FIELD: mechanical engineering. SUBSTANCE: proposed planetary gear train contains central wheels, carrier and plant pinions installed on shaft by means of compensating unit. Compensating unit is made in form of ball bearing with two projections, bushings with guide beans and set of races with larger and smaller diameter of section made of elastic material and placed in turn between hole of inner race of ball bearing and outer surface of bushings. EFFECT: improved reliability and increased service life of planetary gear train owing to reduction of vibration activity and equalizing load on length of pressure lines of planet pinion-to-central wheel meshing and between planet pinions at small axial dimensions of planet pinion unit. 2 dwg |
