DYNAMICAL BEARING UNIT Russian patent published in 1995 - IPC

FIELD: machine-tool engineering. SUBSTANCE: unit has shaft, e.g., spindle 1, set in front and rear supports inside housing 2. The front support consists of bearings 3 and 4. Hollow ring 6 is set in a bore of housing 2 covered with flange 5. Bearings 3 and 4 are received in the hollow ring. Ring projection 7 made on rear face wall 8 abuts against the face of the housing bore. Inner and outer ring projections made on the front face wall of the hollow ring abut against flange 5. Small radial beams provided with displacement pickups, e.g. strain gauges, are equidistantly arranged over periphery. Wall 8 goes into internal flange 15. The outer ring of bearing 4 abuts against the flange. EFFECT: enhanced reliability. 5 dwg
