Worm Gear Slewing Drive Description


As technology has improved, more slewing drives are using hourglass worm technology, in which the worm is shaped to engage more teeth in the gear, thus the torque imporved and the backlash decreased. 


SE3 Worm Gear Envelope Slew Drive Gearbox IP66 Protection 0

This increased tooth engagement results in greater strength, efficiency and durability.The slewing drive uses standard worm technology in which the worm on the horizontal, the speed ratio of the shaft depends on the relationship between the number of threads on the worm and the number of teeth in the worm gear.

Installation of the Slew Drive


1.Clean the mounting structure, e.g. from welding, galvanizing, residues, dirt, etc.

2.Lift the slew drive with eye bolts.

3.The slew drive shall be mounted in unloaded condition.

4.The following procedure shall be followed in order to avoid deviations between bolt tightening forces.

5.Apply thread lock liquid to threads.

6.Lay thread lock liquid on thread gap requesting fitting parts fully.

7.Preload the bolts crosswise. See the general pattern in sketch below of how bolts get torque in crosswise sequence. Start with either inner or outer ring. Do the crosswise torqueing of all bolts to 30% of tightening torque. Then repeat crosswise torque to 80% of tightening torque. Finally crosswise torque to 100% of the tightening torque.


There are many applications where a rotary drive can be used, primary because it is well suited for applications that require load to maintain power and rotational torque.
Typical swing drive applications include, but are not limited to:
1.Solar tracker
2.Wind Turbines
3.Men's lift
4.Hydraulic machinery
9.Drilling equipment
10.Military equipment
