隧道掘进机切割机及相关制造方法

TUNNEL BORING MACHINE DISC CUTTERS AND RELATED METHODS OF MANUFACTURE
Abstract:
A disc cutter for use on a tunnel boring machine (10) may include a shaft and a cutter assembly (213) rotatably mounted on the shaft (202). The cutter assembly may include a cutter ring (206) extending circumferentially about a central axis (230) and one or more bearing apparatuses (212A, 212B) rotatably mounting the cutter assembly to the shaft. Each bearing apparatuses may include a rotor (226) extending circumferentially about the central axis and a first plurality of superhard bearing elements (248) distributed circumferentially about the central axis. Each first superhard bearing element may be attached to the rotor and may include a bearing surface (254). The bearing apparatuses may further include a stator (224) extending circumferentially about the central axis and a second plurality of superhard bearing elements (234) attached to the stator that are generally opposed to the first plurality of superhard bearing elements of the rotor.
Abstract(Chinese):

用于隧道掘进机（10）的盘式切割机可以包括轴和可旋转地安装在轴（202）上的切割器组件（213）。 切割器组件可以包括围绕中心轴线（230）周向延伸的切割环（206）和可旋转地将切割器组件安装到轴的一个或多个轴承装置（212A，212B）。 每个轴承装置可以包括围绕中心轴线周向延伸的转子（226）和围绕中心轴线周向分布的第一多个超硬轴承元件（248）。 每个第一超硬轴承元件可以附接到转子并且可以包括支承表面（254）。 轴承装置还可以包括围绕中心轴线周向延伸的定子（224）和附接到定子的第二多个超硬轴承元件（234），其大致与转子的第一多个超硬轴承元件相对。
