VE6 Envelope Worm Gear Slewing Drive For Horizontal Single Axis Solar Tracking System
Envelope Worm Gear Slewing Drive Description
In recent years, more and more attention has been paid to the development of low-carbon, environmental protection, and renewable energy. As a clean and pollution-free energy source, solar energy has a very broad development prospect, and it has become a green energy that all countries are competing to develop. However, solar energy has problems such as low density, intermittentness, and continuous changes in light direction and intensity over time. Traditional solar panels are mostly installed in a fixed manner, that is, the panels are fixed at a certain angle and do not change with the position of the sun, which seriously affects the photoelectric conversion efficiency. The output power of the photovoltaic array will be reduced by about 10% due to the reduction of the radiant energy incident vertically. Throughout the year, spring, summer, autumn and winter, from day to night, the rising and setting of the sun and the angle of the sun's rays change all the time. Therefore, how to change the angle of the battery panel with the angle of light to increase the photovoltaic conversion rate. This requires the use of a rotary drive device, which can change the position and angle of the battery panel to achieve the intensity of the sun's rays perpendicular to the light intensity of the battery panel, thereby increasing the photovoltaic conversion rate. So the tracking system plays an important role and application of the slewing bearing in the solar slewing drive device.
The slewing drive device is a new type of slewing product, usually composed of slewing bearings, worms, motors, shells and other parts. It not only has the functions of connecting, rotating and supporting slewing bearings, but also has the compact structure and output torque of worm drive. The advantages of large, stable transmission, long service life, easy installation, a large amount of installation space saving, easy maintenance, can greatly save costs.
The slewing drive device saves the user installation time because of the modular operation, and the centralized function also facilitates the designer's product design. At present, it is widely used in industrial robots, solar power generation and other fields.
