CRAWLER VEHICLE TRACK-CARRYING WHEEL Russian patent published in 2003 - IPC

FIELD: transport engineering; crawler vehicles. SUBSTANCE: proposed track-carrying wheel has roller installed on fixed shaft by means of end face and radial sliding bearings. Longitudinal channel made in center of shaft communicates through radial holes with end face sliding bearings. Oil reservoir in form of open ring space is arranged in middle part of shaft, said ring space being connected with longitudinal oil channel by radial holes. Additional holes are arranged diametrically opposite in vertical plane and are made with diameter not less than 4 mm. Longitudinal flats are made on shaft surface. EFFECT: decreased load on bearing unit owing to increase of shaft contact area at provision of intensive lubrication of friction surfaces. 2 dwg
