Definitions

• the systems according to the invention have the advantage that their activation means that they require at least 50% less drive, pressure and propulsion - in one version with optimal balancing they even run absolutely free of vibrations - require considerably lighter machines, experience has shown that they can process any type of rock and hardness can and also work at comparatively high speeds - designed as rollers are particularly suitable for removing road surfaces - and in spherical form particularly suitable for so-called partial cut / boom machines; - Separate protection is requested for both applications - but especially for the extremely compact construction / combination according to the invention, which on the other hand also enables a particularly wide working surface.
• the roller that rotates on the crankshaft or eccentric sleeve and has two bearings on the outside, e.g. 400 mm diameter can be driven separately - e.g. at 100 rpm - via chain, V-belt, gear wheels or the like; but also rotate without drive e.g. Discs with rollers slowly reverse to the direction of rotation of the eccentric shaft or sleeve.
• Counterweights for balancing can be readjusted - preferably from the outside.
• two high-speed, synchronously driven imbalances which are offset in opposite directions and run against one another in the interior of the rotating rollers / balls and which are powerful Generate linear impact, which in particular increases the speed of advance in hard rock and significantly reduces the necessary pressure forces.
• FIG. 1 shows the removal roller -1- provided with picks or the like, which rotates only slowly due to a drive which is not shown in this figure and belongs to the prior art; -2- is a high-speed crankshaft, -3- is e.g. adjustable counterweight for balancing by loosening a clamping screw and turning it on the shaft; -4- are the external bearings on the crankshaft and in the holders; -5- are the brackets and the crankshaft is driven via -6-.
• Figure 2 -7- is a removal tool designed as a ball - activation, drive etc take place according to Figure 1.
• -8- is a special type of unbalance, which can generate an additional stroke in any position for eccentric activation; - separate protection is requested for this.
• the second drive takes place on the other outside of the roller, ball or Like.
• the drive shaft -16- which is synchronously offset by 180 ° to the unbalance -13- but driven in opposite directions in order to produce a linearly directed additional massive stroke.
• -17- is an inner ring gear arranged on the roller or the like, which runs eccentrically on a stationary outer ring gear which is smaller in amplitude - and thus the roller -9- is set down in slow revolutions in relation to the snowing eccentric sleeve -11-.
• Figure 4 corresponds essentially to Figure 3 - but has the advantage of a one-sided drive.
• 2 disk and bevel gears are provided in the embodiment shown -20- and -21-.
• the slow-running roller or the like is preferably driven again via the gear pair -22-;
• Both high-speed imbalance shafts and the eccentric sleeve are driven on one side and / via shaft -23- and gear pairs -24- and -25-.
• the holding arms or the like. -26- are buffered radially or linearly, suspended in a spring-loaded manner on the machine frame or the like during the oscillating work according to FIGS. 2, 3 and 4 - so that they can be moved by the size of the respective amplitudes.
