NAF type planetary gear reducer has the following main features:

1, light weight, small size, the program conditions than involute cylindrical gear reducer weight more than 1/2, volume 1/2-1/3

2, the transmission efficiency is high: single stage planetary retarder n=0.98, two slow planetary reducer n=0.96, three planetary reducer n=0.94

3, the transmission power range of projects, from less than 1 kW to tens of thousands of kilowatts, and the greater the power advantages more prominent, the economic benefit is high

4, the assembly type varied, polygonal installation, wide applicability, in line with the given manufacturing conditions, balanced running, low noise.

5, uses the high quality low carbon alloy steel carburizing and quenching, external gear 6 industrial countries the level of similar products.

The NAF type planetary gear reducer is mainly used in metallurgy, mining, transportation, building materials, light industry, energy, transportation and other industries, high-speed shaft speed according to the specifications: 200-800 is not greater than 1500r/min, 900-1000 is less than 1000r/min.

The circumferential speed of the gear is not more than 15-20m/s,

Work environment temperature of -40~+45 ℃, below 0 ℃, heat should be started before the lubricating oil to 0 ℃. Two opposite like running.
