The model number of NMRV turbine gearbox directly corresponds to the center distance of the machine base (unit: mm). The larger the value, the higher the box size, load-bearing capacity, and upper limit of the adapted motor power
In addition to the basic single-stage model, dual stage/composite models can also be expanded through
modular combinations to achieve greater reduction ratios:
Double stage turbine reducer series type: such as NMRV40/75, NMRV63/130, the total speed ratio can
be extended to over 1000Composite integrated type: such as NMRV+WB cycloidal pinwheel combination, NMRV+MB continuously
variable transmission combination, suitable for special speed regulation requirements
