Freewheel coupling
View Patent ↗A freewheel coupling ( 1 ) is provided having a gap ( 12 ) formed between a bearing inner ring ( 2 ) and a bearing outer ring ( 3 ). At least one of the bearing rings ( 1, 2 ) is constructed as a sleeve formed using a non-cutting method. Clamping bodies ( 6 ) are arranged in the gap ( 12 ) and have a throat ( 7 ). A spring band ( 13 ) with spring tongues ( 14 ), which are aligned tangentially, and which can be deflected in the radial direction, contact the clamping bodies ( 6 ) in the area of the throats ( 7 ). A cage ( 17 ) with recesses ( 18 ) that holds the clamping bodies ( 6 ) is arranged radially outside of the spring band ( 13 ) in the gap ( 12 ).
1. Freewheel coupling, comprising
a gap formed between a bearing inner ring and a bearing outer ring, wherein at least the bearing outer ring is constructed as a sleeve formed using a non-cutting method, the bearing outer ring including inwardly projecting rims,
clamping bodies arranged in the gap and having a throat,
a spring band with spring tongues, which are aligned tangentially, which can deflect in a radial direction, and which contact the clamping bodies in an area of the throats,
a cage with recesses for holding the clamping bodies, which is arranged radially outside of the spring band in the gap, and the cage has a contact surface for the clamping bodies loaded in the radial direction.
2. Freewheel coupling according to claim 1 , wherein the cage is made from plastic.
3. Freewheel coupling according to claim 1 , wherein the cage is spaced apart from the bearing outer ring radially at least in a load-free state.
4. Freewheel coupling according to claim 1 , wherein a recess of the cage has a first area holding the clamping body and also an area, which is adjacent to the first area in a circumferential direction, which is narrower in an axial direction, and which allows a radial deflection of the spring tongue in the direction towards the bearing outer ring.
