According to the supporting hydraulic cylinder, the structure of a common hydraulic cylinder is changed, an upper sliding bearing, a lower sliding bearing and an outer shell are additionally arranged on a cylinder barrel, meanwhile, the outer shell is rigidly connected with a piston rod through threads, and therefore the rigidity of the hydraulic cylinder is enhanced, and deformation of structural parts is reduced. Meanwhile, the upper sliding bearing and the lower sliding bearing serve as main supporting parts, so that the contact gap of the metal structural part at the sealing ring is enlarged, contact of the metal structural part at the sealing ring is avoided even if unbalance loading deformation occurs, the surface quality of the contact face of the sealing part is guaranteed, and the risk that the sealing ring is abraded is reduced.
本发明涉及一种支撑液压缸,通过改变普通液压缸的结构,在缸筒上增加了上滑动轴承、下滑动轴承和外壳体,同时将外壳体与活塞杆用螺纹刚性连接,因此加强液压缸的刚性,从而减少结构件的变形。同时让上滑动轴承、下滑动轴承为主要支撑件,从而调大密封圈处金属结构件的接触间隙,即使偏载变形也不让此处金属结构件的接触,从而保证密封件接触面的表面质量,降低密封圈被磨损的风险。
