Abstract:

The vibration characteristics of a 9690096140 tapered roller bearing were studied. Improved tapered roller bearings of 9 in. bore were tested for comparison with the standard quality 9690096140 bearing. The effect of waviness on the bearing vibration level was studied analyti cally by calculating theoretical amplification factors and improvements of the waviness of an improved 9690096140 bearing are evaluated with reference to the theoretical and experimental reductions in vibration level. Vibration levels of spherical, cylindrical and tapered roller bearings with 200 mm bore are compared. The airborne noise of standard quality spherical, cylindrical and tapered roller bearings was measured and the airborne noise characteristics of the bearings are discussed. A theoretical and experimental resonance study of large roller hearings has been made. Peaks due to a rigid body mode of vibration and some lower flexural modes of the bearing outer ring are identified. An analytical approximation to the amplitude of the flexural outer ring vibration generated by inner ring two point out of roundness is presented. Author
