SE3/SDE3 slew worm drive system is a compactly constructed unit which consists of a slewing ring, base plate and worm. This unit brings the advantages of a slewing ring and a worm into one unit.
It is suitable for applications which demand slow rotation with a continuous or cyclical movement capable of handling combined loads. The product is with standard dimensions for coupling an electric or hydraulic motor as well as coupling a whole system to equipment.
Due to its compactness, high rigidity and other mentioned advantages, a worm drive system is used in varying equipment such as Solar Power System, mobile assembly platforms, satellite system, hydraulic loading cranes on haulage vehicles, small marine cranes, extendable rotating ladders, in wheel units of large marine portal transporters.
Some Data Explaination:
1)Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the torque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
2) Radial load: Load vertical to the axis of slewing bearing.
3) Axial load: Load parallel to the axis of slewing bearing.
4) Holding torque: It is the reverse torque. When the drive is rotating reversely, and parts are not damaged.
5) The maximum torque achieved is called holding torque.
6) Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.
