A maintenance-free dry-running slewing ring structure for sun tracking

Abstract

The invention discloses a maintenance-free dry-running slewing bearing structure for sun tracking, which comprises a housing, a drive motor, and a worm and a turbine arranged in the housing and meshing with each other. The housings corresponding to the two ends of the worm are provided with The left and right glands are respectively provided with left and right stepped sliding sleeves made of engineering plastics between the left and right glands and the worm, and the left and right stepped sliding sleeves are respectively connected to the corresponding left and right The right gland is tightly fitted to form an integral structure. The inner walls of the left and right stepped sliding bushings are attached to the worm, and the worm can rotate relative to the left and right stepped sliding bushings. The threaded surface is injection-molded with engineering plastics and has a compound layer. By analyzing the operation mode of the sun tracker and combining the characteristics of modern engineering plastics and composite technology, the present invention makes a maintenance-free dry running design for the slewing bearing used for sun tracking, so that it can completely get rid of the trouble of lubrication failure and ensure Its long-term reliable operation.

Description

technical field [0001] The invention belongs to the technical field of solar tracking, in particular to a maintenance-free dry running slewing bearing structure for solar tracking. Background technique [0002] At present, the slewing bearing structure is widely used in the field of solar tracking, such as figure 1 and 2 As shown, the drive motor 2 drives the worm 3 to rotate, the worm 3 drives the turbine to rotate, and the worm is fixed with the housing 1 through tapered roller bearings 8 installed at both ends of the worm to limit the axial and radial movement of the worm, and only keep the rotation , so as to realize the relative rotation relationship between the casing and the turbine, and finally achieve the purpose of driving the solar component to align with the sun. [0003] In the above structure, the worm, turbine and tapered roller bearings must be lubricated, usually lubricated with grease, because the use of this structure is in a relatively remote outdoor, t...

AI Technical Summary

Problems solved by technology

[0003] In the above structure, the worm, turbine and tapered roller bearings must be lubricated, and grease is usually used for lubrication. Since this structure is used in relatively remote outdoors, the environment is harsh, and maintenance is very inconvenient. In addition, rain, snow, wind and sand, etc. Due to the effect of the natural environment, the grease will generally fail in 3 to 5 years, resulting in equipment failure
