ROTARY DRIVE SYSTEM AND HYDRAULIC EXCAVATOR
A rotary drive system includes an electric motor, a speed reducer, and a lubricating oil-circulating unit. The electric motor has an electric motor casing forming a first accommodating space and a communication hole communicating downward. The speed reducer has a speed reducer casing forming a second accommodating space communicating with the first accommodating space through the communication hole. The lubricating oil-circulating unit has a lubricating oil flow path and a lubricating oil pump. The lubricating oil flow path connects the first accommodating space and the second accommodating space at the outside. The lubricating oil pump pumps lubricating oil from the second accommodating space side to the first accommodating space side.
