Product Description
Coresun Drive slewing drive gear motor worm drive for horizontal single-axis solar tracking system. For horizontal single-axis solar tracking system, the main shaft of solar panel will adjust the angle to precisely track the declination angle. This kind of slewing drive is only applied for low latitudes area.
Slew Drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new slewing drive features easy installation, easy maintenance and a greater degree of installation space.
Slew Drive are widely used in PV,CPV,STP solar tracking systems and construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind power systems and satellite communications.
Glossary
Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the qorque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
Radial load: Load vertical to the axis of slewing bearing
Axial load: Load parallel to the axis of slewing bearing
Holding torque:It is the reverse torque.When the drive is rotating reversely, and parts are not damaged,The maximum torque achieved is called holding torque.
Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-loc

Common Problems and Troubleshooting for Worm Gearboxes
Worm gearboxes, like any mechanical component, can experience various issues over time. Here are some common problems that may arise and possible troubleshooting steps:
- Overheating: Overheating can occur due to factors such as inadequate lubrication, excessive loads, or high operating temperatures. Check lubrication levels, ensure proper ventilation, and reduce loads if necessary.
- Noise and Vibration: Excessive noise and vibration may result from misalignment, worn gears, or improper meshing. Check for misalignment, inspect gear teeth for wear, and ensure proper gear meshing.
- Leakage: Oil leakage can be caused by damaged seals or gaskets. Inspect seals and gaskets, and replace them if necessary.
- Reduced Efficiency: Efficiency loss can occur due to friction, wear, or misalignment. Regularly monitor gearbox performance, ensure proper lubrication, and address any wear or misalignment issues.
- Backlash: Excessive backlash can affect precision and accuracy. Adjust gear meshing and reduce backlash to improve performance.
- Seizure or Binding: Seizure or binding can result from inadequate lubrication, debris, or misalignment. Clean the gearbox, ensure proper lubrication, and address misalignment issues.
- Worn Gears: Worn gear teeth can lead to poor performance. Regularly inspect gears for signs of wear, and replace worn gears as needed.
- Seal Wear: Seals can wear over time, leading to leakage and contamination. Inspect seals regularly and replace them if necessary.
If you encounter any of these problems, it’s important to address them promptly to prevent further damage and maintain the performance of your worm gearbox. Regular maintenance, proper lubrication, and addressing issues early can help extend the lifespan and reliability of the gearbox.
Worm Gearbox vs. Helical Gearbox: A Comparison
Worm gearboxes and helical gearboxes are two popular types of gear systems, each with its own set of advantages and disadvantages. Let’s compare them:
| Aspect | Worm Gearbox | Helical Gearbox |
| Efficiency | Lower efficiency due to sliding friction between the worm and worm wheel. | Higher efficiency due to rolling contact between helical gear teeth. |
| Torque Transmission | Excellent torque transmission and high reduction ratios achievable in a single stage. | Good torque transmission, but may require multiple stages for high reduction ratios. |
| Noise and Vibration | Generally higher noise and vibration levels due to sliding action. | Lower noise and vibration levels due to smoother rolling contact. |
| Backlash | Higher inherent backlash due to the design. | Lower backlash due to meshing of helical teeth. |
| Efficiency at Higher Speeds | Less suitable for high-speed applications due to efficiency loss. | More suitable for high-speed applications due to higher efficiency. |
| Overload Protection | Natural self-locking feature provides some overload protection. | May not have the same level of inherent overload protection. |
| Applications | Commonly used for applications requiring high reduction ratios, such as conveyor systems and heavy-duty machinery. | Widely used in various applications including automotive transmissions, industrial machinery, and more. |
Both worm and helical gearboxes have their place in engineering, and the choice between them depends on the specific requirements of the application. Worm gearboxes are preferred for applications with high reduction ratios, while helical gearboxes are chosen for their higher efficiency and smoother operation.
What is a Worm Gearbox and How Does It Work?
A worm gearbox, also known as a worm gear reducer, is a mechanical device used to transmit rotational motion and torque between non-parallel shafts. It consists of a worm screw and a worm wheel, both of which have helical teeth. The worm screw resembles a threaded cylinder, while the worm wheel is a gear with teeth that mesh with the worm screw.
The working principle of a worm gearbox involves the interaction between the worm screw and the worm wheel. When the worm screw is rotated, its helical teeth engage with the teeth of the worm wheel. As the worm screw rotates, it translates the rotational motion into a perpendicular motion, causing the worm wheel to rotate. This perpendicular motion allows the worm gearbox to achieve a high gear reduction ratio, making it suitable for applications that require significant speed reduction.
One of the key features of a worm gearbox is its ability to provide a high gear reduction ratio in a compact design. However, due to the sliding nature of the meshing teeth, worm gearboxes may exhibit higher friction and lower efficiency compared to other types of gearboxes. Therefore, they are often used in applications where efficiency is not the primary concern but where high torque and speed reduction are essential, such as conveyor systems, elevators, automotive steering systems, and certain industrial machinery.
