Swing Reduction Gear
GENERAL DESCRIPTION
Theory of Operation
The swing motor final drive is a two-stage planetary gearbox
with two planet gears, two sun gears and two-stage output
reduction. The planetary gear engages the ring gear. The pinion
gear is connected to the output shaft and spline.
The final drive reduces swing motor rpm to increase swing motor
output torque. The available maximum swing speed provides a
fast turning rate for efficient, rapid work cycling with more than
adequate power for good acceleration.

SHRINKAGE FITTING OF SHAFT
AND FLEXIBLE BEARING
1. Washing of shaft
Remove fluids like anticorrosive fluid applied to the shaft
and use an air conditioner to remove foreign substances.
2. Insert the support plate and the NILOS ring into the
prepared shaft as shown in the figure and heat bearings
(#22314, 2109-1041) on the heater.

3. When bearing is heated up to 90°C - 100°C, remove it from
the heater, hold it with both hands, and insert it into the
shaft evenly.
To do so, slowly insert bearing 4-5 mm that it seats itself
and then push it strongly to contact the NILOS ring.
4. After assembling the bearing, let it cooled fully in the air for
1 to 2 hours.
