Abstract:
(EN) Lubrication grooves 42A, 42B, which are formed in the inner peripheral surfaces of sliding bearings 27, 28, are formed as inclined grooves having a prescribed incline relative to a line segment C extending in the axial direction of the outer peripheral surface of a fixed support shaft 20. Because the lubrication grooves 42A, 42B are thereby inclined relative to the line segment C extending in the axial direction of the outer peripheral surface of the fixed support shaft 20, the fixed support shaft 20 is prevented from slipping into the inclined lubrication grooves 42A, 42B by a simple configuration, and the sliding bearings 27, 28 can thereby be prevented from vibrating.
(FR) L'invention concerne des rainures (42A, 42B) de lubrification formées dans les surfaces périphériques internes des paliers (27, 28) coulissants, formées sous forme de rainures inclinées ayant une inclinaison prescrite par rapport à un segment linéaire C s'étendant dans la direction axiale de la surface périphérique externe d'un arbre (20) de soutien fixe. Comme les rainures (42A, 42B) de lubrification sont ainsi inclinées par rapport au segment linéaire C s'étendant dans la direction axiale de la surface périphérique externe de l'arbre (20) de soutien fixe, le glissement de l'arbre (20) de soutien fixe dans les rainures (42A, 42B) de lubrification inclinées est empêché par une configuration simple, et il est ainsi possible d'empêcher une vibration des paliers (27, 28) coulissants.
(JA) 滑り軸受27、28の内周面に形成された潤滑溝42A、42Bを、固定支持軸20の外周面の軸線方向に延びる線分Cを基準にして、所定の傾斜を有する傾斜溝として形成した。これによれば、潤滑溝42A、42Bが固定支持軸20の外周面の軸線方向に延びる線分Cを基準にして傾斜されているので、簡単な構成で固定支持軸20が傾斜された潤滑溝42A、42Bにもぐり込むことが抑制され、これによって滑り軸受27、28が振動するのを抑制することができるようになるものである。
