VE7 Self Lock Worm Gear Slew Drive For Solar Tracking System
Worm Gear Slewing Drive Description
The power generation of the dual-axis tracking system using the SDE
series slewing drive device is the highest, followed by the
inclined single-axis and flat single-axis, and the power generation
gains of the fixed support are 23.83%, 22.89% and 11.2%,
respectively. At the same time, the power curve of the tracking
bracket is flatter than that of the fixed bracket and the flexible
bracket, and it is more friendly to the power system.
Located in high latitude areas, the cumulative radiation of VE
series and SE series flat uniaxial supports with inclined angles
and flat uniaxial supports with 5° and 10° inclined angles has
obvious advantages over conventional flat uniaxial supports.
Reliability: Slewing drives are designed and tested to guarantee a 30-year field life. All of the raw materials are meet the standards required by ISO9001 and CE. We implement a sound quality control to ensure out products of high quality, reliable and low cost.
Performance: slew drives are powered with hourglass worm technology to give the gearbox enormous strength and power, maximum survivability load-holding as well as increased efficiency and accuracy.
Applications: Slewing drive applications include solar
trackers, wind turbines, truck cranes, man lifts, utility
equipment, hydraulic equipment attachments, oil tool equipment,
tire handlers, digger s and automotive lifts etc
Installation: Our slewing drives could be mounted
horizontally, vertically or a combination of multiple axes.
