Products

Please refer to the product brochure, which includes the technical data for worm and planetary gears, for details.

We would be happiest, however, if you asked us to work out the perfect drive for your special application.
Contact us for a non-binding and free-of-charge consultation.

Unfortunately, it is almost impossible to provide a general delivery time for new drives. Depending on their complexity and urgency, we can, however, usually produce prototypes within a few weeks‘ time.

We will, in any case, meet the promised delivery deadlines.

Worm and planetary gears are the heart and soul of almost all of our drives. If your application shows that a supplementary spur gear, bevel gear or belt stage would be advantageous: No problem.

Here we are absolutely open to your requirements. DC motors, EC motors, servo motors, three-phase and alternating current motors, as well as special motors can be installed. Contact us, we will be happy to meet your individual requirements.

Customer-tailored special drives

Sometimes yes, sometimes no. Our experience shows that it can be much more economical to customize the drive specifically to your needs. The advantage is a much greater one when it comes to peripherals, assembly, service, quality. If, however, a series gearbox is totally sufficient, we will tell you and take care of the rest.

The drives we produce are tailored to the customer and tuned especially to the individual case. Of course, we can also provide a standard drive which we procure from our partners.

  • You contact us
  • We ask you for the necessary technical details
  • We draft a rough design and technical concept and quote the price totally non-binding and free of charge (that takes about 1 to 2 weeks)
  • You give your OK
  • We develop the drive and present the design (that takes about 3 to 4 weeks)
  • You give your approval
  • We build some prototypes (delivery time depends on the complexity and supplier parts)
  • All fine and ready to go!
  • We start serial production
  • Operating mode (continuous operation S 1 or intermittent operation)
  • Required service life
  • Necessary torque and speed
  • Available space
  • Available voltage
  • Special environmental factors (temperature, humidity, vibrations …)
  • Increased axial and radial loads on the shaft
  • Self-locking feature
  • Supplementary equipment (brake, encoder …)

More than 1 but less than 10,000

Of course. We implement the basic European regulations on data protection 2016/679. All areas that require data processing are reliably protected and access follows a strict regiment

The conclusion of a mutual non-disclosure agreement is no problem at all.

Yes, it is. We have the know-how to design a drive solution made of stainless steel.

Basically yes. Contact us and we will build a drive with the protection class you require.

The requirements for an explosion-proof drive (ATEX) must be approved via type testing. Together with you and our external specialist, we develop the design that meets all requirements.

    Service

    The warranty follows the legal provisions and expires after 24 months.

    All Langguth drives comply with machine directive 2006/42 EC for incomplete machines.

    Adherence to further directives is, of course, possible. Please contact us for more information.

    Our products do not contain any substances in concentrations that would forbid their distribution and comply with all legal provisions, i.e. also RoHS and REACH.

    Yes, they can. On request, we can obtain the China Compulsory Certification (CCC) for drives that are delivered to China.
    Our certification partners are the TÜV Rheinland and the China Quality Certification Center (CQC).

    Gearboxes are considered incomplete machines according to EU Directive 2006/42/EC and therefore do not require any CE label. The CE label is necessary for the complete machine which is placed on the market. On request, we can provide an extended declaration of incorporation for an incomplete machine, which can subsequently be incorporated into the CE documentation.

    Yes, they can. It is possible to purchase motors with UL (mainly for the USA) and CSA (Canada) certification labels. The certification labels indicate that a product meets the applicable safety and performance standards of the relevant countries.

    All gear reducers are lubricated for life thanks to high-performance gear oil or gear grease; relubrication is not necessary.
    Trapezoidal-thread spindles are not maintenance-free in all applications. However, Langguth uses materials and lubricants that enable a very long service life.

    Gear technology

    One specialty of the worm drive is its self-locking feature, which can be a convenient and important safety criterion.

    Self-locking means that the input shaft allows no backward movement by the output shaft, i.e. the output shaft is blocked when the input shaft is standing still.

    Static self-locking means that gears that are standing still cannot even start under load (strong vibrations may, however, cause the gears to start moving slowly). Dynamic self-locking means that running gears brake safely and stay put when the motor is switched off.

    Self-locking depends on many factors.

    As rough indication we could say that a gearbox more or less self-locks at a reduction of i=30.

    A worm drive definitely self-locks when the pitch angle of the worm is less than the gear friction value converted into an angle value. The latter depends on the lubrication, the tooth shape and material, the run-in, the operating temperature and other values. Very often, a value of 5.5° for static self-locking and 3.5° for dynamic self-locking is realistic.

    Our Engineering Department would be glad to lay out your requirements.
