Agricultural machine and grooved shaft

Abstract:

An agricultural machine includes at least one processing device for harvested material and a drive train for the at least one processing device. The drive train has an output transmission stage with an output shaft for the at least one processing device. The output transmission stage includes an input gear and a grooved shaft connected in a non-rotatable manner to the input gear and the output shaft in such a manner that a drive connection between the input gear and the output shaft is achieved via the grooved shaft. The grooved shaft is provided with a ring groove defining a predetermined breaking point. The ring groove is configured in the drive flow direction between the input gear and the output shaft, and the grooved shaft is accessible through an assembly opening on an input gear side of the grooved shaft. The assembly opening is axially aligned with the grooved shaft.
