【技术实现步骤摘要】
一种挖掘机链轨总成
本技术涉及工程机械
,用于履带式挖掘机地盘行走系统,具体涉及的一种挖掘机链轨总成。
技术介绍
链轨总成是工程机械的底盘件之一,是所使用的工程机械的一种易损件。链轨总成常用在挖掘机、推土机、履带起重机、摊铺机等工程机械上面。链轨总成面对的工作环境通常是极其恶劣的,需要定时对链轨总成进行维护检修和更换。然而,现有链轨总成因结构设置不合理,在实际使用中需要对链轨总成进行拆除时难以正常将链轨总成拆开,只能是破坏性的强拆,造成强拆处的链节单元被破坏,需要重新进行补充更换,导致操作较为不便、费工费力,同时增加了维修成本,而且密封性能较差加之恶劣的工作环境,污水会和固体颗粒会对链轨造成腐蚀和磨损。
技术实现思路
针对现有技术存在的不足,本技术的目的在于提供一种结构设计合理、密封性能出众、磨损情况较轻、方便链轨安装与拆除、维护与检修方便的挖掘机链轨总成,以解决上述
