Rolling bearing for rotatively mounting a machine element

摘要

The present invention relates to a rolling bearing for rotatively mounting a machine element, including a sensor for measuring a mechanical load acting on the rolling bearing. The rolling bearing can be a wheel bearing of a motor vehicle, for example, or the bearing of a gearbox shaft. The rolling bearing includes a first bearing ring and a second bearing ring, which can be rotated with respect to the first bearing ring. A bearing inner space, which has at least one first axial section in which rotatable rolling elements are arranged, is formed between the first bearing ring and the second bearing ring. The rolling bearing further includes at least one sensor for measuring a mechanical load acting on the rolling bearing, in particular for measuring a force or torque, or a physical variable derived from a force or torque, for example, angular momentum or mechanical tension.

主权项

1. A rolling bearing for rotatively mounting a machine element, comprising:
a first bearing ring including first and second halves forming respective axial ends of the first bearing ring; a second bearing ring, rotatable with respect to the first bearing ring and located radially outward of the first bearing ring; a clip holding the first and second halves of the first bearing ring together; a bearing interior, having at least one first axial section formed between the first bearing ring and the second bearing ring; first rotatable rolling elements arranged in the at least one first axial section; a first strain sensor for measuring a first mechanical load acting on the first half of the first bearing ring and arranged in a second axial section of the bearing interior; and, a second strain sensor for measuring a second mechanical load acting on the second half of the first bearing ring and located in the second axial section of the bearing ring.
