SWIVEL DRIVE DEVICE FOR CONSTRUCTION MACHINERY
The present invention relates to a swivel drive device for construction machinery, and more specifically relates to a swivel drive device for construction machinery adapted to drive the swivelling of an upper body on a lower body. The swivel drive device for construction machinery according to the present invention provides a swivel drive device having an external size which is either the same as or comparable to that of a conventional swivel drive device but nevertheless is at the same time adapted to be able to increase the step-down gearing ratio and hence is adapted to improve the power output and torque. The swivel drive device for construction machinery according to the present invention makes it possible to reduce loss of energy due to hydraulic fluid during high-speed driving of the swivel drive device.
