K77 / KA77 / KF77 / KAF77 / helical gear worm gear reducer (without motor) series worm gear reducer has the usual characteristics, the machine also adopts the form of helical gear worm gear, which makes the structure more reasonable, not only changes the transmission efficiency but also has a higher load capacity than a single stage worm gear drive, but it 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 device configuration.The machine can be used in combination with various speed reduction and gearboxes to meet different usage requirements.
