Abstract
Description
Es gibt Systeme und Entwicklungen zur Schlagüberlagerung von Rollenbohrwerkzeugen zum Tunnel- und Schachtbohren sowie zum Schlitzen und Abtragen von Beton, Gestein, Mineralien und dgl. unter Verwendung schnellaufend angetriebener Exzenter mit auf ihnen drehend gelagerten, gegengewuchteten und untersetzt langsamer drehend angetriebenen schlagüberlagerter Rollenmeißel konstanter Drehzahlen und konstant hohen Werkzeugumfangsgeschwindigkeiten. Bereits diese Technik hat gezeigt, daß der Energiebedarf sowie der erforderliche Andruck nur noch 1/3 konventioneller Werkzeuge beträgt - bei vergleichsweise geringem Werkzeugverschleiß.There are systems and developments for overlaying roller drilling tools for tunnel and shaft drilling as well as for slitting and removing concrete, stone, Minerals and the like using high-speed eccentrics with them rotatably mounted, counterbalanced and geared slower rotatably driven impact-superimposed roller chisel at constant speeds and constant high Tool peripheral speeds. This technique has already shown that the Energy requirements and the pressure required only 1/3 of conventional tools is - with comparatively little tool wear.
In sehr harten und abrassiven festen Gesteinen oder Mineralien bedingen u.a. die hohen Werkzeugumfangsgeschwindigkeiten zwangsläufig eine geringere Schlageffizienz sowie hohen Verschleiß der Werkzeuge - bis hin zur Unwirtschaftlichkeit oder gar Unmöglichkeit der Verwendung dieser Technik.In very hard and abrasive solid rocks or minerals, the high Tool peripheral speeds inevitably result in lower impact efficiency as well high tool wear - to the point of inefficiency or even impossibility using this technique.
Auf der Basis der Erfahrungen mit o.a. exzenterschlagüberlagerten Rollenmeißeln wurde ermittelt und wird erfindungsgemäß beansprucht, daß man zur Maximierung der Löseleistung die optimale Drehrichtung und Werkzeugdrehzahl sowie optimale Drehrichtung des Exzenters sowie die optimale Amplitude auf das jeweils zu bearbeitende Material zunächst ermitteln und danach einstellen muß, um maximale Löseleistungen bei geringst möglichem Werkzeugverschleiß zu erzielen.Based on the experience with the above eccentric impact superimposed roller chisels determined and claimed according to the invention that to maximize the Dissolving power the optimal direction of rotation and tool speed as well as optimal Direction of rotation of the eccentric as well as the optimal amplitude on the particular one to be machined First determine the material and then adjust it to achieve maximum dissolving performance to achieve the lowest possible tool wear.
In der Figur 1, nur einem Ausführungsbeispiel, wird nur eines der exzenterschlagüberlagerten Systeme beschrieben. Hierbei ist (1) die in (2) exzentrisch gelagerte Exzenterwelle mit dem Gegengewicht (12) an der über (3) schnelldrehend angetriebenen Exzenterhülse (2). Mit (1a) ist das zusätzlich verstärkende vordere Lager bezeichnet (siehe auch Figur 4). Der Innenzahnkranz (4) des Untersetzungsgetriebes ist mit der Welle (1) verbunden. Der Außenzahnkranz (5a) an der An-/ Abtriebswelle (5) ist im Gehäuse zentrisch gelagert und wird über (17) gedämpft gestellfest gehalten, wenn die optimalen Drehzahlen mit dem erforderlichen Untersetzungsverhältnis zuvor ermittelt und entsprechend installiert wurden (z.B. Exzenterwellendrehzahl 3.100 U/min, Werkzeugdrehzahl 65 U/min und Amplitude optimiert z.B. 5,5 mm). Die Regulierung und damit Optimierung der Drehzahl und -Richtung der Welle (1) mit dem jeweiligen Werkzeugen (6-8) erfolgt erfindungsgemäß jedoch über den Zapfen (5) aller Figuren. In Figure 1, only one embodiment, only one of the eccentric impact superimposed systems. Here, (1) is eccentric in (2) mounted eccentric shaft with the counterweight (12) on the over (3) rotating quickly driven eccentric sleeve (2). With (1a) is the additional reinforcing front bearing referred to (see also Figure 4). The internal ring gear (4) of the reduction gear is with connected to the shaft (1). The external ring gear (5a) on the input / output shaft (5) is in the Housing mounted centrally and is held in place by (17) damped frame when the optimal speeds with the required reduction ratio previously determined and have been installed accordingly (e.g. eccentric shaft speed 3,100 rpm, Tool speed 65 rpm and amplitude optimized e.g. 5.5 mm). Regulation and thus optimization of the speed and direction of the shaft (1) with the respective According to the invention, tools (6-8), however, take place via the pin (5) of all figures.
