Compact VE5 Worm Gear Slew Drive With Electric Motor For Solar
Heating System
Worm Gear Slew Drive Description
The trough solar thermal power generation technology concentrates
the sunlight on the focal line through a trough parabolic
concentrating mirror, and collector is installed on the focal line.
To absorb the solar radiant energy after focusing. After the fluid
in the tube is heated, it flows through the heat exchanger to heat
the water to generate steam, which is generated by means of a steam
power cycle. The trough solar thermal power generation system
mainly includes a heat collecting system, a heat storage system, a
heat exchange system, and a power generation system. The heat
collecting system is mainly composed of a heat collecting tube, a
collecting mirror surface, a supporting structure and a control
system. The slew drives are the key part in the supporting
structure.
