Key Specifications of the Reducer

The 303L Series planetary gearbox boasts a torque range of 1000-450,000 Nm and can transmit mechanical power up to 540kw. It has gear ratios of 3.4-9,000 and comes in in-line gear unit versions. The output configurations include foot and flange mounting, and the input configurations can accommodate flanged axial piston hydraulic motors, hydraulic orbit motors, IEC and Nema motor adaptors, and a solid input shaft.

Performance Characteristics of the Reducer

The main structures of the reducer include the sun gear, planetary gear, inner gear ring, and planetary carrier. To evenly distribute the load of the three planetary gears, the sun gear or planetary carrier floats, or both the sun gear and planetary carrier float at the same time. The gears in the reducer are straight involute cylindrical gears.
