Single Axis SE1 - SE25 Solar Tracker Slew Drive With 24VDC Gear
Motor For Solar Tracking System
Description
Slewing ring, also known as slewing bearings or turntable bearing,
is a large bearing which is able to sustain the more axial load,
radial load and tilting moment. It is known as: “machine joints”,
the essential machinery transmission parts, between the two objects
that need to be relative rotary motion. It has the inner and outer
ring, rolling and other components.
One can consider the slewing drive as a gearbox because the core
motion components are the slewing bearing and worm shaft. It also
consists of auxiliary components such as seals, housing, and motor.
As a power source, slew motor is usually DC planetary gear motor or
AC gear motor. AC hydraulic motor is mainly used in the
construction machinery as a power drive system. As the core
component is slewing ring drive, slewing gearbox can readily
withstand the axial and radial forces. The slew drive working
principle: The worm is driven by the motor, which drives the outer
ring of the slewing ring to rotate; The outer ring output the
torque through the flange and the inner ring of the slewing ring is
fixed in the housing.
Slewing drive has reverse self-locking because of worm gear drive
with reverse self-locking characteristics. This feature greatly
enhances the stability of the host operating and safety factor.
Compared to the traditional swing products, slewing drive gearbox
is easy to install, easy to maintain, and saves considerable
installation space.
Slewing Drive Advantages
1. Hourglass worm technology provides more tooth contact, higher
torque
2. Provide an economical and compact solution with low maintenance
costs
3. Slewing gear and raceway harden processing technology increase
the slew drive lifetime
4. All slewing mechanism components are rigorously tested and have
good quality assurance
5. Custom design is available
