申请号:88107108.0 直线运动滚柱支承装置 本发明是直线运动导轨的直线运动滚柱支承装置,用在要求定位精度高,移动均匀、灵敏的机床定位工作台(如坐标镗床工作合、数控及仿形机床定位工作台)导轨上。由保持器和支承块构成相互贯通的封闭循环通道和开门循环通道,可使满布于循环通道内的圆柱滚子,在其中无限循环,因此达到零件种类少,加工和装配简单,成本低而工作性能更好的目的。
Application No.: 88107108.0 Linear Motion Roller Bearing Device The invention relates to a linear motion roller bearing device for a linear motion guide rail, which is used in a machine tool positioning workbench (such as a coordinate boring machine working combination, a numerical control and a simulation Shaped machine positioning table) on the rail. The retainer and the support block form a closed circulation passage and an open circulation passage which can circulate the cylindrical roller covered in the circulation passage endlessly so as to achieve the advantages of fewer types of parts, simple processing and assembly, and low cost The purpose of better performance.
