PLANETARY GEAR TRAIN

摘要

FIELD: mechanical engineering. SUBSTANCE: drive sun gear of planetary gear train has involute external teeth. Low-speed sun gear wheel has non-involute teeth-webs with rounded-off areas at points of connection of webs with teeth. Fixed sun gear wheel has internal stubbed teeth. Satellite with axles are mounted on bearing ring which consists of three rings; two rings have lesser thickness and larger diameter. EFFECT: increased load-bearing capacity and reduced backlash. 1 dwg
