Precise power transmission, self-locking, and a robust design – the advantages at a glance.
What are the main advantages of a worm gear with hand crank for industrial applications?
The main advantages are natural self-locking, which securely holds loads without the need for an external brake, high ratios for significant power amplification with minimal manual effort and a compact design, that saves space. ATEK also offers custom modifications.
When is the self-locking of a manually operated worm gear particularly important?
Self-locking is crucial for safety applications, where a load must be precisely positioned and held, for example, when lifting and lowering platforms, adjusting safety devices, or during positioning processes that do not allow back rotation due to the load .
How do I choose the right housing material (steel vs. aluminum) for my worm gear?
Steel housings are suitable for heavy loads and harsh environments due to their robustness. Aluminum housings are lighter, offer good corrosion resistance and are ideal for mobile applications or when weight is a factor, such as in awning drives. ATEK is happy to advise you on the optimal material selection..
What does “maintenance-free” mean for ATEK worm gears with hand crank?
“Maintenance-free” at ATEK gears like the AZG series primarily refers to the lifetime lubrication and the closed, sealed design, which prevents the ingress of dirt. Regular visual inspections for external damage or unusual noises (e.g., every 500 operating hours) are still recommended to ensure a long service life.

Basic principle: Worm meets wheel
Understanding the power of manual control Manual operation is preferred in many industries despite automation, often due to the needed precision, direct interventions, and fail-safety. A, as offered by ATEK Drive Solutions GmbH for special machine modifications, embodies such a solution for these requirements.
Abgrenzung zu anderen Getriebearten
The basis is the special gearing of worm shaft and worm wheel, A rotating movement at a crank generates significant force.which allows high ratios in the smallest space, e.g., 60:1 in compact lifting devices.Distinction from other gear types
Although spur gears may be more efficient for pure power transmission,
worm gears provide natural self-locking. Other gear types often require additional components for this purpose, which is why worm gears are suitable for safety applications, like Pfaff Silberblau cranks. Functionality and advantages of worm gears This property is a central safety and comfort aspect,, z.B. beim Halten von Bühnenelementen bis 300 kg.
- e.g., when holding stage elements up to 300 kg. The core: Self-locking
- A core advantage that securely keeps loads in position without the need to hold the crank, especially at incline angles below 5 degrees. A feature of
- is their self-locking: A load remains positioned without holding the crank. This occurs at incline angles below 5 degrees. The self-locking makes operation safer and more comfortable, for instance when holding stage elements.
- Increased safety and comfort: Efficient power transmission:
- Self-locking: Allow for the movement of heavy loads or precise adjustments with minimal manual effort.
- Space-saving design: Ideal für Anwendungen mit begrenztem Einbauraum, wie in Verkaufsautomaten oder kompakten Hebevorrichtungen.
Translation: Low effort, high impact
High gear ratios: Minimal hand force generates great effect, ideal for applications such as moving heavy gates or fine adjustments., such as fine-tuning conveyor belt tensions. Such Compact design: Due to crossed axes and high ratios in small spaces, worm gears are often significantly smaller than other types of gears. Minimal hand force moves heavy gates via worm gear with high ratio (e.g., 50:1), reducing the required effort. custom gears for this purpose.
Kompaktheit im Design
Compactness in design Ideal for applications with limited installation space, such as in vending machines or compact lifting devices.This compactness, often 30% smaller than spur gears, is an advantage , especially with aFor applications with limited installation space and a need for high ratio, worm gears provide a solution. Crossed axes allow for space-saving constructions.worm gear with manual drive.
Material selection and designs
Housing: Steel or aluminum? A steel housing is not always more robust; aluminum alloys offer a good compromise. Steel (mining) withstands forces over 10,000 Nm.Aluminum is corrosion-resistant and lightweight, ideal for mobile applications such as awning drives (0.41 kg), which are often designed as manually operated worm gears. Stainless steel gears for special requirements
are another option.
Worm and wheel: A well-coordinated team Different materials are used for worm (often hardened steel, e.g., C45) and worm wheel (bronze/special brass). This pairing minimizes friction, wear and ensures emergency running properties.
This can mean over 1,000 operating hours of service life at full load.
Variety in form and function The high ratio is beneficial for manual precision adjustments can be designed as Getriebelösungen sind so zügig realisierbar.manually operated worm gears
Custom gear solutions
Although standard gears often fit, many situations require adjustments (hollow shafts, specific flanges). Worm gears with hand crank Modularity, like ATEK’s modular system (millions of configurations), allows for quick adjustments, even for a worm gear with hand crank. Die Selbsthemmung verhindert ungewolltes Verstellen durch Bearbeitungskräfte.
- Fertigungsindustrie: Ermöglichen präzise manuelle Feineinstellungen und Werkstückpositionierungen (z.B. 0,1 mm Genauigkeit bei Verstelltischen) mittels Kurbel-Schneckengetrieben, wobei die Selbsthemmung ungewolltes Verstellen verhindert.
- Bauwesen: Use in manually operated winches (e.g., HZW series up to 1200 kg) for lifting heavy components without a power connection, focusing on robustness and safe load holding.
- Stage and event technology: For silent and precise movement of heavy backdrops or lighting trusses, where quiet operation and exact control (up to 160 Nm) are crucial.
- Workshop and craft: To generate high pressing forces in small spindle presses or vises, appreciated for ease of use and durability.
- Safety applications: The natural self-locking is ideal for tensioning safety ropes or holding loads without additional brakes.
- General machine fittings: Where manual, powerful, and precise adjustments are needed, such as lifting workpieces up to 50 kg.
Power packs in construction
Manually operated winches with worm gears (HZW series, up to 1200 kg load capacity) lift heavy components without a power connection. In these manual worm gears robust construction and safe load holding are crucial, e.g., when tensioning safety ropes.
Invisible helpers in stage technology
Heavy backdrops/lighting trusses move silently and precisely with worm gears with hand crank (theatrical technology, torques up to 160 Nm). The quiet operation is an advantage.
Versatility in workshop and craft
For manual generation of high pressing forces, small spindle presses/vises use the power amplification of worm gears. Ease of use and low maintenance ensure durability, typical for a worm gear with manual operation. Example: Lifting workpieces up to 50 kg.Selection criteria, maintenance, and modern aspects
Selecting the right gear
When selecting, the gear ratio (5:1 fast, 60:1 torque), torque (up to 1800 Nm), and environmental conditions (temperature -20°C to +60°C, dust) are crucial, especially for a Worm gears with hand crank. Safety features like a load-dependent backstop are important for lifting applications.Lifting gears for specific lifting tasks require attention here.
Maintenance: Myth of ‘maintenance-free’?
‘Maintenance-free’ usually means lifetime lubricated and sealed gears (e.g., AZG series). It primarily refers to lubrication; regular inspection (every 500 operating hours) for damage/noise is recommended, even for a manually operated worm gear.
Modern developments in focus
Manual drives are evolving: sensor integration, new materials (high-performance plastics). Motor support for short-term operation extends application possibilities (rapid coarse adjustment, manual fine tuning). Digitalization facilitates selection through online configurators, also for the suitable Worm gears with hand crank.
Worm gears with hand crank are a reliable, precise solution for manual drive tasks. Self-locking, high ratios, and robust construction are their essential advantages.
