Helıcal Gear Reducers

What is the  Helical Gear reducer and where to use it  ?

The helical reducer isa major component of the gearbox that amplifies the torque and controls the speed. Typically, the torque increases while the speed reduces. To increase the torque, the output shaft of a gearbox rotates slower than the input shaft of an engine.  It is commonly used in automation control systems.
