摘要： The invention discloses a tapered roller bearing, comprising: an outer ring (20); an inner ring (10) having a great diameter side and a small diameter side; a plurality of tapered rollers (30) interposed between the outer ring (20) and the inner ring (10); anda retainer (40) for retaining the tapered rollers (30), the retainer (40) having a great diameter side and a small diameter side. The bearing is characterized in that the small diameter side of the inner ring (10)further includes: a small rib (13) projecting radially outwardly and adapted to restrict an axial movement of the tapered rollers (30); and a cylindrical portion (14) extending axially from the small rib (13) to an axial end of the inner ring (10) and having a diameter smaller than that of the small rib (13). The small diameter side of the retainer (40) extends radially inwardly to an axial end of the inner ring (10) to thereby form an annular portion (41). The inner diameter of the annular portion (41) is smaller than the outer diameter of the small rib (13). The inside circumferential end portion of the annular portion (41) is in adjoining relation with the outer periphery of the cylindrical portion (14) and with a side surface of the small rib (13) to thereby form a labyrinth seal (S).
摘要翻译：本发明公开了一种圆锥滚子轴承，包括：外圈（20）; 具有大径侧和小径侧的内圈（10）（20）和内环（10）之间的多个圆锥滚子（30）; 以及用于保持所述圆锥滚子（30）的保持器（40），所述保持器（40）具有大直径侧和小直径侧。该轴承的特征在于，内圈（10）的小直径侧还包括：径向向外突出并适于限制圆锥滚子（30）的轴向运动的小肋（13）; 和一个从小肋（13）轴向延伸到内环（10）的轴向端的圆柱形部分（14），其直径小于小肋（13）的直径。保持器40的小直径侧径向向内延伸到内圈10的轴向端部，从而形成环形部分41。环形部分（41）的内径小于小肋（13）的外径。环状部41的内周侧端部与圆筒部14的外周和小肋13的侧面邻接而形成迷宫式密封件S.

摘要： When a fluid pressure in a fluid supply passage is higher than a first set pressure, a fluid in the fluid supply passage is supplied to a pressure chamber via a check valve, and when the pressure becomes lower than the first set pressure, the fluid is supplied from a hydraulic pump to the pressure chamber via the check valve. When the pressure becomes higher than a second set pressure, the fluid is discharged from the pressure chamber via a relief valve, and also when the pressure within the pressure chamber becomes higher than a third set pressure which is higher than the first set pressure but is lower than the second set pressure, the supply of the fluid is stopped. With this system, the pressure within the pressure chamber is maintained at a level between the first and second set pressures.

摘要： An end faced on an outer side in a radial direction of a small diameter annular portion of a retainer is disposed on an inner side in a radial direction of a pitch conical face of a taper roller and an end face on an inner side in a radial direction of a large diameter annular portion is disposed on an outer side in the radial direction of the pitch conical face. Further, a portion of the small diameter annular portion opposed to a small diameter end face of the taper roller is disposed on the inner side in the radial direction of the pitch conical face and a portion of the large diameter annular portion opposed to a large diameter end face of the taper roller is disposed on the outer side in the radial direction of the pitch conical face.
