Rotary brake for machine construction, has housing with superficies surface in inner area and piston in outer area, which are provided with circular recesses that form opposite slit-formed segments

摘要

The brake has a cylindrical piston (1) arranged on a shaft (2) and inserted in a housing (4), where the housing is pivoted on the shaft. A gap (7) is filled with a viscous medium and outwardly sealed with appropriate sealing units (8, 9). A superficies surface of the housing in an inner area and the piston in an outer area are provided with circular recesses (1a, 4a), which form opposite slit-formed segments.
