7 Inches Vertical Single Worm Slew Drive For Solar Energy Tilting Tracking System
Solar Tracker Slew Drive Description
The single axis vertical slew drives are mounted vertically, it is
specifically designed for flat single axis solar tracking systems
that require tracking towards the sun for east to west. The precise
rotation of the vertical slew drive allows the mechanism to track
perfectly. This kind of vertical slewing drive is manufactured
using the latest technology which incorporates hourglass mechanism.

Q&A
How long is the life of the rotary reducer in general? How should
the power station be properly maintained during its operation?
The slewing drives' design and laboratory data meet the
25-year transmission life. Depending on the application, the grease
in the slewing drive needs to be changed regularly.
During the working process, what are the possible problems of the
rotary reducer?
During the working process, under the premise of reasonable design
and selection, the most likely problem of the rotary reducer is
"the shortening of the actual service life". The actual service
life here refers to the selection of sealing, heat treatment or
materials. If the control is not in place, various problems will
occur after the reducer is used for a period of time, such as
reduced accuracy, rust, water ingress, oil leakage, and stuck.
What is the solution?
From the early stage design, process, manufacturing to the later
stage of on-site installation error proofing, and then to operation
and maintenance, grasp every detail well, and minimize or avoid the
potential quality problems of the rotary reducer.
