The bearing parallel misalignment running model–based

Jun 04, 2018· The radial clearance between the rings was assumed to move the shaft along the radial direction without shaft tilt; therefore, parallel misalignment of the bearing induced an additional radial displacement for each ball δ r cosψ j with respect to the initial position. When the cutting force was applied to the bearing, the ball gained an additional radial displacement δ ′ r …
