ORIGINAL
Name and Address of Applicant: Actual Inventor(s): Address for Service: Invention Title: Hannelore Bechem Tiefendorferstrasse 87 58093Hagen Germany Ulrich Bechem, Klaus Bechem, Philip Bechem Spruson Ferguson St Martins Tower 31 Market Street Sydney NSW 2000 Optimisation of Eccentric Impact-superimposed Counter-balanced Roller Bits The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845c Optimisation of eccentric impact-superimposed counter-balanced roller bits 1( There are systems and developments for impact superposition of roller boring tools for boring tunnels and shafts, and for slotting and cutting of concrete, stone, minerals and the like using highspeed driven eccentric wheels with constant rotational speeds on their rotationally mounted, Scounter-balanced and geared-down, slower rotating, driven, impact-superimposed roller bits and constant high peripheral speeds of tools. This technology has already shown that the power consumption and the necessary contact pressure are still only 1/3 of conventional tools with comparatively low tool wear.
In very hard and abrasive-resistant stones or minerals, the high tool peripheral speeds inter alia inevitably give rise to lower impact efficiency and high wear of tools leading to an uneconomical condition or even impossibility of using this technology.
*e Based on experience it was determined with the above-mentioned eccentric impact-superimposed roller bits, and it is claimed in accordance with the invention, that the optimum direction of rotation and tool rotational speed as well as optimum direction of rotation of the eccentric wheel, 1! and the optimum amplitude on each material to be worked, is first determined for maximising extraction output, and afterwards has to be adjusted in order to obtain maximum extraction yields with the lowest tool wear possible.
In Figure I, in only one design example, only one of the eccentric impact-superimposed systems is described. In this connection, is the eccentric shaft mounted eccentrically in with the 2 counter-weights (12) on the high-speed eccentric sleeve driven via The additionally strengthened front bearing is marked by (I a) (see also Figure The internal ring gear of the step-down gear is connected to the shaft The external ring gear (5a) on the drive/driven shaft is centrally mounted in the housing and is held fixed to the frame and damped through (17), Swhen the optimum speeds of rotation with the necessary step-down ratios were determined beforehand and installed accordingly eccentric shaft rotational speed 3,100 rpm, tool rotational speed 65 rpm and amplitude optimised e.g. 5.5 mm). The control, and therefore optimisation of the rotational speed and direction of the shaft with each of the tools is however carried out according to the invention through the journal in all figures.
j Figure 2 shows a flat working tool and in Figure 3 a milling slotting tool is represented under Figure 4 shows eccentrically-induced, percussive roll-off single or double sided conical discs, with or without toothing, here with toothing and accessory drive through in order to either be able to meet the exact inherent rolling-off speed of rotation and to prevent an abrading :°oooo action, sliding or even stopping, or to superimpose a milling effect with toothed tools to increase the extraction output by increasing or reducing the eccentrically-induced, automatic roll-off rotational speed. For this, separate protection is claimed.
Figure 5 shows the separate drive for the eccentric wheel and eccentrically-induced rotating tool, here without [Figure but with the strengthened bearing (la) used and the extreme axial load-absorbing hydrostatic sliding bearing arrangement For this system and its combination, separate protection is claimed with or without [Figure 4].
The impact curves of the eccentric wheel activation are represented in Figures 6 and 7, at different 3 rotational speeds and peripheral speeds of the tools respectively, in the example at constant rotational speed and same direction of rotation of the eccentric wheel shaft In the area of Figure 6, the radial impacts are shown, down to tool rotational speed ofO rpm. At tool rotational speeds above that, which are each adjustable through the impacts are aligned linearly outward conditional on the design (Figure For example, the eccentrically induced, unpowered, automatic roll-off rotational speed of the linearly outward impacting tools are in the area of the arrow in Figure 7.
Only one design of activation is shown in Figure 8, in which the tool drive is effected outside through and (11) through universal drive, carrier or the gear pair corresponding to Figure 1(4).
