A slew bearing system includes a first bearing ring and a second bearing ring concentrically positioned relative to each other forming at least upper and lower raceways there between, a plurality of bearing rollers positioned in each raceway between the first bearing ring and the second bearing ring, a plurality of delivery nozzles capable of delivering an air and oil mixture into the raceways adjacent the upper raceway, passages capable of fluidly communicating the air and oil mixture through the raceways and collecting some oil from the mixture adjacent the lower raceway, seals capable of regulating air flow through the passages and inhibiting outflow of oil from the raceways, and at least one exit port capable of outward flow of air and oil from the raceways adjacent the lower raceway.

A GNC device for use with a projectile, includes a rotating GNC portion and a non- rotating GNC portion, the rotating GNC portion being fixedly coupled to a projectile body, at least one bearing being interposed between the rotating GNC portion and a non-rotating GNC portion, the at least one bearing permitting the rotating GNC portion to rotate with respect to the non-rotating GNC portion. In a GNC device for use with a projectile, a method is further included.

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.

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.
摘要:
Lageranordnung umfassend eine Welle, die in zwei an Lagerböcken angeordneten Wälzlagern, von denen ein erstes als Festlager ausgeführt ist, drehgelagert ist, wobei das zweite Wälzlager (4) wenigstens eine von einer elastischen Membran (14) radial nach außen begrenzte, mit einem Druckmedium befüllbare Druckkammer (12) aufweist, welche Membran (14) sich bei in der Druckkammer (12) anstehendem Druck radial nach außen wölbt und sich bei fehlendem Druck elastisch zurückformt, derart, dass das Wälzlager (4) in einem Lagerbock (6) zur axialen Fixierung verklemmbar und im nicht geklemmten Zustand axial beweglich ist, wobei der Druckkammer (12) eine Einrichtung (22) zur Erhöhung des Drucks des zugeführten Druckmediums vorgeschaltet ist.
