High Precision Slewing Ring Bearing With Hydraulic Motor For Solar
Tracker System
Description
Slew bearing is a bearing that able to bear axial load, radial load
and overturning torque. Under normal circumstances, slewing rings
have their own mounting holes, lubricant holes and seal holes, to
meet the different needs of the various host working under the
various conditions.
Features
1. Gear ratio
The rotation of the slewing ring drive reduces the speed of the
driven member and also multiplies its torque and increasing it
proportionally as the speed decreases.The speed ratio of shafts
depends upon the relation of the number of threads on the worm to
the number of teeth in the worm wheel or gear.
2. Hourglass worm
Our slewing drives are using hourglass worm technology, in which
the worm is shaped to engage more teeth in the gear. This increased
tooth engagement results in greater strength, efficiency and
durability.
3. Function
Slewing drives function with standard worm technology, in which the
worm on the horizontal shaft acts as the driver for the gear, in
general, the shaft is driven by electric gear motor. And it is
self-locking.
Advantages
1. Rotation 360 degrees
2. Can attach a gear motor on left or right side
3. The gearing clearance is already set before factory
4. Simple installation and low maintenance
5. Compact design
6. Self-locking; no need for brake
7. Small backlash
