Since the Industrial Revolution, reducers have been an independent product with rapid development and a wide range of applications, including logistics, metallurgy, environmental protection, chemical and other fields. The deceleration device has been widely used in transmission and transmission devices, and has been widely applied in the mechanical industry and people's daily work.
In modern industry, many machines are driven by electric motors, and the transmission system is divided into prime movers, transmission mechanisms, and manufacturing mechanisms. In general, low-speed and large power units will use a reduction device, which can effectively reduce small rotational speeds and thus change the torque accordingly. Reducers can usually be divided into two types, namely single pole drive and multi segment drive. Regardless of the type of reducer, its internal components are composed of shafts, bearings, gears, couplings, and casings.
