NSR Series Belt Reducer

NSR Series Belt Reducer

NSR series cooling tower belt reducer adopts spiral bevel gear transmission, through flange cooperation, the motor center and the gear box gear center are exactly the same. The motor directly drives the reducer without transmission shaft to transmit the torque. Power ranges from 4 kW to 110 kW.

Newin NSR series belt reducer is used for round cooling tower, the belt has good elasticity. The Belt is the middle part, it can be in a certain range according to the need to choose the length, to adapt well the center distance requirements of the larger working conditions. Belt reducer has the characteristics of simple structure, stable operation, small vibration, low noise, long service life, etc.


■ High operating reliability, no need to adjust the belt tension, completely solve the maintenance work caused by belt slippage
■ High transmission efficiency, completely solve the power loss caused by belt slippage, and the air output of the fan is more guaranteed
■ Convenient installation: the gear box is an integrated structure, which makes installation easier and more convenient, reduces installation requirements and reduces installation labor costs.
