High Precision ZSE7 Solar Slewing Drives With Planetary Gear Motor For PV Trackers
High Precision Slewing Drive Description
Backlash – the existing clearance gaps between gear teeth and worm is a very common and often a considerable and key factor in the designs of gear and drive systems. The gaps between them allow room for applying lubrication and can help accommodate the stresses of operation heat inside.
The gear and worm are contact in a condition of near perfect mesh. This will in turn allows for a highly efficient transfer of driving force, uniform load distribution and a very impressive level of positioning accuracy in drive
Our slewing gearboxes have proved well performed under extreme operating conditions. We provided slew drives with cost savings from standard parts, reduced lead times, tested and proven designs across the whole range and readily available spares for units in service especially in mass production.

Applications Need High Precision
Parabolic trough solar power system:
Parabolic trough solar collector is mainly composed of concentrated part, transmission system, heating unit and control system, adopts columnar parabolic design, tracking the sun through parabolic trough concentrate collector, make direct sunlight gathered in receiver tube surface, to heat the heat-transfer fluid, and then in thermodynamic cycle system. In the thermodynamic system, Parabolic trough concentrating collectors are connected by way of series and parallel, and through the modular layout form collection hot field.
