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

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.
How to Calculate the Input and Output Speeds of a Worm Gearbox?
Calculating the input and output speeds of a worm gearbox involves understanding the gear ratio and the principles of gear reduction. Here’s how you can calculate these speeds:
- Input Speed: The input speed (N1) is the speed of the driving gear, which is the worm gear in this case. It is usually provided by the manufacturer or can be measured directly.
- Output Speed: The output speed (N2) is the speed of the driven gear, which is the worm wheel. To calculate the output speed, use the formula:
N2 = N1 / (Z1 * i)
Where:
N2 = Output speed (rpm)
N1 = Input speed (rpm)
Z1 = Number of teeth on the worm gear
i = Gear ratio (ratio of the number of teeth on the worm gear to the number of threads on the worm)
It’s important to note that worm gearboxes are designed for gear reduction, which means that the output speed is lower than the input speed. Additionally, the efficiency of the gearbox, friction, and other factors can affect the actual output speed. Calculating the input and output speeds is crucial for understanding the performance and capabilities of the worm gearbox in a specific application.
What Industries Commonly Use Worm Reducers?
Worm reducers are versatile mechanical components that find applications in various industries due to their unique advantages and capabilities. Some of the industries that commonly use worm reducers include:
- Material Handling: Worm reducers are widely used in material handling equipment such as conveyors, bucket elevators, and cranes to control movement and manage heavy loads.
- Automotive: They are utilized in automotive manufacturing processes, assembly lines, and vehicle positioning systems.
- Food and Beverage: Worm reducers are used in food processing and packaging machinery where hygiene and cleanliness are crucial.
- Agriculture: Agricultural equipment like irrigation systems and tractors use worm reducers for controlling rotational motion.
- Mining and Construction: Heavy-duty applications in mining equipment, excavators, and construction machinery benefit from the torque multiplication provided by worm reducers.
- Energy: Wind turbines and solar tracking systems use worm reducers to convert low-speed, high-torque motion into rotational energy.
- Textile: Textile machinery employs worm reducers for controlling speed and tension in weaving and spinning operations.
- Packaging: Packaging equipment relies on worm reducers for precise movement and positioning of packaging materials.
- Medical: Medical devices and equipment often utilize worm reducers for their accuracy and controlled motion.
- Printing: Printing machines use worm reducers to regulate paper feed and ensure consistent printing quality.
Worm reducers’ ability to provide high torque output, compact design, and self-locking characteristics makes them suitable for applications requiring reliable and controlled motion across various industries.
