| Zusammenfassung: | A track roller (26) includes a roller housing (28), a roller shaft (76) extending through the roller housing (28), and a collar (60). The collar (60) includes a center body (62) that is interference fit on the roller shaft (76), and a seal carrier (74). A gap (96) extends radially between the center body outer surface (72) and a face seal assembly (84) that remains axially compressed between the seal carrier (74) and the roller housing (28). An oil void (100) is formed in the center body (62) and fluidly connected to the gap (96) to provide an increased oil volume for lubrication and heat dissipation.
一种履带滚轮(26)包括滚轮壳体(28)、延伸通过滚轮壳体(28)的滚轮轴(76)、以及轴环(60)。轴环(60)包括过盈配合在滚轮轴(76)上的中心体(62)，以及密封载体(74)。间隙(96)在中心体外表面(72)和面密封组件(84)之间径向地延伸，所述面密封组件在密封载体(74)和滚轮壳体(28)之间保持轴向压缩。油空隙(100)形成在中心体(62)中并且流体地连接到间隙(96)以提供用于润滑和散热的增加的油体积。 |
