    • An apparatus for limiting sliding wear and kick-back wear in straight sidebar chains as well as offset sidebar chains includes a wear bar which is attached to the outer surface of the chain's sidebar. The wear bar includes a main body portion having a forward wear bar end in opposed relation to a rearward wear bar end. An inner wear bar surface is positioned adjacent the outer surface of the chain's sidebar and is separated from an outer wear bar surface by a distance at least as great as the distance by which the chain's pin heads extend beyond the sidebars. In one embodiment, the upper edge of the wear bar includes a pair of semi-circular openings which fit closely adjacent the protruding pin heads. In another embodiment, the openings in the wear bar fully encircle the pin heads. A recess formed in the lower wear bar edge is used to weld the wear bar to the chain's sidebar. The lower edge of the wear bar may also be hardened to limit wear to the wear bar itself.
    • 用于限制直边侧链条以及偏移侧边栏链条中的滑动磨损和反冲磨损的装置包括连接到链条侧边缘的外表面上的耐磨条。 磨损杆包括主体部分,其具有与向后磨损杆端部相对的前部磨损杆端部。 内部耐磨条表面位于链条侧边栏的外表面附近,并且与外部耐磨条表面分开至少与链条销头延伸超过侧边栏的距离一样大的距离。 在一个实施例中,磨损杆的上边缘包括一对紧密邻近突出销头配合的半圆形开口。 在另一个实施例中,磨损杆中的开口完全环绕销头。 在下部耐磨条边缘形成的凹陷用于将耐磨条焊接到链条的边栏上。 耐磨条的下边缘也可以被硬化以限制耐磨条本身的磨损。

    • A preferred embodiment of the invention described herein includes a method and apparatus for providing a seal between at least the outer sidebar and pin bushing of a chain link assembly. The apparatus includes a seal having an outer collar and an inner resilient ring, the outer collar preferably having a mating ridge and the resilient ring being molded onto the collar. This seal also includes outer ribs for providing a sealed contact against the outer sidebar, and may include inner ribs. The seal is part of a chain link assembly positioned between the outer and inner sidebars and surrounding a pin bushing end. A fluid (e.g., grease) may be advantageously placed between the ribs, lubricating the rib—sidebar interface and thereby reducing wear of the ribs.
    • 本文描述的本发明的优选实施例包括用于在链节组件的至少外侧杆和销衬套之间提供密封的方法和装置。 该装置包括具有外套环和内弹性环的密封件,外套环优选地具有配合脊,并且弹性环模制在套环上。 该密封件还包括用于提供与外侧杆的密封接触的外肋,并且可包括内肋。 该密封件是位于外侧和侧边之间并围绕销轴套端的链节组件的一部分。 可以有利地将流体(例如,润滑脂)放置在肋之间,润滑肋 - 侧边界面,从而减少肋的磨损。
