Descriptions of PLF Series Economic Planetary Gearbox

The 3F famed PLF series standard planetary gearbox is a kind of precision inline gearbox or coaxial reducer with a square flange which ensures the stablity of the speed reducer. The planetary carrier of 3F famed speed reducer adopts double bracing structure design, the front and rear bearings are distributed in the box body over a long span to form a stable integral structure to ensure higher stiffness and accuracy. The main transmission structure of planetary reducer consists of a sun gear, three planet gears and a ring gear and all remains in constant meshing. The operating principles ogf the speed reducer is reducing the speed of the motor and incresing the transmission torque.

Features of PLF Series Economic Planetary Gearbox

  • High rigity & high torque

The 3F famed PLF series standard planetary gearbox is equipped with a compact structure with the using of high quality alloy steel shell and uncaged needle roller bearings which gurantee the high rigity and high torque of the VRL planetary speed reducer.

  • High positioning accuracy

The gear of PLF economic planetary gerabox is manufacturered with the imported helical gear by high processing technology from Germany. Besides, the backalsh is lower to 3 arcmin.

  • Good sealing and no leakage

The PLF gearbox adopts full synthetic lubricating oil with high viscosity which made the speed reducer runs smoothly.

  • Excellent wear resistance

The gear material is made of high quality alloy steel and carbonitriding to obtain the best wear resistance and impact toughness.


The PLF economic planetary gearbox is widely used in CNC machine, cutting and welding equipment, textile printing and dyeing machinery, packaging machinery, food machinery, medical machinery, data communication system, robot, mechanical arm, composite material equipment, precision testing instrument, test machine, plastic machinery, glass machinery, coal mine machinery, lifting machinery, metallurgical machinery, engineering machinery and other industries.
