Vertical Worm Gear Slewing Drive Strong Torque For Solar Panel
Tracking System
Worm Gear Slewing Drive Description
We are good supplier of slewing drives. Slew drive for solar
tracker is widely used in solar photovoltaic power generation
tracking system and other new energy industries at home and abroad
because of its multi-teeth contact, large transmission torque and
smooth operation, and it can withstand large radial and axial loads
and strong overturning moment (wind resistance). 
Slewing drive is a main part in solar tracker. By adopting slewing
bearing as its core component, slewing drive can bear axial force,
radial force and tilting moment simultaneously. There are 10
different sizes available from 3" to 25" inch.

Advantages
1. Strong overturning moment based on slewing ring
2. Adopt enveloping worm drive
3. Drive larger load for using multi tooth contact
4. Better static self-locking function
Application
Typical slew drive applications include solar industry, truck
cranes, man lifts, utility equipment, hydraulic attachments, oil
tool equipment, marine cranes, tire handlers, digger s and
automotive lifts, but the slew drives are used in many other
applications requiring load holding and rotational capability.
