Patent ID: 8887898

Claim:
A conveyor roller ( 10 ), comprising a covering element ( 20 ), an axle element ( 40 ), and a magnetic brake ( 50 ) having a magnetic component ( 51 ) and a braking component ( 54 ) corresponding to the magnetic component ( 51 ), the covering element ( 20 ) being rotatably supported about an axis of rotation relative to the axle element ( 40 ), the magnetic brake ( 50 ) being kinematically provided between the axle element ( 40 ) and the covering element ( 20 ) and being connected to the axle element ( 40 ) and the covering element ( 20 ) such that a rotation of the covering element ( 20 ) about the axis of rotation can be retarded by the magnetic brake ( 50 ), wherein the magnetic component ( 51 ) and the braking component ( 54 ) are arranged displaceably relative to each other between a rest position and a braking position, and wherein further a centrifugal device ( 60 ) for a rotational speed-dependent displacement of at least one of the magnetic brake components ( 51 , 54 ) is provided between the rest position and the braking position, and a gearing ( 70 ) arranged within the conveyor roller so that a relative rotary movement between the covering element ( 20 ) and the axle element ( 40 ) can be converted via the gearing ( 70 ) into a rotary driving motion of a brake drive ( 55 ) of the magnetic brake ( 50 ).
