Abstract
The invention relates to a drive train for a roller crusher having at least one transmission and a motor, wherein the motor drives the drive shaft of the transmission directly and the output shaft of the transmission directly drives the roller crusher. Driven directly, in this context, means that the force transmission occurs without slippage, meaning not via a belt drive or something similar.
According to the invention, the transmission is designed such that the drive and output shafts are on the same side of the transmission and thus the motor and roller crusher are also arranged on the same side of the transmission. The drive train advantageously thus makes a hairpin bend, by means of which the total length of the crusher can be significantly reduced.
According to the invention, an articulated shaft is particularly preferably arranged between the motor and the transmission or between the transmission and the roller crusher. The motor or the crusher can thus be advantageously arranged offset to the transmission, and the crusher designed to be even smaller. The effort required to align the motor shaft or the shaft of the crusher roller with the transmission shaft is furthermore advantageously eliminated.

Crushing Roller for a Roller Crusher The present invention pertains to a crushing roller for a roller crusher.
Any crusher which reduces the particle size of raw material by means of one or more rotating rollers or shafts and crushing tools arranged thereon is defined as a roller crusher. A variety of structural designs of crushing rollers are known.
In the simplest design, the crushing rollers have a one-piece design and must be replaced as a whole after the crushing tools are worn out. In addition, crushing rollers are known, in which the crushing tools are arranged in so-called crushing shells, wherein the crushing shells are detachably connected to the crushing roller. Thus, it becomes possible to replace the crushing tools without a complete disassembly of the crushing roller. This is particularly advantageous since time and costs required for maintenance can be reduced.
In an alternative design, the crushing tools are designed as crushing chisels, which can be inserted into corresponding openings in the crushing roller.
All prior-art solutions have in common that a change in the configuration of the crushing roller, i.e., a change in the positions of the crushing tools in the circumferential direction for defining an area for meshing is always connected with the replacement of the roller.
The object of the present invention is to propose a crushing roller with variable positions of the crushing tools.
This object is accomplished by a crushing roller according to claim 10 and a support plate according to claim 1, wherein preferred embodiments of the present invention are the subject of the subclaims.
The terms axial, radial and in the circumferential direction refer below to the shaft of the crushing roller.
According to the present invention, the object is accomplished by at least one support plate being arranged between the crushing shells and the shaft, which support plate is detachably connected to said shaft. The support plate is designed here as cylindrical, wherein cylindrical here means that the support plate has the shape of a hollow cylinder with an outer area and an inner area. In this connection, the outer and inner areas may differ from one another, as a result of which a varying wall thickness of the support plate results.
Moreover, a support plate according to the present invention has means for detachable connection to a shaft in the cylinder interior and means for fastening crushing shells to the cylinder outer surface. The axial length of the support plate depends here on the specific application. In the simplest case, a support plate is provided, which supports all crushing tools of the crushing roller.
However, a plurality of support plates may also be arranged axially next to one another. The configuration of the crushing roller may advantageously be changed by replacing the support plate or support plates. Thus, it is possible to change the configuration of the crushing roller by means of a relative change in the circumferential position of the means for detachable connection to a shaft in the interior of the support plate opposite the circumferential position of the means for fastening the crushing shells on the outer surface. The infeed behavior of the crusher may thus be advantageously changed in a simple manner without replacing the entire crushing roller.
The outer cross-sectional shape is particularly preferably an n-gon, especially a pentagon, wherein a crushing shell is to be fastened on each outer surface of the n-gon.
The means for detachable connection to a shaft are particularly preferably an axial tongue and groove connection. For this, a groove or a tongue is prepared in the axial direction to the outside on the shaft and correspondingly on the inner surface of the support plate.
The tongue and groove connection is able to transmit the drive torque of the crushing roller very well and is, in addition, simple to prepare and cost-effective.

This object is accomplished by a crushing roller according to claim 10 and a support plate according to claim 1, wherein preferred embodiments of the present invention are the subject of the subclaims.
The terms axial, radial and in the circumferential direction refer below to the shaft of the crushing roller.
According to the present invention, the object is accomplished by at least one support plate being arranged between the crushing shells and the shaft, which support plate is detachably connected to said shaft. The support plate is designed here as cylindrical, wherein cylindrical here means that the support plate has the shape of a hollow cylinder with an outer area and an inner area. In this connection, the outer and inner areas may differ from one another, as a result of which a varying wall thickness of the support plate results.
