7 Inches Worm Gear Small Slew Drives, Large Transmission Ratio For Solar Energy
Worm Gear Small Slew Drives Description
Worm gear slewing drive, also named as slewing reducer. It is commonly composed of worm, slewing bearing, housing, motor adapter, end cap and other components. By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. Comparing with SE series slewing drive, WEA series have the advantages of better protective performance, great transmission torque, better impact resistance and long working life.
Worm gear slewing drive is widely applied in the relatively rotary parts of machinery such as aerial working machinery truck crane Rock drill, drilling machine grasping wood machine, code molding machine and solar energy field such as Solar tracking system, CSP, CPV.

Applications
Slewing drives are able to withstand greater axial loads, radial loads and tilting moments. The turntable or frame is driven by a slewing drive to rotate in azimuth and elevation.
For solar energy: It is designed in a solar tracking system to increase the efficiency of power generation.
Industrial use: Mainly used to drive two objects that rotate relative to each other at 360°.
