摘要:
A linear motion guide system is disclosed in which a clearance between a slider(2) and a guide rail (1) is closed truly to clear foreign matter away from entering inside the system through any end of the slider(2) traveling on the guide rail (1). Thus, the linear motion guide system is befitting to severe working environment where much foreign matter occurs. A highly-tight sealing unit(3) is provided which is comprised of a cassette(21) constituted with a front panel(23) and an enclosure(22), a sealing plate(20) stowed into the cassette(21), and a rear panel(9) to close an open edge of the enclosure(22). The sealing plate(20) is composed of an intermediate spongy(42) medium(34) flanked by skin layers(33), and lubricant is forcibly absorbed in pores or cells(36) in the spongy layer(42).
摘要:
Eine Abstreifvorrichtung zur Führung über eine Oberfläche eines Körpers dient zur Reinigung von dessen Oberfläche. Hierzu liegt zumindest eine Abstreiferlippe (9) der Abstreifvorrichtung gegen die Oberfläche an und wird mit einer Relativbewegung zwischen dem Körper und der Abstreifvorrichtung in eine vorgesehene Abstreifrichtung der Abstreiferlippe über die Oberfläche geführt. Die Abstreiferlippe (9) weist mindestens zwei unlösbar miteinander verbundene Bereiche mit unterschiedlichen Werkstoffen auf, wobei die zumindest zwei Bereiche in Bezug auf die vorgesehene Richtung der Relativbewegung hintereinander angeordnet sind. Um mit einer solchen Abstreifvorrichtung über lange Zeit gute Abstreifergebnisse selbst unter anspruchsvollen Einsatzbedingungen zu erzielen kann vorgesehen sein, dass jeder der beiden Bereiche einen Kontaktflächenbereich (12, 16) aufweist, der zur Anlage gegen die zu reinigende Oberfläche während der Ausführung der Relativbewegung dient, dass die Kontaktflächenbereiche (12, 16) hierbei unterschiedliches Verschleissverhalten aufweisen, und dass einer der Bereiche in Bezug auf die vorgesehene Abstreifrichtung und zumindest in ihrem Kontaktbereich eine Dicke aufweist, die mindestens um den Faktor drei grösser ist als die Dicke des anderen Bereichs der Abstreiferlippe.

A spacer (5) for a linear motion apparatus (1) is to be interposed alternately between balls (4) arranged in an endless circulation passage of the linear motion apparatus (1). The spacer (5) has a body portion comprising spherical retaining surface (11) portions formed for supporting the balls (4) on both end portions thereof in an advancing direction of the spacer (5) when moving in the endless circulation passage and a circumferential surface portion constituting an outer peripheral portion of the spherical retaining surface portions (11). The spherical retaining surface portion (11) has a radius of curvature smaller than a diameter of the ball (4) and the circumferential surface portion is provided with a groove (13) extending in the circumferential direction thereof so that one of the spherical retaining surface portions (11) is elastically deformable towards another one thereof. The spacer (5) is preferably applicable to various kinds of linear motion apparatus (1). Further, rollers as rolling members may be utilized in place of the balls (4).
摘要:
Die Erfindung betrifft eine Linearführung (1), umfassend mindestens eine Profilschienenführung (2), wobei die Profilschienenführung eine Führungsschiene (3) aufweist, die auf einem Trägerelement (4) befestigt ist, und wobei die Profilschienenführung Führungswägen (5) aufweist, die mit einem in eine translatorische Richtung (T) relativ zum Trägerelement verschiebbaren Tischelement (6) verbunden sind. Um bei hoher Tragfähigkeit einen größeren Verschiebeweg zu ermöglichen, sieht die Erfindung vor, dass der mindestens einen Profilschienenführung mindestens drei Führungswägen zugeordnet sind, wobei die Linearführung so ausgebildet ist, dass mindestens einer der Führungswägen über ein axiales Ende (7, 8) der Führungsschiene hinaus in translatorische Richtung verfahren werden kann.

For a linear movement guide (10) with a guide rail (12) and a carriage (14) supported on the guide rail (12) on rollers (26), in which the guide rail (12) has coverable through apertures (32) for securing components (18) for attaching the guide rail (12) to a supprot, said apertures opening into a surface (34a) of the guide rail (12) away from the support (16) and arranged in the range of movement of the carriage (14), the proposal is for a cover strip (40) made of elastic strip material, of a central section (42) covering the surface (34a) over its entire width perpendicular to the longitudinal direction of the guide rail and two inwardly angled edge sections (44a, 44b) parallel to the longitudinal direction of the guide rail, each to engage in an undercut (48) in both side surfaces (30) of the guide rail (12) adjacent to the surface (34a) thereof widthwise, in the edge region between the surface (34a) and the side surface (30).
摘要:
An object of the invention is to provide a method of manufacturing a rolling element string wherein a smaller rolling element string can be manufactured easily at low cost, and a rolling element string being superior in tensile strength and flexural strength even after downsizing can be manufactured. The present invention to achieve the object is a method of manufacturing a rolling element string having a number of rolling elements (3;30) aligned and rollably retained at prescribed intervals, comprising a first step of forming a flat band shaped belt member (21) with a synthetic resin, a second step of forming retaining holes (20;31) aligned on said belt member (21) in a row for receiving the rolling elements (3;30) loosely, and a third step of aligning the rolling elements (3;30) within said retaining holes (20;31) and forming the spacer portions (22;32) between the respective adjacent retaining holes (20;31) by injection molding for retaining said rolling elements (3;30) with said rolling elements (3;30) used as cores, so that said rolling elements (3;30) are trapped within said retaining holes (20;31).
摘要:
A rolling guide unit comprises a movable member provided with a pair of support portions extending from lateral end portions of a main body portion so as to provide a recessed portion between the main body portion and both the support portions, a guide rail disposed in the recessed portion of the movable member so that side surfaces of the guide rail face the inner surfaces of the support portions, respectively, and a number of rolling members disposed to be rollable between corresponding rolling member rolling grooves formed to the guide rail and the support portions of the movable member so that each of the rolling members contact the rolling member rolling grooves at two contact points and the the rolling members apply load to the rolling member rolling grooves, the movable member and the guide rail being relatively movable through the rolling of the rolling members. Each of the rolling member rolling grooves has an arcuate shape in section having radius of curvature larger than that of the rolling member and the contact points are displaceable along the arcuate shape of the rolling member rolling groove.
