Industrial Cast Iron Planetary Gear Reducers Planetary Gear Box

Product Description

Planetary gear reducer gearbox have been designed for different transmission .The power is transmitted from the motor to sun gearboxes. The sun gearbox drives three Planetary Gearboxes, which are contained within an internal toothed ring gearbox. Planetary Gearboxes are mounted on the planetary carrier. The planetary carrier is part output shaft. when the sun gearbox rotates, it drives the three Planetary Gearboxes inside the ring gearboxes. As worm planetary gear reducer gearboxrotate with carries and automatically the highest torque and stiffness for a given envelope. 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 the planetary-type gearbox truly ideal for servo applications.
