Turning speed reducer for the turntable of an excavator
A shovel includes a turning drive unit. The turning drive unit includes a turning electric motor, a turning speed reducer configured to transmit the rotational driving force of the turning electric motor to a turnable body, and a brake unit configured to maintain the turnable body in a state where the turning of the turnable body is stopped. The turning speed reducer includes a planetary speed reducer including a planetary carrier. The planetary carrier includes an output shaft part that forms an output shaft and a carrier part that holds a planetary gear in such a manner as to allow the rotation of the planetary gear. The output shaft part and the carrier part are fastened by a fastening member.
