    • A circular coolant seal has a base flange arranged in a base plane perpendicular to the seal axis. A flexible resilient sealing flange is integrally joined at one edge to the base flange and terminates at its opposite edge in a sealing lip located in a sealing plane parallel to and spaced axially from the base plane. The sealing lip has a first portion extending from the base flange angularly away from the base plane and inwardly towards the seal axis to an intermediate hinge portion, and a second portion extending from the hinge portion away from the seal axis and angularly towards the sealing plane. The configuration, flexibility and resilience of the sealing flange is such that axial displacement of the sealing lip in relation to the base flange is accompanied by both axial and radial displacement of the hinge portion.
    • 圆形冷却剂密封件具有布置在垂直于密封轴线的基底平面中的基底凸缘。 柔性弹性密封凸缘在一个边缘处一体地连接到基部凸缘,并且在其相对的边缘处终止于位于与基底平面平行并与轴向相隔的密封平面中的密封唇中。 密封唇缘具有第一部分,该第一部分从基部凸缘角度地延伸离开基部平面并向内朝向密封轴线延伸到中间铰链部分,以及第二部分,其从铰链部分延伸远离密封轴线并且朝向密封平面 。 密封凸缘的构造,柔性和弹性使得密封唇相对于基部凸缘的轴向位移伴随着铰链部分的轴向和径向位移。

    • Bei einem Ölfilmlager für Walzwerkswalzen (3) mit konischem Zapfen (2) kann zwischen der im Preßsitz auf den Zapfen aufgebrachten konischen Lagerbuchse (8), die mit dem Zapfen rotiert und dem konischen Zapfen Kontaktkorrosion aufgrund von Haftreibung entstehen. Um dies zu vermeiden, sind die Schmiernuten (15) in die konische Innenfläche der rotierenden Lagerbuchse (8) schräg verlaufend eingearbeitet, so daß Kriechöl, das im Betrieb aus den Schmiernuten austritt, freie glatte Rotationsteilflächen unter dem Einfluß der Fliehkraft bestreichen kann. Das Schmieröl wird den Schmiernuten (15) über umfangsverteilte Bohrungen (14) zugeführt, die mit dem unter Druck stehenden Ölfilm (13) zwischen der zylindrischen Außenfläche der rotierenden Lagerbuchse und der stationären Lagerbuchse (12) des Walzen-Einbaustückes in Verbindung stehen.
    • 当油膜轴承用于设置有锥形辊颈的轧机辊上时,轴承衬套与辊颈相互配合以与辊颈一起旋转,粘合剂摩擦可能导致轴承衬套和辊颈之间的接触腐蚀。 为了防止这种损害,油槽被加工成旋转的轴承衬套的圆锥形内表面,以便在操作期间允许从油槽中产生的蠕变油通过离心力的作用在未被旋转的旋转部分表面上展开。 通过与存在于​​旋转轴承衬套的圆筒形外表面和辊轴承座之间的固定轴承衬套之间的压缩油膜接触,将润滑油通过孔分布在衬套的圆周上。

    • A bearing preloading device is provided which can easily prevent a compression coil spring from being pulled out without separately using anti-pullout components. A hole (25) is formed in a bearing race (5) or in a separate member (15) from the bearing race, the separate member being axially opposed to the bearing race (5). The hole (25) has an inner periphery constituted by a threaded portion (22) connected to the bottom surface of the hole (25), and a shallow hole portion (26) connected to the edge of the hole (25), and having an inner diameter larger than that of the threaded portion (22). The compression coil spring (21) can be axially screwed into the threaded portion (22) so as to be threadedly engaged in the threaded portion (22). The shallow hole portion (26) is concentric with the threaded portion (22), and has an inner diameter larger than the outer diameter of the compression coil spring (21). The compression coil spring (21) has such a natural length that when the compression spring is not compressed, the compression coil spring (21) axially protrudes from the shallow hole portion (26). The axial length of the shallow hole portion (26) is set such that the compression coil spring (21) can be compressed until the compression coil spring (21) is entirely received in the hole (25).
    • 提供一种轴承预加载装置,其能够容易地防止压缩螺旋弹簧被拔出而不单独使用抗拔出部件。 孔(25)形成在轴承座圈(5)中或与轴承座圈分离的构件(15)中,分离构件与轴承座圈(5)轴向相对。 孔(25)具有由连接到孔(25)的底表面的螺纹部分(22)和连接到孔(25)的边缘的浅孔部分(26)构成的内周边,并且具有 内径大于螺纹部分(22)的内径。 压缩螺旋弹簧(21)可轴向拧入螺纹部分(22)中以便螺纹接合在螺纹部分(22)中。 浅孔部分(26)与螺纹部分(22)同心,并具有比压缩螺旋弹簧(21)的外径大的内径。 压缩螺旋弹簧(21)具有这样的自然长度,即当压缩弹簧未被压缩时,压缩螺旋弹簧(21)从浅孔部分(26)轴向突出。 浅孔部分26的轴向长度被设定为使得压缩螺旋弹簧21能够被压缩直到压缩螺旋弹簧21被完全容纳在孔25中。
