本发明公开了一种高可靠性导向轮结构及挖掘机,涉及工程机械领域,用以改善现有导向轮结构的性能,减少甚至防止其出现漏油问题。该导向轮结构包括导向轮、轮轴以及轴承座;轮轴穿过导向轮和轴承座上的通孔,在导向轮和轴承座的配合面设有双层或多层用于防止润滑油泄露的密封结构。上述技术方案提供的导向轮结构,可实现多层密封,故能有效降低出现漏油的几率,提高导向轮结构的性能和使用寿命,具有实用性。

    The invention discloses a high-reliability guide wheel structure and an excavator, relates to the field of engineering machinery, and aims to improve the performance of an existing guide wheel structure as well as reduce and even prevent the occurrence of oil leakage. The guide wheel structure comprises a guide wheel, a wheel axle and a bearing support, wherein the wheel axle passes through the through holes in the guide wheel and the bearing support, and a matched surface of the guide wheel and the bearing support is provided with two layers or multiple layers of sealed structures for preventing leakage of lubricating oil. The guide wheel structure provided by the technical scheme can realize multi-layer sealing, so that the probability of occurrence of oil leakage can be effectively reduced, the performance of the guide wheel structure can be improved, the service life of the guide wheel structure can be prolonged, and the guide wheel structure has practicability.
