Description

T i t e 1: Feder in Rohrform Az: P 21 43 798.9 B e 5 c h r e 1 b u n g: 1.) Feder gekennzeichnet durch 1.1) rohrförmigen Grundkörper, zylindrisch oder konisch, mit kreis-oder polygonförmigem Querschnitt.T i t e 1: Spring in tube shape Az: P 21 43 798.9 B e 5 c h r e 1 b u n g: 1.) Spring characterized by 1.1) tubular body, cylindrical or conical, with a circular or polygonal cross-section.

1.2) Ein- oder mehrreihig in Umfangsrichtung angeordnete Schlitze (ein oder mehrere Schlitze je Reihe) im rohrförmigen Grundkörper.1.2) Slots arranged in one or more rows in the circumferential direction (one or more slots per row) in the tubular body.

1.3) Jede Schlitzreihe ist um eine wählbareTeilungsgröße gegenüber den benachbarten Schlitzreihen so versetzt angeordnet, daß durch die dabei entstehende Schlitzüberlappung gleichgroße Federblätter entstehen, die durch Biegung und Torsion in der Lage sind, Federkräfte aufzunehmen.1.3) Each row of slots is opposite by a selectable pitch size the adjacent rows of slots so offset that through the resulting Overlapping of the slots creates spring leaves of the same size as a result of bending and torsion are able to absorb spring forces.

2.) Die Variierbarkeit der Federkraft und der Federkennlinie erfolgt durch die Einflußgrößen 2.1) Durchmesser "d" des Federkörpers 2.) Höhe H" und Wandstärke 's" des Federkörpers 2.3) Breite b",Teilung t und Länge L111 der Schlitze je Schlitzreihe sowie dem Verhältnis L1:L2 (überlappungsgrad) und der Schlitzreihenzahl "n".2.) The spring force and the spring characteristic can be varied by the influencing variables 2.1) diameter "d" of the spring body 2.) height H "and wall thickness 's "of the spring body 2.3) Width b", pitch t and length L111 of the slots per row of slots as well as the ratio L1: L2 (degree of overlap) and the number of slot rows "n".

2.4) Werkstoffwahl und thermische Behandlung 2.5) Herstellungsmethode 2.6) Einstoff- od. Mehrstoffverbund-Bauweise (Dämpfungscharakteristik). 2.4) Choice of materials and thermal treatment 2.5) Manufacturing method 2.6) Single-material or multi-material composite construction (damping characteristics).

3.) Anwendungsgebiete: Axiale Vorspannung von Rollen- und Gleitlagern, Schnitt-und Stanzwerkzeugbau, Kupplungen, Stoß- und Schwingungsdämpfer, Motoren- und allg. Maschinenbau.3.) Areas of application: Axial preload of roller and plain bearings, Cutting and punching tool construction, clutches, shock and vibration dampers, engine and general mechanical engineering.

4.) Vorteile gegenüber derzeit bekannten Federarten: 4.1) Geringer Raumbedarf 4.2) Geringes Leistungsgewicht 4.3) Paßgenauigkeit in Querschnitt, Länge und Planparallelität der Siirnflächen 4.4) Keine Verdrehung sowie vernachlässigbare Durchmesserveränderung bei Federkraft aufnahme 4.5) Hohe Unwuchtfreiheit durch die rotationssymetrische Massenverteilung im Federkörper 4.6) Hohe Knicksteifheit und Eigenführung 4.7) Weitgehende Verschleiß freiheit 4.8) Anpassungsfähigkeit an geforderte Federkennlinien 4.9) Ein- und mehrteilige Bauweise Die Darstellung und Funktion der Rohrfeder ist der anliegenden Prinzipskizze zu entnehmen.4.) Advantages compared to currently known types of springs: 4.1) Less Space requirement 4.2) Low power-to-weight ratio 4.3) Accuracy in cross-section, length and Plane parallelism of the Siirnflächen 4.4) No twist as well negligible change in diameter when absorbing spring force 4.5) High freedom from unbalance due to the rotationally symmetrical mass distribution in the spring body 4.6) High buckling stiffness and self-management 4.7) Extensive freedom from wear and tear 4.8) Adaptability to Required spring characteristics 4.9) One-piece and multi-part construction The illustration and The function of the Bourdon tube can be seen in the attached schematic diagram.
