Enclosed slewing drives are the most popular model of slewing drives and can help power movement in machinery such as wind turbines, digger derricks, solar trackers, medical equipment, forestry, waste management and industrial positioners. The housing fully encapsulates all the drive components such as the double enveloping worm gearset, planetary gearing, and turntable bearing, such that they have total protection from the elements. The Enclosed Drive is also advantageous if you’re mounting inside so as not to see the parts in motion, or to avoid injuring workers working in close proximity.
Slewing drives are ideal for jobs that require both load-holding and rotational torque from the same gearbox. The fully-enclosed comes with patented hourglass worm technology, or cone drives and double enveloping worm gearsets where required, for maximum load-holding and efficiency. Each size is rigorously tested for reliable performance, with base model sizes producing 6kNm to 2200kNm of holding torque, 200Nm to 630kNm of output torque, 500Nm to 2710kNm of overturning moment load capacity, and gearbox reduction ratios of 30:1 up to 156,600:1.

Can you provide examples of machinery that use worm gears?
Worm gears are utilized in various machinery and mechanical systems where precise motion control, high gear reduction ratios, and self-locking capabilities are required. Here are some examples of machinery that commonly use worm gears:
- Elevators: Worm gears are commonly employed in elevator systems to control the vertical movement of the elevator car. The high gear reduction ratio provided by worm gears allows for smooth and controlled lifting and lowering of heavy loads.
- Conveyor systems: Worm gears are used in conveyor systems to drive the movement of belts or chains. The self-locking nature of worm gears helps prevent the conveyor from back-driving when the power is turned off, ensuring that the materials or products being transported stay in place.
- Automotive applications: Worm gears can be found in automotive steering systems. They are often used in the steering gearboxes to convert the rotational motion of the steering wheel into lateral movement of the vehicle’s wheels. Worm gears provide mechanical advantage and precise control for steering operations.
- Milling machines: Worm gears are utilized in milling machines to control the movement of the worktable or the spindle. They offer high torque transmission and accurate positioning, facilitating precise cutting and shaping of materials during milling operations.
- Lifts and hoists: Worm gears are commonly employed in lifting and hoisting equipment, such as cranes and winches. Their high gear reduction ratio allows for the lifting of heavy loads with minimal effort, while the self-locking property prevents the load from descending unintentionally.
- Rotary actuators: Worm gears are used in rotary actuators to convert linear motion into rotary motion. They are employed in various applications, including valve actuators, robotic arms, and indexing mechanisms, where controlled and precise rotational movement is required.
- Packaging machinery: Worm gears find application in packaging machinery, such as filling machines and capping machines. They assist in controlling the movement of conveyor belts, rotating discs, or cam mechanisms, enabling accurate and synchronized packaging operations.
- Printing presses: Worm gears are utilized in printing presses to control the paper feed and the movement of the printing plates. They provide precise and consistent motion, ensuring accurate registration and alignment of the printed images.
These are just a few examples, and worm gears can be found in many other applications, including machine tools, textile machinery, food processing equipment, and more. The unique characteristics of worm gears make them suitable for various industries where motion control, high torque transmission, and self-locking capabilities are essential.
How do you retrofit an existing mechanical system with a worm gear?
When retrofitting an existing mechanical system with a worm gear, several considerations need to be taken into account. Here’s a detailed explanation of the retrofitting process:
- Evaluate the existing system: Before proceeding with the retrofit, thoroughly assess the existing mechanical system. Understand its design, function, and limitations. Identify the specific reasons for considering a worm gear retrofit, such as the need for increased torque, improved efficiency, or enhanced precision.
- Analyze compatibility: Evaluate the compatibility of a worm gear with the existing system. Consider factors such as available space, structural integrity, alignment requirements, and the load-bearing capacity of the system. Ensure that the addition of a worm gear will not compromise the overall performance or safety of the system.
- Select the appropriate worm gear: Based on the requirements and constraints of the retrofit, choose a suitable worm gear. Consider factors such as gear ratio, torque capacity, efficiency, backlash, and mounting options. Select a worm gear that matches the specific needs of the retrofit and is compatible with the existing system.
- Modify or adapt the system: Depending on the compatibility analysis, it may be necessary to modify or adapt certain components of the existing system to accommodate the worm gear. This can involve making adjustments to shafts, bearings, housings, or other mechanical elements. Ensure that any modifications or adaptations are carried out with precision and adhere to industry standards.
- Install the worm gear: Install the selected worm gear into the modified or adapted system. Follow the manufacturer’s instructions and guidelines for proper installation. Pay attention to torque specifications, lubrication requirements, and any specific assembly procedures. Ensure that the worm gear is securely mounted and aligned to minimize misalignment and maximize performance.
- Test and optimize: After the installation, thoroughly test the retrofitted system to ensure its functionality and performance. Conduct tests to verify torque transmission, efficiency, backlash, noise levels, and any other relevant parameters. Monitor the system during operation and make any necessary adjustments or optimizations to fine-tune its performance.
- Document and maintain: Document the retrofitting process, including any modifications, adjustments, or optimizations made to the existing system. Keep records of installation procedures, test results, and maintenance activities. Regularly inspect and maintain the retrofitted system to ensure its continued performance and reliability.
It’s important to note that retrofitting an existing mechanical system with a worm gear requires expertise in mechanical engineering and an understanding of the specific system requirements. If you lack the necessary knowledge or experience, it is advisable to consult with professionals or engineers specializing in power transmission systems to ensure a successful retrofit.
Understanding Worm Gears and Their Operation
A worm gear is a type of mechanical gear that consists of a threaded screw-like component (called the worm) and a toothed wheel (called the worm gear). It is used to transmit motion between non-intersecting and perpendicular shafts. Here’s how it works:
The worm, typically in the form of a cylindrical rod with a helical thread, meshes with the teeth of the worm gear. When the worm is rotated, its threads engage with the teeth of the worm gear, causing the gear to rotate. The direction of rotation of the worm gear is perpendicular to the axis of the worm.
One significant feature of worm gears is their ability to provide high gear reduction ratios. The number of teeth on the worm gear relative to the number of threads on the worm determines the reduction ratio. This makes worm gears suitable for applications where high torque and low-speed rotation are required.
Worm gears are commonly used in various mechanical systems, such as conveyor systems, lifts, automotive steering mechanisms, and more. Their unique design also provides a self-locking feature: when the system is not actively rotating the worm, the gear cannot easily backdrive the worm due to the angle of the threads, providing mechanical advantage and preventing reverse motion.
