What is a planetary shaft gearbox?
Planetary Gearboxes are a type of gearbox where the input and output both have the same centre of rotation. This means that the centre of the input gear revolves around the centre of the output gear and the input and output shafts are aligned.
What is the function of planetary gear unit?
Generally, planetary gears are used as speed reducers. They are used to slow down motors and increase the torque. Torque is the working power of the machine.
What is a 2 stage gearbox?
For most single-stage gearboxes, the directions of rotation of the input and output shafts are opposite, while for two-stage gearboxes, the additional change in direction by the second stage puts the output shaft rotation the same as the input shaft, as shown in the illustration below.
How do you measure a planetary gearbox?
First Steps. To make calculating planetary gear ratios as simple as possible, note the number of teeth on the sun and ring gears. Next, add the two numbers together: The sum of the two gears’ teeth equals the number of teeth on the planetary gears connected to the carrier.
Which component uses planetary gears?
Planetary gear train (PGT) has been widely used in the transmissions of helicopters, automobiles, wind turbine, aircraft engines, etc. The main advantages of this transmission are its high efficiency, its compactness, its large transmission ratio and its large power-to-weight ratio, etc.
What are the different types of planetary gearboxes?
Servo Gearboxes Low-backlash Planetary Gearboxes NP / NPL / NPS / NPT / NPR NP / NPL / NPS / NPT / NPR planetary gearbox NP – Planetary gearbox with LP+output geometry
What is a SP + high speed planetary gearbox?
The standard version of these low-backlash planetary gearboxes with output shaft is ideally suited for high positioning accuracy and highly dynamic cyclic operation. The SP + HIGH SPEED is particularly well suited for applications with maximum speeds during continuous operation.
What is a NPT gearbox?
