Abstract:
A bearing arrangement, comprising:a movable shaft coupling having a first coupling half, the coupling half including a coupling journal and a first geometric central axis, the coupling journal including a ball joint arranged fixedly relative to the coupling journal, the ball joint being arranged fixedly relative to the first coupling half and relative to the first geometric central axis; a second coupling half having two parallel counter-extending faces and a third central axis; a radial rolling bearing having a geometric bearing axis and rolling bodies; a running roller arranged on the coupling journal, the running roller including a second geometric central axis, a first running face arranged concentrically to the second geometric central axis and configured for torque-transmitting engagement with one of the two parallel counter-extending faces, a second running face for engagement with the rolling bodies, an outer circumference and an inner circumference, the outer circumference being one of integral with and fixedly connected to the first running face, the inner circumference being one of integral with and fixedly connected to the second running face, the geometric bearing axis being arranged coaxially to the second geometric central axis, the second running face defining an outer running face relative to the radial rolling bearing; the radial rolling bearing including a sleeve-shaped inner ring having a third running face to which the rolling bodies are immovably fixed in a direction of the geometric bearing axis, the third running face defining an inner running face relative to the radial rolling bearing, the sleeve-shaped inner ring being arranged concentrically to the geometric bearing axis, the sleeve-shaped inner ring being connected to the coupling journal via the ball joint; a first arrangement configured to maintain a position of a joint center of the ball joint relative to the inner ring; a second arrangement to maintain an additional degree of freedom of relative movement between the coupling journal and the second coupling half in a direction transversely to the third central axis, the second arrangement including a loose bearing of the rolling bearing permitting relative movement between the running roller and the inner ring in a direction of the second geometric central axis.
