Title (EN) LUBRICATING OIL SUPPLYING UNIT AND BEARING DEVICE
(FR) UNITÉ DE FOURNITURE D'HUILE DE LUBRIFICATION ET DISPOSITIF DE ROULEMENT
(JA) 潤滑油供給ユニットおよび軸受装置
Abstract:
(EN) Provided are a lubricating oil supplying unit and bearing device that can be operated stably for an extended time. A lubricating oil supplying unit comprises a holding unit (lubricating oil tank (30)) that holds lubricating oil to be supplied to the interior of a bearing (11), and a supplying unit (drive circuit (28), pump (29), delivery tube (32), and nozzle (37)) to supply the lubricating oil from the holding unit to the interior of the bearing. The supplying unit comprises: the pump that draws the lubricating oil from the holding unit and that is provided to allow a delivery pressure that is equal to or greater than a reference value to be applied to the lubricating oil; a supply line (delivery tube and nozzle) that is connected to the pump and that extends into the bearing; and a regulating unit (check valve (80)) that causes the lubricating oil to which a delivery pressure equal to or greater than the reference value is applied to circulate in the supply line and that prevents lubricating oil to which a delivery pressure less than the reference value is applied from circulating in the supply line.
(FR) L'invention concerne une unité de fourniture d'huile de lubrification et un dispositif de roulement pouvant fonctionner de manière stable pendant une durée prolongée. Une unité de fourniture d'huile de lubrification comprend une unité de réception (réservoir d'huile de lubrification (30)) qui reçoit l'huile de lubrification à alimenter à l'intérieur d'un roulement (11) et une unité de fourniture (circuit d'entraînement (28), pompe (29), tube de distribution (32) et buse (37)) afin d'alimenter l'huile de lubrification depuis l'unité de réception vers l'intérieur du roulement. L'unité de fourniture comprend : la pompe qui aspire l'huile de lubrification depuis l'unité de réception et qui est fournie pour permettre d'appliquer une pression de distribution qui est égale ou supérieure à une valeur de référence à l'huile de lubrification; une ligne de fourniture (tube de distribution et buse) qui est reliée à la pompe et qui s'étend dans le roulement; et une unité de régulation (clapet anti-retour (80)) qui amène l'huile de lubrification à laquelle une pression de distribution égale ou supérieure à la valeur de référence est appliquée à circuler dans la ligne de fourniture et qui empêche l'huile de lubrification à laquelle une pression de distribution inférieure à la valeur de référence est appliquée de circuler dans la ligne de fourniture.
(JA) 長期に安定して動作させることが可能な潤滑油供給ユニットおよび軸受装置を提供する。軸受(11)の内部に供給される潤滑油を保持する保持部(潤滑油タンク(30))と、保持部から軸受の内部に潤滑油を供給する供給部(駆動回路(28)、ポンプ(29)、吐出チューブ(32)およびノズル(37))とを備える。供給部は、保持部から潤滑油を吸引し、基準値以上の吐出圧力を潤滑油に印加可能に設けられているポンプと、ポンプに接続され、軸受の内部に延在する供給管路(吐出チューブおよびノズル)と、基準値以上の吐出圧力が加えられた潤滑油を供給管路において流通させ、基準値未満の吐出圧力が加えられた潤滑油の供給管路における流通を阻止する調整部(逆止弁(80))を含む。
