TANDLER speed modulation gearboxes are the perfect solution for any application requiring shaft phasing, precise registration or narrow range speed control. Forwards or backwards speed modulation is generated when the worm shaft d3 which engages the outer sun wheel, is rotated.
| Series SP2 | Planetary spiral bevel gearbox, input and output at right angles |
| Series PE2 | Single stage planetary gearbox, coaxial |
| Series PD2 | Double stage planetary speed modulation gearbox, coaxial |
| Series KD | In-line bevel differential speed modulation gearbox, coaxial |
Using multi-start worm gears, the speed modulation ratio may be reduced to increase the speed of response.
