We invite you to familiarize yourself with the offer of our company, which is the official distributor of STM in Ukraine. In our product range, you can find high quality planetary series STM gearboxes that are popular all over the world.

Features of the operation of planetary gearboxes

The planetary gearbox uses a gear type of transmission of rotary motion. This type is also called solar, since it is built on the principle of movement in the solar system, where the central wheel drives the rest of the satellites that are in direct contact with it – adhesion. In this case, the central sun wheel is rigidly fixed to the heart of the mechanism. But there is also a planetary gearbox of a different design, when a fixed crown wheel is installed on the periphery of the device and the movement of the sun wheel occurs due to the rotations of the planetary parts, which are initiated by an external source. In this case, the load on the central shaft is reduced.

Also, the planetary gearbox can be equipped with an electric motor or a hydraulic motor. The planetary gear motor has a compact housing, is lightweight and is capable of transmitting high torque at low speeds. Planetary gearboxes, due to their operating principle, are used in a wide variety of areas and equipment. The most popular are:

Tower and gantry cranes. The planetary gearbox is installed on the boom swing mechanism, trolley movement and crane movement mechanism
The planetary gearbox is used as a slewing mechanism providing very high torque and significant reduction in size.
Treatment facilities
Planetary gear motor is used to drive aeration plants
Equipment for pulp and paper mills
In metallurgy
Shredders and shredders
Bending machines
Drilling rigs
Tunneling machines and mining equipment
Swing gear reducers;
Winch gearboxes;
Reducers for tracked devices;
Gearboxes for all wheel drives.
How to choose a planetary gearbox?

Before buying a gearbox, you need to decide what tasks it has to perform, since several characteristics of the purchase depend on this:

Construction type;
Required characteristics
Price;
Terms of manufacture and installation;
Options.
When choosing the type of mechanism, one should take into account that it can have a wide variety of designs:

Depending on what gear ratio you want to get, there are one-, two- and three-stage planetary gearboxes.
Shaft options can be either solid or hollow.
Mounting performance and requirements for operating conditions.
A planetary gearbox can be combined with other types of gearboxes: worm, bevel or cylindrical.
There are possibilities to equip a planetary gearbox with an electric motor or a hydraulic motor.

You should definitely pay attention to the brand of the mechanism, since not all manufacturers can boast of a wide range of products in this type of product, especially in a variety of designs. Therefore, if a gearbox of a specific design is needed, it is worth contacting the manufacturer, like STM.

The main advantages of STM planetary gearboxes

We invite you to pay attention to the versatility of European-style planetary gearboxes manufactured by STM.

The main advantages of using these mechanisms are:

High percentage of efficiency, which is 90%;
The planetary gearbox and planetary gearmotor are much more compact than other gearboxes and have a significantly lower weight of their counterparts of the corresponding technical parameters.
Standard torques up to 4,500,000 Nm
26 standard sizes of planetary gearboxes and planetary gear motor coaxial and angular;
The compact dimensions of the gearbox can significantly save production areas;
Despite its small dimensions, the gearbox has high power and high load capacity;
Due to their increased wear resistance, planetary gearboxes can work in the most difficult conditions;
The gearbox is assembled on a modular basis, which simplifies the process of its assembly and maintenance, and also reduces the time for this;
The production of STM planetary gearboxes takes place in a very short time.
Ease of installation
Wide range of configurations and options
Short terms of production and shipment

It is also important that STM planetary gearboxes are very flexible in terms of design and can easily replace other devices made by other manufacturers without sacrificing performance.
