How to work and specifications of sew Planetary gearbox

The SEW brand Planetary gearbox is a type of industrial gearbox that is used in heavy industries. These gearboxes consist of three main components : sun gear , ring gear and spur gear .

The Planetary gear is located in the center and is responsible for power transmission. The ring gear is placed around the sun gear and transfers the power from the sun gear to the idler gear. Idler gears also transfer the force from the ring gear to the output shaft.

When a force is applied to the input shaft, the sun gear rotates and this rotation causes the idler gears to rotate as well. The idler gears rotate the ring gear with their rotation, and finally the rotation of the ring gear causes the output shaft to rotate as well.

Table of technical specifications of SEW Planetary gearbox

Torque : The torque of these gearboxes ranges from 25,000 to 651,000 Nm.
Conversion ratio: The conversion ratio of sew Planetary gearbox varies from 100 to 4000.
Efficiency: The efficiency of these gearboxes is up to 98%.
Voice: The noise of this type of gearbox is very low.
High torque tolerance: Due to the presence of a set of gears, they have the ability to withstand high torque.
High accuracy and low slack: These gearboxes have high accuracy and low backlash.
The ability to install in a location with limited space: Due to their compact design, they have the ability to be installed in a small and limited space.
Type of gearbox: The body is made of cast iron or steel and the gears are made of steel.

The conversion ratio of the Planetary gearbox is determined according to the number of idler gears. The higher the number of idler gears, the higher the conversion ratio.

Types and series of Planetary gearboxes of SAW brand

SEW Planetary gearboxes are produced and supplied in 3 series, which are:

P series:

This series of gearboxes are designed for general applications. They have a torque of up to 25,000 Nm and a conversion ratio of up to 1,000.

XP series:

This series of SEW Planetary gearboxes are designed for heavy duty applications. They have a torque of up to 651,000 Nm and a conversion ratio of up to 4,000.

PX series:

This series of gearboxes is a combination of the features of the P and XP series. They have a torque of up to 450,000 Nm and a conversion ratio of up to 2,000.

Each of these series has different models that are selected according to the needs of the user. Discuss your needs with technical experts so that they can offer you the best gearbox model.

Other names of SEW gearbox

In addition to being known as a planetary or star gearbox , the SEW Planetary gearbox is also known by other names, including:

    • Hiploid gearbox
    •  Planetary gear gearbox – ring gear
    • Idle gear gearbox

Hiploid gearbox is another name for Planetary gearbox. This name is derived from the English word “hypoid” which means “under the axis”. This name is given to the sun gear because the sun gear is located below the ring gear.

 Planetary gear gearbox is another name for Planetary gearbox. This name is given to the Planetary gearbox because there are two main types of gears in this gearbox: sun gear and ring gear.

The name of the spur gear gearbox is given to the Planetary gearbox because the spur gears in this gearbox play an important role in power transmission.

In general, the SEW Planetary gearbox is known by various names, all of which refer to the features of this gearbox.
