Understand the basics of two-stage worm gearboxes comprehensively.
Ein two-stage worm gearbox combines two worm gear sets in series for high overall reductions in compact design. The model 1002M00413 for medical tables achieves a 200:1 reduction and 760 Nm torque, allowing for precise movements. Basics about worm gearboxes provide further details.
Each stage contains a worm that transfers rotational movement to a worm wheel. Through serial connection, the reduction effect is compounded:the speed decreases, torque increases. The axle-parallel shaft arrangement supports the compactness of these gearboxes..
They are suitable for applications with high reductions, precise positioning, and often self-locking in confined spaces, such as automation tasks with slow, powerful movements. A complete gear motor system, as configured by ATEK Drive Solutions for medical technology or conveyor technology, can be advantageous.Clearly evaluate the advantages and disadvantages of two-stage worm gearboxes.
A main advantage of two-stage worm gearboxes is the realization of high gear ratios (up to 1500:1) in compact housings. These gearboxes with two stages allow for enormous reductions in the smallest space, ideal for tight conditions and high torques, providing design benefits.
- Realization of extremely high gear ratios (e.g., up to 1500:1) in a compact design.
- Space-saving design through enormous reductions in the smallest space.
- Inherent self-locking in many models, serving as a safety feature that prevents reversal.
- Quiet and low-vibration operation, ideal for noise-sensitive applications.
- Lower mechanical efficiency compared to spur or bevel gearboxes.
- Potential for higher heat generation due to the efficiency, which may require cooling measures.
- Generation of axial forces that require robust bearing and careful design.
Self-locking is another plus point: Many models are self-locking by design and prevent reversal under load. This is an important safety aspect, e.g., in hoisting devices or medical adjustment drives, and can be more important than the efficiency of others. Bevel gearboxes..
Worm gearboxes, including two-stage ones, are known for quiet, low-vibration operation, ideal for noise-sensitive environments (labs, theaters, medical technology). For quiet applications, worm wheel gearboxes of this kind are suitable.
Disadvantages include the tendentially lower efficiency compared to spur or bevel gearboxes,especially at high single-stage reductions. This leads to higher heat generation (consider cooling) and axial forces that require adequate bearing and careful design.Optimize construction and design for maximum gearbox performance.
The choice of housing materials (e.g., aluminum die casting as with Nord Drivesystems’ SK 02040.1 or cast iron/steel for heavy-duty applications as with KLOSE Drive Technology) depends on the application. ATEK assists in the selection.
Correct material pairings (typically hardened steels for worms, bronze alloys for worm wheels) are crucial for lifespan, emergency running properties, and minimizing wear, even with special gearboxes.Precision machining is important.
Reliability, especially in a two-stage worm gearbox,requires thoughtful bearing concepts (ball/tapered roller bearings) and application-appropriate lubrication (oil bath, long-term grease, possibly lifetime lubrication).
The modular system of ATEK Drive Solutions allows numerous gearbox configurations with short delivery times by intelligently combining standard components for complex drive systems..Unlocking potential in your industry with two-stage worm gearboxes.
In machinery and plant engineering, two-stage worm gearboxes are relevant for high torques in the tightest spaces, e.g., in machine tools for precise feed or textile machines for uniform material guidance. Specific worm gearbox motors are often used; ATEK has experience in this area.

In robotics and automation, they are two-stage worm gearboxes beneficial for axes or handling systems with high holding forces and compactness. Custom adaptations (ATEK also for small series) are often crucial.Select optimal two-stage worm gearboxes based on key figures
The gear ratio (i) is central; two-stage worm gearboxes achieve high values (up to i=1500:1+). This is associated with the output torque (T2), e.g., 760 Nm in the medical table drive. Precise definition of these values is fundamental for selection.
- Accurately determine required translation and output torque.
- Define installation space and permissible weight.
- Analyze the type of load (constant, impact, reversing).
- Specify ambient conditions (temperature, protection class).
- Establish requirements for service life and maintenance intervals.
The efficiency (η), the ratio of output power (P2) to input power (P1), is generally lower in worm drives, and thus also in a two-stage worm gearbox,, tends to be lower (often 50-85% per stage) and must be considered in energy balance and heat generation. ATEK supports the design.
In addition to performance data, the available installation space and ambient conditions (temperature -15°C to +40°C, humidity, media) are crucial for selecting the suitable two-stage worm gearbox . This may require special seals, lubricants or materials like stainless steel worm gears .Leverage future trends in worm drives for competitive advantages
The development focuses on more efficient, compact worm gearboxes, including the two-stage worm gearbox,. One trend is research on tooth geometries, coatings and materials to improve efficiency. Miniaturization, even of such double worm gearboxes, opens fields in microrobotics or portable medical technology. ATEK follows these gearboxes.-innovations.
