Mfy, mfyt and mfyx series of central drive mill reducer is a new low speed heavy duty reducer with independent intellectual property rights developed and designed according to the actual production situation in China. It is mainly used for mill with central drive.
Mfy series mill reducer adopts double split power, two-stage deceleration and concentric transmission. The reduction ratio is generally 20 ~ 80, and the maximum transmission power is 6000kW. Generally used for motor speed of 740r / min.
Mfyt series mill reducer adopts two-stage power split, three-stage deceleration and concentric transmission in structure, which can achieve large reduction ratio while driving large torque. The reduction ratio is generally 20 ~ 110, and the maximum transmission power is 8000 kW. Generally used for motor speed of 990r / min.
Mfyx series mill reducer adopts three-stage reduction in structure, the first stage adopts planetary gear transmission, the second and third stages adopt the structure of mfy series mill reducer, concentric transmission. The reduction ratio is generally 20 ~ 220, and the maximum transmission power is 8000 kW. Generally used for motor speed of 990, 1480r / min
The mill and the sliding bearing are designed to have a service life of 100000 hours.
It is equipped with a safe and reliable electric control and detection system, which can realize all bearing temperature inspection, vibration detection and computer control.
The reducer of central drive mill has the characteristics of small volume, light weight, large transmission capacity, long service life, convenient installation and maintenance, simple operation, stable transmission, low noise, high efficiency and low temperature rise. Due to the realization of the standardized and universal design of the series, it is convenient for users to maintain and supply spare parts.