In der Figur 2 ist ein flächig arbeitendes Werkzeug (6) dargestellt, in der Figur 3 ist unter (7) ein fräsendes schlitzendes Werkzeug dargestellt. Bei der Figur 4 handelt es sich um exzenterinduziertes schlagendes Abrollen ein- oder zweiseitig konischer Disken, mit oder ohne Verzahnung, hier mit Verzahnung (8) und Hilfsantrieb über (5), um entweder die exakte Eigenabrolldrehzahl einhalten zu können und ein Schleißen, Schleifen oder gar Stehenbleiben zu verhindern oder um bei verzahnten Werkzeugen einen Fräseffekt zur Erhöhung der Löseleistung durch Erhöhung oder Reduzierung der exzenterinduzierten Selbstabrolldrehzahl zu überlagern. Hierfür wird gesonderter Schutz beansprucht.FIG. 2 shows a flat tool (6), in FIG. 3 it is shown under (7) a milling slitting tool is shown. FIG. 4 is eccentric-induced striking rolling on one or two sides of conical discs, with or without toothing, here with toothing (8) and auxiliary drive via (5) to either the to be able to maintain the exact self-unwinding speed and a grinding, grinding or even To prevent it from standing still or to create a milling effect on toothed tools Increasing the dissolving power by increasing or reducing the eccentrically induced Overlay self-unrolling speed. Separate protection is claimed for this.
Die Figur 5 zeigt den getrennten Antrieb für den Exzenter und exzenterinduziert drehende Werkzeuge, hier ohne (5) [Figur 4], jedoch mit der beanspruchten verstärkendem Lager (1a) und dem die extremen axialdruckaufnehmenden hydrostatischen Gleitlagerung (9), (10). Für dieses System und deren Kombination wird gesonderter Schutz beansprucht - mit und ohne (5) [Figur 4].Figure 5 shows the separate drive for the eccentric and eccentrically induced rotating Tools, here without (5) [Figure 4], but with the reinforcing bearing claimed (1a) and the extreme axial pressure-absorbing hydrostatic sliding bearing (9), (10). Special protection is claimed for this system and its combination - with and without (5) [Figure 4].
In den Figuren 6 und 7 sind die Schlagkurven der Exzenteraktivierung bei verschiedenen Drehzahlen resp. Umfangsgeschwindigkeiten der Werkzeuge dargestellt, im Beispiel bei gleichbleibender Drehzahl und gleicher Drehrichtung der Exzenterwelle (9). Im Bereich der Figur 6 sind die radialen Schläge dargestellt, bis hin zur Werkzeugdrehzahl 0. Bei Werkzeugdrehzahlen darüber, die jeweils über (5) regulierbar sind, werden die Schläge systembedingt linear nach außen gerichtet (Figur 7). Im Bereich des Pfeiles der Figur 7 liegt z.B. die exzenterinduzierte antriebslose Selbstabrolldrehzahl der linear nach außen schlagenden Werkzeuge.In Figures 6 and 7, the impact curves of the eccentric activation are at different Speeds resp. Circumferential speeds of the tools shown, in the example at constant speed and direction of rotation of the eccentric shaft (9). In the field of Figure 6 shows the radial strokes up to the tool speed 0. At Tool speeds above this, which can each be regulated via (5), become the blows system-related linearly directed outwards (Figure 7). 7 lies in the area of the arrow e.g. the eccentrically induced driveless self-unwinding speed of the linear outward hitting tools.
In der Figur 8 ist nur eine andere Bauart der Aktivierung dargestellt, wobei der Antrieb der Werkzeuge über (5) und (11) außen erfolgt - über Kardan, Mitnehmer oder das Zahnradpaar entsprechend Figur 1 (4).In Figure 8, only another type of activation is shown, the drive of the Tools via (5) and (11) are made on the outside - via cardan, driver or that Gear pair according to Figure 1 (4).
