Four speed helical gearbox BFY87
High strength and high precision
Output method: parallel axis output/forward and reverse
Transmission mode: rack and fork shifting, four-speed transmission, with neutral (clutch function)
Rack and fork slip shifting, changing the transmission route in the transmission chain, thereby changing the transmission ratio or achieving forward and reverse rotation.
Assembly type：
Looking forward from the rear of the input shaft of the gearbox, the speed control handle is represented by R on the left (right-hand model) and L on the right (left-hand model).
The parallel axis four speed transmission gearbox adopts a modular design, with a small volume and large center distance transmission structure, which has a 10% higher torque transmission capacity and load impact resistance. It is suitable for some transmission systems on production lines such as electrical machinery and cable equipment.
