Technical field
The invention belongs to solar energy tracking technical field, particularly a kind of maintenance-free dry for solar tracking runs pivoting support structure.
Background technique
At present, pivoting support structure is widely used in solar energy tracking field, as illustrated in fig. 1 and 2, drive motor 2 drives worm screw 3 to rotate, and worm screw 3 drives turbine rotation, and worm screw is fixed with housing 1 by the tapered roller bearing 8 being arranged on its two ends, to limit axis and the radial motion of worm screw, and only retain rotation, thus realize relatively rotating relation between housing and turbine, finally reach the object driving solar elements to aim at the sun.
Lubrication must be had in worm screw and turbine and tapered roller bearing in said structure, usual employing grease lubrication, because this structure place to use is all in more remote open air, environment is more severe, it is very inconvenient to safeguard, add the effect of the physical environment such as sleet, dust storm, lubricating grease generally will lose efficacy in 3 to 5 years, thus caused equipment failure.
Summary of the invention
The object of the invention is to: for above-mentioned Problems existing, provide a kind of maintenance-free dry for solar tracking broken down because of lubrication failure that can thoroughly solve to run pivoting support structure.
Technological scheme of the present invention is achieved in that a kind of maintenance-free dry for solar tracking runs pivoting support structure, comprise housing, drive motor and being arranged in housing and intermeshing worm screw and turbine, described worm screw is connected with drive motor clutch end, the housing that described worm screw two ends are corresponding is provided with a left side, right gland, it is characterized in that: on a described left side, the left side that engineering plastics manufacture is respectively arranged with between right gland and worm screw, right step type sliding shaft sleeve, a described left side, right step type sliding shaft sleeve respectively with a corresponding left side, right gland drive fit forms overall structure, a described left side, inwall and the worm screw of right step type sliding shaft sleeve are fitted, and described worm screw can relative to a left side, right step type sliding shaft sleeve rotates, a described left side, right gland is by a left side, right step type sliding shaft sleeve is pressed on ledge structure place corresponding to worm screw two end part, engineering plastics are adopted to be injected with composite bed at the flank of thread of described worm screw or turbine.
Maintenance-free dry for solar tracking of the present invention runs pivoting support structure, and it is outside described left and right step type sliding shaft sleeve, be respectively arranged with sealing configuration between worm screw and left and right gland.
The present invention is by the analysis to sun tracker operating mode, simultaneously in conjunction with the feature of modern project plastics and complex technique, maintenance-free dry operating energy loss has been done to the pivoting support for solar tracking, make it thoroughly to have broken away from the puzzlement of lubrication failure, ensure its operation reliably and with long-term, single worm structure of this design can be used for low tracking accuracy requirement, and twin worm structure can be used for high precision tracking.
