9 Inches Vertical Slewing Drive Worm Drive Slew Ring For Open Field Solar Trackers
Single Axis Slewing Drive Description
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 selflocking.

Single Axis Slewing Drive Features
Single axis slewing drive is a reduction transmission mechanism integrated with a driving power source. The rotation can be in a single axis, or in multiple axes together. It is a general-purpose reduction transmission mechanism that integrates the functions of rotation, deceleration, and having a simple structure and convenient manufacture and maintenance at the same time.
Single Axis Slewing Drive Applications
Flat single axis tracking system
The flat single-axis tracking system is the most widely used tracking system on the market, which can be subdivided into the NS-axis flat single-axis tracking system (that is, the rotation axis is installed in the north-south direction) and the EW-axis flat single-axis tracking system (ie the rotation axis). installed in the east-west direction). Among them, the NS-axis flat single-axis tracking system is the most widely used.
For the NS-axis horizontal single-axis tracking system, in order to adapt to areas with higher latitudes, a flat single-axis tracking system with an inclination angle has been developed.
