5 Things to Know About Planetary Gearbox

A gearbox is a mechanical device used to set an application in motion. It is capable of providing a great amount of output torque. For example, the gearbox plays a vital role in producing motion in a vehicle. It changes the engine speed of a vehicle into torque when running on a hill. This is why it is also referred to as torque converter.

Speaking of gearboxes, you can find a variety of them on the market, each with its own distinctive characteristics. However, one of the most used gearboxes is the planetary gearbox.

A planetary gearbox is highly efficient, stable, and offers many benefits. Today, this particular gearbox is used in a plethora of applications.

If you do not know about gearboxes then you have landed on the right page. Here are 5 things to know about planetary gearbox:

1. What Is A Planetary Gearbox?

It’s a gearbox that has its input and output shaft aligned. A large amount of torque is transferred by this gearbox in applications to provide a strong motion.

For example, a bicycle’s acceleration hub uses a planetary gearbox to derive a lot of power. A bicycle with a 3-speed hub requires a single planetary gear. On the other hand, a bicycle with a 5-speed hub uses two gearboxes.

This type of gearbox consists of three parts: a ring gear, sun gear, and planetary gears. The ring gear houses the sun gear and planetary gears.

The ring gear is the largest ring in this gearbox and consists of inward facing teeth. On the other hand, the sun gear is in the middle and is surrounded by planetary gears that mesh with both the sun and the ring gear to produce torque.

2. Why Is It Called The Planetary Gearbox?

The arrangement gives this gearbox its name. It appears like the solar system where the planets orbit the sun.

3. Uses Of a Planetary Gearbox

The planetary gearbox is used in a multitude of applications and in various industries.

• In packaging machines.
• To reduce the speed of rollers in a printing press.
• To increase torque in a machine/robot.
• In EOT cranes.
• In the automation system.
• In automobiles.
• For precise positioning.
• In turbine engines.
• In toys, clocks, etc.

4. Things To Consider When Buying A Planetary Gearbox

There are many manufacturers on the market and each claim to be selling top-notch planetary gearboxes. This can be confusing and make it difficult to choose one.

To make this easier, there are certain factors that must be taken into consideration when buying a planetary gearbox.

• Load: Planetary gearbox can bear extreme loads easily because they distribute the load equally among the respective planetary gears. However, one must choose a gearbox by considering the amount of load they want on output.

Manufacturers have different means of measuring load which is why you need to determine the radial load and maximum axial for the type of application you want a gearbox installed in.

• Driving Torque: Apart from the load, another important parameter is the output torque. If you want a planetary gearbox that has greater torque then choose one that offers a high RPM.

• Durability: Your money could go to waste if you choose a planetary gearbox made up of poor material. They are manufactured in various materials such as steel, brass, aluminum.

Aluminum and brass gearboxes are more suitable as they run for longer and produce less noise compared to steel gearboxes.

Moreover, choose one that offers corrosion resistance because such gearboxes have a longer lifespan.

• Quality: Gearboxes equipped with high-quality needle bearings are said to operate smoothly and without making any noise.

PowerjackMotion is a good option if you are looking for reliable products. The company is known for producing high-quality products that have several uses and are highly durable as well.

5. Increasing Operation Speed And Lifespan Of A Planetary Gearbox

Since a gearbox is a mechanical device that has teeth meshing against each other to produce torque, jamming and struggling components can become a problem with everyday use.

This can be solved with the right kind of lubrication. You can use oil, gel or grease to enhance the movement of the gears. This will not only improve the speed but will also decrease the noise, if it’s making any.

Moreover, a properly and timely lubricated planetary gearbox is meant to run for many years without suffering any problems.

The Conclusion Planetary gearboxes are efficient torque producers that are used in many applications. Make sure to choose a reliable manufacturer when buying one.
