Abstract

A transmission ( 1 ) for a feed and foodstuff roller mill ( 2 ) with a plurality of rotatably drivable rollers. The transmission ( 1 ) has a bearing housing ( 3 ) in which an input shaft ( 4 ), a first output shaft ( 5 ) and a second output shaft ( 6 ) are accommodated. The input shaft ( 4 ) and the first output shaft ( 5 ) are arranged perpendicular to one another and the first output shaft ( 5 ) and the second output shaft ( 6 ) are arranged parallel to one another. The input shaft ( 4 ) and the first output shaft ( 5 ) are operatively connected to one another via a bevel gearwheel pair ( 7, 7 ′), and the first output shaft ( 5 ) and the second output shaft ( 6 ) are operatively connected to one another via a torque transmitting arrangement.

First claim

The invention claimed is:

1. A feed and foodstuff roller mill comprising at least two rotatably mounted rollers,
wherein a first of said two rotatably mounted rollers is fixedly mounted and a second of said two rotatably mounted rollers is movably mounted, comprising a transmission with
a bearing housing in which:
a first output shaft for driving said first roller, and
a second output shaft for driving said second roller are accommodated, wherein

the first output shaft is coupled to said first roller and the second output shaft is coupled to said second roller; and
the first output shaft and the second output shaft are operatively connected to one another by means of a torque transmitting arrangement,
wherein an input shaft is also accommodated in the transmission,
wherein the input shaft is coupled to a drive,
wherein the input shaft and the first output shaft are arranged perpendicular to one another and the first output shaft and the second output shaft are arranged parallel to one another,
the input shaft and the first output shaft are operatively connected to one another by means of a bevel gearwheel pair,
an axes of the input shaft, an axis of the first output shaft and an axis of the second output shaft lie in a common plane; and
an intersection point of the axis of the input shaft with the axis of the first output shaft is arranged between the bevel gearwheel and the torque transmitting arrangement of the first output shaft.

2. The feed and foodstuff roller mill according to claim 1 , wherein the bevel gearwheel of the input shaft is arranged at a face end of said input shaft.

3. The feed and foodstuff roller mill according to claim 1 , wherein the first output shaft is mounted at its both side ends.

4. The feed and foodstuff roller mill according to claim 1 , wherein the second output shaft is mounted at its both side ends.

5. The feed and foodstuff roller mill according to claim 1 , wherein the torque transmitting arrangement is formed as a spur gearwheel pair.

6. The feed and foodstuff roller mill according to claim 5 , wherein the spur gearwheel pair has a speed reduction ratio of between 1:1.25 and 1:3.

7. The feed and foodstuff roller mill according to claim 1 , wherein the bearing housing encloses the entire transmission.

8. The feed and foodstuff roller mill according to claim 1 , wherein the first roller, which is fixedly mounted, is coupled to the first or second output shaft by means of an elastic clutch.

9. The feed and foodstuff roller mill according to claim 1 , wherein the second roller, which is movably mounted, is coupled to the first or second output shaft by means of a telescopic cardan shaft.
