| 摘要 |
The invention relates to a bearing (56a, 56b) for mounting a rotating shaft (76) comprising a bearing housing (60) with an opening for accommodating a shaft (76) to be mounted, an inwardly oriented peripheral retaining collar (74) arranged on the edge of the opening, a bearing bush (58) arranged in the bearing housing (60), and a sealing ring (72) arranged in the bearing housing (60) between the bearing bush (58) and the retaining collar (74), which sealing ring abuts the rotating shaft (76) in a sealing manner. According to the invention, the sealing ring (72) has a sealing lip (72c) angled away from the bearing bush (58), oriented axially and tapering to a point at its free end, which sealing lip forms a contact surface of the sealing ring (72) on the shaft (76) to be mounted. The invention can be used in particular in conveying devices for high-density materials, e.g. in a screw conveyor, in which the sealing of the bearing is to be guaranteed against a conveyed medium penetrating from outside. |
