Abstract (en)
[origin: WO2021043630A1] The invention relates to a sealing device (100) for sealing the intermediate space between a housing (200) and a shaft (310) rotatably mounted in the housing, having a first plate-shaped body (110) with a front face, a rear face, and a first opening (120), which extends from the front face to the rear face and is suitable for feeding through the shaft (310), and having a cooling line (170), which runs in the body (110) and is suitable for conducting a cooling medium. The first body (110) is suitable for being tightly secured to the housing (200) such that the shaft (310) rotatably mounted in the housing (200) is guided through the first opening (120). The first opening (120) is suitable for introducing sealant (140) such that the sealant (140) seals an intermediate space between the shaft (310) and the first body (110). The cooling line (170) is guided around the first opening (120) between a cooling line inlet (172) and a cooling line outlet (174) for the cooling medium such that heat produced from rotating the shaft (310) can be dissipated by the cooling medium in a spatially homogenous manner.
