VH9 Technology Specification
Product Advantage
Slewing drives sit on the center axis rotation of the torque tube drive line, they can be set as close to the ground as the size of the solar panels will permit. This allows the shortest, strongest, and least expensive underlying structure to be built for supporting the solar trackers in the field, which is a considerable amount of the overall cost incurred.
Slewing drives rotate 360˚ continuously, so it’s up to the solar tracking design engineer to limit their rotation at whichever angle is desired for the particular equipment. The selection is endless. For linear actuators though the size, cost, and approvals are unwieldy for anything more than +/-45˚.
Installation of a slewing drive is simply the fastening of the main structural bolts (normally 4 fasteners). There is no sub-assembly, post qualification, lubrication, inspection, or other work required.
Slewing drives are shown to last 25-30 years in solar applications, with some models even available in a maintenance free version.

Can a Worm Gearbox be Used for High-Speed Applications?
Worm gearboxes are generally not recommended for high-speed applications due to their inherent design characteristics. Here’s why:
- Efficiency: Worm gearboxes tend to have lower efficiency compared to other gearbox types, which means they can generate more heat and experience more energy loss at high speeds.
- Heat Generation: The sliding contact between the worm and worm wheel in a worm gearbox can lead to significant friction and heat generation, especially at high speeds. This heat can cause thermal expansion, affecting the gearbox’s performance and longevity.
- Wear and Noise: High speeds can exacerbate wear and noise issues in worm gearboxes. Increased friction and wear can lead to faster degradation of components, resulting in reduced lifespan and increased maintenance needs.
- Backlash: Worm gearboxes may have higher backlash compared to other gearbox types, which can impact precision and accuracy in high-speed applications.
While worm gearboxes are more commonly used in applications requiring high torque and moderate speeds, they may not be the best choice for high-speed scenarios. If high-speed operation is a requirement, other gearbox types such as helical, spur, or planetary gearboxes are often better suited due to their higher efficiency, lower heat generation, and reduced wear at elevated speeds.
Diagnosing and Fixing Oil Leakage in a Worm Gearbox
Oil leakage in a worm gearbox can lead to reduced lubrication, increased friction, and potential damage to the gearbox components. Here’s a step-by-step process to diagnose and fix oil leakage:
- Inspect the Gearbox: Perform a visual inspection of the gearbox to identify the source of the leakage. Check for oil stains, wet spots, or oil pooling around the gearbox.
- Check Seals and Gaskets: Inspect the seals, gaskets, and O-rings for any signs of wear, cracks, or damage. These components are common points of leakage.
- Tighten Bolts and Fasteners: Ensure that all bolts, screws, and fasteners are properly tightened. Loose fasteners can create gaps that allow oil to escape.
- Replace Damaged Seals: If you find damaged seals or gaskets, replace them with new ones. Use seals that are compatible with the operating conditions and lubricant.
- Check Breather Vent: A clogged or malfunctioning breather vent can cause pressure buildup inside the gearbox, leading to leakage. Clean or replace the breather vent if necessary.
- Examine Shaft Seals: Check the shaft seals for wear or damage. If they’re worn out, replace them with seals of the appropriate size and material.
- Use Proper Lubricant: Ensure that you’re using the correct lubricant recommended for the gearbox. Using the wrong type of lubricant can cause leaks.
- Apply Sealants: In some cases, applying a suitable sealant to the joints and connections can help prevent leaks. Follow the manufacturer’s instructions for proper application.
- Monitor Leakage: After addressing the issues, monitor the gearbox for any signs of continued leakage. If leakage persists, further investigation may be required.
- Regular Maintenance: Implement a regular maintenance schedule that includes checking seals, gaskets, and other potential leakage points. Timely maintenance can prevent future leakage issues.
If you’re unsure about diagnosing or fixing oil leakage in a worm gearbox, consider consulting with a professional or gearbox manufacturer to ensure proper resolution.
Types of Worm Gear Configurations and Their Uses
Worm gear configurations vary based on the arrangement of the worm and the gear it engages with. Here are common types and their applications:
- Single Enveloping Worm Gear: This configuration offers high torque transmission and efficiency. It’s used in heavy-duty applications like mining equipment and industrial machinery.
- Double Enveloping Worm Gear: With increased contact area, this type provides higher load capacity and improved efficiency. It’s used in aerospace applications, robotics, and precision machinery.
- Non-Throated Worm Gear: This type has a cylindrical worm without a throat. It’s suitable for applications requiring precise motion control, such as CNC machines and robotics.
- Throated Worm Gear: Featuring a throat in the worm, this configuration offers smooth engagement and higher load capacity. It’s used in conveyors, elevators, and automotive applications.
- Non-Modular Worm Gear: In this design, the worm and gear are a matched set, resulting in better meshing and efficiency. It’s utilized in various industries where customization is essential.
- Modular Worm Gear: This type allows interchangeability of worm and gear components, providing flexibility in design and maintenance. It’s commonly used in conveyors, mixers, and material handling systems.
Selecting the appropriate worm gear configuration depends on factors such as load capacity, efficiency, precision, and application requirements. Consulting gearbox experts can help determine the best configuration for your specific needs.
