Definitions
- the invention relates to a two-roll machine, in particular a roller press, consisting of two rolls which are rotatably mounted in a housing and are driven in opposite directions, with gears plugged onto the drive pins of the rolls, which are provided with torque supports for receiving the reaction moments, which are designed as lever plates with two arms and on the one hand with ver the gears firmly are bound and on the other hand are rotatably connected to a torsion shaft via lever arms and levers.
- a roller press consisting of two rolls which are rotatably mounted in a housing and are driven in opposite directions, with gears plugged onto the drive pins of the rolls, which are provided with torque supports for receiving the reaction moments, which are designed as lever plates with two arms and on the one hand with ver the gears firmly are bound and on the other hand are rotatably connected to a torsion shaft via lever arms and levers.
- the gears plugged onto the drive pins of the rolls are provided with torque supports for absorbing the reaction moments, which consist of lever plates with two diametrically opposed arms of the same length, each of which is firmly connected to the gearing are.
- the above-mentioned lever plates are also provided with two equally long, diametrically opposed arms and, on the one hand, are firmly connected to the gearboxes and, on the other hand, can be rotated via a lever and lever arms with a torsion shaft connected.
- This configuration and arrangement of the torque supports ensures that the gearbox is supported without lateral force when the two-roll machine is in operation, but only one gearbox can be arranged on one side of the two-roll machine for reasons of space. This in turn is associated with an increased space requirement.
- the object of the invention is a further improvement of the two-roll machines mentioned at the outset, in particular in terms of design and in their mode of operation.
- lever plate arms rotatably connected to the torsion shaft via linkages and lever arms are of unequal length. Due to this unequal length of the lever plate arms, both gears for the rollers can very advantageously be arranged on one side of the two-roller machine, which not only achieves a considerably more compact design of the two-roller machine as a whole, but also without obstructing the evasive movement of the loose roller relative to the fixed roller both the roller bearings and the machine frame are kept free of lateral forces.
- the lever arms connected to the torsion shaft are of different lengths. Due to this unequal length of the lever arms, which are connected to the torsion shaft, the bearing of the shaft can be relieved partially or even completely of the weight of the transmission and the motor.
- the lever plate arms (16 and 17) which are rotatably connected to the respective torsion shaft (13 and 14) via the linkages (9, 10) and lever arms (11, 12) are of unequal length.
- This unequal length of training as Torque supports serving lever plate arms (16, 17) very advantageously allows an extremely space-saving arrangement of the slip-on gears (5 and 6) on one side of the two-roll machine and thus a very compact, space-saving design of the two-roll machine as a whole. Furthermore, as shown in particular in FIGS.
- the lever arms (11 and 12) connected to the torsion shaft (13 and 14) are of unequal length, specifically the lever arm (11) which extends over the linkage ( 9) is connected to the outer longer lever plate arm (16), a shorter lever arm length (r) than the lever arm (12) with the lever arm length (R), which is articulated via the linkage (10) with the short lever plate arm (17) connected is. Due to this unequal length of the lever arms (11 and 12), the bearing of the shaft can be partially or completely relieved of the weight of the transmission and the drive motor.
- the linkage (9) is subjected to pressure and the linkage (10) is subjected to tension due to the reaction moments (arrow 18) occurring during operation of the two-roll machine.
