環するよう にしたので、すべり軸受装置の冷却が良好になり、適用限界を大幅に高めること ができる。 As described above, according to the present invention, the oil that has become hot due to lubrication is cooled to a low temperature, and only the low-temperature lubricating oil is circulated to the oil disk by the partition plate. And the application limit can be greatly increased.
