SE1 Small Slewing Drive Use High Strength Nitride Steel For Solar
Tracking System
High Strength Slewing Drive
Heat Treatment of Slewing Drive
Raceway heat treatment: The raceways of the slewing bearing are
surface-inductively quenched, and the quenching hardness is ensured
at HRC 55-62, which can achieve sufficient depth of hardened layer.
Gear heat treatment: Due to the need to transmit force, one of the
slewing rings usually has teeth. The heat treatment state of the
gear is generally normalized or tempered. The tooth surface can
also be quenched according to the user's requirements. The
quenching hardness is between 50 and 60 HRC and sufficient depth
can be guaranteed. Gear quenching can be divided into full tooth
quenching and single tooth induction hardening depending on the
application. Single-tooth induction hardening can be divided into
tooth surface root quenching and tooth surface quenching.

Applications
Flat uniaxial application
The flat single-axis tracking bracket is a form of tracking bracket
with north-south arrangement and east-west tracking. According to
the astronomical algorithm, the motor drives the bracket to make
the module track the azimuth angle of the sun, increase the direct
component of sunlight on the surface of the photovoltaic module,
and then increase the power generation.
