The invention relates to the technical field of manufacturing of high-performance, high-reliability and long-service-life sealing, transmission, fastening, hydraulic and pneumatic products or elements, in particular to a self-lubricating working roll lifting device. A self-lubricating space block is cubic and is filled with self-lubricating materials, a nut of a ball screw is integrally soaked inthe self-lubricating space block, a screw hole is vertically formed in the center, an upper screw and a lower screw of the nut penetrate through the screw hole, the bottom of the self-lubricating space block is machined into four leakage-proof bottom plates inclining upwards along diagonal lines, and the inner sides of the four corners of the top are machined into arc-shaped rounded corners. The nut of the ball screw is integrally immersed in the self-lubricating space block, the nut, the screws, a roller path and a ball are integrally located in a continuous lubricating environment, rolling friction between the screws and the nut is smoother, the efficiency of converting rotary motion of the screws into linear lifting motion is remarkably improved, and a sealing structure and the leakage-proof bottom plates can prevent glycerin from leaking out of the screw hole due to gravity, and dead corners cannot be formed by material accumulation at the bottom.

    本发明涉及高性能、高可靠性、长寿命密封、传动、紧固、液压、气动类产品或元件制造技术领域,具体涉及一种自润滑工作辊升降装置。自润滑空间块为立方体,内部充满自润滑材料,滚珠丝杠的螺母整体浸于自润滑空间块内,中心竖直开通丝杠孔,螺母上下丝杠穿过丝杠孔,自润滑空间块底部沿对角线加工成四块向上倾斜的防漏底板,顶部四角内侧加工成弧形圆润角。本发明将滚珠丝杠的螺母处整体浸于自润滑空间块内部,将螺母、丝杠、滚道和滚珠整体处于持续润滑的环境,丝杠与螺母之间的滚动摩擦更加顺滑,将丝杠的回转运动转变为直线升降运动的效率显著提升,密封结构和防漏底板,可以防止甘油受重力从丝杠孔漏出,又不会在底部积料形成死角。
