EXCERPT:

SWING DEVICE

DESCRIPTION
1. The rotary group of the swing motor consists of a cylinder (24) which is integral with the drive shaft and nine piston assy (7) arranged in the cylinder bores. The cylinder (24) is supported by bearings (3) (22) on both ends.
Each piston assy (7) is guided by a return plate (6) and retaining spring (4) so as to slide smoothly on the cam plate (5).
The balance plate (21) is forced against the end of the cylinder by the force of the disc spring (18) and the hydraulic force acting on the bushing (20).
A mechanical brake is installed between the cylinder exterior and the housing (25).
A relief valve to cushion hydraulic shock and a backup valve to prevent cavitation are built in to the cover (32).
2. The reduction gear system consists of two stage planetary gears. The system decelerates high-speed rotary motion of the swing motor and coverts it to low-speed large-torque motion in order to rotate the pinion shaft.
