Application of transmission mode of greenhouse top opening window slave system: 

1、 Direct window opening system: the rack of the system is hinged with the window, and the rack engages in the gear_ The gear is fixed on the drive shaft, which is supported by the bearing seat. When the reduction motor drives, the gear tooth strip is driven by the drive shaft to realize the opening and closing of the window. 

2、 Indirect window opening system: the indirect window opening system uses turbine reducer to replace the reduction motor in the direct window opening system. The power of the system comes from the reduction motor of about 30 revolutions per minute. The power is distributed to several turbine reducers through the torque distributor, so that one reduction motor drives several window systems, Indirect window opening system is rarely used in modern greenhouse.
