Helical Gear Reducer
F сериялы параллель біліктің спиральды тісті редукторы
The F series helical gearbox is a parallel shaft helical gearbox; its input shaft and output shaft are parallel. F series parallel shaft helical gearbox has the advantages of a compact structure, ample transmission torque, stable operation, low noise, and long service life. The essential 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 primary two stages, 94% for the three stages, and 85% for the F Series and R Series combination.
As one of the helical gear reducer manufacturers, suppliers, and exporters of mechanical products, We offer helical gear reducer and many other products. Please get in touch with us for details.
