The Gear Industry Status And Development Trend

Internationally, the gear is along the direction of miniaturization, high speed, standardization development. development of application of special gear, planetary gear set, low vibration, low noise gear is gear design and manufacture some of the characteristics of the device. for gear small purpose, can improve the bearing capacity of existing gear thrust. Universal adopts hard tooth surface technology, improve hardness to reduce device size; can also be represented by the circular arc gear of special gear. British and French development cooperation after the main drive system of ship-borne helicopters using circular arc gear and reducer height is greatly reduced. With the trend of ship power replaced by medium-speed diesel engine, power planetary gear set on large ships are indeed effective; now, metallurgy, mining, cement mill large gear, planetary gear as small size, coaxial is good, high efficiency and application of more and more.
