Mechanical automatic lubricating device of excavator
The mechanical automatic lubricating device comprises a shaft seat and a pin shaft which are matched with each other, the shaft seat comprises a shaft tube, two fan-shaped supports are symmetrically arranged at the two ends of the shaft tube, two automatic lubricating devices are arranged in an inner cavity of the shaft tube, each automatic lubricating device comprises a sleeve, and a spiral blade and a spring piece are arranged on the inner wall of each sleeve. The rotating directions of the spiral blades in the two sleeves are opposite, a plurality of oil holes communicated with the spiral blades are formed in the outer walls of the sleeves, the spiral blades can drive lubricating grease to do one-way motion towards the two ends of the shaft tube, ratchets matched with the spring pieces are arranged in the middle of the pin shaft, and the automatic lubricating device can only rotate in one way relative to the pin shaft through matching. Lubricating grease in the oil storage cavity can be effectively utilized to lubricate the lining and the pin shaft, the occurrence of faults such as pin shaft abrasion and axial sleeve shifting caused by insufficient lubrication is reduced, the service life of the excavator is prolonged, and the overall performance of the excavator is improved.
本发明公开了一种挖掘机机械式自动润滑装置，包括相互适配的轴座和销轴，轴座包括两端对称设有两个扇形支撑的轴管，轴管的内腔设有两个自动润滑装置，自动润滑装置包括套筒，套筒的内壁上设有螺旋叶片和弹簧片，两个套筒内螺旋叶片的旋向相反，套筒的外壁上设有若干连通螺旋叶片的油孔，螺旋叶片能够带动润滑脂向轴管两端做单向运动，销轴的中部设有与弹簧片相适配的棘齿，相配合使自动润滑装置相对销轴仅能单向转动；可有效的利用储油腔中的润滑脂对衬套及销轴进行润滑，降低因润滑不足造成的销轴磨损、轴向窜套等故障的发生，提高挖掘机的使用寿命及整体性能。