Moreover, a support plate according to the present invention has means for detachable connection to a shaft in the cylinder interior and means for fastening crushing shells to the cylinder outer surface. The axial length of the support plate depends here on the specific application. In the simplest case, a support plate is provided, which supports all crushing tools of the crushing roller.
However, a plurality of support plates may also be arranged axially next to one another. The configuration of the crushing roller may advantageously be changed by replacing the support plate or support plates. Thus, it is possible to change the configuration of the crushing roller by means of a relative change in the circumferential position of the means for detachable connection to a shaft in the interior of the support plate opposite the circumferential position of the means for fastening the crushing shells on the outer surface. The infeed behavior of the crusher may thus be advantageously changed in a simple manner without replacing the entire crushing roller.
The outer cross-sectional shape is particularly preferably an n-gon, especially a pentagon, wherein a crushing shell is to be fastened on each outer surface of the n-gon.
The means for detachable connection to a shaft are particularly preferably an axial tongue and groove connection. For this, a groove or a tongue is prepared in the axial direction to the outside on the shaft and correspondingly on the inner surface of the support plate.
The tongue and groove connection is able to transmit the drive torque of the crushing roller very well and is, in addition, simple to prepare and cost-effective.
2 ' The inner cross-sectional shape of the support plate or plates is particularly preferably circular. It is advantageously adapted to the standard shaft shape. As an alternative, rectangular or star-shaped inner cross-sectional shapes of the support plates with corresponding shaft cross sections would also be possible. This is, however, considerably cost-intensive.
Furthermore, a plurality of adjusting springs and grooves as means for detachable connection to a shaft are preferably provided distributed over the circumference. The torque that can be transmitted by the connection may thus be advantageously increased.
Furthermore, the means for fastening the crushing shells on the support plate or support plates are preferably tongue and groove connections. In addition, threaded holes are particularly preferably additionally provided in the radial direction for fastening screws as means for fastening the crushing shells.
This tongue and groove connection especially preferably has a parallelogram-shaped cross-sectional shape, wherein the acute angle of the parallelogram points in the direction of rotation.
Due to the slope of the flank of the tongue, the tangential crushing force thus advantageously generates a force of pressing the crushing shell onto the support plate. In principle, all forms of tongue and groove connection which generate a pressing-on force are preferred.
For clarification, it is noted that the tongue does not have to be an extra component, but rather may also be an integral component of the support plate or the shaft. The tongue is particularly preferably an integral component of the support plate.
In addition, the crushing shell with the support plate preferably has an adjusting spring connection in the circumferential direction, which absorbs axial forces.
Furthermore, a support plate preferably has axially directed and through holes distributed over the circumference. Tension rods are guided through these holes and connected, and particularly screwed, to a fastening element rigidly connected to the shaft. In this connection, the fastening element is, for example, a flange of the shaft with axial holes. The support plates arranged axially next to one another are consequently braced with one another.
Furthermore, a plurality of adjusting springs and grooves as means for detachable connection to a shaft are preferably provided distributed over the circumference. The torque that can be transmitted by the connection may thus be advantageously increased.
Furthermore, the means for fastening the crushing shells on the support plate or support plates are preferably tongue and groove connections. In addition, threaded holes are particularly preferably additionally provided in the radial direction for fastening screws as means for fastening the crushing shells.
This tongue and groove connection especially preferably has a parallelogram-shaped cross-sectional shape, wherein the acute angle of the parallelogram points in the direction of rotation.
Due to the slope of the flank of the tongue, the tangential crushing force thus advantageously generates a force of pressing the crushing shell onto the support plate. In principle, all forms of tongue and groove connection which generate a pressing-on force are preferred.
For clarification, it is noted that the tongue does not have to be an extra component, but rather may also be an integral component of the support plate or the shaft. The tongue is particularly preferably an integral component of the support plate.
In addition, the crushing shell with the support plate preferably has an adjusting spring connection in the circumferential direction, which absorbs axial forces.
Furthermore, a support plate preferably has axially directed and through holes distributed over the circumference. Tension rods are guided through these holes and connected, and particularly screwed, to a fastening element rigidly connected to the shaft. In this connection, the fastening element is, for example, a flange of the shaft with axial holes. The support plates arranged axially next to one another are consequently braced with one another.
3 In addition, the axial inner holes may advantageously be used for detaching the support plates from the shaft. For this, additional holes may also particularly advantageously be provided in the axial direction, which do not form a through hole in the installed state of the support plates.
Thus, it is advantageously possible to compress and thus to detach one support plate after the other through the holes. The compression is preferably hydraulic.
