ОПИСАНИЕ

ФЛК P series heavy duty planetary gear reducer can be combined with K, R, S and other series according to requirements with modular design. The epicyclic gearboxes size is highly flexible and offers a wide range of options. Compact structure and high torque, suitable for heavy duty conditions. The epicyclic gearboxes have the features of high transmission ratio, high efficiency, smooth rotation, low noise and good applicability. Multiple planetary wheels transmit loads at the same time, so that the power is shunted and the synthesis and decomposition of motion is realized.
