Vertex Precision What is Planetary Gearbox? A planetary gearbox is a mechanical device consisting of sun gear, the planet gears, the planet gears’ carrier, and the ring gear. Sun gear is located at the center that transmits torque to planet gears orbiting around the sun gear. Planet and sun gears are located inside the ring gear. Multi-staged planetary gearbox is available by connecting the individual stage in sequence. With the gear unit combination the individual stage is sized to the torque requirement. Sun Gear Planet Gears Planet Gears’ Carrier (output shaft) Internal Ring Function of...

Vertex Precision How to select a proper Planetary Gearbox? How to select a proper Planetary Gearbox for meeting specific application requirement, following factors need to be considered: Gear Ratio Speed (rpm) Speed is proportional to the gear ratio of the system. If the input gear has more teeth than the output gear, the result will be increase in speed at the output shaft. On the other Generally speaking, the reduction ratio can be simply hand, having the reverse scenario with more gear teeth at explained by the formula: Reduction Ratio = RPM-servo the output compared to the input will...

Vertex Precision Calculation of required Torque The lifetime of a planetary gearbox depends on calculation of required torque, also needs to be considered the peak torque happened in accelerating or decelerating should be less than the maximum load torque of a planetary gearbox. Min. torque required at moment of starting, that gear reducer should bear against peak torque at moment. The static torque of load reflected motor rotor. T load TL= (RXEFF) EFF= efficiency The time required in accelerate/decelerate. Rotary inertia of motor rotor The rotary inertia of load reflected motor rotor. motor...