Moreover, a fixed bearing and a movable bearing are preferably provided for mounting the crushing roller. In this case, the fastening element is arranged on the fixed bearing side. The axial forces are thus advantageously fed in by the fastening means in a defined manner.
Particularly preferably, the support plates have a multiple of grooves and tongues as the corresponding grooves and tongues on the shaft. Thus, the same support plate may advantageously be fastened in various circumferential positions on the shaft.
Furthermore, the crushing shells preferably have openings for the insertion of crushing chisels.
The crushing chisels can thus advantageously be replaced in a simple manner.
Particularly preferably, the crushing chisels to be inserted have a circumferential groove in the area to be inserted. In the crushing shells, a corresponding hole is provided, into which a pin is to be inserted, which meshes with the circumferential groove in the inserted state and consequently holds the crushing chisels in the crushing shell. The crushing chisels may thus advantageously be rotated about themselves under load, as a result of which a uniform wear is ensured.
An exemplary embodiment of the present invention is explained below on the basis of figures. In the drawings, Figure 1 shows a shaft of a crushing roller with support plates and crushing shells according to the present invention,

Figure 1 shows a shaft 1 of a crushing roller according to the present invention with three support plates, on which crushing shells 2 are mounted. The shaft 1 is mounted on one side with a fixed bearing 11 and on the other side with a movable bearing 12. The shaft 1 has, furthermore, a flange 13 on the side of the fixed bearing 11.
Figure 2 shows a support plate 2 according to the present invention partially with mounted crushing shells 3, into which round shank chisels 4 are inserted. The support plates 2 have driver springs 21, which absorb the tangential crushing force and in addition are used for fastening the crushing shells 3 on the support plates 2. Furthermore, the support plates 2 have through holes 22 in the axial direction. Tension rods 5, which are seen in Figure 1, are guided through these holes and braced against the flange 13 with nuts 15.
Figure 3 shows the cross-sectional profile of a support plate 2 by means of a lateral view. This plate has a pentagonal outer area with equal side lengths and a largely circular inner area. A
crushing shell 2 is to be fastened on each of the five sides on the outer area, for which a driver spring 21 is provided. The driver spring 21 has the shape of a parallelogram, wherein the front side in the direction of rotation forms the acute angle with the side surface of the support plate 2, as a result of which the tangential crushing force is advantageously used for pressing the crushing shell 3 onto the support plate 2. Furthermore, the axial holes 22 for guiding through the tension rods (five in Figure 1) are seen in Figure 3. Additional, likewise axial holes 25 are used to pull the support plates 2 from the shaft 1 by means of hydraulic pressure. For this purpose, for

Additional, likewise axial holes 25 are used to pull the support plates 2 from the shaft 1 by means of hydraulic pressure. For this purpose, for
5 example, special hydraulic cylinders, which are coupled with one another, are screwed into the holes of the support plates at the end position. For this, these cylinders have an outer thread on the cylinder tube on the side of the piston rod. Since the stroke of the cylinders is limited, i.e., is smaller than the available pull-off length of the support plates themselves, pressing bolts are inserted as piston rod extension into the holes in the corresponding different lengths, with increasing lengths.
Two grooves 26, which correspond with tongues 14 on the shaft 1, are arranged on the inner circular cross-sectional surface. These grooves are used for transmitting the torque from the shaft 1 to the support plates 2.
Figure 5 shows a crushing shell 3, which accommodates two round shank chisels 4, but only one round shank chisel 4 is seen in the figure, the other lies directly behind it, as can be seen in Figure 2.
Toothed front webs 32, which have a wedge-shaped design and consequently support the secondary crushing, are arranged under the round shank chisels 4 in extensively the radial direction. Viewed in the direction of rotation, toothed back plates 33, which likewise have a wedge-shaped design, are arranged behind the round shank chisel 4, and a toothed intermediate web 34, which likewise has a wedge-shaped design, creates the connection to the next round shank chisel 4 arranged behind it.
Last but not least, holes are arranged in the crushing shell 3 for guiding through a pin 34, which represents a loss protection for the round shank chisel 4. In order to prevent a slipping out of the pin 35, its ends are secured with nuts.
Figure 6 shows a sectional view of a round shank chisel 4 in a crushing shell 2. The round shank chisel 4 has a circumferential groove 41 in its rear area. In the inserted state, this circumferential groove 41 corresponds with the holes in the crushing shell 3 for the pin 35 (Figure 4). A striking pin 42 is arranged in the crushing shell 3 behind the round shank chisel 4.
