FIELD: machine building.
SUBSTANCE: invention relates to structural elements of planetary transmission. Cast integral structural element comprises carrier (2) of planetary gear and arranged coaxially on carrier (2) of planetary gear hollow cast hollow shaft (3). Free space (4) of hollow shaft (3) is accessible through hole (5) on at least one axial end (6) of hollow shaft (3). Hollow shaft (3) on its outer perimeter has at least one connecting element (7), which is suitable to form connection shaft hub. Planetary transmission comprises a side wall, on which there is a shaft, and cross sections of cast thinner on hollow shaft, than adjacent side wall of carrier.
EFFECT: increased mechanical reliability and transmission of higher torque.
