What is a planetary gearbox

Do you know that one of the principles of many of the most innovative technological developments of this era has a history of a thousand years? Robotics, 3D printing, and new forms of transportation all have one thing in common: they are often driven by a planetary gearbox.

As a supplier of planetary gearboxes (Apex Dynamics), we certainly know all the technicalities, but what do you do if you encounter this technique for the first time? We have decided to make it clear to everyone
One of the most widely used industrial tools is the planetary gearbox, also known as solar gear or solar gearbox.

planetary gearbox

One of the most widely used industrial tools is the planetary gearbox, also known as solar gear or solar gearbox.

What is the reason for naming the planetary gearbox?

Basically, the name of this gearbox is inspired by the arrangement and function of the gears inside the device. There are several simple gears in the center of this device, around which other gears (with internal and external teeth) are installed, and these gears regularly rotate around the simple gears in a circuit.

A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transmit the most torque in the least volume form (known as torque density).

Planetary gearbox components

Although planetary gearboxes have different models and series, there are some common components in all of them:

Housing:

It is a fixed member and has integral internal teeth. This part has the role of the ring gear in the device.

Solar pinion:

It is a driving member, which is installed in the center of the ring gear and is located on the output axis.

Mechanical connection to the motor shaft:

for this, the solar pinion is connected to a fastening system

Planetary carrier :

indicates the output shaft of the gearbox, a roller between the pinion and ring gear.

This device has a unique physical structure and by relying on it, you can achieve different speeds and torque transmission in different directions with the same structure.

In what devices is SEW used?


This device is used in many different environments. From food production and packaging factories to paper factories. Conveyor devices that continuously guide cans containing drinks in the production and packaging path, perform their duties using SEW gearboxes. Similar operations take place in paper factories. The cut wood is moved to other machines through the conveyor belt.

SEW

After performing the desired operation, the produced papers are transferred for packaging. Due to the high power of solar gear, it is possible to use it in various fields.

• Transportation in freight

• Suitable for construction industries

• Suitable for construction work

• Mining industries

• Mechanical industries

• Food industry

• Chemical and plastic industries

• Suitable for category lines

What points should be considered when buying a mobile gearbox?

When buying a solar gearbox, it is better to pay attention to the following points so that you can choose and prepare the best type for your activity.

installation location

This point is based on how to install the device, its size, and by far the minimum and maximum capabilities that that size device can provide.

According to this point, it should be decided whether it is possible to slip and shake hands, or whether it is necessary to install a base and screw the device to the ground or not?

The type of activity and the materials you use in the activity

Although the gearbox only has the role of producing energy and movement, if there is a heater of fluid in the workshop, or if a pump is used in or near the device where the gearbox is installed, then that fluid and its chemical characteristics should be considered. also noticed

For example, if it is possible to spread dangerous or corrosive substances during steam operation, this is one of the conditions that make you unable to choose any device.

Weather conditions of the installation environment

If there is a lot of humidity or a lot of dust in that environment, people are either forced to prepare a resistant shell or have to use more resistant devices.

The price and cost you can spend on this

In many small and start-up jobs that have to provide this device with initial capital, we recommend this group of people to go to domestic brands because during these years, due to the difficult economic conditions, these manufacturers have been able to have gained more customers and because of this the quality of their products has increased.

Ability and the desired output from the device

In many activities, there is a minimum and maximum output and the device should not go out of this range, in this case, people are suggested to choose the device wisely and if they do not have enough information, seek advice from a knowledgeable person.

In many activities, there is a maximum for using energy and the device should not exceed this limit, that is why these people should be more sensitive and only buy devices that are made with newer technologies.

Important points of maintenance of mobile gearboxes

The industrial gearbox needs lubrication

As you know, the gearbox consists of a large number of gears, and for the gears to easily mesh with each other and rotate, it is necessary to have a slippery liquid between them, and in addition to simplifying the movement, it also prevents the corrosion of the gears. Of course, it should be said that all machines that produce friction and heat need lubrication. Ensuring gearbox lubrication reduces the possibility of wear and breakage and increases the lifespan of gearbox parts. Therefore, check the gearbox regularly and at specific and regular intervals and make sure that its oil level is always in the right amount.

The gearbox and its surroundings must be clean

All gearboxes have a device called a breather. The air intake is one of the essential components in a gearbox. If the air trap is not installed, the increase in pressure inside the industrial gearbox shell can cause oil leakage from one or more parts of the seal. By allowing hot air to escape and fresh air to enter, the air intake prevents pressure inside the gearbox shell.

Make sure these vents are in place to prevent dust and particles from entering the gearbox. Things like dirt, water and other extra particles that enter the gearbox can seriously damage it and sometimes cause serious problems in the work process. Most of the time, the gearbox is used in places where getting dirty is unavoidable. You must clean the dirty gearbox quickly or prevent it from getting dirty at all. The best solution is to always try to keep your workplace and workshop away from pollution and garbage.

Coolants are vital to the transmission

The industrial gearbox generates a lot of heat when working. Without proper cooling, this heat can be harmful. One of the main causes of overheating of the industrial gearbox is the lack of proper lubrication of the device. Accordingly, the device should be lubricated at regular times with the right oil and its type to avoid heat for this reason.

Check your device for signs of overheating. Check if the oil you use properly lubricates the parts of your industrial gearbox. If you use the wrong oil, it cannot prevent friction properly. This factor may be the cause of overheating. Try to find a quality oil that is recommended for the type of transmission you are looking for.
