1) Description of Gearbox Speed Reducers
A speed reducer is a gear train between the motor and the machinery that is used to slow down the
transmission of power. Speed reducers, also known as gear reducers, are mechanical devices that
serve two roles. The primary function of a gear reducer is to duplicate the amount of torque produced
by an information power source in order to increase the amount of work that can be done.
2) Functions Gearbox Speed Reducers
Speed reducers have two primary functions. They double the torque produced by the power source (the input)
first. Second, as the name says, speed reducers reduce the input speed so that the output is the correct speed.
A speed reducer's output gear has more teeth than the input gear. As a result, while the output gear may
revolve more slowly than the input gear, the torque is enhanced.
