AISI 4140 Steel Planet Carrier Transmission Gear 240-280 HB Hardness Custom Helical Gear Reducer
Material: AISI 4140 (equivalent to 42CrMo Steel)
Hardness: 240-280 HB
Manufacturing: Complete machining process
The planetary gear train provides exceptional stability through even mass distribution and enhanced rotational stiffness. Drive power connects to the sun gear, which then drives the planetary gears assembled with the external gear ring for efficient operation.
Torque is transferred radially by the gears without lateral pressure on gear teeth, ensuring optimal performance and longevity.
A carrier connects the centers of the two gears and rotates the planet and sun gears mesh, ensuring pitch circles roll without slip. This precision engineering results in smooth, efficient power transmission.
