DYNAMIC BEARING UNIT Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: dynamic bearing unit has resilient ring with circumferentially equally spaced single-support L-shaped beams, which are disposed at one end of resilient ring. Beams are made L-shaped in radial section and are provided with motion detectors. Free ends of beams extend beyond secured end of ring. Resilient ring is mounted between bearing fixed ring, with bearing resisting radial and axial loadings, and fixed part of dynamic bearing unit. Each beam has protrusion extending at side opposite to its free end. Protrusion does not reach of other end of ring for a value determined by measurement range. Protrusion is radially spaced from free end at beam for a distance, which together with above mentioned value is determined by primary measurement range. It allows changing from one measurement range to other measurement range to be provided. Second additional ring similar to first one is immovably secured to first ring to increase measurement sensitivity and to facilitate changing from one measurement range to the other measurement range. Free ends of beams of rings are oriented in opposite directions. Planes of symmetry of beams of both rings coincide one with the other. Protrusions of beams are disposed one opposite the other to define space between them. EFFECT: wider operational capabilities and enhanced reliability in operation. 3 cl, 11 dwg
