Slewing device of electric explosion-proof excavator
The invention relates to the technical field of excavators, and discloses a slewing device of an electric explosion-proof excavator, which comprises a base, the top end of the base is fixedly connected with a fixed tooth holder, an oil storage cavity is formed in the fixed tooth holder, partition plates which are uniformly distributed and are symmetrical in pairs are arranged in the oil storage cavity, and an extrusion cavity is formed between every two adjacent partition plates; a one-way valve I is arranged at the bottom of the partition plate on one side of the extrusion cavity, and a piston rod is movably sleeved with the extrusion cavity. When a transmission gear is rotationally meshed with a fixed tooth holder, teeth on the transmission gear extrude a piston rod in a tooth groove of the fixed tooth holder, so that the piston rod is pressed into an extrusion cavity, and lubricating oil in the extrusion cavity pushes away a one-way valve II and is sprayed out from three openings of a spraying cavity; lubricating oil liquid is sprayed on the tooth surface of the fixed tooth holder and the addendum circle of the transmission gear to form a thick oil liquid layer, so that effective lubrication of the transmission gear and the fixed tooth holder is guaranteed, and damage caused by sudden increase of stress is avoided.
本发明涉及挖掘机技术领域，且公开了一种电动防爆挖掘机的回转装置，包括底座，所述底座的顶端固定连接有固定齿座，所述固定齿座内开设有储油腔，所述储油腔内设有均布的两两对称的隔板，相邻两个所述隔板之间形成挤压腔，所述挤压腔一侧的隔板底部设有单向阀Ⅰ，所述挤压腔内活动套接有活塞杆。本发明通过传动齿轮在转动啮合固定齿座时，传动齿轮上的齿将挤压固定齿座齿槽内的活塞杆，使活塞杆压入挤压腔，从而使挤压腔内的润滑油推开单向阀Ⅱ，从喷射腔的三个开口喷出，使润滑油液喷射在固定齿座的齿面以及传动齿轮的齿顶圆上形成厚厚的油液层，从而保证传动齿轮与固定齿座的有效润滑，避免了应力突然增大所导致的损坏。
