Metal gears from Framo Morat

High-precision gears for the watchmaking industry were our company’s first products, and even today our metal gears embody the virtues of the Black Forest – reliability, attention to detail, a pioneering spirit, and the pursuit of perfection.

Our metal product portfolio now includes spur gears, pinion shafts, rotor shafts, and ring gears with internal and external teeth, as well as sprockets, gear segments, and special profiles. We develop and manufacture all of these components individually according to your requirements and design priorities – making use of the distinct properties of steel, aluminum, and numerous non-ferrous metals.

We carry out all quality-critical process steps in-house. These include turning, milling, and gear cutting, as well as hardening in our own heat treatment furnaces and final hard machining. Thanks to these extensive in-house manufacturing capabilities, we can perform even complex machining tasks precisely according to your specifications and the highest quality standards.

Humanoid robots are increasingly performing tasks in logistics, assembly, and industrial assistance. This requires high-precision transmission solutions that enable delicate, controlled movements, even in extremely compact spaces. Our planetary stages are used in larger axes such as hips and knees, to provide maximum mobility, precise control, and reliable torque transmission. Through close co-engineering collaboration with our customers, we develop custom components that combine high torque density with low weight.

Pump technology

Gear-type high-pressure pumps generate a steady, pulsation-free flow of liquid at high pressures. This is achieved through the rotation of intermeshing pump gears that suck in, enclose, transport, and finally displace the fluid at the outlet. Framo Morat supplies custom-tailored pump gears that stand out due to their tight manufacturing tolerances, high gear quality grades, and excellent surface finishes. From the initial design phase, we consider industry-specific material, thereby ensuring the efficient and long-lasting operation of pump systems.

Environmental technology

Rotor blades of wind turbines adapt continuously to changing wind conditions. To enable this precise adjustment, Framo Morat manufactures large-scale planetary gear components, such as ring gears, that reliably absorb and transmit enormous forces. These components play a crucial role in maximizing energy yield and ensuring system stability throughout its service life.

Construction machinery

In the engines and transmissions of construction machinery, gearing components, such as specially designed pump gears, must be built to withstand constant extreme forces. These components are exposed to fluctuating torques, as well as high pressure and temperature peaks. To ensure a long service life, operational safety, and reliable function under these demanding conditions, Framo Morat relies on exceptionally robust designs, wear-resistant materials, and high-precision manufacturing.

Agricultural machinery

Transmission components such as specially developed worm gear sets or spur gears enable continuously variable or partially autonomous driving in modern tractors. Framo Morat components meet the highest demands in this application: They can withstand the extreme loads of tough field operations and provide the reliability, durability, and longevity that farmers need – day after day and throughout the entire service life of the machine.

Current reference project

Screw wheel gearbox for cutting machines

In professional cutting machines, such as those used in the catering industry and in retail sausage and cheese counters, drive components must be particularly precise, durable, and reliable. This is exactly where Framo Morat's worm gear comes into play: it was developed to transmit the rotating movement of the machine efficiently and evenly.

The robust gear solution is based on worm gear sets with a center distance of 28 mm and a transmission ratio of i = 8. It combines a hardened precision worm with a worm wheel made of hard fabric. The excellent sliding properties of the hard fabric reduce friction and enable smooth, low-wear operation – even in demanding continuous use.

The advantages at a glance:

  • Long service life: Low-wear pairing of hardened worm and hard fabric wheel ensures reliable operation for many years.
  • Low maintenance: The self-lubricating properties of the hard fabric minimize the need for lubrication and reduce downtime.
  • Reliable performance: Stable power transmission even at high torques and in continuous operation.
