The invention relates to the field of sliding supports, and particularly discloses a low-friction hydraulic sliding support capable of bearing axial force, which comprises a sliding rail and a sliding block arranged on the sliding rail in a sliding manner, and a hydraulic jack for applying axial pressure to a test object is fixedly arranged on the sliding block; a hydraulic oil groove is formed in the side, close to the sliding rail, of the sliding block and connected with a hydraulic oil pump. A hydraulic oil seal is arranged in the hydraulic oil groove and used for sealing a gap between the sliding block and the sliding rail. According to the application, the pressure of the hydraulic oil in the hydraulic oil groove and the external axial pressure are mutually counteracted, and meanwhile, the sliding block and the sliding rail are lubricated through the hydraulic oil, so that the friction force borne by the sliding block during sliding can still be kept small under the condition that the external axial pressure is large, and the friction force can be obtained through calculation.
本申请涉及滑动支座领域,具体公开了一种可承受轴向力的低摩擦液压滑动支座,其包括滑轨和滑动设置于滑轨上的滑块,滑块上固定设置有用于对试验对象施加轴向压力的液压千斤顶;滑块靠近滑轨的一侧开设有液压油槽,液压油槽连接有液压油泵;液压油槽中设置有液压油封,用于密封滑块与滑轨之间的缝隙。本申请通过液压油槽中液压油的压力与外部轴向压力相互抵消,同时通过液压油对滑块与滑轨之间进行润滑,进而在外部轴向压力较大的情况下,仍能保持滑块滑移时受到的摩擦力较小,且摩擦力可以通过计算得出。
