Load-measuring bearing unit

摘要

A bearing unit (20) for measuring forces exerted on the bearing unit, comprising an inner member (3) concentrically arranged around an outer member (2), at least one rolling element bearing (4, 5) and at least one load measuring device (8, 9) with a cylindrical bore. The load measuring device (8, 9) is mounted to one of the members (3) and supports the rolling element bearing (4, 5) relatively to this member (3). The rolling element bearing (4, 5) is mounted to the other of the members (2) and supports this member (2) relatively to the load measuring device (8, 9). Thus, a force acting on the bearing unit is transferred from one of the inner and outer members (2, 3) to the other of the inner and outer members (2, 3) via the at least one load measuring device (8, 9). According to the invention, the at least one load measuring device (8, 9) and the at least one rolling element bearing (4, 5) are arranged laterally to each other in a radial gap between the inner and outer members (2, 3).

主权项

1. A bearing unit comprising an outer member concentrically arranged around an inner member, a first rolling element bearing and a first load measuring device with a bore, wherein:
the first load measuring device is mounted to one of the members and supports the first rolling element bearing relatively to this one of the members; wherein the first rolling element bearing is mounted to the other of the members and supports this other of the members relatively to the first load measuring device, the first rolling element bearing comprising a first ring, a second ring, and rolling elements arranged between the first and second rings; wherein the first load measuring device and the first rolling element bearing are arranged laterally to each other in a radial gap between the inner and outer members; wherein the first load measuring device is not disposed radially between the first ring and the one of the members to which the first load measuring device is mounted; and wherein: the first rolling element bearing comprises a flange coupled with the first ring, wherein the flange is mounted to a radial side face of the first load measuring device.
