  • Bearing arrangement
    Patent number: 8100587
    Abstract: An outer ring for a rolling element bearing has three mounting pads on its outer surface. The inner surface of the ring is arranged to be non-circular, with its effective radius being at a minimum at the three points midway between adjacent pairs of mounting pads. This provides a preload on the rolling elements of the bearing in use, preventing skidding, but because the ring is not supported between the pads it can still flex under loads. The ring may be oriented in use so that transient loads are directed through one of the mounting pads.
    Type: Grant
