What are the advantages of planetary reducer?

planetary high speed gearbox is a wide range of industrial products, its performance can be comparable with other military grade reducer products, but it has the price of industrial products, mainly for the tower crane rotation mechanism, but also as a supporting component for Lifting, mining, transportation, construction and other industries.
small bevel gearboxes has the advantages of small size, relatively compact structure, small return gap, high transmission efficiency, wide range of deceleration, high precision, long life, rated output torque can be done very large. So it is widely used in servo, step, DC and other transmission systems. Its role is to ensure that the premise of precision transmission, mainly used to reduce the speed increase torque and reduce the load / motor moment of inertia ratio.
