slewing ring and slewing drive's application of solar tracking system

A solar tracking system positions various payloads―such as solar PV panels, reflectors or lenses―toward the sun. Trackers are used to maximize the amount of incoming light by following the sun as it moves across the sky. Solar trackers are categorized by the number and orientation of their axes and whether they employ fixed, single or dual axis tracking systems.

The slew drive comes in two types: single row ball and double row ball. These are selected depending on the load coming on the drive. Higher loads generally need double row slew bearing.

The slewing drives come with an IP65 rated protection system, which protects the drive from environmental conditions as well as dirt, sand, dust and even water. The drive is designed in such a way that huge loads can be carried in spite of the compact form factor. The gears used in the assembly are hardened and ground, so that they provide maximum durability and longer life.

Irrespective of whether solar tracking system are pho-tovoltaic or solar thermal plants, they are particularly efficient if the collectors track the course of the sun in the sky. The more precise and trouble-free they operate the better and more profitable the plants are.

This is where rolling and plain bearings from xuzhou wanda Slewing Bearing come in. They have high rigidity and high load carrying capacity and operate reliably even under extreme operating conditions.
