Abstract

The circulating roller spindle system converts rotating movement into straight line movement. The cage (4) for rollers floats freely between the threaded spindle (1) and the enclosing threaded housing (3). The rollers (2) can be arranged also without a cage. The spindle (1), rollers (2) and housing are combined to ensure optimum movement. The rotating movement of the spindle is transmitted to the housing (3) which moves in a straight line or vice versa. The screw threads of rollers engage with the screw threads in the housing and in the spindle.

Description

Rollen-Umlauf-SpindelsystemRoll-circulating spindle system

Die Erfindung bezieht sich auf die Anwendungsmöglich keiten des verfahren eine kreisförmige Bewegung in eine geradlinige Bewegung umzuwandeln.The invention relates to the possible uses of the method convert a circular motion into a linear motion.

Bekannte verfahren sind -Spindel-Mutter-System -Kugelrollspindel - Rollenspindel,auch Satelliten-Bollenspindel genannt Die Werkmale der Erfindung ergehen aus der nachfolgenden Beschreibung, welche Bezug auf die eingereichten 7eichnungen nimmt.Well-known procedures are -spindle-nut-system -ball screw - Roller spindle, also called satellite bolt spindle The work features of the invention come about from the following description, which refers to the drawings submitted takes.

Das in }'ig.l dargestellte System basiert in seiner Drehbewegung au f deu System von Räder-Umlauf-Getrieben, auch Planetengetriebe genannt.Es besteht aus einer Spindel (1), einer bestimmten Anzahl von Rollen (2), einem Gehäuse (3) nd einem Käfig (4). Die Rollen (2) sind in dem zwischen Spindel (1) und Gehäuse (3) freibeweglichen Käfig (4) fixiert und befinden sich als Kontaktglied zwischen Spindel(l) und Gehäuse (3). Spindel (1) und Rollen (2) sind außen, das Gehäuse (3) ist innen profiliert. Die Profilierung ist je nach Bedarf als Gewinde oder mit radialen Rillen ausgeführt.The system shown in} 'ig.l is based in its rotary motion on au f eng System of epicyclic gears, also called planetary gears. It exists from a spindle (1), a certain number of rollers (2), a housing (3) nd a cage (4). The rollers (2) are in between the spindle (1) and the housing (3) freely movable cage (4) and are located as a contact member between Spindle (l) and housing (3). The spindle (1) and rollers (2) are on the outside, the housing (3) is profiled on the inside. The profiling is as required as a thread or with radial Running grooves.

Bei Drehung der Spindel(l) folgen die Rollen(2) planetenartig der Profilierung und erzeugen somit eine geradlinige Bewegung des gegen Drehung gesicherten Gehäuses(t).Umgekehrt kann bei Drehung des Gehäuses (3) eine geradlinioe Bewegung der gegen Drehung gesicherten Spindel (1) erfolgen.When the spindle (1) rotates, the rollers (2) follow the planet-like Profiling and thus generate a straight movement of the secured against rotation Housing (t). Conversely, when the housing (3) is rotated, a linear movement the spindle (1) secured against rotation.

Die geradlinige Bewegung erfolgt je nach Drehzahl und wahlweiser Kombination der Profilierung,wie z.B.P.echtsgewinde, Linksgewinde, Gewindesteigung, Gewindegangzahl und radiale Rillen, mehr oder weniger schnell.The straight movement takes place depending on the speed and optional combination the profiling, such as P. right-hand thread, left-hand thread, thread pitch, number of threads and radial grooves, more or less quickly.

Fig.2 zeigt die Anführung ohne des in Fig.l dargestellten Käfigs (4). Hier kann die max.Anzahl von Rollen(2) ermöglicht werden.Fig. 2 shows the specification without the cage (4) shown in Fig.l. The maximum number of roles (2) can be enabled here.

Der in Fig.l zwischen Spindel(l) und Gehäuse (3) frei angeordnete Käfig (4), welcher zur Montageerleichterung auch mehrteilig ausgeführt werden kann, oder die in Fig.2 ebenfalls frei angeordneten Rollen(2), ermcglichen aufgrund ihrer vollkommen symmetrischen Form sehr große Drehzahlen, kombinierbar mit langsamen oder schnellen geradlinigen Pewegungen bei großer Tragfähigkeit und großem Wirkungsgrad.The freely arranged in Fig.l between spindle (l) and housing (3) Cage (4), which can also be made in several parts to facilitate assembly, or the rollers (2), which are also freely arranged in FIG perfectly symmetrical shape very high speeds, can be combined with slow speeds or fast, straight-line movements with high load-bearing capacity and high efficiency.
