A crawler belt guide wheel device is provided, which comprises a guide wheel, a guide wheel shaft, a guide wheel bearing, a bearing cover, a wheel clamping plate and a guide wheel nut. A through holeis formed in the middle of the guide wheel; annular gaps are formed in the edges of two ends of the through hole; the guide wheel shaft penetrates through the guide wheel middle through hole; the guide wheel bearing is positioned between the guide wheel and the guide wheel shaft; the bearing cover is sleeved outside the guide wheel shaft and is positioned on the outer side surface of the guide wheel bearing; the wheel clamping plate is sleeved outside the guide wheel shaft and is positioned on the outer side of the bearing cover; the wheel clamping plate presses the bearing cover at two ends of the through hole of the guide wheel through the guide wheel nut locked at the end part of the guide wheel shaft; the bearing cover is connected with the guide wheel bearing in a sealed mode, and a combined oil seal is arranged on the outer ring face of the bearing cover in an annular mode. The device has the advantages that the guide wheel rotates at a high speed relative to the bearing cover, internal pressure is formed between the guide wheel and the guide wheel shaft in the rotating process to extrude muddy water outwards, accordingly, muddy water is prevented from seeping inwards, and the sealing problem of the guide wheel bearing is effectively solved through combination with the sealing structure.
本发明为一种履带导向轮装置,它包括导向轮、导向轮轴、导向轮轴承、轴承盖、轮夹板、导向轮螺母;导向轮的中部设有通孔,通孔两端边沿设有环形缺口;导向轮轴穿过导向轮中部通孔;导向轮轴承位于导向轮和导向轮轴之间;轴承盖套设于导向轮轴外并位于导向轮轴承的外侧面;轮夹板套设于导向轮轴外并位于轴承盖的外侧,轮夹板通过锁定在导向轮轴端部的导向轮螺母将轴承盖压在导向轮的通孔两端头;所述轴承盖与导向轮轴承之间密封连接,在轴承盖的外圈面上环设有组合油封。本发明的优点为导向轮相对与轴承盖高速转动,转动过程中在导向轮和导向轮轴之间形成内压将泥水外挤压,从而避免了泥水内渗,再集合密封结构有效的解决了导向轮轴承的密封问题。
