pöördemootor

A pöördemootor, or slewing drive, is a specialized gearbox designed to rotate a load on a horizontal axis. It typically consists of a worm screw that engages with a large-diameter ring gear. This configuration provides a high gear reduction ratio, which allows for precise control and the ability to hold loads in position without the need for external brakes. The integrated bearing system within the slewing drive supports significant axial, radial, and tilting moment loads.

Pöördemootors are commonly used in applications requiring controlled rotation and high load-holding capacity. Examples include the positioning of solar panels to track the sun, the rotation of telescope mounts, the operation of cranes and lifting equipment, antenna positioning systems, and in robotic arms. Their robust design makes them suitable for harsh environments and continuous operation.

The key components of a pöördemootor are the worm screw, the slewing ring (which contains the internal or external gear), and the motor or actuator that drives the worm screw. The motor can be electric, hydraulic, or pneumatic, depending on the specific requirements of the application. The slewing ring itself is a large bearing that provides the rotational capability and load support. The gearing mechanism ensures high torque output and precise positioning.
