Axis of input and output is located on concentricity
Consistent direction of rotation of axis on input & output
Transmit power per volume is excellent
High capacity, compact sized, lightweight
Effective transmit power due to only small friction loss
Can be applied to various kind of valves
Sambo Planetary Gears Application:
Dual Speed Input Gear Box can make Valve & Valve Gear box’ s actuator operating time (operating speed) higher by reducing the total number of turns.
Switching between the two ratios is done by simply pushing or pulling on the input shaft. The high ratio gearing is used for the portion of the valve stroke where the torque requirement is high to initially open a valve or the last cycles to close it.
During travel the valve torque usually drops considerably and the lower ratio can be employed to reduce the number of input turns required.
