Planetary spiral bevel gearbox

  • Planetary spiral bevel gearbox
  • 8 standard ratios
  • Max torque 2500 Nm
Tandler SP2 planetary spiral bevel speed modulation gearbox

The Tandler SP2 planetary spiral bevel gearbox is a combination of spiral bevel, planetary and worm gear technology allowing changes in the angular position of the output shaft relative to and at right angles to the input shaft. The SP2 speed modulation gearbox also provides the capability to vary the output speed within a narrow range.

Tandler SP2 planetary spiral bevel 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.
