- Scope
- This standard specifies the type, size, basic parameters and technical requirements of NGW type planetary gear reducers of NAD, NAZD, NBD, NBZD, NCD, NCZD, NAF, NBF, NCF, NAZF, NBZF and NCZF series. This standard is mainly applicable to metallurgical mining, transportation, building materials, light industry, energy, transportation and other industries. The high-speed shaft speed of the reducer is 1500~600r/min according to its specifications. The peripheral speed of the reducer gear transmission is not greater than 15m/s for spur gears and not greater than 20m/s for helical gears. The working environment temperature of the reducer is -40~+45℃. When it is lower than 0℃, the lubricating oil should be preheated to above 10℃ before starting. The reducer can operate in both forward and reverse directions.
