2:1 ratio gearbox is used to transmit rotary motion, mechanical power and torque from input shaft to output shaft by pairs 90 degree assembly spiral bevel gears. Transmission efficiency up to 98%. Transmission gear ratio 1:1, 1.5:1, 2:1, 3:1, 4:1 and 5:1. 8 types shaft arrangements and direction of shaft rotating, 11 types mounting positions. Solid shaft and hollow shaft are available. 2 way, 3 way and 4 way drive shaft configurations. Allowable revolustions from 50 Rpm to 1500 Rpm, power rating from 0.04Kw to 157Kw, work torque from 11.59N.m to 1841.24N.m. Compared to worm gear reducer, 2:1 ratio gearbox is of low transmission gear ratio, low backlash arc, quiet running, high transmission efficiency and high torque.

2:1 ratio gearbox is equivalent to America THOMSON KRG bevel gearbox, Germany PFAFF KA bevel gearbox, INKOMA KL bevel gearbox, ZZ-ANTRIEBE K bevel gearbox, GROB V bevel gearbox.
