Abstract

The invention discloses a built-in solar tracking azimuth driving device which comprises a circular box cover, an inner tooth type four-point contact ball turntable bearing, a worm rod, a turbine worm rod-bevel gear speed reducer component and an output short shaft, wherein the circular box cover is fixed on the position at the top end in a hollow vertical column; the speed reducer component is mounted on the lower part of the circular box cover; the output short shaft of the speed reducer component is upward; an external gear is mounted on the short shaft; the external gear is meshed with the inner tooth type four-point contact ball turntable bearing; the worm rod is arranged in the speed reducer component; an input end of the worm rod is connected with a motor; a variable parameter is set according to the requirement for the outline structure size and reduction ratio of the device. According to the invention, different reduction ratios can be easily realized through the driving pair parameter design, and meanwhile, a triple-axle bearing structure and an inside mounting mode of the vertical column can ensure that the larger wind load overturning moment, axial force and radial force can be endured by the device.

Description

technical field [0001] The invention relates to an azimuth transmission device, in particular to a built-in sun tracking azimuth transmission device. Background technique [0002] The azimuth transmission device is an important part of solar power generation, and it is the actuator that realizes high-precision tracking of the solar collector. The azimuth transmission device not only requires stable operation, high efficiency, low noise, and long life, but also requires the device not to interfere with the truss. Space movement, simple and clear appearance makes the overall structure of the rack clear. [0003] At present, the azimuth transmission device of the dish solar energy is driven by a worm gear, and a slewing bearing is used to realize relative rotation between the two parts of the column and the grid frame. At the same time, it can withstand a certain axial force, radial force and wind load overturning moment. Gear reduction mechanism and three-stage reduction DC ...
