What are Planetary Gears Used For? The planet carrier, ring gear, and bevel gear are all complicated pieces of machinery, which are put together in a way that allows them to manipulate the speed and torque of a vehicle. Essentially, they're useful for automatic transmissions because they allow the car to determine what gear it needs to be in.

A planetary gearset creates all the gear ratios that a transmission can produce. It gives vehicles with automatic transmission systems the ability to change gears smoothly as a vehicle reaches different speeds without having to move the gear shift like in a manual system. In other words, it facilitates the chief function of an automatic

5/18 · Planetary gears, also known as epicyclic gears, were invented by the Greeks about 2,000 years ago to aid in the prediction of planetary motions in the solar system. The most straightforward explanation for how they came up with the gear is that planetary gears are made up of central drive gear (i.e. the sun) and several "planet" gears that orbit around it.

Our planetary gear motors can provide high torque output with high efficiency. The standard voltage for our planetary gear motor is 8 VDC, 12 VDC, 16 VDC, 24 VDC, 36 VDC & 48 VDC. The diameter range from 16mm to 65mm. For continuous operation, the rated torque range from 1.2 to 418.63 mN.m. For stall torque, the range is from 6 to 10,010 mN.m.

The motion of planetary gear systems is expressed clearly in the Plantetary Train Equation: -S/R = (ωr-ωa)/ (ωs-ωa). Once this is known, the speeds of the carrier arm, sun and/or ring can be calculated. Multiple series of planetary gear systems can be used to get multiple speeds and directions. Planetary gear systems are used everywhere.

A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form (known as torque density). For a three-speed hub, a one-stage planetary gear system is used, for a five-speed hub a 2-stage. Each planet gear system has a reduction state, a direct coupling and an acceleration mode.
