Abstract
In order for contaminants (50) that are in particular liquid or highly viscous or solid and impact in an operating portion (40b) of one or 2 processing shafts (40.1, 40.2) that rotate adjacent to each other not to reach bearings (2) of the shafts (40.1, 40.2) which are arranged axially outside of the processing portion (40b) which could damage the bearings a wiping device (6) is arranged there between which is additionally axially shielded by a bearing plate (3) and a splash guard plate (4) wherein the wiping device provides that contaminants (50) that reach the wiping section (40a) are wiped off at this location and cannot move further through the bearing plate (3) to the bearing (2) that is arranged outside of the bearing plate (3).
Claims18
A bearing arrangement (1) of a compacting, perforating or cutting device for objects (200) to be processed, the bearing arrangement comprising:
- at least one processing shaft (40) that rotates about a rotation axis;
- an axially fixed or an axially floating shaft bearing (2),
- a bearing plate (3) on whose outside (3a) the shaft bearing (2) is attached directly or at a distance therefrom, and
- a splashguard wall (4) inside (3b) of the bearing plate (3) and at a distance (5) from the bearing plate (3),
- wherein the bearing plate (3) and the splashguard wall (4) respectively include a passthrough opening (13, 14) for said processing shaft (40),
- wherein a wiping device (6) with a flat plate-shaped wiper (7) is arranged in between the bearing plate (3) and the splashguard wall (4) configured to wipe contaminants from a wiping section (40a) of the processing shaft (40) extending through the distance or from a shaft portion annular disc (17) that is non-rotatably attached on the shaft, and
- wherein a wiper edge (7a) is configured as a front end of a wiper protrusion that is formed at an acute angle, and the flat plate-shaped wiper (7) contacts with the wiper edge (7a) in the wiping section (40a).
A compacting, perforating, or cutting device comprising:
- at least one processing shaft (40) that is rotatably supported by at least one bearing arrangement (1), wherein the bearing arrangement comprises an axially fixed or an axially floating shaft bearing (2), a bearing plate (3) on whose outside (3a) the shaft bearing (2) is attached directly or at a distance therefrom, and a splashguard wall (4) inside (3b) of the bearing plate (3) and at a distance (5) from the bearing plate (3),
- wherein the bearing plate (3) and the splashguard wall (4) respectively include a passthrough opening (13, 14) for said processing shaft (40),
- wherein a wiping device (6) with a flat plate-shaped wiper (7) is arranged in between the bearing plate (3) and the splashguard wall (4) configured to wipe contaminants from a wiping section (40a) of the processing shaft (40) extending through the distance or from a shaft portion annular disc (17) that is non-rotatably attached on the shaft, and
- wherein a wiper edge (7a) is configured as a front end of a wiper protrusion that is formed at an acute angle, and the flat plate-shaped wiper (7) contacts with the wiper edge (7a) in the wiping section (40a).
