Abstract:
The invention relates to a hysteresis coupling or brake, comprising a drive part 1 which is equipped with an annular hysteresis material 6 and a driven part 7 which is concentrically arranged in relation to the drive part 1 and equipped with permanent magnets 28, wherein between the hysteresis material 6 and the permanent magnet 28 an annular air gap 47 is formed and the drive part 1 is designed as a crucible-shaped flange. The rolling bearing 30 is fastened to the inner wall 3 of said flange, and the permanent magnets 28 and the hysteresis material 6 are arranged radially outside of the rolling bearing 30. The hysteresis coupling or brake is completely or partially surrounded and thus the space between the permanent magnets and the hysteresis material is sealed by rotary shaft seals or gap seals and is protected against influences from the outside.
