The TANDLER speed modulation gearbox is 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.
TANDLER guarantees High performance gearbox with quiet operation, High precision and concentricity, Minimal backlash, Spiral bevel gears from alloy carburited steel, hardened and lapped to give best surface contact. All gear sets may be processed with Palloid-, Cyclo-Palloid, HPG-S or with ground tooth flanks cutting, all sun gears and planetary gears are dressed to size to quality 4-5.
Using multi-start worm gears, the speed modulation ratio may be reduced to increase the speed of response.
TANDLER produces three series of speed modulation gearboxes:
PE Series | a simple gearbox with increasing or reducing ratio i=3;
PD Series | a dual-phase gearbox with ratio i=1
SP Series | a phase combined gearbox with angular transmission and inverter or clutch/knock-off device with various reducing and increasing ratios.
