Abstract
Kugel-Abstandshalter zum Beabstanden zweier benachbarter Kugeln einer linearen Bewegungseinrichtung, bestehend aus einem Abstandskörper, der zwei einander gegenüberliegende sphärische Endflächen (62) hat, die zwei Abschnitte derselben Kugelform sind, und der eine die beiden Kugeln (3, 3') trennende rotationssymmetrische Fläche (61) hat, wobei der Durchmesser des mittleren Abschnitts der rotationssymmetrischen Fläche (61) um so viel kleiner als der Durchmesser seiner beiden Endabschnitte ist, dass die Kontur der rotationssymmetrischen Fläche (61) an die Kontur der Kugeln (3, 3') angepasst ist, um den Abstand zwischen den benachbarten Kugeln (3, 3') möglichst gering zu halten, und wobei der Durchmesser des Abstandskörpers (6) zwischen den Endflächen (62) kleiner ist als der Durchmesser der Kugeln (3, 3').Ball spacer for spacing two adjacent balls of a linear movement device, consisting of a spacer body, the two opposite ones spherical end surfaces (62), which are two sections of the same spherical shape, and the a rotationally symmetrical surface (61) separating the two balls (3, 3 ') has, wherein the diameter of the central portion of the rotationally symmetrical surface (61) much smaller than the diameter of its two end sections is that the contour of the rotationally symmetric surface (61) adapted to the contour of the balls (3, 3 ') to the distance between to keep the adjacent balls (3, 3 ') as low as possible, and wherein the diameter of the spacer body (6) between the end faces (62) smaller than the diameter of the balls (3, 3 ').
Description
Die vorliegende Erfindung betrifft einen Kugel-Abstandshalter sowie eine Kugelvorrichtung mit derartigen Abstandshaltern. Bei der Kugelvorrichtung handelt es sich insbesondere um ein Kugellager, eine Kugelumlaufspindel und eine lineare Kugelführung. Die Kugeln können aus unterschiedlichen Materialien, wie z.B. Stahl, Keramik usw. bestehen.The The present invention relates to a ball spacer as well a ball device with such spacers. When the ball device acts it is in particular a ball bearing, a ball screw and a linear ball guide. The Balls can made of different materials, such as Steel, ceramics, etc. consist.
Kugelvorrichtungen basieren auf der Grundtatsache, dass der Rollwiderstand sehr viel kleiner als der Gleitwiderstand ist. So vermeiden beispielsweise bei Kugellagern, Kugelumlaufspindeln und linearen Kugelführungen die verwendeten Kugeln eine unmittelbare Gleitberührung zwischen den relativ zueinander bewegten Teilen.ball devices are based on the basic fact that the rolling resistance is very much less than the sliding resistance. For example, avoid it for ball bearings, ballscrews and linear ball bearings the balls used an immediate sliding contact between the relatively moving parts.

Da die Abstandshalter gemäß der vorliegenden Erfindung mit rotationssymmetrischen Flächen versehen sind, die benachbarte Kugeln zu beiden Seiten des Abstandshalters auf Abstand halten, kommt es zu keiner unmittelbaren Berührung zwischen den Kugeln, so dass keine entsprechenden Geräusche entstehen. Die rota tionssymmetrischen Flächen der Kugel-Abstandshalter ermöglichen eine Drehung derselben relativ zu den Kugeln, so dass es praktisch zu keiner Relativbewegung an den Berührungspunkten zwischen den Kugeln und den Abstandshaltern und somit zu keiner entsprechenden Reibung zwischen ihnen kommt. Da ferner der Durchmesser des Mittelabschnitts der rotationssymmetrischen Fläche des Kugel-Abstandshalters kleiner als der seiner beiden Endabschnitte ist, wird der von den Kugeln eingenommene Raum entsprechend verringert. Die mit diesen Abstandshaltern ausgerüstete Kugelvorrichtung kann daher mehr Kugeln als entsprechende Kugelvorrichtungen des Standes der Technik aufnehmen. Wie erwähnt, ist der Abstandshalter an beiden Enden mit sphärischen Endflächen versehen, die Abschnitte derselben Kugel sind, um gegenseitige Störungen zwischen den Kugeln und den Abstandshaltern zu vermeiden.There the spacers according to the present invention Invention are provided with rotationally symmetric surfaces, the adjacent Keep balls on both sides of the spacer at a distance there is no direct contact between the balls, so that no corresponding noises arise. The rotationally symmetric surfaces allow the ball spacer a rotation of the same relative to the balls, making it practical to no relative movement at the points of contact between the Balls and the spacers and thus no corresponding friction between them comes. Further, since the diameter of the central portion the rotationally symmetric surface the ball spacer smaller than that of its two end portions is, the space occupied by the balls is reduced accordingly. The equipped with these spacers ball device can therefore more balls than corresponding ball devices of the state to record the technique. As mentioned, the spacer is provided at both ends with spherical end faces, the sections of the same sphere are in order to mutual interference between to avoid the balls and the spacers.
