What is a Reduction Gearbox? How does a Speed Reducer Wo
A gear reducer is a major part of the vehicle that changes speed A speed reducer or reducing gearbox is used to reduce the input velocity of the engine while increasing the torque produced by the input The reduction gearbox has teeth on the pinions and wheels that mesh with each other to transfer power from the driver shaft to the driven shaft to reduce speedThese calculations ensure that the output torque of the reducer is safely over the load torque An underdesigned gear reducer will inevitably fail How Do I Find My Service Factor?
