Product Description

Slewing drive gear motor worm drive for horizontal single-axis solar tracking 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.

Slew Drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new slewing drive features easy installation, easy maintenance and a greater degree of installation space.

Slew Drive are widely used in PV, CPV, STP solar tracking systems and construction applications including truck cranes, manlifts, turntables, port machinery, modular vehicles, small wind power systems and satellite communications.

Technical Glossary

  • Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the torque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
  • Radial load: Load vertical to the axis of slewing bearing.
  • Axial load: Load parallel to the axis of slewing bearing.
  • Holding torque: It is the reverse torque. When the drive is rotating reversely, and parts are not damaged, the maximum torque achieved is called holding torque.
  • Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.

Slewing Drive Overview

Frequently Asked Questions

What is the primary function of a slewing drive in solar tracking?
It acts as a main rotating component that adjusts the solar panels' angle to precisely follow the sun's movement, significantly increasing energy absorption efficiency.
What materials are used in the construction?
We use high-quality 42CrMo for the worm and 50Mn for the slewing bearing, both treated for high wear resistance and durability.
Is the slewing drive protected against outdoor environments?
Yes, our drives feature an IP65 rating and C3 corrosion protection, making them ideal for harsh outdoor solar farm conditions.
What is "Holding Torque"?
Holding torque is the maximum reverse torque the drive can withstand without damaging the components while the drive is not rotating.
Can these drives handle both axial and radial loads?
Yes, the core slewing bearing design allows the unit to simultaneously withstand axial forces, radial forces, and overturning moments.
Do you offer custom production?
Yes, we accept both standard and non-standard production requirements to fit specific project needs.
