The establishment of flexible supporting thin angular contact bearing model

According to the thin wall of an aeroengine with angular contact ball bearing AC71907 as an example to analyze.

  Bearing parameters, outer diameter is 55mm, the outer ring raceway diameter is 50.586mm, the inner diameter is 35mm, the inner ring raceway diameter is 39.423mm, the ball diameter 5.556mm, the ball number 15, ( thin wall bearings )the initial contact angle of 25 deg..

  Between the bearing seat and the bearing outer ring is in interference fit, with the gap of m in 0-15um.
