本发明提供了一种润滑履带链轨组件、履带及工程机械,润滑履带链轨组件包括:销轴,其内设置有中空腔;销套,套设在销轴外并形成容纳间隙;链轨节,设置在销套的两端,与销轴和销套配合形成安装腔;密封机构,设置有两组,分别对应设置在销套两端的安装腔内,以密封容纳间隙;压缩机构,包括活塞和伸缩件,活塞可移动地嵌套在中空腔并将其分隔成容纳腔与非容纳腔,容纳腔与容纳间隙连通,伸缩件的一端伸入非容纳腔并与活塞连接,伸缩件被配置为能够在容纳腔的压力减小时伸长。应用该润滑履带链轨组件时,若容纳间隙内的润滑介质减少,伸缩件可伸长并带动活塞移动,利用活塞压缩容纳腔,使容纳腔内的润滑介质流入容纳间隙,避免润滑效果下降。
The invention provides a lubricating caterpillar track assembly, a caterpillar track and engineering machinery, the lubricating caterpillar track assembly comprises: a pin shaft, which is internally provided with a hollow cavity; the pin sleeve is arranged outside the pin shaft in a sleeving manner and forms a containing gap; the caterpillar track sections are arranged at the two ends of the pin sleeve and matched with the pin shaft and the pin sleeve to form a mounting cavity; the two groups of sealing mechanisms are correspondingly arranged in the mounting cavities at the two ends of the pin sleeve respectively so as to seal the accommodating gap; the compression mechanism comprises a piston and a telescopic part, the piston is movably nested in the hollow cavity and divides the hollow cavity into a containing cavity and a non-containing cavity, the containing cavity is communicated with the containing gap, one end of the telescopic part extends into the non-containing cavity and is connected with the piston, and the telescopic part is configured to extend when the pressure of the containing cavity is reduced. When the lubricating caterpillar track assembly is applied, if the lubricating medium in the containing gap is reduced, the telescopic piece can extend and drive the piston to move, the containing cavity is compressed through the piston, the lubricating medium in the containing cavity flows into the containing gap, and the lubricating effect is prevented from being reduced.
