  • Patent number: 5074677
    Abstract: A large open-center roller bearing consisting of single or multiple outer and inner rings with rollers rolling over races between the rings, wherein one ring can accommodate an ultrasonic probe and the other ring has a contact surface. The object is to provide a bearing that can be simply and reliably tested by ultrasound. One or more contact surfaces (19, 24, and 25) extend around one or more of the outer surfaces of the ring (2 or 3) being tested.

  • Patent number: 4989999
    Abstract: An empty-center rotating-roller joint with a non-segmented race (1) that has a lip (17) extending radially outward and with a U-shaped cross-section outer race (2) that encloses the lip. Two rows of rollers (11 & 12) transmit axial loads and one row (13) of rollers transmits radial loads. The rollers roll over hardened roller-contact surfaces (5, 6, 7, 8, 9, & 10) between the races. Roller-contact surfaces (8, 9, & 10) in the form of hardened wires (18, 19, and 20 ) are positioned against the lip of the non-segmented race (1) only. The contact surfaces of the lip of the non-segmented disk-shaped race can be hardened without the hardening process contributing to excess tension in the race. Furthermore, once the teeth on the race have been hardened, very little or no additional machining of the races will be necessary.
