Planetary gearbox PGH142

Changing the carrier and sun gear allows one to readily adjust the PGH142 planetary gears to various ratios. Planetary gear trains are regarded to be rather strong designs since the planetary gears are evenly spaced around the sun gear. A sun gear, planetary gears, ring gear and planetary carrier make up Planetary Gears' gear system. With the planetary gears spinning around the sun gear and meshing with the ring gear, its working concept is rather like that of the solar system. Multiple planetary gears share the load of this compact gear structure, which can achieve a great reduction ratio and high torque output in a limited area. Its high transmission accuracy depends on exact meshing between gears to guarantee correct power flow. Moreover highly dependable and long-lasting, planetary gears can run steadily under appropriate lubrication. Control of speed and torque: basic principle The planetary gearbox in the spindle drive system of the machine tool can efficiently change the spindle's torque and speed. The planetary gearbox uses internal gear's changing transmission ratio to accomplish this. For a planetary gearbox with various sun gear teeth, planetary gear and ring gear, for instance, a range of transmission ratios can be obtained depending on different connection and fixing techniques when the motor is connected to the sun gear as input. A lower speed and a higher torque are needed for rough machining-that is, milling the blank of a big workpiece. The planetary gearbox can now set a bigger reduction ratio to transform the high-speed and low-torque output of the motor into a low-speed and high-torque output fit for rough machining.
