    • PROBLEM TO BE SOLVED: To provide a slide bearing structure of a shaft member by which sliding resistance during low temperature can be quickly reduced and cooling operation during high temperature by lubricating oil is not hindered.SOLUTION: In sliding bearing structure of the shaft member in which the lubricating oil is fed between sliding faces of the shaft member 10 and a bearing member 12 which can relatively rotate, annular grooves 16 are formed both ends of an inner peripheral surface of the bearing member 12, and annular members 18 separated from the shaft member and the bearing member are arranged in positions corresponding to the annular grooves 16. The annular members 18 are formed of a material having such a coefficient of thermal expansion that the inner diameter of the annular members becomes smaller than that of the bearing member 12 during low temperature and becomes not less than that of the bearing member during high temperature.
    • 要解决的问题:为了提供可以快速降低低温下的滑动阻力的轴构件的滑动轴承结构,并且不会妨碍在高温下的润滑油的冷却操作。 解决方案:在轴构件的滑动轴承结构中,其中润滑油被供给到轴构件10的滑动面和可相对旋转的轴承构件12之间,形成环形槽16,内周表面的两端 并且与轴构件和轴承构件分离的环形构件18布置在与环形槽16相对应的位置中。环形构件18由具有这样的热膨胀系数的材料形成,即内径 的环状部件在低温下变得比轴承部件12小,并且在高温下变得不小于轴承部件的厚度。 版权所有(C)2012,JPO&INPIT

    • 【課題】本発明は、エンジンの温度が変化する場合であっても、各軸受の同軸度を極力損なわないようにできるクランクシャフトの支持装置を提供する。【解決手段】3つ以上のジャーナル部が形成されたクランクシャフトを支持するクランクシャフトの支持構造は、クランクシャフトの各ジャーナル部を回転可能に支持する軸受と、各軸受の外周面が当接する凹状部分が形成されたシリンダブロックと、シリンダブロックに固定されるとともに軸受の外周面が当接する凹状部分が形成されたキャップ33a〜33dとを備えている。シリンダブロック及びキャップ33a〜33dそれぞれに形成された凹状部分により軸受が設けられる軸受孔38a〜38dが形成されている。各キャップ33a〜33dのうち両端に配置される2つのキャップである端部キャップの熱変形量よりも、それ以外のキャップである中間キャップの熱変形量が大きくされている。【選択図】図5

    • PROBLEM TO BE SOLVED: To provide a slide bearing structure of a shaft member that can reduce slide resistance at a low temperature in an early stage, and does not hinder a cooling operation by lubricating oil at a high temperature.SOLUTION: In the slide bearing structure of a shaft member where the lubricating oil is supplied between sliding surfaces of the relatively rotatable shaft member 10 and a bearing member 12, two annular grooves 16 are formed at both ends of the inner peripheral surface of the bearing member 12. Seal members 18 are arranged at locations corresponding to the annular grooves 16, and formed as other pieces than the shaft member and the bearing member. The seal member 18 is composed of two half-divided parts and formed of a material having a thermal expansion coefficient so that at least a part of the inner diameter of the seal member is smaller than the inner diameter of the bearing member 12 at a low temperature and is the same as or larger than the inner diameter of the bearing member 12 at a high temperature.
    • 要解决的问题:提供一种轴构件的滑动轴承结构,其可以在早期降低低温下的滑动阻力,并且不会在高温下阻碍润滑油的冷却操作。 解决方案:在轴构件的滑动轴承结构中,在相对可旋转的轴构件10的滑动表面和轴承构件12之间供应润滑油的两个环形槽16在内周面的两端形成 密封构件18布置在与环形槽16对应的位置处,并且形成为与轴构件和轴承构件相同的其它构件。 密封构件18由两个半分割的部分组成,并且由具有热膨胀系数的材料形成,使得密封构件的内径的至少一部分在低的位置处小于轴承构件12的内径 并且在高温下与轴承构件12的内径相同或更大。 版权所有(C)2013,JPO&INPIT
