9 Inch Vertical Envelope Slew Gearbox For Horizontal Single Axis Solar Trackers
Vertical Envelope Slew Gearbox Description
Our slewing drive can simultaneously bear the effects of axial force, radial force and tilting moment, since the core component of the slewing drives adopt envelop wrom and multi tooth contact. Compared with traditional slewing products, our products have the characteristics of simple installation, easy maintenance, and saving installation space to a greater extent.
According to the openness of the slewing drive transmission mechanism, the slewing drive can be divided into open type and closed type. Usually, the open type structure is mostly used in applications where the environment is too harsh and the maintenance and maintenance cycle is short, and the open type structure is more convenient for parts. inspection, maintenance and maintenance, and more convenient replacement. On the other hand, where the environmental conditions do not change much and the environmental pollution level is below the medium level, the closed structure can provide a longer maintenance life cycle.

Glossary of Key Paramaters
Tilting Moment Torque: This torque is the gravity load multiplied by distance between the position of load and the center of slewing bearing. If the actual torque is greater than the rated tilting moment torque, slewing drive will be overturned.
Radial load: The load vertical to the axis of slewing bearing
Axial load: The 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, it is also seen as broken torque.
Self-locking: Only when there is load, the slewing drive is not able to reverse rotate and thus called self-locking.
