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°.
