Abstract:
1. A two-roll machine for high-pressure crushing of granular material, with two counter-rotating driven rolls, with roll shafts mounted rotatably in bearing housings and separated from one another by a roll gap, wherein a planetary gear unit whose input stage is driven by a drive motor is mounted on a roll shaft drive journal of each of the rolls extending out of the machine frame as a shaft-mounted gearbox, comprising: a machine table with a table platen that can move back and forth parallel to the roll shaft in at least one direction being located underneath the shaft-mounted gearboxes, three vertically and horizontally adjustable supporting rests being arranged in a triangle on the table platen on which the respective shaft-mounted gearbox is supported offset-free during its installation and removal, and hydraulic clamps arranged between the roll shaft drive journal and an output side of the gearbox such that after offset-free alignment and adjustment of the shaft-mounted gearbox, the table platen with the supported shaft-mounted gearbox is moved and the connection between the roll shaft drive journal and the gearbox output side is clamped hydraulically during gearbox installation and relieved hydraulically during gearbox removal.
