    • PROBLEM TO BE SOLVED: To provide an oil film bearing equipped with a compact hydraulic attachment section. SOLUTION: An oil film bearing 10 is arranged in that an inside of cylinder 38 is divided into a first chamber 42 and second chamber 44 by a piston 32, in that a sleeve ring 46 contacts to an end of sleeve 12, and in that an annular thrust component 48 is sandwiched between the sleeve ring 46 and portion adjacent to the cylinder 38 so that it may partially lap over these portions. Additionally, its mechanism is characterized in that the cylinder 38 is advanced in axial direction when the first chamber 42 is pressurized so that the sleeve 12 may be located at its seat position through a thrust constituting component 48 and the sleeve ring 46, and in that the cylinder 38 is retreated in the axial direction when the second chamber 44 is pressurized, then, the sleeve 12 is moved in a direction to which it is pulled out from the seat position through chock assembly 26, 28, and 30 and busing 24.

    • 要解决的问题:提供一种配备有紧凑型液压附接部分的油膜轴承。 解决方案:油膜轴承10布置成通过活塞32将气缸38的内部分成第一室42和第二室44,其中套筒环46接触套筒12的端部,并且 因为环形止推部件48夹在套筒环46和邻近气缸38的部分之间,使得它可以部分地覆盖在这些部分上。 此外,其机构的特征在于,当第一室42被加压时,气缸38在轴向方向前进,使得套筒12可以通过推力构成部件48和套筒环46位于其座位,并且在该位置 当第二室44被加压时,气缸38在轴向方向上被退回,然后,套筒12沿着从座椅位置通过轴承座组件26,28和30拉出的方向移动,并且通气24。 版权所有(C)2007,JPO&INPIT

    • PURPOSE:To prevent the generation of seizure and cracks at a fitting part by providing ceramic coating to the outer circumferential surface of the taper neck- part of a roll and the inner circumferential surface of a sleeve, in a oil-film bearing constituted of a roll journal-part and a bearing box. CONSTITUTION:A taper sleeve 3 is fitted to the outer circumferential surface 2a of a taper neck-part 2 of roll 1, and is tightly fastened and fixed to the neck- part 2 by a sleeve holder 9 and a lock nut 10, and a shell 5 surrounding the outer circumference of sleeve 3 is internally attached to a bearing 4. Next, lubrication-oil supplying holes and oil feeding ports are formed at the box 4 and the shell 5 respectively, to form an oil-film bearing between the sleeve 3 and the shell 5. At that time, ceramic coating is provided to the outer circumferential surface 2a of neck part 2 and the inner circumferential surface 3a of sleeve 3. In this way, fretting phenomena at the fitting parts of the outer circumferential surface of taper neck-part and the inner circumferential surface of taper sleeve are eliminated, thereby preventing the generation of seizure and cracks at the fitting part.
    • 目的:为了通过在辊的锥形颈部的外圆周表面和套筒的内周表面上提供陶瓷涂层来防止在装配部分产生卡塞和裂纹,在油膜轴承中由 滚动轴颈部件和轴承箱。 构成:锥形套筒3装配到辊1的锥形颈部2的外周面2a上,并通过套筒保持件9和锁紧螺母10紧固并固定到颈部2上, 壳体5围绕套管3的外周部内部附接到轴承4.接下来,分别在箱体4和壳体5上形成润滑油供给孔和供油口,以在套筒4和壳体5之间形成油膜轴承 此时,陶瓷涂层被提供到颈部2的外周面2a和套筒3的内周面3a。这样,在外周面的嵌合部分的磨损现象 消除锥形颈部和锥形套筒的内圆周表面,从而防止在配件部分产生卡塞和裂纹。
