Self-Locking Electric Slewing Drives Reducer For 30 Year Field Life
PV Tracking System
Self-Locking Electric Slewing Drives Description
Slewing drive or slewing ring can be treated as a gearbox because
the core components are the slewing bearing and worm shaft. It also
consists of auxiliary components such as seals, housing, and motor.
The motor is usually DC planetary gear motor, AC gear motor or
hydraulic motor.
The slewing drive device has the overall high protection and
stability suitable for the harsh outdoor environment. The
maintenance-free actuator slewing drive device has an overall
protection level of not lower than IP65, and can operate stably for
a long time in harsh outdoor environments.
Features
1. Reverse self-locking characteristic which greatly enhances the
stability of the system and increase safety factor.
2. Easy to install, easy to maintain, and saves considerable
installation space
3. Adopts hourglass worm technology which provides more tooth
contact, thus higher torque
4. The harden processing technology to increase the slewing drive's
field life.

Applications
The advent of the era of affordable Internet access has prompted
investment companies to adopt various new technologies to reduce
the cost of electricity. The tracking bracket is a new technology
that has been favored in the past one or two years and can reduce
the cost of electricity.
Types of PV Tracking Mounts
There are roughly five types of photovoltaic power station
brackets:
1) Best inclination fixed type (the most widely used before)
2) Flat single-axis tracking type (the most widely used tracking
bracket at present)
3) Inclined single axis tracking type
4) Dual axis tracking type
5) Fixed adjustable type (the amount of application is second only
to the fixed bracket, and it is also divided into various forms
The most fundamental difference between different operation modes
is their power generation difference. Of course, the initial
investment and operation and maintenance costs will also vary.
