Note

S77/SA77/SF77/SAF77/SAZ77/SS77/SAS77/SFS77/SAFS77/Helical gear worm gear reducer (without motor) series worm gear reducer has the usual characteristics, the machine also uses helical gear-worm gear form, so that The structure is more rationalized, which not only changes the transmission efficiency and carrying capacity higher than that of the single-stage worm gear transmission, but also reduces the space footprint in the structural layout, and at the same time, can obtain a larger transmission ratio under similar volume conditions. It is more conducive to the configuration of the equipment. The machine can be combined with various reduction and transmission to meet different usage requirements.
