gear reducer with center drive configuration
1.MFY, MFYT and MFYX series gear reducers with center drive configuration are new type of gearboxes with feature of low speed, heavy duty, which possess independence intellectual property rights and which are designed and developed on basic of rich experience of foreign production actuality and advanced technology from abroad. They are mainly used for the central driving mill.
The configuration of MFY series reducers are double distributaries, two-stage and center drive. The reduction ratio is 20-80. The max transmission power is 6000KW. Normally, the motor whose rotation speed is 740r/min is adopted.
The configuration of MFYT series reducers are double distributaries, three-stage and center drive. The bigger reduction ratio can be gained during transmitting large torque. The reduction ratio is 20-110. The max transmission power is 8000KW. Normally, the motor whose rotation speed is 990r/min is adopted.
The configuration of MFYX series reducers are center drive and three-stage, in which the construction of the first stage is planetary gear transmission and in which the second and third stages are the same as that of MFY series reducers. The reduction ratio is 20-220. The max transmission power is 8000KW. Normally, the motor whose rotation speed is 1480r/min is adopted.
The center drive reducers are all case-hardened tooth flanks; the rolling bearing life is more than 100 thousand hours; the sliding bearing and gear are infinite life design.
The arrangement of the safe and reliable electric control and measuring system makes the temperature scanning; the vibration test and the computer control of all bearing are being realized.
The advantages of the center drive reducers are compactness, light weight, high capacity of transmission, long service life, smooth operation, low noise, easy operation, less maintenance easy spare parts available due to engineering concept of standardization and generalization.
