IP66 Enveloping Worm Gear Transmission, C5 Corrosion Class For Solar Tracking Systems
Enveloping Worm Gear Slew Drive Description
A slewing bearing or slew ring drive is a rotational rolling-element bearing that can typically supports a heavy load but slow-turning.
The slewing drive's application is extensive and has increased significantly. Once primarily utilized for mining and heavy construction, now slewing drive applications include solar energy, wind turbines and even amusement rides. Industries turn to slew drives that require tremendous strength, accuracy, safety, and efficiency.

Features
1. Can get a large transmission ratio
2. More compact design
3. More tooth contact by using envelop worm, the multi-tooth meshing transmission make it running smoothly with low noise.
4. Self-locking, it can realize the reverse self-locking, that is to say, only the worm to drive the worm wheel. With this feature, the worm mechanism used in heavy machinery can play a safety protection role.
5. High transmission efficiency, less wear.
Applications
Engineering machinery is the most widely used place for slewing bearings, such as Earth moving machinery, excavators, disintegration machines, stacker reclaimers, graders, road rollers, powerful boring machines, rock drilling machines, etc.
