F series helical gearbox is parallel shaft helical gearbox, its input shaft and output shaft are parallel. F series parallel shaft helical gearbox has the advantages of compact structure, large transmission torque, stable operation, low noise and long service life. The basic two-stage input and output rotate in the same direction, while the third-stage rotates in the opposite direction. It can be used in combination with R series helical gearbox. The average efficiency is 96% for the basic two stage, 94% for three stage, and 85% for the F Series and R Series combination.
4 main types of F series helical gearbox:
foot-mounted solid shaft output F series
hollow shaft output FA series
flange-mounted hollow shaft output FAF series
flange-mounted solid shaft output FF series
