SF77 ... Helical gear worm gear reducer (without motor)

description

S77 / SA77 / SF77 / SAF77 / SAZ77 / SS77 / SAS77 / SFS77 / SAFS77 / Helical gear worm gear reducer (no motor) series worm gear reducer has the usual characteristics, using the form of helical gear worm gear to make the structure more reasonable , Not only makes the transmission efficiency and load capacity higher than the single-stage worm gear transmission, but also reduces the space occupation in the structural layout, and at the same time can obtain a larger transmission ratio under similar volume conditions. It is more conducive to equipment configuration. The machine can be used in combination with various speed reductions and gearboxes to meet different usage requirements.
