Product Description

The straight worm structure is adopted, and the gear part of slewing bearing is quenched by isothermal and high frequency, the tooth part has high hardness and good wear resistance.The contact area between the turbine and the worm is large, the operation is stable, the transmission torque is large, the transmission efficiency is high.

Description
There are no special limitations of mounting angles and positions of this series of products.  It can be mounted horizontally, vertically and inclined.  Enclosed slewing drives are assembled of enclosed housing, slewing bearing, worm shaft and other parts.  Users can choose electric motors or hydraulic motors as the driving power.  It can slew 360 degrees clock-wise or otherwise.  The slewing drive is compact and it is also easy to mount and maintain in comparison with other types of driving devises.
 
Features
It adopts enclosed design and the protection level can reach IP65.  It can effectively prevent dust, rain and other hostile environments.  It suits field usage such as desert, alpine and other hostile environments.
1.Products are easy to mount and maintain.
2.The design and mounting dimensions are international or domestic universal dimensions.  It is easy for the users’ replacements in the future.
 
Applications
1.This series of products are widely applied in the turning parts in construction machinery and solar power industries.
2.The azimuth and elevation drivers of solar tracking systems
3.The rotations of turntables or cranes in various types of construction machinery
4.The rotating parts of industrial equipments such as welding positioners

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-locking.

Can a Worm Gearbox Be Used in Heavy-Duty Machinery?

Yes, a worm gearbox can be used in heavy-duty machinery and is often chosen for such applications due to its inherent characteristics and advantages:

  • High Torque Transmission: Worm gearboxes are known for their ability to transmit high torque loads, making them suitable for heavy-duty machinery that requires significant power transmission.
  • Load Distribution: The design of worm gears provides robust load distribution and excellent contact between the worm and worm wheel teeth. This enhances their load-carrying capacity, making them capable of handling heavy loads without premature wear or failure.
  • Compact Design: Worm gearboxes are compact and offer high reduction ratios in a single stage. This allows for the reduction of high input speeds to lower output speeds, often required in heavy-duty machinery.
  • Overload Protection: Worm gears have a natural self-locking feature, which means the gear cannot be easily back-driven by external forces. This feature provides inherent overload protection, preventing damage to the gearbox and machinery in cases of sudden load spikes.
  • Smooth Operation: Worm gearboxes offer smooth and steady operation, which is crucial for heavy-duty machinery where precision and controlled movement are essential.

However, when considering the use of a worm gearbox in heavy-duty applications, it’s important to ensure proper engineering and sizing. The design should account for factors such as load, speed, duty cycle, lubrication, and temperature to ensure optimal performance and longevity.

Overall, worm gearboxes are well-suited for heavy-duty machinery across various industries, including mining, construction, manufacturing, and more.

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.

Preventing Backlash in a Worm Gearbox

Backlash in a worm gearbox can lead to reduced accuracy, positioning errors, and decreased overall efficiency. Here are steps to prevent or minimize backlash:

  • High-Quality Components: Use high-quality worm gears and worm wheels with tight manufacturing tolerances. Precision components will help reduce backlash.
  • Proper Meshing: Ensure the worm gear and worm wheel are properly aligned and meshed. Improper meshing can lead to increased backlash.
  • Preload: Applying a small amount of preload to the worm gear can help reduce backlash. However, excessive preload can increase friction and wear.
  • Anti-Backlash Mechanisms: Consider using anti-backlash mechanisms, such as spring-loaded systems or adjustable shims, to compensate for any inherent backlash.
  • Lubrication: Proper lubrication can reduce friction and play a role in minimizing backlash. Use a lubricant that provides good film strength and reduces wear.
  • Maintenance: Regularly inspect and maintain the gearbox to identify and address any changes in backlash over time.

It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.
