线性导向装置
摘要：
一个线性导向装置在两个相邻的滚子(9)之间具有限制件(15)。该限制件(15)具有其左侧面部分和右侧面部分与滚子(9)的端面部分平行的限制件体(16)；从该限制件体(16)的左侧面部分向着两个相邻滚子(9)的端面部分伸出，并与在循环通道(21)的一个壁面部分中形成的第一个导向槽(22)配合的第一个臂部分(19)；与在该限制件体(16)的右侧面部分上的，与该第一个臂部分(19)平行，和与在该循环通道(21)的另一个壁面部分中形成的第二个导向槽(23)配合的第二个臂部分(20)。该限制件体(16)和该臂部分(19，20)的高度满足条件表达式(H1-H2)/2＜(DW-w)/2，而且H1＜Dw，H2＜W，式中H1为在与滚子的轴向方向垂直的方向上的限制件体(16)的高度；H2为在与滚子的轴向方向垂直的方向上的臂部分(19，20)的高度，W为在与滚子的轴向方向垂直的方向上的导向槽(22，23)的宽度；DW的为滚子(9)的直径。
摘要（英）：

A linear guide device has a retaining piece (15) between two adjacent rollers (9). The retaining piece (15) has a retraining piece body (16) having left side-face section and a right side-face sectionthat are parallel to the end face sections of the rollers (9), a first arm section (19) extending from the left side-face section of the retaining piece body (16) toward the end face sections of thetwo adjacent rollers (9) and fitting in a first guide groove (22) formed in one wall surface section of a circulation path (21), and a second arm section (20) provided on the right side-face section of the retaining piece body (16) so as to be parallel to the first arm section (19) and fitting in a second guide groove (23) formed in the other wall surface section of the circulation path (21). Theheights of the retaining piece body (16) and the arm sections (19, 20) satisfy the conditional expression of (H1 - H2)/2<(Dw -W)/2, where H1 is the height of the retaining piece body (16), in the direction perpendicular to the axial direction of a roller; H2 the height of the arm sections (19, 20) in the direction perpendicular to the axial direction of the roller; W the width of the guide grooves(22, 23) in the direction perpendicular to the axial direction of the roller; and Dw the diameter of the roller (9).
