Enclosed Housing 5 Inch Worm Gear Slewing Drive For Solar Tracking
System And Satellite
Worm Gear Slewing Drive Description
The slew drive is an upgraded product of slew bearings, which is
usually composed of worm, turbo-type slew bearings, housing and
power resource. Housing which use high-quality cast steel has a
very high strength, worm gear uses 42CrMo and glow ion nitriding,
its wear resistance strength is higher, hardness stronger and
service life longer compared to the domestic traditional gas
nitriding 50Mn material, and other domestic envelope worm. In the
actual operation process, the slewing drive, as a transmission
bearing component, has to bear great axial force, radial force and
overturning moment. In order to meet the requirements of use, the
solar thermal slewing drive needs to ensure sufficient strength and
rigidity while having extremely high slewing accuracy.
