Device for noise-testing of ball bearing in flexible assembly system in vehicle, has load unit for transmitting load to radial bearing, such that real load of radial bearing is simulated using operating conditions
The device has a frame-fixed retainer (2) for retaining a radial bearing (3), and a drive unit (6) for acceleration of a bearing part of the radial bearing. An acceleration sensor (16) detects vibration of the radial bearing at another bearing part, which is fixedly clamped in the retainer. A load u...

Abstract | The device has a frame-fixed retainer (2) for retaining a radial bearing (3), and a drive unit (6) for acceleration of a bearing part of the radial bearing. An acceleration sensor (16) detects vibration of the radial bearing at another bearing part, which is fixedly clamped in the retainer. A load unit transmits load to the radial bearing, such that real load of the radial bearing is simulated using operating conditions. The load unit includes a radial pneumatic piston acting on a wheel bearing of a vehicle and an axial pneumatic piston acting on the radial bearing.
Die Erfindung betrifft eine Vorrichtung zur Geräuschprüfung von Radiallagern. Gattungsgemäße Vorrichtungen umfassen eine gestellfeste Aufnahme für das Radiallager, in der ein erstes Lagerteil des Radiallagers fest eingespannt ist, eine Antriebseinrichtung zur Beschleunigung eines zweiten Lagerteils und einem Sensor zur Erfassung der Schwingungen des Radiallagers am ersten Lagerteil. Erfindungsgemäß umfasst die Vorrichtung mindestens eine Belastungseinheit zur Krafteinleitung auf das Radiallager, wobei die Krafteinleitung eine reale Beanspruchung des Radiallagers unter Einbaubedingungen simuliert. |
