  • Gear ratio of 1:1
  • Maximum torque 2500 Nm
Tandler PD2 double-planetary speed modulation gearbox

Tandler PD2 double planetary speed modulation gearbox with an overall ratio of 1:1. The combination of a planetary gear and worm gear is used for narrow range speed control and precise shaft phasing.

Features Tandler PD2 double-planetary speed modulation gearbox

  • Coaxial version with 2x PE2 in-inline planetary gear.
  • 7 bouwgrootten with overall gear ratio of 1:1.
    - Ratio of shaft d1
      i = 1:1
    - Ratio of shaft d3
      PD2: i = n3:n1 = n3:n2 = 135:1
      PDS: i = n3:n1 = n3:n2 = 45:1
  • Maximum torque up to 2500 Nm (PD2) and 830 Nm (PDS).
  • Maximum power up to 70 kW.
  • Max. speed at shaft d1 1000 min-1 (PD2) and 3000 min-1 (PDS).
  • Max. speed at shaft d3 3000 min-1.
  • Using multi-start worm gears, the speed modulation ratio may be reduced.
  • Coaxial input and output.

Tandler PD2 double-planetary speed modulation gearbox
  • High precision and long life span

    Tandler produces the speed modulation gearbox with highest precision and maximum service life for mechanical engineering. Highest quality speed modulation gearbox thanks to the highest gear tooth quality, available up to class 1. All products are subject to inspection during all phases of the product process and are carefully checked again before delivery. Read about it in Rico's blog.

  • Support with selection speed modulation gearbox

    We will calculate and select the best speed modulation gearbox for your application according to your specifications and requirements.

  • Client-specific requirements

    Tandler offers an almost unlimited variety of speed modulation gearbox combinations and variatorions, gearboxes with customised features and special speed modulation gearboxes to meet your requirements.

    From one up to three additional shafts, you will find the perfect solution:

    • Numerous special options available, such as reinforced bearings
    • Versions for special requirements such as use in the food industry
    • Various corrosion resistant finishes: aluminium, stainless steel, painting or Tenifer 30 NO treatment
  • Speed adjustable within narrow range

    The Tandler speed modulation gearbox stands out because the rotational speed is adjustable within a very narrow range.

  • Precise shaft phasing

    Precise shaft phasing by reducing or increasing the speed with using multi-start worm gears.

  • Quick response, short lines
  • Renowned manufacturers
  • Profound product knowledge
  • High reliability

We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.


In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
