What is a VEE Slew Drive?
The VEE Series slewing drive adopts a cage-type base and a dual-framework oil seal design, minimizing maintenance frequency to the greatest extent possible. Customized VEE Series can be mounted directly onto the client's tracking system, effectively reducing the overall cost of the tracking system while saving installation time and boosting efficiency. Thanks to its multi-point linkage design, a single motor can simultaneously drive 2 to 3 rows of main beams; furthermore, its universal joint connection design allows for maximum savings on support structure costs, even in complex terrain environments. The VEE Series slewing drive boasts high tracking precision and exceptional resistance to wind loads. Its specialized design ensures a service life exceeding 25 years.
Key Features of a VEE Slew Drive
The VEE Series is packed with innovative features designed for longevity and extreme performance:
Enhanced Protection: Features a cage-style base and a dual-framework oil seal, achieving an ingress protection rating of up to IP65, shielding internal components from dust and water.
High Corrosion Resistance: Specialized surface treatments allow these drives to achieve a corrosion resistance rating of up to C4, ensuring reliable operation in harsh environments.
Versatile Output Options: To meet diverse engineering needs, output options include square flange, hexagonal or octagonal flange, and circular flange.
Mechanical Hard-Stop: An integrated mechanical hard-stop design provides effective protection for solar tracking systems during extreme weather conditions.
Flexible Power Input: The slewing drive can be powered by a DC motor, an AC motor, or a mechanical drive mechanism.
Customization: Customizable mounting dimensions and input interfaces are available to fit specific project requirements.
Advantages of VEE Slew Drive
The VEE Series offers significant competitive advantages for large-scale solar and industrial projects:
Significant Cost Savings: By utilizing a multi-point linkage and universal joint design, the system reduces the number of required motors and simplifies the support structure. This leads to a lower initial capital investment and reduced structural material costs.
Ultra-Low Maintenance Requirement: The combination of a cage-type base and advanced sealing technology ensures the drive remains lubricated and protected from the elements. This minimizes the need for site visits and long-term operational expenses (OPEX).
Exceptional Terrain Versatility: Unlike standard drives that require flat land, the VEE series excels in complex terrains. Its flexible connection design allows it to adapt to uneven slopes without compromising tracking accuracy or structural integrity.
Enhanced System Safety: With a service life of over 25 years and built-in mechanical hard-stops, the VEE series provides a reliable "set-and-forget" solution that protects the entire tracking array against sudden wind gusts and extreme weather.
How Does a VEE Slew Drive Work?
The VEE Series operates on the principle of high-ratio gear reduction. The input power rotates an internal gear system that engages with the main slewing ring. What sets the VEE Series apart is its mechanical flexibility; the universal joint connection design allows it to operate efficiently even when the support structures are on uneven ground. When integrated into a tracking system, the multi-point linkage allows the torque from one motor to be distributed across multiple rows of solar panels, synchronizing their movement with high precision while withstanding significant wind pressure.
Applications of VEE Slew Drives
While versatile, the VEE Series is primarily optimized for high-demand tracking environments:
Solar Tracking Systems: Ideal for horizontal single-axis and dual-axis solar trackers, maximizing energy harvest through precise orientation.
Concentrated Solar Power (CSP): Used to position heliostat mirrors that require extreme resistance to environmental forces.
Industrial Automation: Suitable for heavy-duty positioning platforms that require a low-maintenance, long-life solution.
Complex Terrain Installations: Perfect for solar farms located on hilly or irregular land where support structure costs must be minimized.
How to Install and Maintain a VEE Slew Drive
Installation:
The VEE Series is designed for rapid deployment. Because it can be customized to mount directly onto the client's existing tracking framework, it eliminates the need for complex intermediate adapters. During installation, it is crucial to ensure that the universal joints are correctly seated and that all flange bolts are tightened to the specified torque to handle the designed wind loads.
Maintenance:
The dual-framework oil seal and cage-type base are specifically engineered to minimize maintenance. This design prevents lubricant leakage and keeps abrasive contaminants out. Consequently, the maintenance frequency is reduced to the greatest extent possible, usually requiring only periodic visual inspections and long-interval lubrication checks, significantly lowering long-term operational costs.
Price of a VEE Slew Drive
The cost of a VEE Series Slew Drive is determined by several technical factors:
Customization Level: Bespoke mounting flanges and specific input interfaces for motors.
Scale of the System: The number of linkage points and the required torque for driving multiple rows.
Material and Precision: The specific accuracy class and specialized coatings for C4 corrosion resistance.
