GBX-Series Gearbox

Gearboxes

The GBX servo gearbox family is designed for direct connection to ORMEC servomotors. It is a high precision, low backlash servo gearbox for industrial motion control applications.

The GBX-AB-Series and the cost effective GBX-AE-Series are helical planetary gearboxes. They are designed for continuous (S1) or cyclic (S5) duty operation. Both the GBX-AB and GBX-AE families have inline shafts and right angle models.

Delivery from stock in two weeks.

*The APEX servo gearboxes are designed for direct attachment to popular servomotors. The power is transmitted from the motor to sun gear. The sun gear drives three planet gears, which are contained within an internal toothed ring gear. The planet gears are mounted on the planet carrier with double wall supports. The planet carrier is part output shaft. When the sun gear rotates, it drives the three planet gears inside the ring gear, and as the planet gears rotate automatically the output shaft rotates.

Due to the load sharing into multiple tooth contacts, the planetary gearbox (gear heads) provides the highest torque and stiffness for a given envelope. The other significant advantages are simple and efficient lubrication and a balanced system at high speeds. The balanced planetary kinematics and the associated load sharing make planetary-type gearboxes ideal for servo applications.
