Outdoor Use IP66 Dual Axis Slew Drive For Thermal Power Plant And PV Tracking System​

Dual Axis Slew Drive Description

The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together.Slewing drives are made by manufacturing gearing,bearings, seals, housing, motor and other auxiliary components and assembling them into a finished gearbox. Slewing drive is widely applied in modular trailers, cranes, timber grab equipment,aerial working platform, solartracking systems wind power systems, etc. Slewing drive is suitable for high-latitude areas and the eÜciency of power generation will be increased over 35%,which signiÚcantly improve the effciency of solar power generation system.

For horizontal single-axis solar tracking system, the main shaft of solar panel will adjust the angle to precisely track the declination angle. This kind of slewing drive is only applied for low latitudes area.

By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. Slewing drive is widely applied in solar tracking systems.

How to choose the proper size of slewing drives?

Choosing a proper size of the slewing drives in order to avoid from not only performance lack or performance surplus is play an important role in achieving cost effective solutions.

Please give us the following information in order to select a suitable slewing drive:

1. the application

2. the output toque required. If you do not have a clear idea of that data, just tell us the load, for example, the weight of panels and the mounting brackets on our slewing drive.

3. the load dimensions and the biggest wind in your area in the past 10 years which are used to calculate if the drive we recommended could bear the maxium load when there comes the big wind.

4. the output speed you required which will help us to recommend the suitable motors for you.

5. other informations such as backlash, IP grade demand etc

Application

The solar tracking system is divided into horizontal single-axis solar tracking system, tilted single-axis tracker and dual axis solar tracking system.
The slewing drives which are used in solar tracking systems are mainly single axis (SE series), dual axis (SDE series) and vertical type (VE series). And the most common used models are SE3, SE5, SE7, SE9; SDE3, SDE7 , VE7, VE9.
