• Outer ring and inner ring: The basic structure of the SE series slew drive consists of an outer large ring and an inner small ring. An annular space is formed between these two rings in which the rotational motion takes place. The outer ring is fixed in the mechanical system, while the inner ring is connected to the mechanical equipment and rotates through the drive system.
• Gear system: The gear system between the inner and outer rings is the key transmission mechanism. The gear system consists of precision-made gears that allow the inner ring to rotate smoothly relative to the outer ring. The design and manufacture of gears is critical to ensuring the accuracy, torque transfer and durability of the system.
• Motor: The motor is the power source of the SE series slew drive, and a high-efficiency DC or AC motor is usually selected. The output shaft of the motor is connected to the gear system to drive the rotary motion by providing rotational torque.
• Reducer: In order to reduce the high-speed rotational motion output by the motor, SE series slew drives are usually equipped with a reducer. Reducers increase torque by slowing down rotation and ensure smoothness and precision of the system.
