Some characteristics of rolling-element bearings under oscillating conditions. Part 3: experimental results for clearance-fitted taper-roller bearings and their relevance to the design of spindles with high dynamic stiffness
AbstractSome characteristics are presented for taper-roller bearings with a clearance fit. The stiffness and damping in the joints between raceways and housing/shaft are shown to be significant. The other major parameters investigated are preload, temperature, lubricant viscosity, excitation frequency, excitation amplitude, and rotational speed. The relevance of the measured characteristics to the design of spindles with high dynamic stiffness is discussed. Also the significance of radial and tilt characteristics is compared.

DescriptionThe Machine Tool Industry Research Association was well aware of the significance of rolling-element bearings in modern machinery when it funded confidential research into rolling-element bearings stiffness and damping characteristics under working and oscillating conditions, and the effects of rolling contacts and bearing fitment joints. The Machine Tool Industry Research Association recently gave permission for this work to be published in open literature.
