SLIDING BEARING THRUST UNIT Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: fitted in housing is shaft with flange. Disk with two ring projections is arranged on bearing surface of flange. Placed between housing and disk are self-aligning shoes engaging with disk by their working surfaces. Antifriction segments are installed on disk bearing surface. Side surfaces of antifriction segment are arranged at angle α to disk radius passing through intersection of side surface of antifriction segment with inner edge pointed to shaft. Antifriction segment are secured on disk with clearance relative to each other. Angle a of tilting of antifriction segment side surfaces is found from equation tgα>δ+C/l where δ - distance between antifriction linings on self-aligning shoes; C - distance between antifriction segments; l - width of antifriction segments in radial direction. Ring projections can divide disk bearing surface into three parts equal in radial direction. EFFECT: enlarged operating capabilities. 2 cl, 5 dwg
