The invention relates to a thrust wheel and an assembling method thereof and an excavator, the thrust wheel comprises a wheel body (1), a wheel shaft (2) and two box type sealing pieces (3), the wheel body (1) is provided with a containing cavity (11), the wheel shaft (2) is arranged in the containing cavity (11), the two box type sealing pieces (3) are respectively plugged at two ends of the containing cavity (11), and the box type sealing pieces (3) are respectively and tightly contacted with the peripheral surface of the wheel shaft (2) and the inner wall of the containing cavity (11). According to the thrust wheel, the two ends of the containing cavity are sealed through the box type sealing pieces correspondingly, compared with the structure that sealing is conducted through a floating oil seal, a rubber ring and an end cover, the assembling complexity of the thrust wheel can be greatly reduced, and cost can be saved.

    本发明涉及一种支重轮及其装配方法、挖掘机,其中支重轮包括轮体(1)、轮轴(2)和两个盒式密封件(3),轮体(1)具有容纳腔(11),轮轴(2)设置于容纳腔(11)中,两个盒式密封件(3)分别封堵于容纳腔(11)的两端,且盒式密封件(3)分别与轮轴(2)的外周面和容纳腔(11)的内壁紧密接触。本发明中容纳腔的两端分别通过盒式密封件进行密封,相比于通过浮动油封、胶圈和端盖进行密封的结构来说,可以大大减小支重轮的装配复杂度,还有利于节约成本。
