摘要： A swing mechanism for a construction machine having a grease bath seal. A grease bath can be disposed on a vehicular base carrier of the machine, and can be coupled with a swing frame. The grease bath seal can then act to prevent intrusion of pollutants or other foreign materials into the grease bath. The seal may act to prevent intrusion of pollutants or other foreign materials over an extended amount of time and can be arranged in such as manner as to improve the durability and tightness of a seal member.

摘要： A swinging pinion on the side of an upper swing structure is meshed with a ring gear which is provided on and around the inner periphery of an inner ring on the side of a vehicular base carrier. A grease bath is provided on the inner side of the inner ring and under a swing frame. A center joint is located in an opening which is provided in the swing frame at the center of swinging motions of the upper swing structure. The grease bath is formed by bath-forming walls around an central top plateau wall which is connected the center joint on the inner peripheral side. An annular seal member of resilient material is interposed between the top plateau wall of the grease bath and the lower side of the swing frame. The annular seal member is formed in a height which is larger than the width of spacing between the top plateau wall and the swing frame. At one side, the seal member is detachably fixed either on the side of the swing frame or on the side of the top plateau wall section. At the other side, the seal member is provided with an annular sliding portion which is held in sliding contact with the other one of the swing frame and the top plateau wall in an inclined posture in a radially inward direction.
摘要翻译： 上摆动结构一侧的摆动小齿轮与设置在车辆基座的侧面上的内圈的内周侧的环形齿轮啮合。 在内圈的内侧和摆动框架下设置润滑脂。 中心接头位于在上部摆动结构的摆动运动的中心处设置在摆动框架中的开口中。 油浴是通过围绕中心顶部平台壁的浴形成壁形成的，中心顶部平台壁连接在内周侧的中心接头。 弹性材料的环形密封件插入在润滑脂的顶部平台壁和摆动框架的下侧之间。 环形密封构件形成为比顶部平台壁和摆动框架之间的间隔宽度大的高度。 在一侧，密封构件可拆卸地固定在摆动框架的侧面或顶部平台壁部分的侧面上。 在另一侧，密封构件设置有环形滑动部分，其在径向向内的方向上以倾斜姿势与摇摆框架和顶部平台壁中的另一个滑动接触。
