Nguyên lý hoạt động
Three sequential planetary stages cascade torque multiplication. Stage 1 operates at the highest input speed with smallest module gears; stage 3 operates at the lowest speed with largest module gears and the highest torque. A one-piece forged planet carrier in the output stage eliminates the flex found in welded split-type carriers, ensuring even planet load distribution at peak torque. Oil-bath lubrication supports any mounting orientation without modification.
Lợi thế cốt lõi
