    摘要: The invention provides a bearing failure indication arrangement comprising a bearing having an inner and outer race, a first part arranged to be attached in fixed relation to either the bearing inner race or bearing outer race, a failure indicator arranged in fixed relation to both the first part and either the bearing inner race or the bearing outer race, the failure indicator constructed so that if relative movement occurs between the first part and the bearing race to which it is attached, the failure indicator responds to the relative movement thereby indicating failure of the bearing. The failure indicator is particularly adapted for use in aircraft structures and indicates full of partial bearing failure by means of movement and/or deformation of the indicator.

    摘要: The invention relates to a rolling bearing (1) having a braking device, particularly a rotational connection, comprising an outer bearing race (2) and an inner bearing race (3) between which rolling bodies are in rolling motion on associated tracks, wherein, in order to produce a braking effect using frictional engagement, a displaceable braking element connected to one of the bearing races (3, 2) is pressed against a counter surface connected to the associated other bearing race (2, 3) and said frictional engagement may be removed with the aid of an electromagnet. According to the invention, the braking element (8) is disposed as an integral bearing component inside one of the bearing races (3, 2) and pressed against the counter surface by spring force, and the electromagnet comprises one of the bearing races (3, 2) as the soft iron core and a coil (8.5) surrounding said soft iron core.

    摘要: In a bearing unit (10), at least one sensor device (20, 21) is locked in a recess (16, 17) formed in a superficial zone of one of the races (11, 12). The stationary race (11) is partially covered with an electrically insulating material (30). An uncovered surface zone (32) is provided for electrically connecting the stationary race (11) to an electrical supply source located outside the bearing unit.
