Specifications, type, transmission type, transmission ratio and output torque.
Two, the main features
1 light weight, small size, in the phase object conditions, than the hardened tooth surface involute cylindrical gear reducer weight loss of more than 1/2, the body position reduced by 1/2-1/3
2 high transmission efficiency: single planetary retarder n=0.98
Two slow planetary reducer n=0.96
Three stage planetary reducer n=0.94
3, the transmission power range is large, from less than 1 kilowatts to 10000 kilowatts, and the greater the power, the more prominent, the higher the economic benefits
The assembly type is diverse, can be multi-faceted installation, wide applicability, in accordance with the given manufacturing conditions, running balance, small noise.
5, the use of high quality low carbon steel carburizing quenching, the external gear for the 6 fine
Into the industrial countries, similar products level.
Three, applicable conditions
NGW planetary gear reducer standard, including NAD.NAZD.NB
A series of NBZF.NCZF Shiershi and derived NASO.NASF.Nl
Design
Mainly used in metallurgy, mining, transportation, building materials, light industry, energy, transportation and other industries.
High speed uranium RPM according to specifications:
200-800 is not greater than 1500r/min
900-1000 is not greater than 1000r/min
The circumferential speed of the gear is not greater than 15-20m/s, the working environment temperature is -40~+45 degrees Celsius, lower than 0 degrees Celsius, before starting, the lubricant should be heated to more than 0 degrees celsius. Reversible two image operation.
Four code and tag method
